    Malawy for Defendants and Respondents.
    Appellant Colony Cove Properties, LLC, a Delaware limited liability
    company, is the owner of the Colony Cove Mobile Estates, a mobilehome park (the
    Park) containing approximately 400 spaces, located in respondent City of Carson
    (the City). At the time appellant purchased the Park, it was rent controlled.1
    Appellant submitted applications for rent increases in September 2007 and again in
    September 2008. After hearings in June 2008 and June 2009, respondent Carson
    Mobilehome Park Rental Review Board (the Board) approved increases in the
    monthly rent per unit of $36.74 and $25.02. Appellant contended that even after
    the rent increases approved by the Board, the rental income from Park residents
    was insufficient to cover its expenses, including interest payments on the $18
    million loan it had secured to purchase the Park. Appellant maintained that to
    avoid becoming confiscatory, rents must be set at a level sufficient to provide a
    profit after payment of debt service. In two separate proceedings before the trial
    court (consolidated for appeal), the court denied appellant‟s petitions for writ of
    administrative mandamus seeking to overturn the Board‟s determinations. We
    conclude that substantial evidence supported the determination that the rent levels
    set by the Board provided appellant a fair return. Accordingly, we affirm the trial
    court‟s decision denying the petitions. We reverse only that portion of the court‟s
    order striking appellants‟ reservation of their federal claims.
    1
    Shortly after purchasing the Park, appellant applied to convert the rental spaces to
    condominium-style ownership. The conversion was approved in 2009, permitting
    appellant to sell each space individually.
    2
    FACTUAL AND PROCEDURAL BACKGROUND
    A. Purchase of Property
    Appellant purchased the Park for $23,050,000 in April 2006, putting
    $5,050,000 down and financing the $18 million balance at a variable rate, which in
    2007 was approximately 7 percent.2 The Park had 404 spaces, of which 403 were
    available for rent.3 At the time of the sale, the Park‟s tenants were paying rents
    averaging $408 per space per month, and the Park‟s gross income totaled
    approximately $2.2 million per year, including miscellaneous income from sources
    other than rent. The Park‟s “net operating income” (a figure calculated by
    subtracting regular operating expenses, but not debt service, from gross income)
    was $1.1 million. The prior owner‟s debt service was approximately $350,000 per
    year, leaving over $700,000 in cash profit.
    B. Rent Control Ordinance
    Since 1979, the City of Carson has had a “Mobilehome Space Rent Control
    Ordinance” (Carson Mun. Code, § 4700 et seq.; (Ordinance)). The Ordinance
    requires the Board to “grant such rent increases as it determines to be fair, just and
    reasonable.” (Ord., § 4704(g).) In general, a rent increase is “fair, just and
    reasonable” if it “protects Homeowners from excessive rent increases and allows a
    fair return on investment to the Park Owner.” (Ibid.) The Ordinance sets forth
    certain non-exclusive factors the Board is to consider in determining whether to
    grant an owner‟s request for rent increases, including (1) changes in the consumer
    price index for consumers in the Los Angeles-Anaheim-Riverside area; (2) the rent
    charged for comparable mobilehome spaces in the City; (3) the length of time since
    2
    The prior owner had paid $3.5 million for the Park eleven years earlier.
    3
    The final space was used by the Park‟s resident manager.
    3
    the last Board determination of a rent increase application; (4) any capital
    improvements undertaken and completed; (5) changes in property taxes or other
    taxes; (6) changes in utility charges; (7) changes in reasonable operating and
    maintenance expenses; (8) unusual repairs; and (9) services provided. (Ibid.)
    The City has adopted “Guidelines for Implementation of the Mobilehome
    Space Rent Control Ordinance” (the Guidelines). The Guidelines provide that the
    factors in section 4704(g) of the Ordinance are to be used “to focus on changes in a
    park‟s income, expenses and circumstances, including changes in the general
    economy, to determine whether a rent increase is appropriate to allow the owner to
    keep earning a fair return . . . ,” that “[n]o one factor . . . is determinative,” and “the
    factors must be considered together and balanced in light of the purposes of the
    Ordinance and all the relevant evidence.” (Guidelines, §I(C-D).) The Guidelines
    further provide that “[t]he Board cannot reconsider its decisions on a rent
    adjustment application after they have been embodied in a formal written
    resolution setting forth the findings of the Board. Therefore, each rent increase
    application after the first application is evaluated only on the basis of changes in
    income, expenses, profit, the CPI, maintenance, amenities and services that have
    occurred since the date of the last increase approved by the Board.” (Id., ¶I.E.)
    With respect to debt service as an allowable expense, the Guidelines provide
    that allowable expenses include “[d]ebt service incurred prior to adoption of the
    Ordinance to purchase or operate the park” and “[d]ebt [s]ervice necessarily
    incurred to operate the park after adoption of the Ordinance . . . if the financing
    arrangements were prudent and consistent with customary business practice.”
    (Guidelines, § II(A)(2), subds. (d) & (e).) However, debt service incurred to
    purchase a park after adoption of the Ordinance is an allowable expense only if
    “the purchase price paid was reasonable in light of the customary financing
    practices,” and the applicant has “the burden of establishing the reasonableness of
    4
    the purchase price and financing procedures.” (Id., §II(A)(2), subd. (f).) The
    Guidelines explain: “The reason for these general rules is that passing on
    increased debt service due to purchase at prices above those that can be justified by
    the income earned by the park under rent control or incurred by unusual financing
    methods, such as 100% financing, would defeat the purpose of rent control.”
    (Ibid.)
    The Guidelines go on to state that “in evaluating a rent increase application,
    the Board may consider, in addition to the factors specified in § 4704(g) of the
    Ordinance, a „gross profits maintenance [GPM] analysis,‟ which compares the
    gross profit level expected from the last rent increase granted to the park prior to
    the current application („target profit‟) to the gross profit shown by the current
    application.” (Guidelines, §II(B).) According to the Guidelines, the GPM analysis
    is “intended to provide an estimate of whether a park is earning the profit estimated
    to provide a fair return, as established by the immediately prior rent increase, with
    some adjustment to reflect any increase in the CPI”; it is “an aid to assist the Board
    in applying the factors in the Ordinance,” and is “to be considered together with
    the factors in § 4704(g), other relevant evidence presented and the purposes of the
    Ordinance.” (Ibid.) The Guidelines expressly state that the GPM analysis is “not
    intended to create any entitlement to any particular rent increase.” (Ibid.)
    In October 2006, the Guidelines were amended to provide that the Board
    “may also consider, a „maintenance of net operating income [MNOI] analysis,‟
    which compares the net operating income (NOI) level expected from the last rent
    increase granted to a park owner and prior to any pending rent increase application
    (the so called „target NOI‟) to the NOI demonstrated in any pending rent increase
    5
    application.” 4 (Guidelines, §II(C).) Such MNOI analysis “is intended to provide
    another method to estimate whether any applicant for a rent increase is earning a
    constitutional fair return, as established by the immediately prior rent increase,
    with appropriate adjustment(s) to reflect changes in the CPI, and is a methodology
    approved by the courts in which changes in debt service expenses are not to be
    considered in the analysis (unlike a gross profits maintenance analysis, where such
    changes may be considered).” (Guidelines, §II(C)(2).)
    The Guidelines state that “[t]he Ordinance assumes that the profit earned by
    park owners when the Ordinance was adopted provided a fair return because it was
    based on rents chosen by the owners prior to the regulation” (Guidelines, §I(C))
    and further assumes that “park owners attempted to rebut that presumption when
    they first applied for an increase.” (Guidelines, §IV(A).) The Guidelines further
    explain: “Most applications submitted to the Board have been based on the factors
    in the Ordinance and Park Owners rarely offer evidence concerning their
    investment in a park, the return being earned on the park or the return being earned
    by comparable mobilehome parks.” (Ibid.) However, if an applicant believes “the
    park cannot earn a fair return without an increase greater than that permitted by
    application of the factors in the Ordinance,” he, she or it may attempt to rebut the
    presumption by presenting additional evidence not specifically related to the
    Ordinance factors, including (1) the date the park was purchased; (2) the purchase
    price; (3) the rents charged and the net operating income of the park prior to the
    purchase; (4) an appraisal of the park at the time of purchase; (5) the amount of the
    4
    As explained in Kavanau v. Santa Monica Rent Control Bd. (1997) 
    16 Cal.4th 761
    , 768-769 (Kavanau), the MNOI formula ensures that net operating income remains
    constant by permitting landlords to recoup increases in ongoing operating expenses. To
    prevent erosion of net operating income over time, the formula typically also includes an
    inflation adjustment component. (Ibid.)
    6
    down payment and/or current amount of equity; (6) any capital improvements
    made; and (7) the “Overall Rate of Return [defined as “ratio of net operating
    income to purchase price” of comparable] mobilehome parks in jurisdictions with
    and without rent control at the time of the application.” (Guidelines, § IV(A)
    (1-4).)
    The Guidelines expressly state: “[The Board] will not consider return based
    on the current fair market value of a park or the value of park property for purposes
    other than use as a mobilehome park.” (Guidelines, §IV(A)(4).) Further, “[s]ince
    mobilehome parks are unique investments, it is unlikely that the return on other
    types of investments would be found relevant by the Board. . . . . [T]he return on
    investments which do not have the potential for appreciation in value are not
    relevant.” (Ibid.) The Guidelines recognize that even comparison with other types
    of rental housing is of limited relevance because owners of mobilehome parks do
    not have the responsibility or expense of maintaining the actual housing units,
    mobilehome parks experience much lower vacancy rates than other types of
    rentals, and mobilehome park residents invest in improvements which enhance the
    owner‟s investment. (Ibid.)
    C. Appellant’s September 2007 (“Year 1”) Rent Increase Applications
    1. General Rent Increase Application
    a. Initial Calculation
    In September 2007, appellant submitted to the Board an application for a
    rent increase of $618.05 per space per month.5 The figure was derived from
    5
    The Board had granted a general rent increase of $6.23 per space per month in
    September 2006, bringing the average rental to $414. That increase and a $11.14 five-
    year capital improvement rent increase were the subjects of prior writ petitions and an
    appeal, Colony Cove Properties, LLC v. City of Carson Mobilehome Park Rental Review
    (Fn. continued on next page.)
    7
    calculations performed by appellant‟s expert, John P. Neet.6 Neet assumed that
    appellant was entitled to a 9 percent per year return on the $23,050,000 purchase
    price of the Park, or $2,074,500 per year.7 If appellant‟s debt service on the $18
    million loan used to purchase the Park was taken into account, the Park‟s current
    income was approximately $900,000 less than appellant‟s expenses.8 The
    requested rent increase would have resulted in almost $3 million in additional
    revenues every year. Neet called this calculation a “Net Operating Income
    (Including Debt Service)” analysis.
    This analysis was subsequently criticized by the Board‟s experts as
    “meaningless” and “mak[ing no] sense” because appellant did not have $23 million
    Board (Dec. 8, 2009, B208994) (nonpub. opn.). The issues were the propriety of (1) the
    Board‟s disallowance of $613,000 in attorney fees in calculating the Park‟s operating
    expenses; and (2) the Board‟s use of an amendment to the Guidelines that lowered the
    interest rate applied in calculating the amount needed to compensate the owner for capital
    improvements. The trial court granted the writ petitions solely with respect to an
    operating expense requiring an additional rent adjustment of $3.21 per space, and the
    Court of Appeal affirmed.
