    OPINION
    ¶1          DSI Manteno Owner, LLC (DSI), appealed the Kankakee County Board of Review’s
    (Local Board) 2013 property tax assessment of its supportive living facility, Heritage Woods of
    Manteno (Heritage Woods), to the Illinois Property Tax Appeal Board (PTAB). Manteno
    Community Unit School District No. 5 (School District) intervened in the PTAB proceedings.
    After a hearing, the PTAB reduced Heritage Woods’s 2013 property tax assessment. The School
    District seeks our direct review.
    ¶2                                           I. BACKGROUND
    ¶3           Respondent, DSI, owns Heritage Woods, a certified supportive living facility in Manteno,
    Illinois, that houses Medicaid-eligible and private-pay residents. Under the Illinois Public Aid
    Code, 305 ILCS 5/5-5.01a (West 2012), a supportive living facility is a “free-standing facility or
    a distinct physical and operational entity within a nursing facility.” Such facilities “integrate[ ]
    housing with health, personal care, and supportive services and is a designated setting that offers
    residents their own separate, private, and distinct living units.” 
    Id.
     The Illinois Administrative
    Code (Administrative Code), 89 Ill. Adm. Code 146.200(b) (2006), defines a supportive living
    facility as:
    “a residential setting in Illinois that provides or coordinates flexible personal care
    services, 24 hour supervision and assistance (scheduled and unscheduled),
    activities, and health related services with a service program and physical
    environment designed to minimize the need for residents to move within or from
    the setting to accommodate changing needs and preferences; has an organizational
    mission, service programs and a physical environment designed to maximize
    residents’ dignity, autonomy, privacy and independence; and encourages family
    and community involvement.”
    The Illinois Department of Healthcare and Family Services (Department) established and now
    oversees the “program of supportive living facilities.” 305 ILCS 5/5-5.01a (West 2012).
    ¶4           Heritage Woods is situated on 3.49 acres of land and has 37 studio, 44 one-bedroom, and
    6 two-bedroom apartments, each of which has a private bathroom, kitchenette, and separate
    heating and cooling unit. Residents of Heritage Woods receive housekeeping, 24-hour access to
    2
    staff, and laundry machines free of charge. Common areas at Heritage Woods include a reception
    lobby, game room, salon, media room, library, and fitness center.
    ¶5          Pertinently, under section 1-55 of the Property Tax Code (35 ILCS 200/1-55 (West 2012)),
    Heritage Woods’s property taxes were based on: “One-third of the fair cash value of property, as
    determined by the Department[ of Revenue]’s sales ratio studies for the 3 most recent years
    preceding the assessment year, adjusted to take into account any changes in assessment levels
    implemented since the data for the studies were collected.” Respondent, the Local Board, used a
    fair cash value of $5,098,656 to assess Heritage Woods’s 2013 property taxes at $1,688,165. 1
    ¶6          On February 3, 2014, DSI appealed the Local Board’s assessment of $1,688,165 to
    respondent, the PTAB, under section 16-160 of the Property Tax Code (id. § 16-160), arguing that
    the Local Board erred when calculating Heritage Woods’s fair cash value under section 10-390 of
    the Property Tax Code (id. § 10-390), which states:
    “(a) Notwithstanding Section 1-55, to determine the fair cash value of any
    supportive living facility established under Section 5-5.01a of the Illinois Public
    Aid Code, in assessing the facility, a local assessment officer must use the income
    capitalization approach.
    (b) When assessing supportive living facilities, the local assessment officer
    may not consider:
    (1) payments from Medicaid for services provided to residents of
    supportive living facilities when such payments constitute income that is
    attributable to services and not attributable to the real estate; or
    1
    The Local Board has not filed a brief on appeal.
    3
    (2) payments by a resident of a supportive living facility for services
    that would be paid by Medicaid if the resident were Medicaid-eligible, when
    such payments constitute income that is attributable to services and not
    attributable to real estate.”
    ¶7            On April 16, 2014, petitioner, the School District, filed a request to intervene in the PTAB
    proceedings. The PTAB granted this request on April 29, 2014.
    ¶8                                            A. The PTAB Hearing
    ¶9            On April 11, 2017, the PTAB held a hearing on the 2013 property tax assessment of
    Heritage Woods. The hearing focused on the fair cash value of Heritage Woods as of January 1,
    2013, under section 10-390. The PTAB received testimony from David Mitchell, Chief Financial
    Officer and Vice President of Gardant Management Solutions, Inc. (Gardant), which manages
    Heritage Woods, and three certified general real estate appraisers—Keith Honegger, Michael
    MaRous, and Eric Dost. We recount each witness’s testimony below.
    ¶ 10                                             1. David Mitchell
    ¶ 11          Mitchell began his testimony by distinguishing supportive living facilities, such as Heritage
    Woods, from assisted living facilities. Mitchell stated assisted living facilities are market rate
    facilities that do not follow the same statutory guidelines as supportive living facilities. According
    to Mitchell, for Medicaid-eligible residents, supportive living facilities “agree to accept rent ***
    from the resident *** [in an amount equal] to their Social Security income less $90” and to “accept
    in full the Medicaid payment that is paid [for services] based on *** seven different regions” in
    Illinois. While assisted living facilities can have asking rental rates that are similar to those of
    supportive living facilities, an assisted living facility’s service rates vary according to the market.
    Further, assisted living facilities, generally, are not reimbursed for Medicaid-eligible residents.
    4
    ¶ 12          Next, Mitchell reviewed the Department’s 2013 schedule of estimated monthly revenues
    for a supportive living facility (Department’s schedule). The purpose of the Department’s schedule
    is “to give estimated monthly revenue for operational supportive living facilities for providing
    housing and services to Medicaid-eligible residents.” The estimated monthly revenues adopted by
    the Department vary according to Illinois region and include “funds paid by a resident for room
    and board, the Supplemental Nutrition Assistance Program (SNAP) allocation from a resident, and
    funds paid by the Department *** for services rendered to a Medicaid-eligible resident.”
    ¶ 13          The Department’s schedule estimated that the monthly revenue received for room and
    board from a single Medicaid-eligible resident of a supportive living facility was $620. Mitchell
    said this amount represented the minimum social security income ($710) minus a personal expense
    allocation ($90). Although a resident’s social security income may exceed $710, the Department
    caps the room and board charge at $620 for that single resident of the supportive living facility.
