    Plaintiffs and Appellants,

    v.
    COUNTY OF HUMBOLDT,                        (Humboldt County
    Super. Ct. No. DR170699)
    Defendant and Respondent.
    Appellants Tim and Kathy Phillips sought a reduction in the value at
    which property they purchased at a trustee’s sale was assessed, then
    challenged the value determined by the Assessment Appeals Board (Board)
    in superior court. They appeal from the judgment against them, arguing the
    Board improperly failed to apply the statutory presumption that the
    purchase price established the property’s value, conducted a flawed
    comparable sales analysis, and made various other errors. We affirm.
    Pursuant to California Rules of Court, rules 8.1105(b) and 8.1110, this
    *
    opinion is certified for publication with the exception of parts II. and III.
    1
    BACKGROUND
    On June 26, 2013, appellants purchased real property in Humboldt
    County at a public trustee sale for $153.806.41. The trustee’s deed, was
    recorded on July 12, 2013.1
    The property consists of two 80-acre parcels (parcel 101-122-006 & 101-
    131-001), which appellant2 testified had been merged in May 2000, and which
    were treated as one appraisal unit by the Humboldt County Assessor
    (Assessor). The terrain is mostly steep and wooded.
    As described by the appraiser, there is a 1,508 square foot, three-
    bedroom, two-bathroom, manufactured home on a permanent foundation on
    parcel 101-131-001, which uses a solar generator system for power, a spring-
    fed water system, and septic system. There are also several outbuildings and
    sheds that are in poor condition and do not add to the overall value of the
    property.
    According to appellant’s testimony, the property had been purchased in
    May 2000 for $125,000, and the owner added the modular home in 2001 at a
    cost of $85,000. The prior owners tried without success to sell all or a portion
    of the property in 2005, 2006, and 2009, and the mortgage holder foreclosed
    in 2012. The property is approximately two miles from a public road. When
    the prior owners left the property, they took the gas-powered generator,
    which was the only source of power; PG&E is two miles away. The prior
    owners had drilled two wells that failed to produce water and “had been
    hauling domestic water for years.” Mice had ruined the central heat ducting
    under the house and the private road had been neglected for years. As
    1The trustee’s deed shows the unpaid debt, together with costs, was
    $245,179.10.
    2   References to appellant in the singular are to Tim Phillis.

    appellant noted, the appraiser stated the property was in “poor” condition.
    After purchasing the property, appellant found a water source and installed a
    solar pump to pump water for the house, as well as an operating solar
    system.
    On November 26, 2013, appellants submitted an application for
    changed assessment (application No. 13-26); they filed an additional
    application (application No. 14-68) on November 10, 2014, and two more
    (application Nos. 14-72 & 14-73) on November 12, 2014.3 The enrolled
    property value challenged in application Nos. 13-26, 14-72, and 14-73 was
    $469,976, which was the prior owner’s assessment.4 In November 2014, the
    Assessor reappraised the property at $415,000, using a comparable sales
    analysis, and this was the value challenged in application No. 14-68. The
    Assessor explained that this appraisal was the result of a “2013 Prop 8”
    conducted as an “interim” measure because appellants had purchased the
    3 Application Nos. 13-26, 14-72, and 14-73 erroneously list the enrolled
    property value as $476,697 (application Nos. 13-26 and 14-72) and $472,140
    (application No. 14-73). As shown on the property tax bills, the $476,697
    figure omits the $7,000 homeowner exemption that resulted in the $469,976
    enrolled value. The figures on application No. 14-73 appear to result from
    mathematical and/or clerical errors: This application erroneously lists
    $372,494 as the land value rather than $370,811 (as shown on the property
    tax bills and application Nos. 13-26 and 14-72), lists $106,464 as the value of
    the improvements rather than the correct $106,165, and shows a total value
    of $472,140 while the correct total of the figures listed would be $479,140
    (372,494 plus 106,646 equals 479,140).
    4A note in the “Transaction Record” for the property states, “Valued
    both properties at $415,000, due to disagreement in value and app for appeal,
    revalued for 2013 and 2014 Prop B. 2013 value set at $415,000, and 2014
    value remains at $415,000.00. To place on 2013 Prop 8, value for land had to
    be adjusted. The preceding note, dated July 21, 2014, stated, “Spoke
    w/owner, property purchased in auction. Property was in poor condition.
    Owner will appeal anything over purchase price. Sold w/#101-131-001.”
    3
    property and were responsible for the outstanding taxes but “could not appeal
    the base year for 2013,” and a value had not yet been set for the date of
    acquisition. . . .
    Appellants’ applications were initially heard by the Board on March 12,
    2015. Relying upon the presumption stated in Revenue and Taxation Code5
    section 110, subdivision (b), that the purchase price of real property is
    rebuttably presumed to be its “full cash value” or “fair market value” “if the
    terms of the transaction were negotiated at arms length between a
    knowledgeable transferor and transferee neither of which could take
    advantage of the exigencies of the other,” appellant argued at the hearing
    that the price he paid for the property had to be treated as its taxable value
    unless respondent County of Humboldt could prove the foreclosure sale at
    which it was purchased was not an open market, arms length transaction.6
    The Assessor took the position that a foreclosure sale is not an open
    market transaction. The appraiser testified that although the trustee’s sale
    is public, potential purchasers at a public trustee sale in the county are
    limited by the requirements that a deposit of $2,500 be submitted prior to the
    auction and a winning bid must be paid within three days after the auction,
    so “traditional financing” is not available. The Assessor’s office pointed to an
    annotation from the California State Board of Equalization (SBE) stating
    that “[t]he presumptions of full cash value under Revenue and Taxation Code
    section 110 do not apply to execution and/or foreclosure sales, since these are
    Further statutory references will be to the Revenue and Taxation
    5
    Code unless otherwise specified.
    6   Appellant testified that no other bids were made at the auction.
    4
    forced sales and thus considered non-market transactions.”7 (Board of
    Equalization, Property Taxes Law Guide (Revision 2017), Annotation No.
    460.0031 (Mar. 26, 1999)
     [as of Dec. 31, 2020].)
    Appellant also challenged the Assessor’s comparable sales analysis,
    which was summarized on a spreadsheet comparing various aspects of
    appellants’ property with seven others, referred to as “Comp 1” through
    “Comp 5,” “711 Sawdust trail,” and “Off Centerville Rd.” Appellant argued
    the properties used as comparisons were “vastly different in size” and a
    “considerable distance” from the subject property; unlike his property, all but
    one of the comparison properties had PG&E service and all had water; the
    climate differed between the properties; and the subject property was in
    “substantially worse condition” than the others. In addition, appellant stated
    the Assessor’s office had “no calculations to arrive at the lot size value
    adjustment.”8
    7 The Board of Equalization annotations are published summaries
    prompted by requests for legal opinions, “brief statements—often only a
    sentence or two—purporting to state definitively the tax consequences of
    specific hypothetical business transactions. More extensive analyses, called
    ‘back-ups,’ are available to those who request them.” (Yamaha Corp. of
    America v. State Bd. of Equalization (1998) 
    19 Cal.4th 1
    , 4–5 (Yamaha).)