    6
    Neet was a member of the Appraisal Institute, a licensed appraiser and a licensed
    real estate broker.
    7
    The 9 percent expected return was allegedly based on data reported in the
    Investors Survey, 3rd Quarter 2007, which, according to Neet, indicated that “[f]or
    mobile home park acquisitions, the survey reports discount rate requirements in the range
    of 8.52% to 12.44%, with an average of 9.87%.” “Discount rate[]” is essentially an
    estimate of the expected return on capital and includes not only income, but the expected
    profit from the property‟s appreciation. Neet concluded that a base discount rate of 10.5
    percent would be appropriate and then deducted 1.5 percent to take into account expected
    appreciation, which he presumed would be low (half the rate of the estimated rise in the
    Department of Labor‟s Consumer Price Index (CPI)) due to the existence of the
    Ordinance regulating rents. In making his calculations, Neet assumed that interest rates
    would rise during the period the property was held.
    8
    To reach that conclusion, Neet used $2,031,941 for appellant‟s gross income,
    $1,727,103 for its operating expenses, and $1,309,236 for its debt service (reportedly
    derived from appellant‟s financial statement for April 2006 to March 2007).
    8
    invested in the Park and if it had, there would have been zero debt service. Neet
    agreed the criticism was well-taken and made no further reference to this analysis -
    - or to the $618 rent increase it allegedly supported -- in his supplemental reports.
    Prior to the hearing on its application, appellant withdrew the contention that a
    monthly rent increase of $618 was required under any proper analysis.
    b. Subsequent Calculations
    In connection with appellant‟s initial application, Neet conducted two
    additional analyses, which purported to justify lesser rent increases and which,
    with some adjustments, form the basis of appellant‟s current contentions
    concerning fair rent. Neet calculated, based on the same expected 9 percent return
    on the property‟s $23,050,000 million purchase price, that even excluding
    appellant‟s debt service, there would be a shortfall of $1.769 million, requiring an
    increase in rents of $365 per space per month.9 Neet also calculated that in order
    for appellant to receive a return of 11.5 percent ($580,750) per year on its actual
    equity (the $5.05 million down payment), rents would need to be raised $327 per
    space per month when debt service was taken into account.10 Neet called the
    9
    Neet concluded appellant‟s net operating income (gross income minus operating
    expenses) was $304,838, which, when deducted from the $2,074,500 “expected” 9
    percent return, left $1,769,662.
    10
    Neet contended that the Investors Survey, 3rd Quarter 2007 data indicated that
    equity dividend rates in the range of 8.42 to 17.23 percent were required or expected by
    mobilehome investors. The 11.5 percent rate chosen by Neet was based on his opinion
    that “[w]here a particular property falls in the quoted range is dependent primarily on the
    market[‟]s perception of risk and potential for growth in excess of predicted norms.”
    Acknowledging that rents in mobile home parks in Carson “increas[ed] at a rate slower
    than the rate of inflation (approximately 50% of the historic inflation rate),” Neet
    contended that this increased the “risk” of the investment and therefore should lead to a
    higher rate of return, which he initially calculated to be 14.5 percent and then adjusted
    due to the expected appreciation in the value of the property over time, which he assumed
    (Fn. continued on next page.)
    9
    former calculation a “Net Operating Income” analysis and the latter calculation a
    “Net Income to Equity” analysis.11
    After receiving the Board staff‟s initial analysis (discussed further below),
    which concluded that a significant portion of appellant‟s alleged operating
    expenses should be disallowed, Neet recalculated the rent increase required under
    his “Net Operating Income” analysis and concluded a lesser increase of $210 was
    warranted. Neet also recalculated the rent increase under his “Net Income to
    Equity” analysis and concluded an increase of $161.84 was warranted.12
    to be 3 percent of the purchase price or 8 to 9 percent of the “equity component” (the
    $5,050,000 down payment). This led to an “appropriately supported” 11.5 percent
    “equity dividend rate.”
    11
    In its brief, appellant uses the terms “return on value” for Neet‟s second
    calculation and “return on equity” for his third calculation. A true “return on value”
    analysis computes a return by comparing net operating income to the fair market value of
    the property. Courts have consistently rejected the contention that a rent control board
    must utilize a formula that calculates return based on fair market value. (See, e.g., Fisher
    v. City of Berkeley (1984) 
    37 Cal.4th 644
    , 680, fn. 33; Baker v. City of Santa Monica
    (1986) 
    181 Cal.App.3d 972
    , 979-980.) Because Neet began with the purchase price, his
    second calculation, as well as his third, are “„return on investment‟” analyses. Such an
    approach compares net operating income with either the owner‟s purchase price
    (sometime referred to as the “„historical cost‟”) or with the owner‟s actual equity
    investment in the property (the down payment plus any paydown of principal). (See
    Palomar Mobilehome Park Assn. v. Mobile Home Rent Review Com. (1993) 
    16 Cal.App.4th 481
    , 487-488 [discussing differences between return on value and return on
    investment approaches].) Only when return on investment is based on the owner‟s equity
    is the expense of debt service taken into consideration in calculating fair return. (Ibid.;
    Yee v. Mobilehome Park Rental Review Bd. (1993) 
    17 Cal.App.4th 1097
    , 1104, fn. 5
    [“The „historical cost‟ standard treats the actual cost of the property including that
    represented by encumbrances . . . as the „investment‟ and the net operating income with
    no deduction for interest paid on encumbering debt as the „return.‟ The „return on equity‟
    standard . . . treats equity cost rather than total cost as the „investment‟ and the net
    operating income after deduction of interest on encumbering debt as the „return.‟”]
    (Italics omitted.).)
    12
    Neet supplemented his report a few months later and concluded that due to
    inflation since the Park‟s purchase, the value of the $23,050,000 purchase price and
    (Fn. continued on next page.)
    10
    In May 2008, while the application was pending, appellant submitted an
    MNOI analysis by Michael St. John, Ph.D. For the base year, Dr. St. John used
    1978 -- the year prior to imposition of rent control -- and concluded a $208.22 per
    space per month rent increase was necessary to maintain that year‟s net operating
    income based on indexing the 1978 net operating income at 100 percent of the
    reported increase in the CPI since 1978.13
    2. Supplemental Rent Increase Application
    In September 2007, appellant also submitted a supplemental rent increase
    application, referred to as a “fair return” application.14 The supplemental
    appellant‟s $5,050,000 down payment had increased by 3.5 percent. Using these figures,
    Neet calculated that under the “Net Operating Income” analysis, an increase of $224.33
    was necessary, and under the “Net Income to Equity” analysis, an increase of $166.04
    was required. Later in the process, the Board staff realized that it had omitted increased
    property taxes from allowed expenses. Neet did not revise his calculations to factor in
    increased property taxes. In its brief, appellant contends that the final result using Neet‟s
    assumptions, but with property taxes included, would be $248.95 and $190.66,
    respectively.
    13
    Acknowledging the absence of any documentation of income and expense
    numbers from the prior owner, St. John stated that his figures for 1978 were “taken
    without adjustment from [the former owner‟s] 1980 rent increase application . . . .” St.
    John concluded that the base year‟s net operating income was $587,518. Applying the
    Department of Labor‟s determination that the CPI rose 231 percent between 1978 and
    2007, St. John calculated that maintenance of 1978‟s net operating income would require
    2007‟s net operating income to be $1.9 million. St. John‟s analysis was submitted after
    the Board staff had prepared its preliminary report indicating some alleged operating
    expenses reported by appellant should be disallowed. Based on figures for expenses
    adjusted downward by the Board staff, the Park‟s net operating income in 2007 was
    either just over or just under $1 million, depending on whether increased property taxes
    were taken into account. In making his final calculation, St. John took the increase into
    account.
    14
    Supplemental applications are governed by paragraphs IV.A.1 through 4 of the
    Guidelines, the provisions permitting the owner to rebut the presumption that application
    of the factors in the Ordinance leads to a fair return by presenting additional evidence,
    (Fn. continued on next page.)
    11
    application contained a Gross Profit Maintenance (GPM) analysis.15 The
    application stated that in order for appellant to maintain the 2005 (pre-purchase)
    gross profit, an increase of $388.85 per space per month was warranted.
    Essentially, it concluded appellant was entitled to approximately $800,000 in gross
    profits to match the prior owner‟s 2005 gross profits of $718,240, adjusted for
    inflation by 100 percent of the CPI. To reach that figure, an additional $1.88
    million in revenue was needed in view of appellant‟s much larger debt service.
    That figure, divided by 403 spaces and 12 months, equaled the requested $388.85
    increase.
    3. Board Experts’ Reports
    The Board hired its own expert, Kenneth Baar, Ph.D, who performed both a
    GPM analysis and an MNOI analysis. Under Dr. Baar‟s GPM analysis, which
    used 2005 as the base year, increase in rents would have been in the $200 range
    (the precise number dependent on the rate used for the increase in the CPI between
    2005 and 2007), and all but approximately $15 of it would be due to appellant‟s
    increased debt service. However, Dr. Baar expressed the opinion that use of a
    GPM approach to calculate fair rent would not be appropriate because the amount
    appellant paid for the Park “was not „reasonable in light of existing rents.‟” He
    including purchase date and price, net operating income of the park prior to the purchase,
    an appraisal of the park at the time of purchase, the amount of the down payment, and the
    rate of return of comparable mobilehome parks in jurisdictions with and without rent
    control. As it was prepared at the same time as the original application, the supplemental
    application used appellant‟s original expense numbers.
    15
    This analysis is similar to the MNOI analysis in that it uses a base year in which
    the return to the owner is assumed to be fair and then calculates adjustments to rent
    necessary to roughly maintain that same rate of return. A significant difference is that the
    GPM analysis calculates gross profits rather than net operating income, and thus requires
    subtracting debt service. (See Guidelines, §II(C)(2).)
    12
    also noted that “[i]n recent decades,” some real estate investors “have accepted a
    very low rate of return at the outset in return for the prospects of appreciation and
    some tax shelter benefits.” Dr. Baar expressed the opinion that appellant had paid
    an excessive price for the property and incurred negative cash flow based on its
    belief that it would automatically “obtain a substantial rent increase.”16 Dr. Baar
    stated that rate of return formulas which include debt service “suffer from the
    shortcoming that they are circular in the context of rent regulations. In the
    marketplace, investment is determined by the allowable returns. Therefore, it is
    circular to let the investment determine the allowable return. In effect, this
    approach allows the investor to set the allowable return by setting the investment.”
    Dr. Baar expressed the additional concern that if debt service were generally to be
    considered in determining rent increases, “debt service arrangements may be
    manipulated for the purpose of obtaining larger rent increases,” for example, by
    “refinanc[ing] at a lower interest rate or pay[ing] off [a] loan after the rent increase
    is granted.” Dr. Baar reviewed the Board‟s past actions in resolving rent
    adjustment applications and concluded: “[I]t has not been the standard practice of
    the Board to grant substantial rent increases based on increases in debt service.”
    Dr. Baar ultimately concluded that in determining the amount to increase
    rent for a new owner with higher debt service, an MNOI analysis was more
    appropriate than a GPM analysis: “The rationale for an MNOI approach is that
    regulated owners are permitted an equal rate of growth in [net operating income]
    regardless of their particular purchase and financing arrangements. Therefore,
    16
    An appraisal prepared by Rob Detling the year after the purchase had been
    attached to Neet‟s original report as an exhibit and was referred to by Neet to support his
    calculations. The appraisal stated: “There is a high probability that the rent control board
    will allow some, if not all, of the increased property taxes and mortgage interest
    occasioned by a March 30, 2006 sale to be passed through to the residents, increasing the
    rent level at the [Park] in the near term.”