    Excess social security funds are “applied to the Medicaid services portion of their stay.” Service
    rates can be higher for private-pay residents, since, for Medicaid-eligible residents, the supportive
    living facility agrees to accept the rate provided by Medicaid. Nevertheless, the exact same services
    are provided to Medicaid-eligible and private-pay residents.
    ¶ 14          Mitchell was asked about the package price quoted to prospective residents of Heritage
    Woods. He stated the quoted package price would depend upon the type of apartment selected by
    the prospective resident. However, the quoted package price would include both room and board
    and services. Often, the prospective resident and his or her family have questions about financing,
    namely, whether the prospective resident will qualify for Medicaid or pay privately. Mitchell stated
    the quoted package price of a studio apartment at a supportive living facility, depending on that
    facility’s location, might be around $3200.
    5
    ¶ 15          Payments from residents of Heritage Woods are processed electronically and allocated
    between room and board and services. For example, if a resident receives $750 from social security
    each month, then $620 would be allocated as room and board, $90 would be allocated as a personal
    expense, and the excess of $40 would be allocated as services. Thus, all residents have the same
    room and board allocation, with any excess funds after the personal expense allocation going
    towards services.
    ¶ 16          On cross-examination, Mitchell was asked how a supportive living facility is permitted to
    apply funds exceeding the mandated $620 room and board rate to “the Medicaid services portion
    of their stay.” Mitchell cited section 146.225(c) of Title 89 of the Administrative Code, 89 Ill.
    Adm. Code 146.225(c) (2018), which states: “Any income remaining after deduction of the
    protected minimum of $90 and room and board charges shall be applied first towards medical
    expenses not covered under the Department’s Medical Assistance Program. Any income
    remaining after that shall be applied to the charges for *** services paid by the Department.”
    ¶ 17          Mitchell agreed that there is a real estate component contained in Heritage Woods’s total
    package prices that is not covered by the Department’s $620 rate. This is because $620 is allocated
    as each resident’s room and board rate, despite differences in the size of each resident’s apartment.
    For example, the difference in the asking rental rate for a studio apartment ($3425) and one-
    bedroom apartment ($3750) is $325. This $325 amount is allocated to the resident’s services even
    though he or she is receiving the exact same services as all other residents. This example can also
    be applied to one-bedroom, double-occupancy, and two-bedroom, double-occupancy, apartments,
    where the difference is $600. Mitchell agreed a resident is charged “more for the exact same
    services because [he or she] live[s] in a bigger room.”
    6
    ¶ 18          Mitchell also testified to the occupancy of the one-bedroom apartments at Heritage Woods.
    Mitchell had the following exchange with the School District’s attorney:
    “Q. All right. Well, let me get the point. Isn’t it true that each of your single
    bedrooms are code certified double—they can have two occupants under the code?
    A. A single bedroom?
    Q. Yes. A one-bedroom can have two occupants per—they’re large enough
    to—under the code to have two residents per single bedroom; correct?
    A. I believe that is correct. I don’t have the square footage in front of me for
    that building. Every one of our communities is designed by a different—necessarily
    a different architect and have different square footages of the room.
    We do have to follow the minimum code that’s provided under the
    administrative code. And, as you stated, a studio has to be a minimum of 300 and
    *** 450 for a double occupied.
    ***
    Q. *** I just want to—This is an important point that I want to establish,
    that one-bedrooms are 506 square feet? I’m showing you what—I’ve handed you a
    floor plan for the one-bedroom unit.
    A. Okay.
    Q. Isn’t it true that 23 by 22 is the dimensions shown?
    A. According to this, yes.
    Q. And that would be a 506-square-foot unit?
    A. I agree with you.”
    7
    ¶ 19          Further, Mitchell confirmed, as depicted on the Department’s schedule, a supportive living
    facility receives approximately $106 per Medicaid-eligible resident from SNAP. Likewise, a
    supportive living facility receives approximately $2171 per Medicaid-eligible resident from
    Medicaid. This is the maximum amount received per Medicaid-eligible resident for services,
    calculated using 60% of the nursing home rates compiled from cost reports. Mitchell believed this
    rate was per diem based on income levels and costs of services in the region. Mitchell disagreed
    that there was a capital component, estimating value based on real estate, to the Medicaid rate. In
    total, the Department’s schedule estimated the monthly revenue of a supportive living facility from
    a Medicaid-eligible resident was $2897 in 2013 ($620 + $106 + $2171).
    ¶ 20          In rebuttal, Mitchell stated the potential gross income of a supportive living facility is
    calculated by the number of units times the rent amount plus a vacancy factor, rather than by the
    capacity of the building times a rent amount.
    ¶ 21                                           2. Keith Honegger
    ¶ 22          Honegger was hired by DSI to complete an appraisal of Heritage Woods as of January 1,
    2013. Honegger is a certified general real estate appraiser, but he is not a member of the Appraisal
    Institute and he has not completed 3000 hours of peer-reviewed work or a demonstrative appraisal
    of a complex property.
    ¶ 23          Honegger testified that he could have labeled his report an appraisal report rather than a
    restricted use report. Regardless, Honegger stated it is unclear whether a restricted use report can
    be used by more persons than just the client. Honegger explained that, in this case, the report was
    restricted because he did not want the appraisal report to be used for a market value sale.
    ¶ 24          Honegger calculated the fair cash value of Heritage Woods under section 10-390’s income
    capitalization approach, which he believed required the use of actual rental income. As such,
    8
    Honegger calculated potential gross income from room and board using the Department’s
    schedule’s mandated $620 rate for the 37 studio and 44 one-bedroom apartments. Honegger used
    the Department’s schedule’s mandated $886 room and board rate for the 6 two-bedroom
    apartments. Honegger concluded Heritage Woods’s potential gross income from room and board
    totaled $666,432 (($620 x 37 single-occupancy, studio units) + ($620 x 44 single-occupancy, one-
    bedroom units) + ($886 x 6 double-occupancy, two-bedroom units) x 12 months).