    8 Appellant asserted that one property on a July 2014 list was
    comparable to his, a 152-acre lot that sold for $130,000 in July 2013, and that
    this and a second property on the same list, a 160-acre lot that sold for
    $250,000 in October 2012, were “closest in size and location and amenities” to
    his property. This was not the list of comparable properties in fact used to
    establish the value of appellants’ property. The appraiser testified that the
    spreadsheet appellant was referring to was “the first attempt at finding
    comparables which was a failed attempt.” After further research, and after
    giving the list to appellant as part of an “open dialog” regarding the
    5
    In response to questions from the Board, appellant testified that his
    property was about two miles off a public road; the appraiser testified that
    while some of the comparable properties were closer to public roads, he did
    not feel this required adjustment because the properties were “drastically
    further” from cities and towns than the distance from appellants’ property to
    Ferndale. Asked about adjustments for the absence of public utilities on the
    property, the appraiser testified that he was not aware there was a problem
    with water or power and had been told “it was on solar” and had well water.
    He testified that if he had known, “I don’t know that it would make that big
    of a difference. A lot of these rural properties have issues with power and
    water.” Acknowledging appellant’s statement that the comparables did not
    have a problem with power, the appraiser said the information he had did not
    indicate one way or the other.
    After Board members expressed agreement with the Assessor’s view
    that a foreclosure sale is not an open market transaction, the matter was
    continued to allow the parties to attempt to reach a mutually acceptable
    determination of value in light of this view, and for the appraiser to address
    issues of concern to the Board regarding the comparables, including the
    properties’ access to utilities and distance from a public road.
    At the continued hearing in July 2015, appellant continued to rely upon
    the purchase price presumption as the measure of value, and argued the SBE
    annotation addressed tax sales rather than foreclosure sales. The appraiser
    Assessor’s process, the appraiser found the properties on this sheet were not
    comparable sales because each was “a direct from seller” sale that did not
    meet market standards or a gift, and one had different zoning (“TMZ” or
    Timberland Production Zone) than appellant’s property. None of the four
    properties on this list were among the comparables used by the Assessor to
    arrive at the $415,000 valuation.
    6
    provided information on whether each of the comparables had utility services
    and the distance of each from a public road. Appellant again argued the
    properties were not sufficiently similar to comply with the governing rules,
    while the appraiser explained that it was difficult to find comparable
    properties because the subject property is “unique” and these were “the best
    comps we could find,” “rural properties with a manufactured home on it.”
    The Board concluded that a foreclosure sale is not a fair market value
    sale and determined the value of the property to be $250,000, finding the
    comparable sales provided by the Assessor’s office “of marginal help due to
    condition, location, topography and parcel size.”
    Appellants filed a tax refund action in superior court in November
    2015, which was resolved by a stipulation for remand to the Board for
    determination of the value of the property based on evidence in the
    administrative record of the March 12 and July 20, 2015 proceedings. The
    stipulation and order vacating the Board’s 2015 decision, remanding the
    matter for a new hearing, decision and findings of fact, and dismissing the
    superior court action, was filed on March 8, 2017. Prior to the hearing on
    remand, appellants objected to the participation of one member of the Board.
    After a hearing, the request for disqualification was denied.
    At the June 8, 2017 hearing on remand, appellant again maintained
    the purchase price was the proper measure of value of the property, argued
    the comparative sales analysis could not be utilized unless the Assessor
    proved the foreclosure sale was not an open market transaction, and argued
    the properties the Assessor used as comparables were too dissimilar for this
    purpose. The Assessor reiterated the position that the foreclosure sale was
    not a market transaction, again pointing to Annotation No. 460.0031. The
    Assessor also noted the discussion of open market transactions in the
    7
    Assessment Appeals Manual, which states that that “ ‘[o]pen market
    conditions which tend to produce a ‘full cash value’ or ‘fair market value’ as
    defined in section 110 include: [¶] Exposure on the open market for a
    sufficient amount of time [¶] Neither the buyer nor the seller is able to take
    advantage of the exigencies of the other [¶] Both parties are seeking to
    maximize their gains [¶] Both buyer and seller have full knowledge of the
    property and are acting prudently.” (SBE, Assessment Appeals Manual (May
    2003) pp. 88–89.) Appellant asked the Board to remove the annotation from
    the record, arguing the Assessor violated statutory exchange of information
    rules by failing to provide it in response to appellants’ request for evidence
    that the foreclosure sale was not an open market transaction.
    The Board issued its ruling on August 3, 2017, finding the fair market
    value of the property on July 12, 2013, was $335,000. The Board disagreed
    with both the Assessor’s determination of $415,000 as the fair market value
    of the property and appellant’s position that the fair market value was
    $153,806.41. Its written findings state that a foreclosure sale “is generally
    not considered an open market transaction for purposes of determining fair
    market value,” citing the SBE letter underlying Annotation No. 460.0031,
    and, with respect to appellant’s objection, stating the document was
    considered as legal authority offered by the Assessor rather than as factual
    evidence. The Board also found that even if foreclosure sales could be
    considered open market in some circumstances, the sale in this case did not
    meet the required parameters in that it required potential bidders to pay a
    cash deposit and pay the total amount in cash within three days, thus
    excluding purchasers using traditional financing; the seller was forced to sell
    and not necessarily a “ ‘willing’ seller at the auction price”; the sale lacked
    “the exposure typical to real estate marketing”; and the buyer was in “at least
    8
    the potential position” of being able to take advantage of the owner’s
    necessity to sell. The Board found the comparable sales evidence was “of
    sufficient weight to establish that the $153,806.41 paid by the Applicant was
    below the fair market value of the Subject Property on the date of transfer.”
    Noting that appellant claimed the property was not habitable due to lack of
    power and water, that the comparables were habitable properties and that
    appellant had restored water to the property at a cost of about $7,000, the
    Board found the condition of appellants’ property was “generally of lower
    quality” than the comparables and assigned $15,000 to $20,000 as a
    “reasonable range of value for that difference in condition.” Disagreeing with
    the Assessor’s value and adjustments for the difference in size between
    appellants’ parcel and the comparison properties, the Board found “an
    amount of approximately $500 per acre to be a more reasonable value” for
    purposes of adjustment for size.9 The Board applied its adjustments,
    excluding the “high value and low value of comparable properties 1-5 plus
    Sawdust Trail,” resulting in an “approximate average” of $336,200 for the
    comparable properties, and concluded “a reasonable fair market value” for
    appellants’ property on the date of transfer was $335,000.
    On November 17, 2017, appellants filed a second lawsuit, alleging
    causes of action for property tax refund, federal and state due process
    violations, violations of title 42, United States Code section 1983, and
    declaratory relief. The trial court granted respondent’s motion for summary
    adjudication of the second through fifth causes of action, which were based on
    9The amount of the appraiser’s lot size adjustment for each comparison
    property, divided by the number of acres by which that property differed from
    appellants’ property, would result in per-acre values of $980, $1,282, $1,017
    and $1,007 for the four properties considered by the Board.
    9
    the same factual allegations as the first cause of action, leaving only the tax
    refund claim for trial.