    13
    rents are regulated depending on increases in expenses and the inflation rate
    ([CPI]).” It becomes the investor‟s task to determine what investment and
    financing arrangements make sense in light of the growth in net operating income
    permitted under the fair return standard.” Although specific financing and
    purchase arrangements were not considered, the growth in net operating income
    allowed some level of increasing debt service and finance costs over time.
    Furthermore, “because value is a function . . . of net operating income, indexing
    [net operating income] leads to appreciation in the value of a property, which may
    be converted into a capital gain. This approach meets the twin objectives of
    „protecting‟ the mobilehome owners from „excessive increases‟ and providing park
    owners with a „fair return on investment.‟”
    Dr. Baar conducted an MNOI analysis, using 2005 as the base year.17 Using
    the Park‟s 2005 net operating income of approximately $1.1 million, he calculated
    that to maintain that NOI after allowable adjustments, rents would need to be
    increased $8.61 if indexed at 50 percent of CPI, $12.12 if indexed at 75 percent of
    CPI and $15.65 if indexed at 100 percent of CPI.
    The City also retained James Brabant as an expert, primarily to analyze Neet‟s
    reports and calculations.18 Brabant pointed out discrepancies in Neet‟s
    calculations, including that Neet essentially used one figure for net operating
    17
    In a supplemental report, Dr. Baar explained the rationale for using 2005 rather
    than an earlier year as the base year: “After one individual park adjustment decision is
    made pursuant to the net operating income standard, the use of the original base year in
    the course of considering a subsequent application would constitute a „reconsideration‟ of
    the evidence that provided the basis for the earlier determination. Furthermore, it could
    result in a „de facto‟ modification of the prior decision in the sense the outcome of the
    new decision could be based on a different conclusion about what rent increases were
    reasonable since the [original] base year.”
    18
    Like Neet, Brabant was a member of the Appraisal Institute and a certified real
    estate appraiser.
    14
    income ($304,838) to justify his claim that a rent increase was needed, and
    another, much higher, figure ($1.1 million) to justify the purchase price paid by
    appellant. Brabant further criticized Neet‟s report for contending that 9 percent
    represented a reasonable rate of return, when the capitalization rate used to justify
    the sales price was 4.75 percent, and capitalization rates from six comparable sales
    ranged from 3.9 to 6.3 percent.19 In this regard, Brabant stated: “If you perform an
    analysis that uses one rate to justify a purchase price and then use a higher rate for
    the fair return analysis, a rent increase will always be indicated.” With respect to
    the 11.5 percent return used in Neet‟s “Net Income to Equity” analysis, Brabant
    stated that Neet failed to supply “any equity dividend rates extracted from sales of
    mobile home parks to support his use of an 11.5% rate,” and concluded that the
    Board could “give little weight to or choose not to have confidence in this aspect of
    the Neet analysis.”20 Finally, to the extent Neet attempted to justify the high
    returns he deemed appropriate based on the riskiness of the investment, Brabant
    concurred with an opinion expressed by Dr. Baar that “„after a park has been
    constructed and occupied with mobilehomes, there is virtually no rental risk,‟”
    stating that “[t]his conclusion has been supported and documented in countless
    studies and I have personally observed this phenomena in over 30 years of
    appraising mobile home parks.” As a result of the low risk level, “the discount
    19
    “[C]apitalization rate” is the ratio between a rental property‟s net operating
    income and its purchase price. Brabant obtained the capitalization rate figures for
    comparable sales from the Detling appraisal. Brabant found these figures for acceptable
    capitalization rates more credible than Neet‟s because Neet‟s analysis failed to include or
    consider capitalization rates from recent comparable sales.
    20
    Dr. Baar had also criticized this aspect of Neet‟s analysis: “In essence, . . . [Neet]
    contends that because there is rent regulation[,] the park owner must be permitted more
    rent than otherwise would yield a fair return in order to provide a higher rate of return
    than the prevailing rate.” Appellant continues to contend that an 11.5 percent rate is
    appropriate for a return on equity analysis.
    15
    rates for Mobile Home Park acquisitions are lower than the rates for apartments,
    office buildings, industrial properties and retail facilities . . . reflective, at least in
    part, of the lower risk of vacancy.”21
    4. Board Staff’s Analysis
    The Board‟s staff reviewed the applications and in February 2008 prepared a
    report. The report concluded appellant‟s operating expenses had been overstated
    and that the Park‟s current net operating income was over $1 million.22 Even
    taking debt service into account, there was a shortfall of less than $200,000. With
    respect to appellant‟s MNOI analysis and specifically its contention that the
    appropriate base year was 1978, the report stated: “As the Board is aware, each
    application has historically been reviewed and evaluated only for the period of
    time since the park‟s last public hearing. . . . In addition, the current revised
    guidelines for the implementation of the Ordinance specifically address this issue
    and preclude the Board from reconsidering past actions . . . .” With respect to the
    21
    The Detling appraisal stated: “The mobile home spaces at the subject property are
    currently 100% occupied. The comparables listed in the Market Overview section
    indicate an adjusted overall vacancy rate of 0.0% for stabilized parks in the subject‟s
    general area. Historically, once a mobile home park is fully occupied, occupancy
    remains relatively high. This is due to the high cost of moving a home, the stability of
    the resident base, and the significant investment residents sometimes make on
    landscaping and improvements on their individual spaces. When residents do leave the
    park, their homes are usually sold „in place,‟ with no lost rent accruing to the park
    owner.”
    22
    The staff report concluded that expenses for the 2006 to 2007 period were $2.198
    million, including $1.254 million for debt service. The alleged operating expenses
    disallowed primarily consisted of (1) attorney fees incurred as the result of appellant‟s
    attempt to convert the Park to condominium-style ownership, its attempt to add additional
    spaces to the Park, and its challenges to prior Board decisions; and (2) expenditures on
    capital improvements, which should have been (and subsequently were) the subject of a
    separate application for a temporary rent increase. Appellant does not challenge these
    conclusions and adjustments on appeal.
    16
    CPI increase used in appellant‟s MNOI analysis, the report stated: “[Appellant‟s]
    calculation utilizes . . . 100% of the CPI, when arguably a lesser amount such as
    75% and or 50% of the CPI increase may be adequate under the particular
    circumstances of a given application . . . .”
    The staff conducted its own GPM analysis. Using a slightly lower CPI,
    based more precisely on the date of the applications, the date of the last rent
    increase (2006), and the adjusted figures for operating expenses, the report stated
    that in order for appellant to obtain the same income as the prior owner, an
    increase of $200.93 per space per month would be required, almost all of it the
    result of appellant‟s increased debt service.23 The report advised that the GPM
    analysis was “merely a tool to aid the Board in making its decision.”
    The staff report noted that a rent increase had been approved in 2006 and
    stated that another option was simply to raise rents in the amount of the increase in
    CPI, or some fraction of the CPI since that time, which would have resulted in
    increases by amounts between $6.08 and $15.94. The report stated that the two
    comparable (rent-controlled) mobilehome parks in the City had average rents of
    $543.35 and $300.57, compared to the Park‟s then-average of $414.25.
    The staff recommended that the Board permit a rent increase of $15.65 in
    accordance with Dr. Baar‟s MNOI analysis using 100 percent of CPI.
    Subsequently, the staff realized that Dr. Baar had not taken into account the
    increase in property taxes caused by the transfer of the property from the previous
    owner to appellant. Including increased property taxes in its determination, the
    23
    The report also contained calculations based on using 75 percent and 50 percent of
    CPI instead of 100 percent, but as the base period was only a year prior to the application,
    the differences were slight -- $200.93 versus $198.56 or $196.23.
    17
    staff concluded that a higher increase was warranted: $33.23 if indexed at 50
    percent of CPI, $36.74 at 75 percent of CPI, or $40.27 at 100 percent of CPI.
    5. Hearing and Determination
    A hearing before the Board took place on June 11, 2008. Brabant testified
    and reiterated his view of the problems and discrepancies in Neet‟s report. He
    again explained that studies showed mobilehome park ownership was a low risk
    investment. He further explained that capitalization rate is a measure of the overall
    rate of return on a property based on a ratio of its net operating income to its
    purchase price, that Neet‟s calculations represented an attempt to arrive at an
    inflated capitalization rate to justify the rent increase appellant sought, and that
    based on comparable sales, 4.75 percent represented an appropriate capitalization
    rate for the Park. Brabant pointed out that the figures used in the Detling appraisal
    to justify the purchase price demonstrated that the property could not cover debt
    service in the amount incurred.
    Dr. Baar testified concerning the appropriate formula to use to calculate fair
    return. He expressed the view that the MNOI approach was preferable to other
    possible approaches because “it provides . . . the right to a steady growth of net
    operating income [that] is consistent with the purposes of the ordinance [--]
    protecting residents from unreasonable increases and allowing a fair return.” He
    stated that permitting increases in rent based on debt service would defeat rent
    control and noted that the amount of debt on a property could easily be
    manipulated. He testified that even using an MNOI base year of 1978, at a more
    appropriate rate of increase of 40 or 50 percent of CPI, the rent increase would be
    $75 or $102 when property taxes were credited, rather than the $208 Dr. St. John
    calculated.
    18
    Neet testified that the property was purchased on the open market at a price
    sufficient to beat other prospective purchasers, and that the loan was a typical one
    because appellant put 20 percent down and 80 percent was financed by a reputable
    third party lender. He reiterated his conclusion that a 9 percent return on value or a
    11.5 percent return on equity were reasonable discount rates based on reported
    surveys of expectations of real estate investors. He testified that investments such
    as government bonds and certificates of deposit were returning 4.5 to 5 percent at
    the time of his analysis.
    Detling testified that he appraised the Park based on comparisons with other
    similar properties, including 12 sales comparables.24 He had calculated the
    capitalization rate of 4.75 percent based on the sales price and the projected first
    year of net operating income, and concluded the rate of return was “relatively risk
    free” because the rents were below market and there was no real risk that they
    would decrease. He further testified that the terms of the loan and the interest rate
    were “within market parameters.”
    At the hearing, the Board approved a resolution granting a rent increase in
    the amount of $36.74 per space per month, a total of $177,675 per year.
    D. Appellant’s September 2008 (“Year 2”) Rent Increase Applications
    1. General Rent Increase Application
    On September 28, 2008, appellant submitted a new rent increase application
    to the Board. Neet again provided “Net Operating Income” and “Net Income to
    Equity” analyses. He claimed that in the preceding year, the Park‟s gross income
    was $2,053,692 and its operating expenses were $1,512,273, resulting in net
    operating income of $541,419. Using a 8.75 percent expected return on value, he
    24
    Detling included only the “six primary sales comparables” in the written appraisal.
    19
    contended an increase in the amount of $336.76 per space per month was
    warranted.25 Using the same $541,419 for net operating income and deducting
    $1,353,506 allegedly spent on debt service, he concluded the Park was losing
    $812,177 per year. Applying the 11.5 percent figure used to calculate expected
    return on equity for the prior year‟s application and an “inflation adjusted equity
    investment” of $6,800,000, he calculated the expected return was $782,000.