    ¶ 25          However, Honegger testified that potential gross income from room and board includes
    food costs. To calculate only potential gross rental income, Honegger subtracted food costs before
    adding SNAP revenue. In 2012, the food costs at Heritage Woods were $139,444. The SNAP
    revenue at Heritage Woods totaled $68,816 in 2012. Using the maximum, full occupancy, potential
    gross income of Heritage Woods in 2012 ($656,592), Honegger calculated the potential gross
    rental income at Heritage Woods in the amount of $585,964 (($656,592 - $139,444) + $68,816).
    With a vacancy rate of less than 1%, Honegger opined effective gross rental income at Heritage
    Woods totaled $580,964.
    ¶ 26          Next, Honegger calculated the operating expenses of Heritage Woods. Honegger testified
    that a supportive living facility’s operating expenses are commingled between rent and services,
    so there is no way to individually subtract the expenses for rent under section 10-390 of the
    Property Tax Code. However, Honegger developed a method for estimating the operating expenses
    of Heritage Woods by comparing supportive living facilities to properties financed under section
    42 of the Internal Revenue Code, 
    26 U.S.C. § 42
     (2012).
    ¶ 27          Honegger explained that there are 118 supportive living facilities outside of Cook County,
    26% of which have living portions financed by section 42. Honegger believed observing the
    expense ratios of 14 “strict” section 42 properties, which do not provide services, would allow him
    9
    to predict the expense ratios of section 42 properties with supportive living components.
    Supportive living facilities operate identically, so a “living portion [of a supportive living facility]
    that’s not a Section 42 [property] would *** have a similar expense ratio.”
    ¶ 28          After reviewing the data, Honegger concluded the 14 “strict” section 42 properties had, on
    average, a 68.6% expense ratio. Two “strict” section 42 properties that were “most comparable”
    to Heritage Woods had a 63.4% expense ratio on average. Honegger concluded from this data that
    Heritage Woods would have an expense ratio between 61% and 65.7%.
    ¶ 29          Moreover, Honegger reviewed data from 17 other supportive living facilities managed in
    Illinois by Gardant. The operating expenses of those properties ranged from 46.5% to 79.5%.
    However, the average expense ratio was 61% and 62% in 2011 and 2012, respectively. Honegger
    noted that these percentages closely aligned with the 63.4% average expense ratio of the “most
    comparable” “strict” section 42 properties. Therefore, the data indicated “the expense side of [a
    supportive living facility] for services is similar to the expense side *** for rent.”
    ¶ 30          Ultimately, Honegger concluded that the lower end of the range of data was most
    appropriate for Heritage Woods. As a result, Honegger used a 61% expense ratio to calculate net
    income. Initially, Honegger multiplied the expense ratio (61%) by effective gross rental income
    ($580,964) to calculate the operating expenses of Heritage Woods at $354,388. Honegger then
    subtracted operating expenses ($354,388) from effective gross rental income ($580,964) to
    calculate the net operating income of Heritage Woods at $226,576. Applying a capitalization rate
    of 0.111, Honegger concluded that the fair cash value of Heritage Woods under the income
    capitalization approach was $2,041,225 ($226,576 / 0.111) as of January 1, 2013.
    ¶ 31          On cross-examination, Honegger was asked about the Department’s $620 room and board
    rate applying to all occupants of studio and one-bedroom apartments, despite the differences in
    10
    size of those apartments. Honegger did not believe he had to reconcile these differences in size as
    part of his analysis of the fair cash value of Heritage Woods. Honegger stated, based upon the
    information he was given by DSI, the $620 room and board rate applied to both studio and one-
    bedroom apartments.
    ¶ 32          Similarly, Honegger stated, based upon the information he was given by DSI, the two-
    bedroom apartments were the only double-occupancy units at Heritage Woods. However,
    Honegger agreed that the maximum occupancy of Heritage Woods was 137 residents. Thus, it had
    to be possible for a one-bedroom apartment to house two occupants for a potential gross income
    of $886 per month, rather than house one occupant for a potential gross income of $620 per month.
    By extension, Honegger agreed that, under his methodology, Heritage Woods could gross a
    potential income of $806,880 (($620 x 37 single-occupancy, studio units) + ($886 x 44 double-
    occupancy, one-bedroom units) + ($886 x 6 double-occupancy, two-bedroom units) x 12 months).
    ¶ 33          When questioned by the hearing officer, Honegger confirmed his belief that actual rents,
    i.e., the room and board rates stated on the Department’s schedule, rather than market rents, must
    be used to value supportive living facilities. This was because the law “forc[es] these people to
    have a rent that’s below market *** [and] that’s what the property produces economically.”
    ¶ 34                                          3. Michael MaRous
    ¶ 35          MaRous is a certified general real estate appraiser who was hired by the School District to
    complete an appraisal of Heritage Woods as of January 1, 2013. MaRous is a member of the
    Appraisal Institute and has appraised real estate for over 40 years, lectured in various appraisal
    settings, published articles, and has been cited in approximately 15 books on appraising.
    ¶ 36          As part of his appraisal, MaRous emphasized the income capitalization approach, required
    by section 10-390 of the Property Tax Code, but used the sales comparison approach as a check.
    11
    To estimate potential gross rental income, MaRous considered Heritage Woods’s asking rents of
    $3425 for a studio apartment; $3750 for a one-bedroom, single-occupancy, apartment; $4550 for
    a one-bedroom, double-occupancy, apartment; $4850 for a two-bedroom, single-occupancy,
    apartment; and, $5150 for a two-bedroom, double-occupancy, apartment. MaRous opined that
    there was a $325 difference in the asking rent of a studio apartment and a one-bedroom, single-
    occupancy, apartment due to “the benefit of having the bigger apartment.” MaRous attempted to
    segregate the value of real estate from services by grossing the income and deducting the service
    costs.
    ¶ 37            Moreover, MaRous considered (1) the rents of five comparable properties, which were
    identified as independent or assisted living but not supportive living facilities, (2) past rent levels
    at Heritage Woods, (3) market surveys and trends, and (4) “the fact that 50, 55 percent of the
    subject [facility’s population] is generally Medicaid[-eligible].” MaRous considered the
    Department’s schedule for Medicaid-eligible residents, but, in his view, the stated room and board
    rates depicted allocated rates that did not account for geographic location. Thus, asking rents were
    more applicable to the market value of the real estate. Asking rents included “goods and services
    that [we]re not related to *** real estate,” but “nonreality sources of rental income [were] offset
    by the expenses of these goods and services.”