    After a bench trial, the court ruled in favor of respondent, finding the
    property was not obtained in an open market transaction, there was
    substantial evidence to support the Board’s conclusion as to the assessed
    value of the property, and appellants’ due process rights were not violated by
    the procedural issues appellants raised. Judgment was filed on August 26,
    2019.
    DISCUSSION
    “The proper scope of review of assessment decisions is well established.
    (Bret Harte Inn, Inc. v. City and County of San Francisco (1976) 
    16 Cal.3d 14
    ,
    21–23.) ‘When the assessor utilizes an approved valuation method, his
    factual findings and determinations of value based upon the appropriate
    assessment method are presumed to be correct and will be sustained if
    supported by substantial evidence.’ (Service America Corp. v. County of
    San Diego (1993) 
    15 Cal.App.4th 1232
    , 1235 (Service America Corp.).)
    However, where the taxpayer attacks the validity of the valuation method
    itself, the issue becomes a question of law subject to de novo review.
    (Ibid.; see GTE Sprint [Communications Corp. v. County of Alameda (1994)]
    26 Cal.App.4th [992,] 1001.)” (Elk Hills Power, LLC v. Board of
    Equalization (2013) 
    57 Cal.4th 593
    , 606.) Here, appellants’ argument that
    the Board was required to accept their purchase price as the taxable value of
    the property unless respondent proved by a preponderance of the evidence
    the property was not purchased in an open market, arms length transaction
    is a challenge to the methodology of valuation, presenting a question of law.
    The same is true to the extent appellants argue the properties used in the
    Assessor’s comparative sales analysis were not sufficiently similar to the
    10
    subject property to be used for that purpose. To the extent appellants
    challenge the application of the comparable sales analysis—the findings of
    fact and determinations of value resulting from the analysis—we review for
    substantial evidence.
    I.
    “California Constitution, article XIII, section 1, provides that all
    property ‘is taxable and shall be assessed at the same percentage of fair
    market value,’ with certain exceptions not relevant here. California
    Constitution, article XIII A, section 1, places certain restrictions on the
    assessment of taxes on real property and does so by reference to the ‘full cash
    value’ of the property. Section 2, subdivision (a) of article XIII A defines “full
    cash value’ for properties purchased after 1975 as ‘the appraised value’ of the
    property at the time of purchase. Where the full cash value is established
    upon purchase and sale of the property, the term ‘full cash value’ has the
    same meaning as fair market value measured at the date of such purchase.
    (Blackwell Homes v. County of Santa Clara (1991) 
    226 Cal.App.3d 1009
    ,
    1013.)” (Maples v. Kern County Assessment Appeals Bd. (2002) 
    103 Cal.App.4th 172
    , 179–180 (Maples).)
    Section 110, subdivision (a) provides that “ ‘full cash value’ or ‘fair
    market value’ means the amount of cash or its equivalent that property
    would bring if exposed for sale in the open market under conditions in which
    neither buyer nor seller could take advantage of the exigencies of the
    other, and both the buyer and the seller have knowledge of all of the uses and
    purposes to which the property is adapted and for which it is capable of being
    used, and of the enforceable restrictions upon those uses and purposes.”
    The tax rules promulgated by the SBE further provide: “In addition to
    the meaning ascribed to them in the Revenue and Taxation Code, the words
    11
    ‘full value’, ‘full cash value’, ‘cash value’, ‘actual value’, and ‘fair market
    value’ mean the price at which a property, if exposed for sale in the open
    market with a reasonable time for the seller to find a purchaser, would
    transfer for cash or its equivalent under prevailing market conditions
    between parties who have knowledge of the uses to which the property may
    be put, both seeking to maximize their gains and neither being in a position
    to take advantage of the exigencies of the other. [¶] When applied to real
    property, the words ‘full value’, ‘full cash value’, ‘cash value’, ‘actual value’
    and ‘fair market value’ mean the price at which the unencumbered or
    unrestricted fee simple interest in the real property (subject to any legally
    enforceable governmental restrictions) would transfer for cash or its
    equivalent under the conditions set forth in the preceding sentence.” (Cal.
    Code Regs., tit. 18, § 2, subd. (a).)
    The presumption appellants rely upon in this case is established in
    subdivision (b) of section 110: “For purposes of determining the ‘full cash
    value’ or ‘fair market value’ of real property, other than possessory interests,
    being appraised upon a purchase, ‘full cash value’ or ‘fair market value’ is the
    purchase price paid in the transaction unless it is established by a
    preponderance of the evidence that the real property would not have
    transferred for that purchase price in an open market transaction. The
    purchase price shall, however, be rebuttably presumed to be the ‘full cash
    value’ or ‘fair market value’ if the terms of the transaction were negotiated at
    arms length between a knowledgeable transferor and transferee neither of
    which could take advantage of the exigencies of the other. ‘Purchase price,’
    as used in this section, means the total consideration provided by the
    purchaser or on the purchaser's behalf, valued in money, whether paid in
    money or otherwise. . . .”
    12
    The tax rules elaborate that in valuing real property as a result of a
    change in ownership, “it shall be rebuttably presumed that the consideration
    valued in money, whether paid in money or otherwise, is the full cash value
    of the property. The presumption shall shift the burden of proving value by a
    preponderance of the evidence to the party seeking to overcome the
    presumption. The presumption may be rebutted by evidence that the full
    cash value of the property is significantly more or less than the total cash
    equivalent of the consideration paid for the property. A significant deviation
    means a deviation of more than 5% of the total consideration.” (Cal. Code
    Regs., tit. 18, § 2, subd. (b).)
    Appellants argue that under the above provisions, the Assessor had the
    burden of proving the foreclosure sale in which they purchased the property
    was not an open market transaction and establishing by a preponderance of
    the evidence that the price would have been different if the sale had taken
    place under open market conditions. Appellants complain that, despite the
    Assessor’s failure to produce evidence the transaction was not an open
    market sale, the Board improperly rejected the purchase price presumption
    by relying upon the Board chairman’s personal opinion that a public trustee
    auction is never an open market sale and Annotation No. 460.0013,
    expressing the same view. Reliance upon the Board chairman’s opinion,
    appellants’ urge, violates regulations requiring the Board to render its
    decision “on the basis of proper evidence at the hearing.” (Cal. Code Regs.,
    tit. 18, § 302) As to the annotation, appellants emphasize that SBE
    annotations, as staff interpretations of statutory law, are not binding
    authority. (Helene Curtis, Inc. v. Assessment Appeals Bd. (1999) 
    76 Cal.App.4th 124
    , 132; Yamaha, 
    supra,
     19 Cal.4th at p. 7.)
    13
    Appellants’ position assumes the rebuttable purchase price
    presumption applies in every case, and controls absent evidence the
    particular purchase in question was not an arms length, open market
    transaction. The Board (and superior court) found the presumption does not
    apply to purchases at foreclosure sales because such sales, by their nature,
    are not open market transactions and, therefore, the precondition to
    application of the presumption is not met.10 The SBE has expressed this view
    not only in Annotation No. 460.0031
    (https://www.boe.ca.gov/lawguides/property/current/ptlg/annt/460-0000-
    all.html> [as of Dec. 31, 2020]), but also Annotation No. 848.0003
    ( [as of Dec. 31, 2020]).11 We agree.