    Adding $782,000 to $812,177, he concluded the shortfall was $1,594,177,
    necessitating a rent increase of $329.65.
    2. Supplemental Rent Increase Application
    In September 2008, appellant also submitted a supplemental “fair return”
    application containing a GPM analysis. Based on income of $2,053,692, expenses
    of $2,865,869 (including debt service of approximately $1.3 million), and a target
    gross profit of $843,934, appellant claimed a shortfall of $1,656,111 and contended
    an increase of $342.46 per space was required to maintain the pre-purchase gross
    profit.
    3. Board Experts’ Reports
    The Board again retained the services of Dr. Baar and Brabant to respond to
    appellant‟s rent increase applications and Neet‟s analysis. Dr. Baar noted that “the
    25
    Neet first adjusted the purchase price of $23,050,000 upward to $24,800,000
    (7.5725 percent, reportedly to account for inflation), and then multiplied by 8.75 percent
    to obtain the required net operating income of $2,170,000. Neet reportedly derived the
    8.75 percent figure from the Investors Survey, 3rd Quarter 2008, which allegedly
    indicated that for mobile home park acquisitions, the expected discount rate was in the
    range of 7.52 percent to 11.77 percent. Opining that the risk factor required a discount
    rate near the upper end of the range, he concluded a rate of 10.25 percent would be
    appropriate. He reduced that figure by 1.5 percent, one-half of the expected annual CPI
    of 3 percent, to account for appreciation.
    20
    applicant‟s claim for a right to a rent increase is principally based on a claim of a
    right to cover the debt service increase since the purchase of the property and a
    claim to a right to an 8.75% rate of return on the purchase price. Each of these
    claims was addressed in the prior [rent application proceeding] . . . .” Dr. Baar
    again advocated in favor of the MNOI approach, because it “permitted an equal
    rate of growth in [net operating income] regardless of [the owner‟s] particular
    purchase and financing arraignments” and required the investor “to determine what
    investment and financing arrangements make sense in light of the growth in net
    operating income permitted under the fair return standard.”26 He described it as
    superior to other methods of calculating a fair return, such as GPM or return on
    investment, because it did not permit the park owner to “„regulate[]‟” rents by
    “setting the investment and/or the level of debt service.” Dr. Baar continued to
    criticize Neet‟s contention that “because there is rent regulation the park owner
    must be permitted more rent than otherwise would yield a fair return in order to
    provide a higher rate of return than the prevailing rate.”
    Brabant reiterated his criticisms of Neet‟s analysis, particularly in using the
    4.75 percent capitalization rate to justify the price paid for the property, but then
    claiming that a much higher rate was necessary to produce a fair return. He again
    observed that Neet‟s 9 percent return rate was not based on a direct comparison of
    capitalization rates from comparable mobile home parks in California, as was the
    4.75 percent rate set forth in the Detling appraisal. The Detling appraisal further
    established that when acquired by appellant, “the property . . . was not producing
    anything approaching the income necessary to cover [appellant‟s] debt service . . .
    and provide a positive cash flow . . . . In fact with a net income before debt service
    26
    Dr. Baar‟s MNOI calculation would have provided for an increase in Year 2 of
    between $23.06 and $26.97.
    21
    of $1,110,009 and debt service of $1,309,236 the equity dividend projected for the
    first year for the applicant‟s ownership was a negative $199,227.” Brabant
    reiterated that there was very little risk involved in owning a fully constructed and
    occupied mobilehome park.
    4. Board Staff’s Analysis
    Considering the factors set forth in the Ordinance, the Board‟s staff found
    that the CPI had increased 1.06 percent above the level considered at the time of
    the prior adjustment. The staff further found that rents at the Park continued to be
    midway between the averages charged at nearby parks. The staff recognized that
    there had been capital improvements, including some improperly included as
    operating expenses, but recouping those expenses required a separate application
    for a temporary rent increase. The staff also recognized that property taxes and
    utility expenses had increased slightly. It found that overall expenses had risen by
    $192,029, primarily due to an increase in the variable rate on the Park‟s
    mortgage.27
    The staff performed a GPM analysis, using the prior year as the base year,
    which supported a rent increase of $39.71 per space per month due to the increase
    in operating expenses and debt service. It also performed an MNOI analysis,
    which supported an increase of $25.02 based on the increase in operating expenses
    and 75 percent of CPI. The staff recommended an increase in accordance with the
    MNOI analysis, which would raise rents at the Park to an average of $476.01 per
    space per month.
    27
    As it had the prior year, the staff concluded that a number of items had been
    improperly included in the operating expense category. It concluded that appellant‟s
    expenses, including debt service of $1,353,596, totaled $2,509,263.
    22
    5. Hearing and Determination
    The hearing on appellant‟s second rent increase applications took place on
    June 10, 2009. Dr. Baar testified that the issues raised in the 2008 rent increase
    applications were the same as those raised in the prior year when the Board
    concluded that the debt service was not reasonable in light of the existing rents.
    He explained that rates of return had been on the decline since the 1990‟s and the
    early 2000‟s and that current rates of return on rental properties were six percent
    on average, subject to a great deal of variance. He expressed the opinion that a
    realistic rate of return analysis must take into account the appreciation that was
    likely to occur. A member of the Board‟s staff pointed out that within days of
    purchasing the Park, appellant sent out notices announcing plans to convert the
    Park to condominium-style ownership, indicating that appellant paid a premium
    price for the Park and was expecting a temporary loss which would be made up
    when the spaces were sold.
    Neet testified that according to surveys, the rate of return expected by real
    estate investors was commensurate with the numbers in his report and analysis.
    Detling testified that his post-purchase appraisal was justified by offers received
    from other parties and recent sales of six other mobilehome parks in California,
    three of which were rent-controlled and three of which were not.
    At the conclusion of the hearing, the Board approved an increase in the
    amount of $25.02 per space per month.
    E. Federal Court Action
    After the Board‟s action on the 2007 applications, appellant filed suit against
    respondents in federal court, asserting facial and as-applied takings claims and
    facial and as-applied due process claims. It also sought a writ of administrative
    mandate under state law. The district court found that the facial takings and due
    23
    process claims were time barred because the Ordinance had been enacted in 1979,
    and that the 2006 amendments to the Guidelines did not revive the claims, as they
    did not amend the Ordinance. The court further found that the Guidelines “d[id]
    not significantly alter the effect of the Ordinance on [appellant]” because “[t]he
    Ordinance permits the Board to use any formula it chooses that meets the purposes
    of the Ordinance, whether or not the formula was mentioned in the Guidelines.”
    The district court found the as-applied takings claim unripe because
    appellant had never sought compensation under California law as required by
    Williamson County Regional Planning Commission v. Hamilton Bank of Johnson
    City (1985) 
    473 U.S. 172
     (Williamson).28 Finally, the court concluded that
    appellant had failed to state an as-applied substantive due process claim because
    there was no fundamental constitutional right to raise rents, and the Board‟s actions
    did not amount to egregious or shocking official conduct lacking a legitimate
    government interest. Accordingly, by order dated November 24, 2009, the court
    dismissed appellant‟s facial takings claim, facial due process claim, and as-applied
    due process claim with prejudice, and dismissed the as-applied takings claim
    without prejudice. The court then dismissed appellant‟s state law claim seeking a
    writ of administrative mandate, first concluding it had supplemental jurisdiction
    over the pendant claim, but then declining to assert it on the ground that there was
    significant potential for inconsistent rulings because appellant would be seeking
    28
    In Williamson, the Supreme Court held that to bring a takings claim in federal
    court based on state action, a plaintiff must satisfy a two-prong test. “First, a plaintiff
    must demonstrate that „the government entity charged with implementing the regulations
    has reached a final decision regarding the application of the regulations to the property at
    issue.‟ [Citation.] Second, the plaintiff must have sought, and been denied,
    „compensation through the procedures the State has provided for doing so.‟” (Colony
    Cove Props. LLC v. City of Carson (9th Cir. 2011) 
    640 F.3d 948
    , 958, quoting
    Williamson, 
    supra, at pp. 186, 194-195
    .)
    24
    the same relief in state court when it pursued its as-applied takings claim under
    state law.
    While the instant appeal was pending, the Ninth Circuit affirmed the district
    court‟s rulings in a published opinion: Colony Cove Props. LLC v. City of Carson,
    
    supra,
     
    640 F.3d 948
    . The circuit agreed that appellant‟s facial takings claim was
    untimely, that the 2006 amendments to the Guidelines did not alter the 1979
    Ordinance, and that appellant‟s as-applied takings claim was unripe. (Id. at
    pp. 957-959.)29 The court further found the factual allegations of the complaint
    insufficient to support appellant‟s as-applied due process claim that the Board‟s
    decision was arbitrary, irrational, and lacking any reasonable justification in the
    service of a legitimate government interest. (Id. at pp. 961-962.)
    F. Proceedings Below
    On December 23, 2009, appellant filed a petition for writ of administrative
    mandate seeking review of the Board‟s 2008 determination of its September 2007
    rent increase applications. On February 3, 2010, appellant filed a second petition
    for writ of administrative mandate seeking review of the Board‟s 2009
    determination of its September 2008 rent increase applications. Both petitions
    contended that the pertinent rent increase determination was arbitrary, unsupported
    by evidence, and grossly insufficient to provide appellant with a fair return.
    Specifically, the petitions contended (1) use of the MNOI approach was unfair
    because it was first discussed in the Guidelines after appellant purchased the Park;
    (2) the only proper base year for an MNOI analysis was one prior to institution of
    rent control; (3) the full rate of inflation according to the CPI should have been
    29
    In the appeal to the Ninth Circuit, appellant did not challenge the dismissal of its
    facial due process claim. (See Colony Cove, 
    supra,
     640 F.3d at p. 954, fn. 2.)
    25
    used in calculating fair rent, and there was no rational basis for the Board‟s
    decision to base the increase on 75 percent of CPI; and (4) the Board failed to
    properly consider appellant‟s fair return application. The first petition contended
    that a minimum rent increase of $200 was necessary for appellant to earn a fair
    return in Year 1. The second petition contended that the minimum necessary rent
    increase in Year 2 was $250.
    Appellant‟s petitions included a section entitled “Reservation of Federal
    Claims,” which stated: “Under England [v. Medical Examiners (1964) 
    375 U.S. 411
     (England)] and its progeny, [appellant] hereby reserves any and all federal
    claims arising from the facts alleged herein for litigation in federal court and gives
    notice to all parties and the Court that any resolution of state-law issues herein
    shall not constitute a binding resolution of parallel or related federal issues and
    shall have no claim or issue preclusion for [appellant‟s] federal claims.
    [Citation.]” After the first petition was filed, respondents moved to strike the
    reservation of federal claims. Respondents argued that the reservation was
    improper, because “an England reservation can only be asserted where there is a
    pending federal action in which the federal court has exercised . . . abstention
    [under Railroad Commission of Texas v. Pullman Co. (1941) 
    312 U.S. 496
    (Pullman)]. [Appellant] has not alleged (because it cannot) that there is such a
    pending federal action (nor is there, in fact, any pending federal action). [¶]
    [Appellant] did file a federal district court complaint on October 27, 2008, which
    arose from the same facts as this Petition, but the district court dismissed all of
    [appellant‟s] claims in that action on November 24, 2009, on grounds other than
    Pullman abstention, and did not retain jurisdiction. There is no pending federal
    action in which the federal court has exercised Pullman abstention.” (Italics
    omitted.)