    ¶ 38            Ultimately, MaRous stabilized the market rental rates of Heritage Woods to develop
    potential gross income. He used $2900 for the 37 studio apartments, $3500 for the 44 one-bedroom
    apartments, and $3700 for the 6 two-bedroom apartments, yielding a stabilized rental income of
    $3,402,000 (($2900 x 37 studio apartments) + ($3500 x 44 one-bedroom apartments) + ($3700 x
    6 two-bedroom apartments) x 12 months). MaRous found Heritage Woods had occupancy rates of
    12
    99.5% in 2009, 99.6% in 2010, 99% in 2011, and 98.7% in 2012, so he used a 2.5% vacancy rate
    to calculate Heritage Woods’s effective gross rental income at $3,316,950.
    ¶ 39          Next, MaRous testified to Heritage Woods’s operating expenses. MaRous generated
    stabilized operating expenses with data from Heritage Woods’s comparative income statements
    between 2010 and 2012. From his review of this data and the exclusion of nonrealty expenses for
    goods and services, MaRous concluded that 83.5% was an appropriate expense ratio to calculate
    net operating income. MaRous multiplied this expense ratio by effective gross rental income
    ($3,316,950) to calculate the operating expenses of Heritage Woods at $2,768,650. 2 MaRous then
    subtracted operating expenses ($2,768,650) from effective gross rental income ($3,316,950) to
    calculate Heritage Woods’s net operating income at $548,300. MaRous confirmed his belief that
    this figure excluded income for services. Applying a capitalization rate of 0.1067, derived from
    RealtyRates.com, a band of investments technique, and the addition of a real estate tax load,
    MaRous concluded the fair cash value of Heritage Woods under the income capitalization
    approach was approximately $5,138,707 ($548,300 / 0.1067) as of January 1, 2013. MaRous
    reconciled this calculation with his calculations under the sales comparison approach, then finally
    concluded Heritage Woods had a fair cash value of $5,150,000 as of January 1, 2013.
    ¶ 40          On cross-examination, MaRous said he considered Heritage Woods to be an assisted living
    facility, but that it could also be considered a supportive living facility. MaRous indicated that
    Medicaid assistance was the only primary difference between the two types of facilities.
    ¶ 41          Further, MaRous restated his belief that he excluded income from services when valuing
    Heritage Woods under the income capitalization approach. MaRous said he grossed up the income
    and took out all the expenses allocated to both real estate and service income. MaRous agreed that
    2
    We note that 83.5% of $3,316,950 is actually $2,769,653.25.
    13
    although he did not deduct service income from potential gross income, he deducted service
    income from operating expenses. MaRous then stabilized operating expenses with three years of
    operating expenses from Heritage Woods. MaRous believed this complied with section 10-390 of
    the Property Tax Code because he removed all the expenses attributable to services.
    ¶ 42          However, when asked by the hearing officer if he “really allocated out just the services
    portion,” MaRous said “[n]o[,] I wasn’t able to because of the way these things are run.” Likewise,
    on redirect examination, MaRous was asked “does your net operating income before deduction for
    real estate taxes include income for services?” MaRous responded, “[g]enerally not, but it does
    include [services] for food *** [a]nd basic services within the monthly package.” MaRous also
    agreed if a Medicaid-eligible resident receives more than $620, then the excess funds reduce the
    services paid by Medicaid and are not kept by a supportive living facility.
    ¶ 43                                                4. Eric Dost
    ¶ 44          Dost is a certified general real estate appraiser who was hired by the School District to
    review Honegger’s appraisal of Heritage Woods. Dost is a member of the Appraisal Institute who,
    in his career, has conducted between 200 and 300 review appraisals.
    ¶ 45          Initially, Dost stated Honegger’s report was a restricted use report, which is intended for a
    single user, the client. According to Dost, if there are other users, such as a local board or the
    PTAB, then it is improper to complete a restricted use report instead of an appraisal report. The
    level of detail is the difference between the two types of reports. Dost said Honegger omitted
    certain sections that would be included in an appraisal report, but admitted that, in theory, a
    restricted use report does not result in a different fair cash value than an appraisal report.
    ¶ 46          Dost also recognized that section 10-390 of the Property Tax Code requires valuations
    under the income capitalization approach. He did not believe the Department’s schedule for room
    14
    and board, utilized by Honegger, reflected market rates of supportive living facilities. Dost opined
    that Heritage Woods was “getting higher rents for its private pay rates.” Further, Dost testified that
    the Medicaid rate on the Department’s schedule is derived from 60 percent of the average nursing
    facility Medicaid rate within the region and is a compilation of costs with a nursing component,
    support services component, and capital component. He believed the Department’s schedule for
    Medicaid rates included real estate and services because a capital component is built into that cost
    and the supportive living portion that includes real estate.
    ¶ 47          Dost stated that Honegger’s appraisal failed to account for sources of revenue at Heritage
    Woods, including income from the beauty salon and the convenience store. Regarding operating
    expenses, Honegger’s analysis appeared to be based largely on overall expense ratios of section
    42 properties, when traditionally this analysis would include itemizing individual categories of
    expenses. Dost did not know the occupancy rates or rent restrictions of Honegger’s section 42
    properties, which Dost said could be skewing operating expenses. Honegger’s calculations could
    also be skewed by below average revenues and above average costs.
    ¶ 48          When asked about calculating potential gross income with Heritage Woods’s maximum
    occupancy of 137 residents, Dost said he would consider the percentage of occupied units and the
    licensed capacity. Dost stated it really comes down to how a second resident of an apartment is
    treated. Ultimately, Dost concluded that Honegger’s report was not credible or reliable.
    ¶ 49                                        B. Decision of the PTAB
    ¶ 50          On June 19, 2018, the PTAB issued a detailed decision to the parties, finding “the
    preponderance of the evidence *** indicate[d] a reduction in the *** assessment [of Heritage
    Woods] [w]as warranted.” The PTAB relied primarily on the appraisals and testimony of
    Honegger and MaRous, recognizing that they agreed on the basic methodologies for valuing
    15
    supportive living facilities under section 10-390’s income capitalization approach. Indeed, the
    PTAB noted it was undisputed that this approach required the appraisers to “derive a value
    indication for [the] income-producing property by converting its anticipated benefits *** into
    property value.” This is done by “convert[ing] one year’s income expectancy (potential gross
    operating income less operating expenses) by applying a market-derived capitalization rate.”