    “ ‘[I]t is common knowledge that at forced sales such as a trustee’s sale
    the full potential value of the property being sold is rarely realized.’ (Strutt v.
    Ontario Sav. & Loan Assn. (1972) 
    28 Cal.App.3d 866
    , 876; see also Alliance
    Mortgage Co. v. Rothwell (1995) 
    10 Cal.4th 1226
    , 1236 [property’s price at
    trustee’s sale ‘is not deemed the equivalent of the property’s fair market
    value’].)” (Melendrez v. D & I Investment, Inc. (2005) 
    127 Cal.App.4th 1238
    ,
    1254.) Alliance Mortgage Co., at pages 1236–1237 (Alliance Mortgage),
    10Of course, as recognized by the rebuttable nature of the presumption,
    “even an arm’s length, open market transaction may involve factors that
    skew the purchase price and make it an unreliable indicator of the fair
    market value.” (Dennis v. County of Santa Clara (1989)

    , 1028.)
    11 Annotation No. 848.0003 (2016) states: “Purchases at foreclosure
    auctions are not considered open-market transactions because they are, by
    definition, ‘forced sales’ characterized by nonmarket conditions. Thus, the
    purchase price presumption does not apply to properties that are purchased
    at auction because they are not ‘open-market’ transactions as contemplated
    by Revenue and Taxation Code section 110(b).”
    14
    explained why “[t]he price at a foreclosure sale is not deemed the equivalent
    of the property’s fair market value” with a quotation from BFP v. Resolution
    Trust Corp. (1994) 
    511 U.S. 531
     (BFP), “ ‘An appraiser’s reconstruction of
    “fair market value” could show what similar property would be worth if it did
    not have to be sold within the time and manner strictures of state-prescribed
    foreclosure. But property that must be sold within those strictures is
    simply worth less. No one would pay as much to own such property as he
    would pay to own real estate that could be sold at leisure and pursuant to
    normal marketing techniques.’ ” (Alliance Mortgage, at p. 1237.)
    BFP further explained: “[M]arket value, as it is commonly understood,
    has no applicability in the forced-sale context; indeed, it is the very antithesis
    of forced-sale value. ‘The market value of . . . a piece of property is the price
    which it might be expected to bring if offered for sale in a fair market; not the
    price which might be obtained on a sale at public auction or a sale forced by
    the necessities of the owner, but such a price as would be fixed by negotiation
    and mutual agreement, after ample time to find a purchaser, as between a
    vendor who is willing (but not compelled) to sell and a purchaser who desires
    to buy but is not compelled to take the particular . . . piece of property.’
    Black’s Law Dictionary 971 (6th ed. 1990). In short, ‘fair market value’
    presumes market conditions that, by definition, simply do not obtain in the
    context of a forced sale.” (BFP, supra, 511 U.S. at pp. 537–538.)
    Appellants argue that the sale in the present case was not “forced”
    because the trustee “was a willing party” and, according to appellant’s
    testimony, the public auction was noticed for seven months before it actually
    took place and there was “ ‘no time limit or a minimum price paid by law, nor
    were there any additional liens by a public entity’ to be paid.” Appellants
    also state that their purchase met a minimum acceptable value that was
    15
    established prior to the trustee’s sale,12 and emphasize that the property
    failed to sell when it was listed on the open market in 2005, 2006, and 2009.
    These factors, they maintain, distinguish the particular trustee’s sale in the
    present case from the “reasoning” of Alliance Mortgage.
    The argument is not persuasive. All foreclosure sales must be
    conducted in accordance with statutory requirements regarding notice,
    timing, bids, and other particulars. The trustee is not attempting to
    maximize gain, as would be expected of a seller in an open market
    transaction; he or she is attempting to recoup the amount of a defaulted loan,
    regardless of the actual value of the security property, and the lender does
    not keep any surplus over the amount of the secured obligation and costs of
    foreclosure. (Civ. Code, § 2924k; Zieve, Brodnax & Steele, LLP v. Dhindsa
    (2020) 
    49 Cal.App.5th 27
    , 30–31.) “ ‘[N]either appraisal
    nor judicial determination of fair value is required’ ” (Alliance Mortgage,
    
    supra,
     10 Cal.4th at p. 1236, quoting Sheneman, Cal. Foreclosure: Law and
    Practice (1994) § 6.01, p. 6–3), and a foreclosure sale is valid even if there is
    “great disparity between the foreclosure price and the value of the property.”
    (Knapp v. Doherty (2004) 
    123 Cal.App.4th 76
    , 94.)
    In the present case, as the Board indicated in its findings, the trustee’s
    sale required bidders to pay a cash deposit in order to participate and to pay
    the total purchase price within three days, thus excluding potential
    purchasers relying upon traditional financing; the seller was forced to sell in
    order to recover anything on the defaulted loan; and the sale lacked typical
    real estate marketing. The Board’s statement that the “seller was not
    12Appellant supports this assertion with citation to the public auction
    notice and trustee’s deed in the administrative record. As far as we can tell,
    these documents do not provide the stated information.
    16
    necessarily a ‘willing’ seller at the auction price” is certainly justified by the
    fact that the price appellants paid—153,153,806.41—was considerably less
    than the $228,460.69 outstanding debt secured by the property. As for the
    fact that the property did not sell in 2005, 2006, and 2009, appellants offer no
    information about the market conditions or other circumstances of those
    attempted sales and how they compare to the situation at the time of the sale
    in 2013.13
    In short, whatever distinctions there might be between the specific
    foreclosure sale here and another held more quickly, or on an obligation
    subject to additional liens, a foreclosure sale is by nature not an open market
    transaction supporting application of the section 110 purchase price
    presumption.14
    13According to the appraiser, the property was listed for sale in 2009 at
    around $500,000, and the owners were attempting to sell it as two separate
    parcels despite the two having been merged.
    It is also worth noting that appellant’s testimony that the property sold
    for $125,000 in 2000 (without the home, which was subsequently added at a
    cost of about $85,000) is of little relevance to the property’s value 13 years
    later.
    14 Appellants’ attempt to liken the foreclosure sale here to the sale in
    Maples is not convincing. Maples involved sale of a petroleum reserve by the
    federal Department of Energy in a sealed bid auction, with the minimum
    acceptable bid set after appraisal by independent appraisers. (Maples, supra,
    103 Cal.App.4th at pp. 176–177.) The solicitation for bids encouraged
    offerors to “ ‘submit offers at prices and on terms which maximize the value
    to the Government’ ” because “some offerors may be eliminated from further
    consideration before discussions are held,” and the court observed that the
    Department of Energy “adopted a tough negotiating position.” (Maples, at
    p. 185.) This situation is a far cry from a foreclosure sale at which the
    property must be sold to the highest bidder on the day of the auction. (Civ.
    Code, § 2924g, subd. (a).)
    17
    Appellants’ argument that the Board improperly relied upon the
    chairman’s opinion that foreclosure sales are not open market transactions
    necessarily depends on the faulty premise that this point must be proven by
    the evidence in any given case. Despite being framed as an “opinion” in the
    chairman’s remarks during the hearing (and those of other members), the
    Board’s conclusion that a foreclosure sale is not considered an open market
    transaction for purposes of determining fair market value was an
    interpretation of law, not a factual conclusion required to be drawn from
    evidence in the case regarding this particular transaction.