    26
    The court granted the motion to strike. After appellant filed the second
    petition, the parties entered into a stipulation and order, subsequently approved by
    the court, that the England reservation in that petition would be stricken, and that
    the stipulation and order would have the same impact on appellant‟s appellate and
    federal court rights as if the court had entered an order striking the reservation after
    a full contested hearing on the merits.
    Following a hearing, on June 30, 2010 the court denied the first petition on
    the basis of “three established legal principles that govern this type of case”: “1.
    There is no single constitutionally required formula which must be used when
    government seeks to regulate the price charged for a good or service. A
    governmental entity may choose to regulate pursuant to any fairly constructed
    formula even though other proper formulas might allow for higher prices. [¶] 2.
    There is a range of rents which can be charged, all of which could be characterized
    as allowing a just and reasonable return. [¶] 3. The MNOI . . . approach has been
    praised by commentators for both its fairness and ease of administration. The
    board is not obliged to reject an MNOI analysis just because a historical formula,
    using the actual cost of acquisition would yield a higher rent increase. [Citation.]
    [¶] Under the foregoing principles, the landlord cannot insist that a fair return must
    be calculated on the basis of what it paid for the mobile home park, instead of an
    MNOI analysis. Nor can the landlord insist that an MNOI analysis must use a pre-
    rent control base year. The selection of a base year because it was a year in which
    the then owner of the mobile home park received a rent increase which it did not
    challenge as unfair, is a rational basis for selecting the base year, and the landlord
    cannot insist upon another base year, equally reasonable, just because it yields a
    higher rent increase. [¶] . . . It is the governmental entity that administers the rent
    control ordinance that gets to choose among proper formulas and use an approach
    27
    that both protects the tenants from excessive rent increases and allows a fair return
    on investment to the landlord.”
    The parties entered into a stipulation and order, subsequently approved by
    the court, that the decision and judgment entered on the first petition (Year 1)
    would be adopted as the decision and judgment in the second petition (Year 2)
    “and will have the same impact on [appellant‟s] appellate and federal court rights
    as if [] the Court had entered an order denying the [petition]. The court thereafter
    entered a judgment denying the second petition “[f]or the reasons set forth in the
    Court‟s Minute Order [in the proceedings on the first petition] on June 30, 2010 . .
    . .” Appellant separately appealed the judgments entered on the petitions. The
    appeals were consolidated.
    DISCUSSION
    It has long been established that local rent control ordinances are
    constitutional “exercises of governmental authority” and “„“not per se takings.”
    [Citation.]‟” (Santa Monica Beach, Ltd. v. Superior Court (1999) 
    19 Cal.4th 952
    ,
    962, quoting Pennell v. City of San Jose (1988) 
    485 U.S. 1
    , 12, fn. 6; see
    Birkenfeld v. City of Berkeley (1976) 
    17 Cal.3d 129
    , 158-159.) Rent control
    regulations are permissible if they are “reasonably calculated to eliminate
    excessive rents and at the same time provide landlords with a just and reasonable
    return on their property.” (Birkenfeld v. City of Berkeley, supra, at p. 165.) In the
    context of price control, which includes rent control, a regulation that “deprive[s]
    investors of a „fair return‟” becomes “„confiscatory‟” and violates due process as
    well as the takings clauses of the state and federal Constitutions. (Kavanau, 
    supra,
    16 Cal.4th at p. 771.)
    Appellant contends that the rent increases approved by the Board using its
    MNOI analysis required it to operate the Park at a loss, resulting in the application
    28
    of the City‟s rent control Ordinance in a confiscatory and unconstitutional manner.
    Specifically, appellant maintains that the Board was obliged to apply a formula that
    ensured gross profits and a positive cash flow, taking its debt service into account.
    Alternatively, appellant contends the Board erred in using 2005 as the base year for
    its MNOI analysis and applying an inflation adjustment component equal to 75
    percent of the CPI. For the reasons discussed, we disagree.
    A. Standard of Review
    An aggrieved landlord who believes that the rent allowed by a rent control
    board or agency does not provide a fair return “may seek judicial review of an
    administrative rent control decision by filing a petition for a writ of mandate in the
    Superior Court. [Citations.] „The inquiry in such a case shall extend to the
    questions whether the respondent [agency] has proceeded without, or in excess of
    jurisdiction; whether there was a fair trial; and whether there was any prejudicial
    abuse of discretion. Abuse of discretion is established if the [agency] has not
    proceeded in the manner required by law, the order or decision is not supported by
    the findings, or the findings are not supported by the evidence.‟” (MHC Operating
    Limited Partnership v. City of San Jose (2003) 
    106 Cal.App.4th 204
    , 216, quoting
    Code Civ. Proc., § 1094.5, subd. (b).)
    Appellate review of the factual basis behind a decision by a rent control
    board or agency is governed by the substantial evidence standard. (MHC
    Operating Limited Partnership v. City of San Jose, supra, 106 Cal.App.4th at
    p. 217; Carson Harbor Village, Ltd. v. City of Carson Mobilehome Park Rental
    Review Bd. (1999) 
    70 Cal.App.4th 281
    , 287.) In applying the standard, we focus
    on the decision of the agency rather than that of the trial court and “„answer the
    same key question as the trial court . . . whether the agency‟s findings were based
    on substantial evidence. [Citations.]‟” (MHC Operating Limited Partnership v.
    29
    City of San Jose, supra, 106 Cal.App.4th at pp. 218-219.) “[W]e consider all
    relevant evidence in the administrative record, beginning with the presumption that
    the record contains evidence to sustain [the agency‟s] findings of fact.” (TG
    Oceanside, L.P. v. City of Oceanside (2007) 
    156 Cal.App.4th 1355
    , 1371.) Our
    goal is to determine whether substantial evidence supports the agency‟s finding
    that the rents were set at a level sufficient to provide the owner a non-confiscatory,
    fair return. “[I]n the absence of an unconstitutional and confiscatory taking, the
    courts [are] not authorized to interfere with the actions of the local rent boards
    . . . .” (City of Berkeley v. City of Berkeley Rent Stabilization Bd. (1994) 
    27 Cal.App.4th 951
    , 959.)
    To the extent the administrative determination rests on the agency‟s
    interpretation or application of an ordinance, it presents a question of law which
    we review independently. (MHC Operating Limited Partnership v. City of San
    Jose, supra, 106 Cal.App.4th at p. 219.) However, a rent control board‟s
    interpretation of a rent control ordinance and its implementing guidelines is
    entitled to considerable deference. (Id. at pp. 219-220; Carson Harbor Village,
    Ltd. v. City of Carson Mobilehome Park Rental Review Bd., 
    supra,
     70 Cal.App.4th
    at p. 287.) “The burden is on the appellant to prove the board‟s decision is neither
    reasonable nor lawful.” (70 Cal.App.4th at p. 287.)
    B. 2007 Rent Increase Applications (Year 1)
    1. Use of MNOI Analysis to Establish Fair Rent
    To avoid becoming unconstitutionally confiscatory, a rent control regulation
    system must be applied so as to provide investors a “„fair return.‟” (Kavanau,
    
    supra,
     16 Cal.4th at p. 771; Galland v. City of Clovis (2001) 
    24 Cal.4th 1003
    , 1021
    (Galland).) “The term „fair return‟ is incapable of precise definition . . . .”
    (Donohue v. Santa Paula West Mobile Home Park (1996) 
    47 Cal.App.4th 1168
    ,
    30
    1177.) It is said that it must be high enough “to encourage good management,
    reward efficiency, discourage the flight of capital, and enable operators to maintain
    their credit.” (Cole v. City of Oakland Residential Rent Arbitration Bd. (1992) 
    3 Cal.App.4th 693
    ; accord, Oceanside Mobilehome Park Owners’ Assn. v. City of
    Oceanside (1984) 
    157 Cal.App.3d 887
    , 907; see Kavanau, 
    supra,
     16 Cal.4th at
    p. 772.) It has also been said that a valid price control scheme must permit an
    efficiently run company to earn a return commensurate with returns on investments
    having corresponding risks. (Fisher v. City of Berkeley, supra, 37 Cal.3d at p. 683;
    Donohue v. Santa Paula West Mobile Home Park, supra, at p. 1177.) On the other
    hand, a fair return must not be “„so high as to defeat the purposes of rent control
    nor permit landlords to demand of tenants more than the fair value of the property
    and services which are provided.‟” (Oceanside Mobilehome Park Owners’ Assn.
    v. City of Oceanside, supra, 157 Cal.App.3d at p. 907.) “Thus, „[the] rate of return
    permitted may not be as high as prevailed in the industry prior to regulation nor as
    much as the investor might obtain by placing his capital elsewhere.” (Ibid.) As
    our Supreme Court explained in Galland, 
    24 Cal.4th 1003
    , “comparison of the rate
    of return of rent-controlled mobilehome parks with those of non-rent-controlled
    parks . . . is of limited utility in establishing the constitutional minimum rate of
    return” because “it is obviously not the case that a rent-controlled investment must
    earn the same as a non-rent-controlled one.” (24 Cal.4th at pp. 1026-1027.)
    Moreover, “„“[s]ome lessening of appreciation is a necessary consequence of any
    rent control, since future appreciation is to a significant extent a function of
    increased rental income. [Citation.] It is one of the very sources of long-term
    appreciation -- inflated rents -- that rent control measures are intended to restrict.”
    [Citation.]‟” (Id. at p. 1026.)
    The Supreme Court has held that rent control ordinances may incorporate
    “any of a variety of formulas” for calculating rent increases and satisfy the fair
    31
    return standard. (Kavanau, supra, 16 Cal.4th at p. 761.) In Fisher v. City of
    Berkeley, supra, 37 Cal.3d at pp. 679-680, the Court cited authorities advocating a
    number of different approaches and stated: “[R]ent control agencies throughout
    this state and the nation have employed a veritable smorgasbord of administrative
    standards by which to determine rent ceilings. [Citations.] As we recently stressed
    . . . , „rent control agencies are not obliged by either the state or federal
    Constitution to fix rents by application of any particular method or formula.‟
    [Citations.] [¶] . . . [S]election of an administrative standard by which to set rent
    ceilings is a task for local government . . . not the courts.” (37 Cal.3d at pp. 679-
    681, quoting Carson Mobilehome Park Owners’ Assn. v. City of Carson (1983) 
    35 Cal.3d 184
    , 191.)30 Determining whether a particular rent control determination or
    scheme is confiscatory depends on “the overall result of the rent-setting process,
    not the method employed or any particular exemption legislated . . . .” (Galland,
    
    supra,
     24 Cal.4th at p. 1028.)
    A rent control board, in deciding which formula to apply, has no obligation
    to choose the one that would provide the owner the highest rate of return.
    (Rainbow Disposal Co. v. Escondido Mobilehome Rent Review Bd. (1998) 
    64 Cal.App.4th 1159
    , 1172.) “[T]he term „fair rate of return‟ . . . refers to a
    constitutional minimum within a broad zone of reasonableness.” (Galland, 
    supra,
    30
    In Carson Mobilehome Park Owners’ Assn. v City of Carson, the Supreme Court
    upheld the underlying Ordinance against a facial challenge brought by a group of
    mobilehome park owners who contended that the Ordinance was unconstitutional
    because it advocated no specific formula and, therefore, “fail[ed] to provide sufficient
    standards to guide the Board in acting on applications . . . .” (Carson Mobilehome Park
    Owners’ Assn. v City of Carson, 
    supra,
     35 Cal.3d at pp. 190-191.) The court held the
    fact that the Ordinance “does not articulate a formula for determining just what
    constitutes a just and reasonable return does not make it unconstitutional.” (Id. at p. 191.)