    ¶ 51          However, the PTAB also acknowledged that there were “extreme divergent opinions”
    between Honegger and MaRous. Therefore, the PTAB found it was “appropriate to examine the
    data and compute” the fair cash value of Heritage Woods under the income capitalization approach
    required by section 10-390, “using proper rents[,] which exclude income and expense[s] from
    services[,] and the appropriate rate of estimated vacancy.”
    ¶ 52          With respect to potential gross rental income, the PTAB found Honegger’s calculation of
    $585,964, derived from the actual rents of Heritage Woods in 2012, $656,592, was “better
    supported” than that of MaRous. With respect to MaRous’s comparables, the PTAB found:
    “MaRous incorrectly lumped supportive living, assisted living, independent
    living and senior living facilities together. The testimony revealed he considered
    them to be the same, however, technically, for purposes of his appraisal he testified
    he should have called them supportive living facilities. The testimony depicts the
    latter two are not Medicaid certified facilities, offer different amenities, have
    different layouts, and obtain different market rents based on private pay residents.
    The record further depicts [Heritage Woods], as a supportive living facility, has
    monthly rent that is dictated by the Illinois Supportive Living [Facilities] Program
    as shown by [the Department’s schedule].”
    16
    From these findings, the PTAB concluded that MaRous “grossly overstated [Heritage Woods]’s
    estimated potential gross income based on the comparables used to stabilize *** rental income.”
    In the absence of market comparables and in light of the “unique characteristics, mandates and
    rental restraints of” supportive living facilities, the PTAB found Heritage Woods’s “actual rents”
    were “more indicative of market rents than the market rents developed by MaRous.”
    ¶ 53          Even though Honegger’s estimate was “better supported,” the PTAB found he should have
    included income from the incidental amenities, such as the beauty salon and the convenience store.
    With these additions, plus SNAP revenues and minus food costs, the PTAB concluded the potential
    gross income of Heritage Woods was $605,337. After considering the occupancy rates used by
    Honegger and MaRous, the PTAB found a 1% vacancy rate was reasonable to calculate effective
    gross income. Using this vacancy rate, the PTAB found the effective gross operating income of
    Heritage Woods, when rounded, was $600,000.
    ¶ 54          With respect to operating expenses, the PTAB prefaced its findings by stating it agreed that
    “the expenses for a supportive living facility are commingled and intertwined among the various
    services offered by the facility, making it difficult *** to allocate out expenses for services,” as
    required by section 10-390. Nevertheless, the PTAB found Honegger’s method for calculating
    operating expenses, based upon an examination of section 42 properties, was “credible, verifiable
    and better supported through the testimony.”
    ¶ 55          Conversely, the PTAB rejected MaRous’s conclusions on operating expenses, which were
    derived from the stabilized operating expenses of Heritage Woods between 2010 and 2012. The
    PTAB noted that MaRous “grossed up the income and took out all expenses allocated to both real
    estate and service income.” However, the PTAB found “this method was questionable” because,
    during cross-examination, “MaRous was unable to indicate where he deducted service income and
    17
    where he excluded service expense.” Further, when asked whether his net operating income
    included income for services, MaRous testified “[g]enerally not, but it does include [services] for
    food *** [a]nd basic services within the monthly package.” Thus, the PTAB found “the method
    developed by MaRous [wa]s not credible because he could not definitively state nor verify with
    certainty that his calculations did not include service income.” The PTAB applied the 61% expense
    ratio derived by Honegger to its $600,000 effective gross operating income to calculate operating
    expenses at $366,000 ($600,000 x .61).
    ¶ 56          Regarding the capitalization rate, the PTAB found Honegger and MaRous were “fairly in
    agreement.” Honegger derived a capitalization rate of 0.111 and MaRous derived a capitalization
    rate of 0.1067. Based upon the evidence, the PTAB concluded “an overall loaded capitalization
    rate” of 0.1085 was “well supported.”
    ¶ 57          From these calculations, the PTAB concluded Heritage Woods had a 2013 fair cash value
    of $2,156,682 under section 10-390’s income capitalization approach. To arrive at this figure, the
    PTAB calculated the net operating income of Heritage Woods by subtracting operating expenses
    ($366,000) from effective gross operating income ($600,000) for a total of $234,000. The PTAB
    then divided net operating income ($234,000) by the capitalization rate (0.1085), which yielded a
    fair cash value of $2,156,682. Next, under section 1-55, the PTAB multiplied Kankakee County’s
    “three-year median level of assessments” (33.11%) by the fair cash value of Heritage Woods
    ($2,156,682) to reduce that property’s 2013 tax assessment from $1,688,165 to $714,077.
    ¶ 58          On June 21, 2018, the School District filed a timely petition for direct review of the PTAB’s
    decision under Illinois Supreme Court Rule 335(a) (eff. July 1, 2017), section 16-195 of the
    Property Tax Code, 35 ILCS 200/16-195 (West 2012), and section 1910.74(a)(2) of Title 86 of the
    Administrative Code, 86 Ill. Adm. Code 1910.74(a)(2) (2000).

    ¶ 59                                             II. ANALYSIS
    ¶ 60          In this appeal, our direct review is governed by the Administrative Review Law (735 ILCS
    5/3-101 et seq. (West 2016)) and may “extend to all questions of law and fact presented by the
    entire record.” 
    Id.
     § 3-110; see Kankakee County Board of Review v. Property Tax Appeal Board,
    
    337 Ill. App. 3d 1070
    , 1074 (2003) (Kankakee County I). Broadly construed, the School District
    challenges the PTAB’s reduction of Heritage Woods’s 2013 property tax assessment on two
    alternative bases. First, the School District asserts that the PTAB’s decision was based upon an
    incorrect method for applying the income capitalization approach required by section 10-390.
    Second, the School District argues that the PTAB’s decision was arbitrary and capricious.
    ¶ 61          The logical starting point for our analysis is to begin with a summary of the applicable
    statutes that govern real estate valuation for purposes of taxation. Typically, under section 1-50 of
    the Property Tax Code, 35 ILCS 200/1-50 (West 2012), “[f]air cash value” for purposes of a tax
    assessment is defined as “[t]he amount for which a property can be sold in the due course of
    business and trade, not under duress, between a willing buyer and a willing seller.”