    Nor did the Board act improperly in considering the SBE annotation.
    While not dispositive, such agency interpretations are “entitled to
    consideration and respect by the courts” (Yamaha, supra, 19 Cal.4th at p. 7)
    and, no less so, by the Board. Here, as discussed, the annotation expressed a
    view entirely consistent with legal authority.
    II.
    Even where the purchase price presumption applies, it may be rebutted
    by evidence “that the fair market value of the property is otherwise.” (Dennis
    v. County of Santa Clara, supra, 215 Cal.App.3d at p. 1028.) Here, the Board
    found the comparable sales analysis established the purchase price was
    below the fair market value of the property. Appellants maintain the
    comparative sales analysis was flawed.
    Section 402.5 provides, “When valuing property by comparison with
    sales of other properties, in order to be considered comparable, the sales shall
    be sufficiently near in time to the valuation date, and the properties sold
    shall be located sufficiently near the property being valued, and shall be
    sufficiently alike in respect to character, size, situation, usability, zoning, or
    other legal restriction as to use unless rebutted pursuant to Section 402.1, to
    18
    make it clear that the properties sold and the properties being valued are
    comparable in value and that the cash equivalent price realized for the
    properties sold may fairly be considered as shedding light on the value of the
    property being valued. ‘Near in time to the valuation date’ does not include
    any sale more than 90 days after the valuation date.” Section 402.1
    establishes a presumption that restrictions on a property will continue and
    will affect its value, and describes circumstances in which the presumption
    may be rebutted.15
    Tax rule 4 provides that “[w]hen reliable market data are available
    with respect to a given real property, the preferred method of valuation is by
    reference to sales prices,” and sets forth requirements to be met in using this
    method. (Cal. Code Regs., tit. 18, § 4.) These include a requirement that the
    assessor “[m]ake such allowances as he [or she] deems appropriate for
    differences between a comparable property at the time of sale and the subject
    property on the valuation date, in physical attributes of the properties,
    location of the properties, legally enforceable restrictions on the properties’
    use, and the income and amenities which the properties are expected to
    produce.” (Cal. Code Regs., tit. 18, § 4, subd. (d).)
    15 Section 402.1, subdivision (b), provides, “There is a rebuttable
    presumption that restrictions will not be removed or substantially modified
    in the predictable future and that they will substantially equate the value of
    the land to the value attributable to the legally permissible use or uses.”
    “Grounds for rebutting the presumption may include, but are not necessarily
    limited to, the past history of like use restrictions in the jurisdiction in
    question and the similarity of sales prices for restricted and unrestricted
    land.” (§ 402.1, subd. (c).) “In assessing land with respect to which the
    presumption is unrebutted, the assessor shall not consider sales of otherwise
    comparable land not similarly restricted as to use as indicative of value of
    land under restriction, unless the restrictions have a demonstrably minimal
    effect upon value.” (§ 402.1, subd. (d).)
    19
    Appellants argue that in order to comply with tax rule 4, assessors may
    not provide the Board with “raw data within a range of values” (Main & Von
    Karman Associates v. County of Orange (1994) 
    23 Cal.App.4th 337
    , 343
    [disapproving assessor “giving the [Board] the raw data and stating that the
    assessor’s opinion was within the ‘range of values’ shown by the data”]) and
    must give each adjustment “ ‘separate and serious consideration’ ” (Midstate
    Theatres, Inc. v. County of Stanislaus (1976) 
    55 Cal.App.3d 864
    , 881
    (Midstate Theatres)). Midstate Theatres found that rule 4 was not complied
    with where an assessor made an “overall adjustment” without specific
    adjustments for the factors enumerated in rule 4. (Midstate Theatres, at
    pp. 880–881.) In Main & Von Karman Associates, the assessor erroneously
    believed the requirements of tax rule 4 were “guidelines” and did not make
    adjustments to the raw data provided to the Board. (Main & Von Karman
    Associates, at p. 343.) The problems addressed in these cases do not appear
    in the present one. The comparables spread sheet shows specific adjustments
    for quality of the properties, square footage of the homes, number of
    bedrooms, condition, lot size, an attached garage on one comparable, and
    living space. The appraiser noted that appellants’ property was slightly
    further from the public road than the comparables, but testified he did not
    feel an adjustment was needed because the property was closer to services.
    He testified that all but one of the comparison properties had PG&E hook-ups
    but “[t]he market wasn’t showing any need” for an adjustment on this basis.
    It is apparent the Assessor considered the specific attributes of and
    differences between the properties and made adjustments as deemed
    appropriate.
    Appellants argue that one of the properties used as a comparable,
    “Comp 2,” was not appropriate for this purpose because it was zoned half
    20
    “TPZ” (timberland preserve zone) and half agricultural, while appellants’
    property is zoned “unclassified.” Zoning is one of the restrictions on use of
    land an assessor is required to consider with respect to the valuation of
    property. (§ 402.1, subd. (a)(1).)
    Appellants point to the statement in Jones v. County of Los Angeles
    (1981) 
    114 Cal.App.3d 999
    , 1006, that “[t]he purported use of the ‘comparable
    sales’ method based on sales of property which are not subject to the same
    limitation on use as the property in question is not a valid method of valuing
    the property.” The property in Jones was designated on the county’s general
    plan as “open space” and subject to an injunction prohibiting the county from
    issuing building or grading permits, approving subdivision maps, conditional
    or special use permits or variances, or adopting zoning ordinances regarding
    the property. The court held that properties not subject to these restrictions
    could not be used as comparables: “It seems evident that when property is
    the subject of a specific injunction limiting its use, there can be no
    comparison of value drawn from sales of property which are unfettered by
    such injunction.” (Id. at p. 1007.) Similarly, Meyers v. County of Alameda
    (1977) 
    70 Cal.App.3d 799
    , 807–808, held that property zoned agricultural
    could not be valued by comparison with sales of properties not similarly
    restricted absent evidence that the agricultural restriction had “ ‘a
    demonstrably minimal effect upon value.’ ”
    Here, the appraiser described the “unclassified” zoning applicable to
    appellant’s property as “the least stringent zoning that there is for this type
    of property.” Appellants’ situation is the opposite of that in the cases they
    rely upon, as use of a more restrictively zoned property would not artificially
    inflate the value of appellants’ property. (See § 402.1, subd. (d) [precluding
    assessment of land under restriction by comparison to land not similarly
    21
    restricted unless restrictions have demonstrably minimal effect on value].) If
    anything, the more restrictive zoning of Comp 2 would have worked to
    appellants’ advantage by reducing the value of the comparison property.16 As
    the court explained in Dressler v. County of Alpine, (1976) 
    64 Cal.App.3d 557
    ,
    569–570, section 402.5 “demands only ‘sufficient [similarity] to make it clear’
    that the property sold may ‘fairly be considered’ as bearing upon the
    assessment appraisal.” Given the difficulty of finding precisely comparable
    properties in the circumstances of this case, consideration of Comp 2 was not
    impermissible.