    By stating that rent increases would be granted upon a determination that they are “„just,
    fair and reasonable‟” and specifying an illustrative list of relevant facts the Board was to
    consider, the Ordinance provided sufficient guidance. (Id. at pp. 190-191.)
    32
    24 Cal.4th at p. 1026.) “[A] governmental entity may choose to regulate pursuant
    to any fairly constructed formula even though other proper formulas might allow
    for higher prices.” (Palomar Mobilehome Park Assn. v. Mobile Home Rent Review
    Com., supra, 16 Cal.App.4th at p. 487.) “Regulations that enable the company to
    operate successfully cannot be condemned as invalid, even though they might
    produce only a meager return.” (TG Oceanside, L.P. v. City of Oceanside, supra,
    156 Cal.App.4th at p. 1373.) “For those price-regulated investments that fall
    above the constitutional minimum, but are nonetheless disappointing to investor
    expectations, the solution is not constitutional litigation but, as with nonregulated
    investments, the liquidation of the investments and the transfer of capital to more
    lucrative enterprises.” (Galland, supra, at p. 1026.) The goal is to set rents at the
    point at which “an efficient enterprise” can operate successfully. (Id. at p. 1021.)
    Courts have approved a number of approaches taken by rent control boards
    to calculate fair return. (See, e.g., Cotati Alliance for Better Housing v. City of
    Cotati (1983) 
    148 Cal.App.3d 280
    , 286-288 [approving return on investment
    approach, where “investment” was defined as initial cash outlay plus payments
    toward principal and value of any subsequent improvements]; 31 Palos Verdes
    Shores Mobile Estates, Ltd. v. City of Los Angeles (1983) 
    142 Cal.App.3d 362
    , 371
    31
    Appellant cites Cotati for the proposition that the minimum standard for fair rent
    is “that amount which will permit the property to generate income sufficient to cover the
    costs of operation and the servicing of reasonable financing and to ensure the return of a
    reasonable profit.” (Cotati Alliance for Better Housing v. City of Cotati, supra, 148
    Cal.App.3d at p. 294.) The formula at issue in Cotati contained a return on investment
    component, with investment defined as initial cash outlay plus any payments made
    toward principal. (Id. at pp. 286-287.) That approach to calculating fair return may
    require consideration of the expense of debt servicing. (Ibid.; see also Yee v. Mobilehome
    Park Rental Review Bd., 
    supra,
     17 Cal.App.4th at pp. 1106-1107 [agency improperly
    failed to consider mortgage interest payments required by return on equity formula it
    adopted].) We do not read the court‟s statement as intended to apply where other
    approaches are taken to calculating fair return.
    33
    [upholding a “„maintenance of profit‟” approach enabling the landlord to maintain
    same net profit as obtained in the last unregulated year].) The MNOI formulation
    used by the Board has been approved by multiple courts where, as here, it includes
    an inflation adjustment component and where the regulations contain a mechanism
    for adjustments to account for capital improvements. (See, e.g., TG Oceanside,
    L.P. v. City of Oceanside, supra, 156 Cal.App.4th at pp. 1371-1372; Donohue v.
    Santa Paula West Mobile Home Park, supra, 47 Cal.App.4th at pp. 1177-1178;
    Oceanside Mobilehome Park Owners’ Assn. v. City of Oceanside, supra, 157
    Cal.App.3d at p. 902; Rainbow Disposal Co. v. Escondido Mobilehome Rent
    Review Bd., 
    supra,
     64 Cal.App.4th at p. 1172.)
    The MNOI approach does not focus on how much the owner chose to pay
    for a rent-controlled property or how the purchase was financed. That fact does
    not render it constitutionally invalid. In Donohue v. Santa Paula West Mobile
    Home Park, where the rent control ordinance permitted adjustments to “„maintain
    net operating income‟” and specifically excluded from consideration “„[m]ortgage
    principal [and] interest payments,‟” the court rejected the owner‟s facial challenge
    to the ordinance: “Numerous courts . . . have acknowledged that the [MNOI]
    approach is constitutionally valid,” even though it ignores “certain expenses
    incurred by the landlords” in determining NOI, including “land acquisition costs
    . . . . ” (Donohue v. Santa Paula West Mobile Home Park, supra, 47 Cal.App.4th
    at p. 1178; see Rainbow Disposal Co. v. Escondido Mobilehome Rent Review Bd.,
    
    supra,
     64 Cal.App.4th at p. 1172 [rent board need not reject MNOI merely because
    formula using owner‟s actual cost of acquisition yielded higher rent increase].)
    Indeed, the MNOI standard has been praised by courts and commentators for
    “its fairness and ease of administration” (Palomar Mobilehome Park Assn. v.
    Mobile Home Rent Review Com., supra, 16 Cal.App.4th at p. 486), because it
    “„recognizes that in the rental housing market, ratios of rental income to value,
    34
    equity, and gross income vary substantially among buildings. Therefore, rather
    than designating a particular rate of return as fair, [MNOI] standards pursue the
    best available option, which is to preserve prior [net operating income] levels.”
    (H.N. & Frances C. Berger Foundation v. City of Escondido (2005) 
    127 Cal.App.4th 1
    , 9.) The advantage of the MNOI approach over other methods of
    determining fair rent was further explained in Oceanside Mobilehome Park
    Owners’ Assn. v. City of Oceanside, where the court stated: “„Use of a return on
    value standard would thoroughly undermine rent control, since the use of
    uncontrolled income potential to determine value would result in the same rents as
    . . . would be charged in the absence of regulation. Value (and hence rents) would
    increase in a never-ending spiral.‟” (Oceanside Mobilehome Park Owners’ Assn.
    v. City of Oceanside, supra, 157 Cal.App.3d at pp. 899-900, quoting Cotati
    Alliance for Better Housing v. City of Cotati, supra, 148 Cal.App.3d at p. 287.) A
    return on investment standard may also be problematic to administer, because an
    owner‟s equity can be greatly affected by individual differences in methods and
    costs of financing, and because owners who inherit rental property or receive it
    through a gift have no cash investment against which to measure their return.
    (Cotati Alliance for Better Housing v. City of Cotati, supra, at p. 289.) Use of the
    MNOI formula “„“avoids the necessity of having to undertake the administratively
    difficult (if not impossible) task of calculating equity and/or fair market value.”‟”
    (Oceanside Mobilehome Park Owners’ Assn. v. City of Oceanside, supra, 157
    Cal.App.3d at p. 903.) Instead, it “permits park owners to obtain a just and
    reasonable return under general marketing conditions in any given year” and
    “reflect[s] the tenant‟s interest by giving the park owner an incentive to incur all
    reasonable expenses for maintenance and services.” (Id. at pp. 902-903.)
    Appellant does not dispute that the MNOI approach has been upheld by
    every court to have considered it. Nor does it dispute that the Supreme Court has
    35
    upheld an agency‟s use of any fairly constructed formula. Appellant insists,
    however, that whatever formula is used, the owner must be permitted to pass its
    costs on to renters, without regard to the method of financing or the amount of the
    resulting rent increase. It cites Westwinds Mobile Home Park v. Mobilehome Park
    Rental Review Bd. (1994) 
    30 Cal.App.4th 84
     (Westwinds) for the proposition that
    the existence of annual losses after all expenses, including debt service, are taken
    into account constitutes proof that the return is unfair. No such holding can be
    found in that case. The $4 rent increase approved there using an historical cost
    approach had resulted in a 2.78 percent return to the owner, representing the ratio
    between the purchase price and net operating income, without considering the cost
    of debt service. (Id. at pp. 91-92.) But “absolutely no evidence” was presented
    that comparable investments produced returns of 2.78 percent. The court held that
    without such evidence, the 2.78 percent return could not be presumed to be fair.
    (Id. at p. 92.) The court alluded to debt service, noting that the owner was losing
    approximately $10,000 per year after paying interest on its purchase loan; but far
    from concluding that this was definitive proof that rents were too low, the court
    explained that it had “rejected the notion that permissible rental rates . . . can vary
    depending solely on the fortuity of how the acquisition was financed.” (Id. at
    pp. 91, 93-94.)32
    32
    In support of this proposition, the court cited its decision in Palomar Mobilehome
    Park Assn. v. Mobile Home Rent Review Com., where the agency had compared net
    operating income to the owner‟s historical cost less depreciation to determine an
    appropriate rate of return on the owner‟s two parks. The owner complained that this
    formula failed to take into account interest expenses on the debt incurred to purchase its
    parks. (Palomar Mobilehome Park Assn. v. Mobile Home Rent Review Com., supra, 16
    Cal.App.4th at p. 488.) The court explained that consideration of debt service would
    result in unfair variance in rents depending on the owner‟s individual financing
    arrangements: “Assume two identical parks both purchased at the same time for $1
    million each. Park A is purchased for cash; Park B is heavily financed. . . . [C]alculating
    (Fn. continued on next page.)
    36
    Apart from the inequities that would result from permitting a party who
    financed its purchase of rent-controlled property to obtain higher rents than a party
    who paid all cash, there are additional reasons for disregarding debt service. As
    explained by Dr. Baar, debt service arrangements could easily be manipulated for
    the purpose of obtaining larger rent increases, by applying for an increase based on
    servicing a high interest loan and then refinancing at a lower interest rate or paying
    off the loan after the increase was granted. Alternatively, an owner might
    periodically tap the equity in a valuable piece of rental property, thus increasing
    the debt load. In any event, we discern no rational basis for tying rents to the
    vagaries of individual owners‟ financing arrangements.
    Appellant claims that the City did not properly perform a fair rent analysis,
    and that “unrebutted evidence” established that the rent increase permitted by the
    Board did not result in a fair rate of return, even if debt service is disregarded.
    Appellant refers specifically to the testimony and reports of its expert John Neet
    who purportedly “analyzed rates of return on directly comparable investments --
    other mobilehome parks -- and determined that the proper rate[] of return [is] 9.0%
    for a return on [purchase price/historical cost] analysis . . . .” Neet‟s analysis was
    contradicted by Detling‟s appraisal, as explained by the reports and testimony of
    Brabant. In the appraisal, Detling compared the sales prices and net operating
    income of six similar mobilehome parks to determine those parks‟ capitalization
    return based on total historic cost and treating interest payments as typical business
    expenses would mean that Park A would show a considerably higher operating income
    than Park B . . . [and] the owners of Park B would be entitled to charge higher rents than
    the owners of Park A. We see no reason why this should be the case.” (Ibid.) The
    decisions in Westwinds and Palomar predated the widespread adoption of the MNOI
    approach by cities and rent control agencies. Their holdings are nonetheless pertinent to
    the present case because they establish that a legally sufficient rent increase formula need
    not take debt service into account.
    37
    rates and found that capitalization rates from comparable parks varied from 3.9
    percent to 6.3 percent. Detling further calculated that based on the $23 million
    purchase price and the Park‟s 2005 net operating income of $1.1 million, the Park
    had a capitalization rate of 4.75 percent at the time of the sale.33 According to
    Brabant, Detling‟s analysis of comparable sales established that 4.75 percent was
    an acceptable rate of return for an investment in a mobilehome park. Brabant
    further explained that mobilehome parks were a low risk investment justifying a
    relatively low return due to the likelihood that the spaces would be rented at or
    near 100 percent capacity. On this evidence, the Board could reasonably conclude
    that maintaining the Park‟s net operating income would result in a fair return to
    appellant. At the time of the Year 1 rent increase, the staff calculated that the
    Park‟s net operating income had been reduced to $944,029 due to a legitimate
    increase in operating expenses. By increasing rental income by $177,675 per year,
    the Board returned the operation to the same financial footing it was on at the time
    of the purchase.