    ¶ 62          In the context of section 1-50, “fair cash value” is synonymous with “fair market value”
    and “an arm’s-length sales transaction is the best evidence thereof.” Kraft Foods, Inc. v. Illinois

    2013 IL App (2d) 121031
    , ¶ 43.
    ¶ 63          However, our legislature expressly adopted the “income capitalization approach” for
    purposes of determining “the fair cash value of any supportive living facility.” 35 ILCS 200/10-

    00693.pdf [https://perma.cc/7LYN-XDYA] (PTAB finding “the provisions of Section 10-390 are
    not couched in terms of determining traditional fair market value, but rather [in] *** using a
    unique, different and non-traditional appraisal analysis utilizing a modified income capitalization
    approach to value”). An appraiser may not consider income in the form of “payments from
    Medicaid for services provided to residents *** when such payments constitute income that is
    attributable to services and not attributable to the real estate.” 35 ILCS 200/10-390(b)(1) (West
    2012). Likewise, an appraiser may not consider “payments by a resident *** for services that
    would be paid by Medicaid if the resident were Medicaid-eligible, when such payments constitute
    income that is attributable to services and not attributable to real estate.” See 
    id.
     § 10-390(b)(2).
    The assessment at issue pertains to a supportive living facility and requires our consideration of
    section 10-390.
    ¶ 64                                         A. Standard of Review
    ¶ 65          Initially, the parties disagree on the standard of review. The School District argues both
    contentions of error should be reviewed de novo, since they involve questions of law and statutory
    interpretation. Conversely, the PTAB asserts our review must be deferential and based upon the
    manifest weight of the evidence standard. As support for this assertion, the PTAB contends that
    the appropriate valuation method is undisputed and our review is restricted to the PTAB’s
    acceptance of Honegger’s, and not MaRous’s, application of the income capitalization approach.
    DSI has not requested a specific standard but indicates de novo review is appropriate.
    ¶ 66          It is well accepted that administrative review proceedings may present questions of law,
    fact, or law and fact. John J. Moroney & Co. v. Illinois Property Tax Appeal Board, 
    2013 IL App (1st) 120493
    , ¶ 36. The PTAB’s findings on questions of law are reviewed de novo, “ ‘rendering

    Property Tax Appeal Board, 
    403 Ill. App. 3d 139
    , 143 (2010). It is notable that our supreme court,
    while not in the context of section 10-390, found a question involving the proper method for
    employing the income capitalization approach was one of law. See Kankakee County Board of
    Review v. Property Tax Appeal Board, 
    131 Ill. 2d 1
    , 6, 14-15 (1989) (Kankakee County II).
    ¶ 67           The PTAB’s findings on questions of fact are “held to be prima facie true and correct.”
    735 ILCS 5/3-110 (West 2016). It is not the role of a reviewing court to “reweigh the evidence,
    reassess the credibility of the witnesses, substitute its judgment for that of the PTAB, or make an
    independent determination of the facts,” as these jobs are uniquely within the province of the
    PTAB. Kraft Foods, 
    2013 IL App (2d) 121031
    , ¶ 51; National City Bank of Michigan/Illinois v.
    Property Tax Appeal Board, 
    331 Ill. App. 3d 1038
    , 1042-43 (2002). The PTAB’s findings on
    questions of fact are disturbed only if against the manifest weight of the evidence, meaning all
    reasonable and unbiased persons would agree the decision is erroneous and an opposite conclusion
    is clearly evident. 3 Kankakee County I, 337 Ill. App. 3d at 1074.
    ¶ 68           In the context of reviewing whether the PTAB’s reduction of a property tax assessment
    should be upheld or set aside, our supreme court has stated that a reviewing court is “not charged
    with the responsibility of determining the [fair cash value] of the subject property.” Kankakee
    County Board of Review v. Property Tax Appeal Board, 
    226 Ill. 2d 36
    , 50 (2007) (Kankakee
    County III). Our court simply decides whether the PTAB’s decision to reduce the property tax
    assessment was correct, a question that turns on “whether petitioner employed a proper valuation
    method.” 
    Id.
     As stated in Kankakee County III, such a review is de novo. 
    Id. at 51
    . The present
    3
    None of the parties argue that this appeal involves a mixed question of law and fact, necessitating
    a review for clear error. See Moroney, 
    2013 IL App (1st) 120493
    , ¶ 36. We agree because the historical
    facts are not admitted or clearly established as to make the issue whether those facts satisfy an undisputed
    rule of law. See Exelon Corp. v. Department of Revenue, 
    234 Ill. 2d 266
    , 273 (2009).
    21
    appeal turns on this precise question, so we conduct an “ ‘ “independent and not deferential” ’ ”
    de novo review. See Cook County Board, 403 Ill. App. 3d at 143; Kankakee County III, 
    226 Ill. 2d at 50-51
    ; see also Kankakee County II, 
    131 Ill. 2d at 6, 14-15

    2013 IL App (2d) 121031
    , ¶¶ 42, 44.
    ¶ 69          Nonetheless, we recognize that the PTAB has an abundance of expertise and familiarity
    with the complex issues arising from property taxation. Further, we would be remiss if we did not
    acknowledge the PTAB’s 25-page written decision was very thorough. In fact, the PTAB’s
    decision included a comprehensive recitation of the testimony and evidence presented at the
    administrative hearing, which was helpful to this court. However, since our review is restricted to
    examining the valuation methodology alone, it is not necessary to “delve into the minutiae of
    expert testimony or make credibility determinations.” See Pappas, 
    2018 IL App (1st) 162714
    ,
    ¶ 64. Therefore, we conclude the manifest weight of the evidence standard does not apply. Even if
    it did, that deferential standard of review would not change the outcome of this appeal, as discussed
    below. We now turn our attention to the School District’s contentions of error.
    ¶ 70                   B. Method for Calculating Fair Cash Value Under Section 10-390
    ¶ 71          The School District contends that the evidence presented by DSI to the PTAB was gathered
    by means of an inherently flawed methodology with respect to income capitalization. According
    to the School District, the PTAB improperly granted a reduction in the assessment by considering
    the amount of actual income DSI attributes to rent in its business records, rather than the potential
    capacity for Heritage Woods to receive rental income. The School District alleges that the flawed
    methodology resulted in an artificially low fair cash value for Heritage Woods.