    Appellants also challenge as arbitrary the $500 per acre figure the
    Board found to be “more acceptable” than the appraiser’s higher amount for
    adjusting the differences in lot size between the comparables and the subject
    property. Appellants argue that when they requested the Assessor’s
    calculations for the comparable properties, they were not provided any
    calculations pertaining to the adjustment for disparities in acreage,17 and
    16Appellant argued at the July 2015 hearing that Comp 2 could not be
    used because “by the appraiser’s own admission [the zoning] doesn’t allow it
    to be used as a comparable.” The “admission” was the appraiser’s testimony
    that a property initially considered in a prior set of comparisons could not be
    used because it was zoned TPZ. The appraiser explained that he had first
    looked at properties “more specific to [appellants’] area” and “[t]he problem
    we were running into is these large parcels were all TPZ and they were all
    vacant land. . . . They weren’t comparable properties and so we weren’t using
    those. And I did say we didn’t use those TPZ lands for that specific instance.”
    Comp 2 was only one of the properties ultimately used in the comparative
    sales analysis.
    17 The Assessor’s letter responding to appellant’s request stated, “This
    document has been provided to you on November 13, 2014, copy attached.”
    The documents following this letter in the administrative record include a
    spreadsheet showing the comparable properties and adjustment amounts for
    lot size and several other variables (quality, square feet, bedrooms, condition,
    22
    that appellant’s own calculations—derived by dividing the land value stated
    on the property tax bill for each property by its number of acres—indicate per
    acre values for the comparables ranging from $9,132 per acre (Comp 3) to
    $28,701 per acre (Comp 1). Indeed, appellant refers to his calculations as the
    “undisputed value per acre of the comparable properties” and “the only lot
    size value evidence with comparable properties in the administrative record.”
    Obviously, accepting these calculated per acre values would not serve
    appellants’ interests, as they would significantly increase the value of the
    comparables and, therefore, appellants’ property. Moreover, appellant’s
    calculations assume a uniform per acre value regardless of lot size. The
    Board chairman explained that “division of a small acreage parcel and the
    per acre value is not relevant to a large parcel. Each . . . additional acre is
    worth less than the last one . . . . A hundred acre parcel is not worth twice a
    50 acre parcel . . . .”
    One of appellants’ arguments indicates a fundamental
    misunderstanding of the Board’s use of the $500 per acre figure. The SBE
    Assessors’ Handbook, in a section on the comparative sales approach to
    valuation of manufactured homes, states that when a manufactured home
    and the site it occupies are sold as a unit, “[w]hen an accurate estimate of
    land value is possible, the residual offers a good indicator of the home’s
    value.” (SBE, Assessors’ Handbook, Assessment of Manufactured Homes &
    Parks (Nov. 2001) § 511, p. 33
     [as of Dec. 31,
    attached garage, detached garage), but no calculations explaining the
    adjustment amounts.
    23
    2020].)18 Inverting this reasoning, appellant calculates that the Board’s $500
    per acre value would give his 160 acres a value of $80,000, which, subtracted
    from the Board’s total valuation of $335,000, would result in a value of
    $255,000 for the manufactured home, while the highest value the Assessor
    assigned to the home was $106,165.19 Appellants’ reasoning appears to be
    that this calculation shows the $500 per acre value must be inaccurate. But
    18  “ ‘[A]ssessors’ handbooks are not regulations and do not possess the
    force of law . . . ,’ but ‘they serve as a primary reference and basic guide for
    assessors, and have been relied upon and accorded great weight in
    interpreting valuation questions. [Citation.]’ (Sky River [LLC v. County of
    Kern (2013)] 214 Cal.App.4th [720,] 735; see Watson Cogeneration Co. v.
    County of Los Angeles (2002) 
    98 Cal.App.4th 1066
    , 1070, fn. 2.)” (SHC Half
    Moon Bay, LLC v. County of San Mateo (2014) 
    226 Cal.App.4th 471
    , 485.)
    Appellants ask us to take judicial notice of several sections of the SBE
    Assessors’ Handbook; respondent objects, primarily because no such request
    was made in the trial court. We grant the request. A reviewing court may
    take judicial notice of matters not before the trial court even though it need
    not do so. (Brosterhous v. State Bar (1995) 
    12 Cal.4th 315
    , 325; Doers v.
    Golden Gate Bridge, etc. Dist. (1979) 
    23 Cal.3d 180
    , 184, fn. 1.) “It is well
    established that assessor’s handbooks are subject to judicial notice by the
    courts.” (Hunt-Wesson Foods, Inc. v. County of Alameda (1974) 
    41 Cal.App.3d 163
    , 180.) They are routinely discussed in cases reviewing issues such as
    involved in the present case. (E.g., Elk Hills Power, LLC v. Board of
    Equalization, 
    supra,
     57 Cal.4th at p. 616; SHC Half Moon Bay, LLC v.
    County of San Mateo, supra, 226 Cal.App.4th at p. 485; Sky River LLC v.
    County of Kern, supra, 214 Cal.App.4th at p. 727.) The portions appellants
    ask us to judicially notice add to material already in the record and are
    directly relevant to legal issues before us.
    19 Appellants express confusion over the Assessor’s enrolled value for
    the improvements on their property. They refer to a 2019 letter in which the
    Assessor stated that the $335,000 base year value was allocated $111,000 for
    the land in parcel 101-222-006, $174,000 for the land in parcel 101-131-001,
    and $50,000 to improvement value. We decline appellants’ request to take
    judicial notice of the Assessor’s letter, which was written and received long
    after the proceedings before us on this appeal.
    24
    the Board did not find appellants’ land had a value of $500 per acre; it found
    $500 per acre to be the appropriate amount to use in adjusting the value of
    comparison properties with considerably less acreage than appellants’
    property, and reduced the value of the comparables accordingly.
    Appellant is correct that the record does not explain how the Board
    reached the specific amount it found reasonable for the adjustment of lot size
    differences. But this is not necessarily fatal to the Board’s ultimate
    conclusion. Tax rule 4 directs the assessor, in applying the comparative sales
    method of valuation, to “[m]ake such allowances as he [or she] deems
    appropriate for differences between a comparable property at the time of sale
    and the subject property on the valuation date, in physical attributes of the
    properties, location of the properties, legally enforceable restrictions on the
    properties' use, and the income and amenities which the properties are
    expected to produce.” (Cal. Code Regs., tit. 18, § 4, subd. (d).) This directive
    necessarily allows for a degree of inexactitude in the adjustments;
    mathematical precision is not required. (See Service America Corp., supra,
    15 Cal.App.4th at p. 1242 [imputed value of nontaxable intangible factors
    affecting value of property interest “will bear some characteristics of
    arbitrary selection”].)20
    20 Service America Corp., supra, 
    15 Cal.App.4th 1232
    , involved
    valuation by means of the income capitalization method of the possessory
    interest of a franchisee holding the exclusive right to sell food and beverages
    in a sports stadium. (Id. at pp. 1234, 1236.) The court observed that due to
    the beneficial location, it would be reasonable to value the franchisee’s
    possessory interest at a considerably greater sum than the square-foot rental
    value of a comparable establishment not located in a sports stadium, but that
    the county was also entitled to consider the value of the nontaxable exclusive
    concession and business value that also contributed to the franchisee’s
    profitability. (Id. at pp. 1241–1242.) “It seems to us that some form of
    25
    Appellants next contend the comparison properties were stale. Section
    402.5 requires that in order to be considered comparable, sales of other
    properties “shall be sufficiently near in time to the valuation date.” “ ‘Near in
    time to the valuation date’ does not include any sale more than 90 days after
    the valuation date.” (§ 402.5.) Accordingly, Property Tax Rules, rule 324(d),
    provides that the Board “shall not consider a sale if it occurred more than 90
    days after the date for which value is being estimated.” (Cal. Code Regs.,
    tit. 18, § 324, subd. (d).) The timing of sales is relevant because
    “[c]omparable sales occurring under different market conditions may require
    adjustment so that they reflect the same market conditions as the property
    being appraised.” (SBE, Assessors’ Handbook, § 501, p. 91
     [as of Dec. 31, 2020].)