    In any event, it was appellant‟s burden to establish to the Board‟s
    satisfaction that the rent increase of $36.74 proposed by Dr. Baar and the staff
    using the MNOI analysis would not provide a fair return (see Guidelines, §IV(A)).
    It failed to do so. As explained by Brabant‟s reports and testimony, Detling‟s
    appraisal established that a rent increase of $36.74 would maintain the Park‟s
    MNOI and capitalization rate within the range acceptable to the average investor.
    Detling‟s figures for average capitalization rates were supported by the sales of at
    least six comparable mobilehome parks. Neet‟s analysis represented an attempt to
    33
    As capitalization rate measures the ratio of the purchase price to net operating
    income, this essentially meant that had appellant purchased the Park with cash and
    incurred no substantial increase in operating expenses, it would have obtained that 4.75
    percent return annually on its $23 million investment.
    38
    manufacture a required rate of return using questionable assumptions and
    unsupported numbers. He began with an investor survey which indicated higher
    returns (8.52 to 12.44 percent) were necessary because it included a component for
    anticipated appreciation and was not limited to rent controlled parks. (See Los
    Altos El Granada Investors v. City of Capitola (2006) 
    139 Cal.App.4th 629
    , 640
    [comparing rates of return that include appreciation with capitalization rates was
    “like comparing apples and oranges”].) Neet then opined that the acceptable rate
    of return for the Park should be toward the high end of that spectrum based on his
    curious conclusion that a rent controlled mobilehome park should be expected to
    return more than a non-rent controlled one. As our Supreme Court has said, the
    opposite should be expected to occur. (Galland, supra, 24 Cal.4th at pp. 1026-
    1027.) Then, rather than deduct the Park‟s historical appreciation rate (which had
    been quite high) or an appreciation rate based on appellant‟s proposed use of the
    property, he estimated a modest 1.5 percent appreciation rate going forward.34 As
    Brabant explained, the end result of Neet‟s calculations was a figure for a rate of
    return that represented a ratio between the Park‟s net operating income and its
    purchase price -- in other words, its capitalization rate. But the Board had no
    reason to rely on Neet‟s contorted analysis when it had before it evidence, based on
    actual sales, showing that a capitalization rate of 4.75 percent was acceptable to
    investors and about average for comparable mobilehome parks. The Board
    approved an increase in rent which kept the Park‟s ratio of net operating income to
    purchase price at about the same level as at the time of purchase, providing a return
    34
    Even at that rate, the Park would appreciate at the rate of $345,750 per year. We
    note that when calculating the rent increase needed for a “fair” return in support of
    appellant‟s Year 2 applications, Neet estimated the value of appellant‟s investment in the
    Park at $24,800,000, an increase of $1,750,000, based on a 7.5725 percent rate of
    inflation.
    39
    similar to that of other comparable parks. The Neet analysis provides no basis to
    overturn the Board‟s determination.
    The parties debate whether appellant overpaid for the Park. Appellant relies
    on evidence that the purchase was an arms-length transaction, and that other
    potential buyers made similar offers. The City relies on the fact that the amount
    paid was in excess of the amount that could be justified by the Park‟s rental income
    if the purchase required assumption of an 80 percent loan at 7 percent interest. We
    do not consider this issue determinative. The MNOI approach used by the Board is
    an approved methodology that does not take land acquisition cost, including debt
    service, into account. By maintaining net operating income, adjusted upward for
    inflation, from year to year, this approach allows for appreciation and permits the
    purchaser to determine whether the property is worth the selling price based on the
    purchaser‟s individual cash flow requirements and its future plans for the property.
    Although the Board did not consider appellant‟s long-term plans when it addressed
    the rent increase applications, we note that the City has approved appellant‟s
    application to convert the Park to condominium-style ownership, allowing
    appellant to sell the plots individually to the mobilehome owners. Accordingly,
    appellant cannot reasonably be heard to complain that it has been forced by the
    Board‟s decision to operate a losing investment.35
    35
    (See Palomar Mobilehome Park Assn. v. Mobile Home Rent Review Com., supra,
    16 Cal.App.4th at p. 489 [“„Return‟ on a piece of investment property should include
    both short-term return, in the form of rents, and long-term return, which is reflected by
    the appreciated value of the property realizable only when the property is sold.”].) Using
    the staff‟s numbers for gross income and expenses -- which appellant does not dispute for
    purposes of this appeal -- the total cash deficit including debt service was just over
    $300,000 after the property tax increase was included. The $36.74 rent increase
    permitted by the Board increased the Park‟s income by $177,675 per year, leaving a
    small deficit, acknowledged by appellant to be $134,297. A deficit of $134,297 would be
    more than compensated for by even a modest amount of appreciation.
    40
    2. Use of 2005 for Base Year
    Appellant contends the use of 2005 as the base year for the MNOI analysis
    was inappropriate, and that a proper MNOI analysis must always begin with a year
    prior to the institution of rent control. Alternatively, it contends that the City failed
    to permit appellant, as a new property owner, to rebut the presumption that the
    previous owner was earning a fair return. Finally, it contends that the evidence
    presented “more than rebutted that presumption.” For the reasons discussed, we
    find no merit to these contentions.
    The Guidelines provide an “assumption” that the profit earned by the park
    owner when the Ordinance was adopted provided a fair return. (Guidelines,
    §§I(C); IV(A).) The original park owner had the right to rebut the assumption and
    apply for an increase on the ground that existing rents did not allow the owner to
    earn a fair return. (Id., §I(E).) Thereafter, the Board was to evaluate rent increase
    applications on the basis of changes in income, expenses, CPI, etc. that occurred
    after the date of the last increase approved by the Board. (Ibid.) The Guidelines
    expressly prohibit the Board from reconsidering its past decisions on rent
    adjustments “after they have been embodied in a formal written resolution setting
    forth the findings of the Board.” (Ibid.) In accordance with the Guidelines, the
    Board here assumed that the Park‟s net operating income at the time of the last rent
    increase obtained by the prior owner allowed a fair return and used 2005 -- the year
    before appellant purchased the Park -- as the base year for its MNOI calculation.
    The Board concluded that to do otherwise would essentially constitute
    reconsideration of its past decisions, which had become final through the passage
    of time or court challenges.
    As appellant acknowledges, “[c]ourts have approved the selection of base
    years that significantly postdate the enactment of rent control.” (Los Altos El
    Granada Investors v. City of Capitola, supra, 139 Cal.App.4th at p. 655; see, e.g.,
    41
    MHC Operating Limited Partnership v. City of San Jose, supra, 106 Cal.App.4th
    at p. 223, fn. 4; Rainbow Disposal Co. v. Escondido Mobilehome Rent Review Bd.,
    
    supra,
     64 Cal.App.4th at p. 1170.) It is within a city‟s prerogative and legislative
    authority “to determine what rent control scheme it will adopt” and “to decide what
    base year to employ in its rent control ordinance.” (MHC Operating Limited
    Partnership v. City of San Jose, supra, at p. 223 & fn. 4.)
    Appellant cites Palomar Mobilehome Park Assn. v. Mobile Home Rent
    Review Com., supra, 
    16 Cal.App.4th 481
    , contending the court there disallowed
    use of an MNOI analysis because it did not begin with a pre-rent control base year.
    Appellant‟s interpretation of Palomar is incorrect. The ordinance at issue did not
    adopt an MNOI approach. (Id. at p. 485.) However, in evaluating whether the
    rental income received by the owner met the ordinance‟s “„fair return on
    investment‟” standard, the city attempted to rely on a calculation showing that the
    owner‟s NOI had not decreased. (Id. at pp. 486, 488.) The court held that because
    the ordinance did not establish a pre-rent control base year or provide procedures
    for the owner to contest whether it had received a fair return in the applicable base
    year, the city could not justify its decision on that basis. (Id. at p. 486.) Here, the
    Ordinance and Guidelines expressly permitted the former owner of the Park to
    present evidence that the pre-rent control rents did not allow it to earn a fair return.
    Accordingly, the MNOI analysis undertaken by the Board did not violate any
    principle set forth in Palomar.
    Appellant further contends that use of an MNOI analysis is not appropriate
    unless the current owner is afforded the opportunity to challenge whether the
    previous owner‟s net operating income represented a fair return, and that it
    received no such opportunity here. The Guidelines specifically state that “each
    park owner has the right to apply for an increase on the ground that existing rents
    do not allow the park owner to earn a fair return,” directing applicants to the
    42
    procedures for submitting a supplemental fair return application. (Guidelines,
    §I(F).) In discussing the fair return application procedures, the Guidelines reiterate
    that the Ordinance is based on the assumption that the rents in effect before the
    adoption of the Ordinance provided a fair return, and that the park owners
    attempted to rebut that presumption when the first applications for rent increases
    were submitted. However, the Guidelines further provide that the current owner
    “may file [a fair rent] application based on the claim that a rent increase is
    necessary because the park cannot earn a fair return without an increase greater
    than that permitted by application of the factors in the Ordinance . . . .” (Id.,
    ¶IV.A.) In connection with this application the applicant may submit any
    “evidence [it] consider[s] relevant.” (Id., ¶IV.A.4.) Appellant submitted a
    supplemental fair rent application, and nothing in the record indicates it was
    restricted in its ability to present evidence, including evidence that the former
    owner was not receiving a fair return.
    With respect to its contention that the evidence undisputedly established that
    the 2005 net operating income was insufficient to provide the former owner a fair
    return, appellant points to evidence indicating that rents grew by 9 percent over a
    period when the inflation rate was 32.5 percent and that the former owner had
    failed to adequately maintain the property. There is no legal authority for the
    proposition that rent growth must match the rate of inflation to be considered fair.
    With respect to the prior owner‟s alleged maintenance shortcomings, appellant‟s
    increased maintenance expenses were accounted for in the MNOI analysis
    undertaken by the Board, and the cost of its capital improvements was the subject
    of a separate rent increase that permitted appellant to recover those costs. (See
    Oceanside Mobilehome Park Owners’ Assn. v. City of Oceanside, supra, 157
    Cal.App.3d at pp. 903 & 905 [MNOI approach “give[s] the park owner an
    incentive to incur all reasonable expenses for maintenance and services” because
    43
    park owners receive, through increases in NOI, a “„pass through‟ of the increase in
    operating costs”].)
    Moreover, appellant overlooks the overwhelming evidence that far from
    being disadvantaged by the imposition of rent control, the prior owner obtained a
    rate of return any investor would envy. It is undisputed that in the year prior to the
    sale to appellant, the former owner earned over $1.1 million in net operating
    income and had a gross profit of over $700,000.36 Nothing in the record indicates
    this was atypical or that returns were substantially less in the preceding years. In
    addition, based on the final sales price, the property was appreciating at an average
    rate of $1.7 million per year, all of which inured to the former owner‟s financial
    benefit when the property was sold. By any measure, this was a very healthy
    return on the $3.5 million initial investment. On the record before it, the Board
    was not required to look all the way back to 1978 to find a time when a Park owner
    was receiving a fair return. The Board‟s determination that 2005 was an
    appropriate year on which to base its MNOI analysis was reasonable.