    ¶ 72          DSI disagrees and submits that this court should conclude the PTAB’s approach to income
    capitalization was correct. According to DSI, the actual rental income and the potential capacity
    22
    for rental income at Heritage Woods were the same amount. As support, DSI asserts it could not
    “charge its tenants more than the published allowances by the Department[’s]” schedule. Thus, the
    Department’s room and board rates “are to be used in calculating income.” For the reasons
    discussed below, we find DSI’s view is oversimplistic and legally incorrect.
    ¶ 73          In Kankakee County II, our supreme court discussed how, in some situations, “actual rental
    income” is not the correct measure of a property’s capacity to generate income. See Kankakee
    County II, 
    131 Ill. 2d at 15-16
    . This is such a situation for Heritage Woods.
    ¶ 74          In Kankakee County II, our supreme court found:
    “When actual rental income does not reflect the income-earning capacity of property, it
    may be disregarded, and the taxing authority may look to rents obtainable for comparable
    property in the open market. Where actual income truly reflects the income-earning
    capacity of the property, however, it may not be ignored simply because it does not
    coincide with rents obtainable on the open market.” 
    Id.
     See also Town of Cunningham v.
    Property Tax Appeal Board, 
    225 Ill. App. 3d 760
    , 765 (1992) (Kankakee County II, while
    based on “government subsidized housing,” “discusses basic legal principles of property
    valuation.”).
    To be even more clear, our supreme court emphasized, “it is the capacity for earning income, rather
    than the income actually derived, which reflects “fair cash value” for taxation purposes.’ ”
    Kankakee County II, 
    131 Ill. 2d at 17
     (quoting Springfield Marine Bank v. Property Tax Appeal
    Board, 
    44 Ill. 2d 428
    , 431 (1970)); see also Lake County Board of Review v. Property Tax Appeal
    Board, 
    172 Ill. App. 3d 851
    , 856-57 (1988) (finding it improper to “disregard the contract rent”
    where that contract rent reflected “the complex’s capacity to earn income”).
    23
    ¶ 75          Initially, we note that Heritage Woods has 87 total units. When calculating Heritage
    Woods’s potential gross income from those units, Honegger ignored the potential for Heritage
    Woods to receive real estate income based on the double-occupancy of some one-bedroom units.
    Therefore, we agree with the School District’s observation that Heritage Woods’s potential gross
    income should not have been based on an assumption that all income generated from its 44 one-
    bedroom units was limited to the amount of rent paid by a single occupant of each unit.
    ¶ 76          For example, when asked if it was “true that each of [Heritage Woods’s] single bedrooms
    are code certified double [occupancy],” Mitchell answered, “I believe that is correct.” This was
    because he agreed the minimum square footage for double-occupancy units is 450 square feet and
    one-bedroom units at Heritage Woods are 506 square feet. Rather than accounting for a reasonable
    number of double-occupancy one-bedroom units when calculating potential gross income,
    Honegger based his analysis on an assumption that actual rent was only paid as follows: $620 for
    the 37 studio units; $620 for the 44 one-bedroom units; and, $886 for the 6 two-bedroom units.
    Even if rental income from double-occupancy one-bedroom units is rare or minimal, the capacity
    to earn a reasonable amount of this additional real estate income was ignored by Honegger for
    purposes of Heritage Woods’s fair cash value. This resulted in a flawed methodology under the
    income capitalization approach. See Kankakee County II, 
    131 Ill. 2d at 15-17
    .
    ¶ 77          As importantly, Heritage Woods serves more than just Medicaid-eligible, low-income
    residents, who are charged the Department’s fixed fates. The record indicates Heritage Woods
    housed approximately 50-55% Medicaid-eligible residents and 45-50% private-pay residents
    during the relevant timeframe.
    ¶ 78          DSI claims on appeal that it charges all residents a fixed room and board rate because it
    could not “charge its tenants more than the published allowances by the Department[’s]”
    24
    schedule.” Curiously, DSI has not directed our attention to the authority for this assertion. In fact,
    section 146.215(d) of Title 89 of the Administrative Code belies DSI’s statement that private-pay
    residents must be charged the Department’s fixed rate. See 89 Ill. Adm. Code 146.215(d) (2020).
    That section states “[i]f the [Supportive Living Program] provider charges a private-pay rate higher
    than the Medicaid rate,” then “not less than” 25% of the facility shall be reserved for Medicaid-
    eligible persons. 
    Id.
     4 Contrary to DSI’s position, this language reveals that DSI could lawfully
    charge a private-pay resident a rental rate higher than the fixed rate for Medicaid-eligible residents.
    ¶ 79           Despite the fact that DSI purports to charge all residents the same amount for room and
    board, the record indicates the package prices actually paid by Medicaid-eligible and private-pay
    residents are not the same. As discussed below, DSI charges private-pay residents higher prices
    than low-income Medicaid-eligible residents for the same square footage and the same services. If
    the excess income DSI receives from private-pay residents is not entirely comprised of purely
    service-related income, then the PTAB’s decision must be reversed. Next, we consider the nature
    of the excess income collected by DSI from private-pay residents each month.
    ¶ 80           DSI’s own witness, Mitchell, admitted that some private-pay residents are charged “more
    for the exact same services because [he or she] live[s] in a bigger room.” (Emphases added.)
    According to Mitchell, the excess combined room and board and service income that DSI receives

    We note the full text of section 146.215(d) of Title 89, which permits a supportive living facility
    to house up to 75% private-pay residents, states: “The [Supportive Living Program] provider shall accept
    the SSI rate (less the personal allowance) for room and board for Medicaid residents. If the [Supportive
    Living Program] provider charges a private pay rate higher than the Medicaid rate, the [Supportive Living
    Program] provider shall reserve not less than 25 percent of its apartments for Medicaid-eligible residents.
    Those [Supportive Living Program] settings that set a commensurate rate for both private pay and
    Medicaid-eligible residents are not required to reserve apartments for Medicaid-eligible residents but must
    accept Medicaid-eligible residents on a first come, first served basis.” See 89 Ill. Adm. Code 146.215(d)
    (2020).