    “Economic variables affecting demand and supply that have shifted and/or
    inflationary or deflationary forces in the economy are the causes for this
    adjustment. . . . Because of the complexity of this adjustment, it should be
    used with care. As a general rule, it is preferable to use comparable sales
    occurring near the valuation date of the subject property, thereby avoiding
    the need for this adjustment.” (Id. at p. 92.)
    ‘imputed’ value must be utilized by the assessor to determine a fair ‘rental’
    value for the property. As we have stated, this imputed value need not be
    limited by consideration of comparable values for rental properties not
    associated with a stadium. Obviously whatever final computation is made
    will bear some characteristics of arbitrary selection. The appeals board may
    determine that some factor of increase over comparable values is
    appropriate—150 percent or 200 percent or some other percentage.
    Whatever imputed value is selected, however, will presumably not result in
    complete utilization of the agreed $19 million valuation of the total
    enterprise. The excess of the $19 million over the imputed value of the
    possessory interest will then appropriately relate to the intangible,
    nontaxable, assets Service America admittedly possesses.” (Id. at p. 1242.)
    26
    The valuation date for appellants’ property was July 12, 2013. The
    sales dates for the comparables ultimately considered by the Board (Comp 1,
    2, 3, Sawdust Trail) were November 2012, April 2013, June 2013, and July
    2012. Two of these were at least roughly within 90 days of the valuation
    date; one was a year prior and the fourth, eight months prior. Again, the
    difficulty of obtaining comparable sales data for unique rural properties such
    as appellants’ warrants some lenience in the required temporal proximity of
    the comparison sales to the valuation date for appellants’ property.
    The record reflects that the Board was well aware of, and concerned
    about, the differences between appellants’ property and the comparison
    properties used by the Assessor. It addressed this point in its written
    decision: “The Subject Property and the comparable properties in the
    Administrative Record, by their very nature as generally remote and rural
    properties, are in some ways each unique in their own right. This makes
    determination of a reasonable fair market value based on the Administrative
    Record challenging but not impossible. The Board is not required to be able
    to calculate a precise fair market value by mathematical precision, but only
    to reach an opinion on a reasonable fair market value within its discretion,
    based on the record.”
    The Board’s observation is correct. “Standards of comparability can
    never be treated in absolute terms. Even relatively poor data can ‘fairly be
    considered as shedding light on the value of the property being valued’ (Rev.
    & Tax. Code, § 402.5) if it is the best or only data available. Admittedly in
    this case, only poor comparable data was available, and under such
    circumstances, the use by the assessor of his four comparables was merely
    the use of the best available market data. As such, in spite of major
    dissimilarities, it cannot be said use of the comparables violated Revenue and
    27
    Taxation Code section 402.5 or rule 4.” (Midstate Theatres, supra, 55
    Cal.App.3d at p. 880.) As we noted in DFS Group, L.P. v. County of San
    Mateo (2019) 
    31 Cal.App.5th 1059
    , 1089, “it can be difficult to value unusual
    or unique properties, and therefore considering comparable values for
    properties that are not precisely similar may be appropriate even if not alone
    dispositive. (See Service America Corp., supra, 15 Cal.App.4th at p. 1242.)
    Further, no attempt at valuing a unique or unusual property will likely be
    precise or flawless. The fact that precisely similar comparable properties
    may not exist, or that valuation information may not be available for
    comparable properties, is not the fault of the parties or the experts. These
    may simply be unavoidable realities.”
    III.
    Appellants raise a number of other challenges to the Board’s actions
    and decision. First, they complain that the Board mishandled the Assessor’s
    violation of sections 408 and 1606 by failing to take steps to remediate the
    disadvantage caused by the Assessor’s failure to provide them with access to
    requested information on calculations and evidence that the sale was not an
    open market sale. Section 408, subdivision (e)(2), requires an assessor to
    allow an assessee, upon written request, to inspect or copy all information
    relating to appraisal and assessment of the assessee’s property. Section 1606
    provides for an exchange of information ahead of a hearing on an application
    for change of assessment. The statute directs that “[w]henever information
    has been exchanged pursuant to this section the parties may not introduce
    evidence on matters not so exchanged unless the other party consents
    to the introduction,” and if a party introduces new material relating to the
    information received from the other party, the other party must be granted a
    reasonable continuance if requested. (§ 1606, subd. (d).)
    28
    We see no violation of the information exchange requirements.
    Appellants asked the Assessor for “calculations done on what the Assessor’s
    office deems as comparable properties on list dated 11-3-14.” In response, the
    Assessor stated, “This document has been provided to you on November 13,
    2014, copy attached.” As earlier described, the documents following this
    letter in the administrative record include a spreadsheet showing the
    comparable properties and adjustment amounts for lot size and several other
    variables. These adjustment amounts are the Assessor’s calculations: The
    spreadsheet shows the starting value of each property, the amounts added or
    subtracted due to differences from appellants’ property and the resulting
    value used as a comparable. “If the exchange of information provides
    reasonable notice to the opposition concerning the subject matter to be
    presented at the hearing through the testimony of witnesses and evidence,
    the statute has been complied with.” (Bank of America v. County of
    Fresno (1981) 
    127 Cal.App.3d 295
    , 307.)
    As for appellants’ request for “documented evidence that the
    transaction on subject properties was not an open market, arms length
    agreement, willing buyer and seller transaction,” the Assessor responded that
    “[o]ur office does not have any documents responsive to this request.”
    Appellants asked the Board to exclude the SBE annotation from
    consideration, arguing the Assessor’s reliance upon the annotation after
    failing to disclose it in response to their request for information violated the
    statutory requirements for exchange of information. As the Board explained
    in its decision, however, the annotation was legal authority offered to support
    the Assessor’s position, not factual information relating to the property.