    3. Indexing CPI at 75 Percent
    Amicus Pacific Legal Foundation contends that once a base year is selected
    for the MNOI analysis and net operating income for that year calculated, it must be
    adjusted upward for inflation by 100 percent of the CPI.37 The Supreme Court has
    36
    We note that these were the figures that according to Detling, justified the
    purchase price appellant paid for the Park. In Los Altos El Granada Investors v. City of
    Capitola, the court approved the use of 1987 as the base year in part because “that was
    the year Parkowner purchased [the park] and presumably adjusted its purchase price to
    provide it with a fair return based on the rent levels in effect at the time.” (Los Altos El
    Granada Investors v. City of Capitola, supra, 139 Cal.App.4th at p. 655.)
    37
    Appellant argues that the Board‟s decision to utilize 75 percent of CPI was
    arbitrary.
    44
    made clear that a valid rent control system “must generally permit profits to be
    adjusted over time for inflation so that the real value of that profit does not shrink
    toward the vanishing point.” (Galland, 
    supra,
     24 Cal.4th at p. 1026.) However,
    the contention that net operating profits must be adjusted by 100 percent of
    inflation has been repeatedly rejected. (See, e.g., Stardust Mobile Estates, LLC v.
    City of San Buenaventura (2007) 
    147 Cal.App.4th 1170
    , 1182 [upholding
    adjustment in the amount of 50 percent of CPI]; Oceanside Mobilehome Park
    Owners’ Assn. v City of Oceanside, supra, 157 Cal.App.3d at p. 902 [rent adjusted
    to ensure net operating income increased by percentage equal to lesser of housing
    component of CPI or 40 percent].) In H.N. & Frances C. Berger Foundation v.
    City of Escondido, the court explained why 100 percent indexing was not required
    for a rent controlled mobilehome park to achieve a fair return: “A mobilehome
    park‟s operating expenses do not necessarily increase from year to year at the rate
    of inflation, and . . . a „general increase at 100% of CPI . . . would be too much if
    expenses have increased at a lower rate.‟” (H.N. & Frances C. Berger Foundation
    v. City of Escondido, supra, 127 Cal.App.4th at p. 14.) Moreover, “the use of
    indexing ratios may satisfy the fair return criterion because park owners typically
    derive a return on their investment not only from income the park produces, but
    also from an increase in the property‟s value or equity over time.” (Ibid.; accord,
    Los Altos El Granada Investors v. City of Capitola, supra, 139 Cal.App.4th at
    p. 640 [explaining that “one reason for indexing NOI at less than 100 percent of
    the change in the CPI” is that “real estate is often a leveraged investment” in which
    “[t]he investor invests a small amount of cash, but gets appreciation on 100 percent
    of the value”].) Here, the Board took account of appellant‟s increased operating
    expenses and reasonably concluded a rent increase indexed at 75 percent of CPI
    would maintain net operating profits at the level necessary to provide a fair return.
    
    45 C. 2008
     Rent Increase Applications (Year 2)
    Appellant contends that the judgment in the writ proceeding involving the
    2008 rent increase applications should be reversed for the same reasons expressed
    in its argument and analysis pertaining to the 2007 rent increase applications. We
    have concluded that the substantial evidence supported the Board‟s conclusion that
    the rent increases allowed in connection with the 2007 applications were fair and
    non-confiscatory. We reach the same conclusion with respect to the rent increases
    allowed for the following year and likewise find no basis for reversing the trial
    court‟s order denying the petition. In brief, the staff‟s analysis of the 2008 rent
    increase applications showed net income of $2,053,692 for the fiscal year ending
    March 31, 2008, and operating expenses of $1,155,667, resulting in net operating
    income of $898,025.38 The approved rent increase of $25.02 per space per month
    increased net operating income by $120,996 to $1,019,021, maintaining
    approximately the same net operating income and capitalization rate as when the
    property was purchased.
    D. Grant of Motion to Strike England Reservation
    Appellant contends the trial court erred in striking its reservation of federal
    claims under England, supra, 
    375 U.S. 411
    . We agree.
    In England, the Supreme Court held that a litigant who has properly invoked
    the jurisdiction of a federal court cannot be compelled to accept a state court‟s
    determination of his or her federal claims. (England, 
    supra,
     375 U.S. at p. 415.) A
    party who must litigate certain issues in state court prior to pursuing related federal
    claims may “forestall any conclusion that he has elected not to return to the District
    38
    We note that the stated income would not have included any part of the prior rent
    increase, which was not approved until later in 2008.
    46
    Court . . . by making on the state record [a] „reservation to the disposition of the
    entire case by the state courts‟ . . . . That is, he may inform the state courts . . . that
    he intends, should the state courts hold against him on the question of state law, to
    return to the District Court for disposition of his federal contentions.” (Id. at
    p. 421.)
    Under California law, a party may move to strike “irrelevant, false, or
    improper matter inserted in any pleading.” (Civ. Proc. Code, § 436, subd. (a).) In
    striking the England reservation, the trial court acted in accordance with the
    decision in Los Altos El Granada Investor v. City of Capitola, supra, 
    139 Cal.App.4th 629
     (Los Altos I). There, the court upheld a similar order, finding that
    England endorsed inserting a reservation in a state court pleading only when the
    litigant had filed in federal court and the district court had abstained under
    Pullman, 
    supra,
     
    312 U.S. 496
    , that is, when there were “unsettled questions of
    state law which, when resolved, would obviate the need for a decision on the
    federal constitutional questions presented . . . .” (Los Altos I, supra, at p. 652.) In
    the case before the Los Altos I court, the district court had abstained under Younger
    v. Harris (1971) 
    401 U.S. 37
     (Younger), which requires abstention “if the state
    proceedings are (1) ongoing, (2) implicate important state interests, and (3) provide
    the plaintiff an adequate opportunity to litigate federal claims. [Citation.]‟” (Los
    Altos I, supra, at p. 653, quoting The San Remo Hotel v. City and County of San
    Francisco (9th Cir. 1998) 
    145 F.3d 1095
    , 1103.) The Los Altos I court concluded
    that “„England, and its reservations, are not relevant . . . in the Younger context,
    where the purpose of abstention is not clarification of state law, but reluctance to
    interfere with an ongoing state judicial proceeding.‟” (Los Altos I, 
    supra, at p. 654
    ,
    quoting Duty Free Shop v. Administracion De Terrenos (1st Cir. 1989) 
    889 F.2d 1181
    , 1183.)
    47
    That portion of the decision in Los Altos I has been undermined by a
    subsequent federal decision, Los Altos El Granada Investors v. City of Capitola
    (9th Cir. 2009) 
    583 F.3d 674
     (Los Altos II). Los Altos II, a continuation of the Los
    Altos I litigation in federal court, clarified that the plaintiff had submitted two
    England reservations. The first was included in a state court pleading after a
    district court had dismissed the plaintiff‟s takings claim as unripe under
    Williamson, 
    supra,
     
    473 U.S. 172
    ; the second occurred after a judgment upholding
    the agency‟s fair rent calculation was entered, at which point the plaintiff returned
    to federal court and the district court abstained under Younger, 
    supra,
     
    401 U.S. 37
    ,
    staying the federal case until the state appeal was resolved. The Ninth Circuit held
    that a reservation of claims under England was appropriate in both situations: (1)
    where the federal case is dismissed for lack of ripeness under Williamson, 
    supra,
    473 U.S. 172
    , and there is no federal case pending; and (2) where the district court
    abstains under Younger and does not dismiss, but stays the proceedings pending
    the final decision of the state courts.39 (583 F.3d at pp. 684-690.)
    The Ninth Circuit further held that a state court‟s decision to strike an
    England reservation will have no impact on the plaintiff‟s ability to pursue a
    federal claim after the state court litigation is concluded: “Even granting full faith
    and credit to the Superior Court‟s decision to delete [the plaintiff‟s] England
    reservation from its complaint, the Superior Court‟s action cannot have had any
    „preclusive‟ effect on the claims [the plaintiff] can assert before a federal court,”
    39
    The Ninth Circuit had previously held that an England reservation was appropriate
    where the litigant filed in state court first, due to a clear procedural obstacle, such as an
    exhaustion requirement, or where the plaintiff realized that abstention was likely.
    (United Parcel Service v. California Pub. Utilities (9th Cir. 1996) 
    77 F.3d 1178
    , 1182-
    1185; Tovar v. Billmeyer (9th Cir. 1979) 
    609 F.2d 1291
    , 1293-1294.)
    48
    because “an explicit, on the record reservation is not required to preserve federal
    claims.” (Los Altos II, supra, 583 F.3d at p. 687.)40
    Appellant‟s federal takings claim based on the Board‟s 2008 determination
    of the 2007 rent increase applications was dismissed by the district court for lack
    of ripeness under Williamson. Having received a clear message from the district
    court, appellant did not file a claim in federal court following the next year‟s Board
    determination. When appellant thereafter filed the superior court actions, it
    included the England reservations in order to advise the court and respondents that
    it had no intention of resolving its federal constitutional claims in state court, but
    would resort to federal court for resolution of such claims when the matters were
    ripe. Although the Ninth Circuit has held that insertion of an England reservation
    in a state court pleading is not a strict prerequisite to preserving federal claims, we
    conclude that it is neither “irrelevant, false or improper” for purposes of a motion
    to strike. The presence of the England reservation clarifies in a manner helpful to
    both the court and the opposing party that a litigant wishes to limit the state court
    action to state issues. On the other hand, striking a reservation may lead to
    unnecessary confusion and duplication, as the litigant may feel compelled to raise
    40
    The court based this assertion on the Supreme Court‟s statement in England that
    “„an explicit reservation is not indispensable; the litigant is in no event to be denied his
    right to return to the District Court unless it clearly appears that he voluntarily . . . and
    fully litigated his federal claims in the state courts.‟” (Los Altos II, supra, 583 F.3d at
    p. 688, quoting England, 
    supra,
     375 U.S. at p. 421.) Indeed, in the Ninth Circuit‟s view,
    the state court‟s decision to strike the England reservation helped preserve the district
    court‟s jurisdiction to hear the federal claims because it “demonstrat[ed] that „[the
    plaintiff was] compelled by the state courts to litigate [its federal] claims there‟” and that
    it had not “voluntarily litigated its federal claims in either the [local] Superior Court or
    the California Court of Appeal.” (583 F.3d at p. 688; see United Parcel Service v.
    California Pub. Utilities, supra, 77 F.3d at p. 1184 [“A free and unreserved submission to
    the state court of all federal claims for complete and final resolution [bars] return to the
    federal court.”].)
    49
    federal issues in the state action although he or she intends to litigate the matters in
    federal court. Moreover, to allow a motion to strike to succeed in this situation
    would only lead to pointless law and motion practice, as a state court order striking
    the reservation cannot curb a federal court‟s jurisdiction for the reasons stated in
    Los Altos II. Accordingly, we conclude that the better practice is to permit
    assertion of England reservations where the litigant‟s federal claims have been
    dismissed for lack of ripeness under Williamson, or where the litigant anticipates
    such dismissal and files first in state court.
    DISPOSITION
    The orders striking the England reservations from the petitions for writ of
    administrative mandate are reversed. In all other respects, the judgments are
    affirmed. The City is awarded its costs on appeal.