    Appellants raise several matters as violations of their due process
    rights. They maintain they were denied a fair hearing to disqualify Board
    29
    member Mitchell, when the Assessor was permitted to testify concerning the
    member’s qualifications without being sworn and appellants’ objections were
    summarily dismissed. They argue they were denied a fair hearing due to the
    lack of calculations for the adjustments of the comparable sales, which they
    maintain deprived them of the opportunity to cross examine the Assessor
    about the calculations. They further argue they were denied a fair hearing
    on June 8, 2017, due to the participation of Board member Mitchell, the lack
    of substantial evidence to demonstrate the Assessor met her burden of
    overcoming the purchase price presumption, the admission and use of
    unreliable evidence, the use of comparable sales evidence from properties
    that were not comparable to theirs, the Board acting arbitrarily in valuing
    their property, and the Board failing to issue adequately detailed findings.
    Many of these issues need not be further addressed: We have already
    concluded the Board acted appropriately with respect to the purchase price
    presumption and the comparable sales valuation, including the complaints
    about underlying calculations, unreliable comparables, and arbitrary
    valuation, which appellants now frame as due process violations. What
    remains are appellants’ complaints about their attempt to disqualify Board
    member Mitchell and the Board’s findings.21
    21Respondent argues that appellants’ due process claims were
    dismissed by the trial court, when it granted the respondent’s motion for
    summary adjudication of the second through fifth causes of action of the
    complaint due to appellants’ failure to explain their theories or cite legal
    authority, and that we should reject any reference to these causes of action
    because appellants have not challenged the trial court’s summary
    adjudication ruling. The respondent’s portrayal is not accurate.
    Respondent’s motion for summary adjudication argued not only that
    appellants failed to plead facts sufficient to state the second through fifth
    causes of action but also that those causes of action were barred by immunity
    30
    With respect to the disqualification hearing, the unsworn statement the
    Assessor volunteered at the hearing, in full, was as follows: “Mari Wilson,
    Humboldt County Assessor. I would just like to say, at no time did we ever
    feel bias toward our office through the whole proceeding. We’ve not had any
    contact with Mr. Mitchell outside of the hearings, and he certainly put us to
    our marks several times throughout the proceeding. So we do not feel any
    bias toward our office nor have we worked with him.” It is difficult to see how
    this statement could have prejudiced appellants, and appellants offer neither
    explanation nor authority supporting their assertion that their due process
    rights were violated. Issues not supported by argument or authority are
    treated as forfeited on appeal. (San Mateo Coastal Landowners’ Assn. v.
    County of San Mateo (1995) 
    38 Cal.App.4th 523
    , 559; Badie v. Bank of
    America (1998) 
    67 Cal.App.4th 779
    , 784.) The same is true for appellants’
    complaint that their objections to this unsworn testimony were summarily
    dismissed.22
    or otherwise unavailable in a tax case. The trial court did not explain its
    reasoning for granting summary adjudication. Respondent’s basic position
    was that appellants’ sole available cause of action was for a tax refund, and
    respondent expressly recognized that any alleged due process issues with the
    hearing and decision could be resolved as part of a tax refund action.
    Appellants’ failure to challenge the ruling is not a basis for rejecting their
    claims of due process violations in the Board’s handling of their case.
    22Appellant did not object to the Assessor’s statement at the
    disqualification hearing, but raised the lack of oath in an email prior to the
    remand hearing, questioning the propriety of the disqualification hearing
    procedure and suggesting as alternative ways to resolve the problem that
    Mitchell recuse himself from the upcoming hearing, the appeal hearing be
    continued, or appellant “file with Superior Court relating to the contradictory
    way in which the decision was reached.” At the June 2017 hearing, appellant
    objected to Mitchell’s participation and the chairman said, “that issue has
    been resolved and we’re not interested in information about that in this
    31
    Appellants also challenge the Board’s findings as deficient in various
    ways. The Board’s written findings are required to “fairly disclose the board’s
    determination of all material points raised by the party in his or her petition
    and at the hearing, including a statement of the method or methods of
    valuation used in appraising the property. (Rev. & Tax Code, § 1611.5; Cal.
    Code. Regs., tit. 18, § 324, subd. (e).) Appellants’ main contention with
    regard to determination of all material points is that the Board made no
    determination regarding one of their four applications for tax refund,
    application No. 14-73. Appellants argue that the Assessor should have
    reassessed the property for the lien date following their purchase, January 1,
    2014, but failed to do so until November 2014, continuing to use the prior
    owner’s value meanwhile. Appellants maintain the property should have
    been enrolled at the $153,806.41 purchase price on the lien date following
    their purchase.
    Respondent argues that this issue raised in application No. 14-73 was
    mooted by the parties’ stipulation remanding the matter to the Board. Since
    the stipulation provided for remand “to determine the value of the Subject
    property based on evidence in the administrative record of the prior [Board]
    proceedings on March 12, 2015 and July 20, 2015 (the ‘Prior Hearing’) and for
    the [Board] to issue a new decision and new findings of fact as to its
    determination of the value of the Subject Property,” respondent views the
    stipulation as having “narrowed the issues” to the question of value, mooting
    hearing.” Appellant responded, “I’m just making an objection . . . [f]or the
    record” and the chairman replied, “[T]hank you. Okay.” Appellant having
    stated his objection was “for the record,” without reference to any unresolved
    issue regarding the unsworn statement at the disqualification hearing, this
    exchange cannot fairly be characterized as a summary dismissal of the
    objection.
    32
    other issues raised by the applications. We need not determine the scope of
    the stipulation. In these proceedings, the Board determined the value of the
    property as of the date of appellants’ purchase in July 2013. Appellants’
    argument that the Assessor acted improperly with respect to the valuation of
    the property for the January 1, 2014 lien date does not include any
    explanation how this allegedly improper conduct affected the Board’s
    determination of value or otherwise prejudiced appellants.
    Relying upon the principle that “ ‘[a]s any tax proceeding
    is in invitum in nature, each step must be taken in compliance with law or
    the proceeding is void’ ” (Midstate Theatres, supra, 55 Cal.App.3d at p. 872,
    quoting Universal Cons. Oil Co. v. Byram (1944) 
    25 Cal.2d 353
    , 361),
    appellants’ general position on this appeal is that any demonstrated failure to
    comply with the law or procedural requirements requires us to declare the
    proceedings void and remand for further proceedings before the Board.
    Applying this principle to the issue of the Assessor’s valuation of the property
    for the first lien date following appellants’ 2013 purchase would make no
    sense. If the Assessor did act improperly, that historical fact will not and
    cannot change. If that past act were sufficient to invalidate the present
    proceedings, it would invalidate any future proceedings as well. This
    obviously cannot be the result.
    Appellants additionally challenge the Board’s findings as not
    explaining the Board’s use of comparable sales that were not similar in size
    to appellants’ property, not “disclosing” supporting data or calculations used
    to reconcile the differences in acreage between appellants’ property and the
    ones used for comparison, and failing to “justify with competent and properly
    entered evidence [the Board’s] decision to increase the value” of the property.
    These challenges simply recast appellants’ claims about deficiencies in the
    33
    comparable sales analysis, which we have discussed and rejected, as
    deficiencies in written findings. The Board’s findings address appellants’
    claims that their property value should be determined by their purchase price
    and that the comparable sales analysis relied on insufficiently similar
    properties, and explain the Board’s reasons for disagreeing with appellants
    and for its adjustments to the Assessor’s valuation. More detail in the
    findings is not required.
    DISPOSITION
    The judgment is affirmed.