    particular apartment. That is, the excess income from private-pay residents is attributable to the
    differences between DSI’s asking prices for studio and one-bedroom apartments ($325) and
    double-occupancy one-bedroom and double-occupancy two-bedroom apartments ($600). Hence,
    based on Mitchell’s testimony alone, it is clear that DSI is receiving some amount of income
    attributable to real estate that DSI inaccurately reported to Honegger as excludable income
    attributable to services.
    ¶ 81           Mitchell’s testimony leads to one conclusion. Namely, the restricted use appraisal the
    PTAB received from Honegger was predicated on DSI’s understated numbers for real estate
    income, together with excludable, but overstated, numbers for service income DSI collects from
    private-pay residents. In other words, as Mitchell agreed, there is an income component from real
    estate, based on the size of the living space, that is labeled entirely as excludable service income
    by DSI. Thus, Honegger’s restricted use appraisal may have reflected DSI’s bookkeeping practices
    but it did not “truly reflect[ ] the income-earning capacity” of Heritage Woods, as discussed by
    our supreme court in Kankakee II. See Kankakee County II, 
    131 Ill. 2d at 15-17
    . Consequently,
    Honegger’s calculation of fair cash value cannot be described as “more probably true than not
    true,” as was required for DSI to meet the preponderance of the evidence burden of proof. See
    Avery v. State Farm Mutual Automobile Insurance Co., 
    216 Ill. 2d 100
    , 191 (2005); National City
    Bank, 331 Ill. App. 3d at 1042; 86 Ill. Adm. Code 1910.63(a), (b), (e) (2000).
    ¶ 82           We acknowledge, generally, that Kankakee County II indicates that, under the right
    circumstances, the actual rents mandated by the Department may be the best measure of income
    earning capacity under section 10-390. See Kankakee County II, 
    131 Ill. 2d at 15-17
    . This approach
    accurately measured Heritage Woods’s income earning capacity for the approximately 50-55%
    Medicaid-eligible residents.
    26
    ¶ 83           We also acknowledge that the PTAB has allowed the use of those actual rents in more
    recent decisions, which were decided after the reduction of Heritage Woods’s property tax
    assessment. See Prairie Winds of Urbana, LP, Ill. Prop. Tax App. Bd. No. 15-00068.001-C-3, at
    10, 27 (July 17, 2018), http://www.ptab.illinois.gov/web/Decisions/2015/2015-00068.pdf
    [https://perma.cc/6VSL-KY23] (PTAB reducing a subject property’s assessment “to reflect the
    Honegger appraisal report,” which had an “income figure [that] was drawn from *** actual [rental]
    income”); Petersen Health Systems, Inc., Ill. Prop. Tax App. Bd. No. 15-00693.001-C-2, at 19-20
    (PTAB reducing a subject property’s assessment “commensurate with the appellant’s evidence,”
    which was “solely *** [based] upon the published [Department] regional allocation for Medicaid
    residents at supportive living facilities”).
    ¶ 84           Nonetheless, measuring income earning capacity based on the purported amount of actual
    rent charged on-the-books at Heritage Woods was not a true measure of the amount of rental
    income mislabeled by DSI as service income. While the Department’s fixed rate for Medicaid-
    eligible residents governs as the highest amount DSI may charge those Medicaid-eligible residents
    for room and board, there is no similar restriction on the lowest amount DSI may charge private-
    pay residents for room and board. If the PTAB’s decision were to stand, nothing would prevent
    DSI from further reducing its actual rents charged to all residents, thereby allowing DSI’s
    bookkeeping to dictate fair cash value. Surely, this was not the legislative intent for section 10-
    390’s income capitalization approach. Since DSI elected to present inaccurate evidence of the
    actual rental income being paid by private-pay residents, under the guise of service income, the
    PTAB’s decision was not based on an accurate measure of rental income flowing from Heritage
    Woods’s residents to DSI.
    27
    ¶ 85          Putting the occupancy issue aside, the PTAB’s decision regarding the fair cash value of
    Heritage Woods would be correct if the facility was 100% occupied by Medicaid-eligible low-
    income residents. However, the record indicates that approximately 45-50% of Heritage Woods’s
    residents were private-pay individuals paying higher prices for the same services and the benefit
    of having a larger apartment. Here, under section 10-390’s income capitalization approach,
    Heritage Woods’s fair cash value should have been based on an amount no less than the income
    earning capacity attributable to the approximately 50-55% Medicaid-eligible residents, where the
    market rate and the actual rate were the same under the Department’s schedule. In addition, the
    fair cash value of Heritage Woods should have been based on the added true capacity to earn real
    estate income from the remaining percentage of higher income residents. The capacity to earn real
    estate income from private-pay residents should have been, but was not, calculated based on the
    comparable market rate DSI could have received from private-pay residents who were not
    Medicaid-eligible. Thus, the actual rents DSI claimed to charge should have been disregarded
    because they did not “truly reflect[ ] the income-earning capacity of the property.” See Kankakee
    County II, 
    131 Ill. 2d at 15-17
    .
    ¶ 86          The PTAB and DSI have requested that our court comment on the veracity of MaRous’s
    valuation methodologies and opinions before remanding the matter with directions for the PTAB
    to enter a decision consistent with this opinion. To clarify, we have not disturbed the PTAB’s
    finding that MaRous’s valuation methodologies and opinions were flawed and unreliable.
    ¶ 87          Now, for reasons discussed at length in this opinion, we have reached a similar conclusion
    that Honegger’s valuation methodologies and opinions were flawed and unreliable due to the
    understated real estate income from private pay residents and the assumption that one-bedroom
    units at Heritage Woods do not have the capacity to generate real estate income from two
    28
    occupants. As stated above, DSI did not sustain its burden of proof with Honegger’s restricted use
    appraisal, which was based on a flawed method for applying the income capitalization approach
    to fair cash value. See 86 Ill. Adm. Code 1910.63(a), (b), (e) (2000).
    ¶ 88          Accordingly, a remand is not warranted because the existing record contains only
    unreliable opinions based on flawed methodologies from Honegger and MaRous, resulting in
    legally erroneous approaches to income capitalization. See Cook County Board of Review v.
    Property Tax Appeal Board, 
    384 Ill. App. 3d 472
    , 478, 487 (2008) (First District reversing the
    judgment of the PTAB with a limited remand for the reinstatement of the local board assessment,
    where the determinative issue on appeal resulted in a holding that the method of valuation adopted
    by the PTAB was legally erroneous). It is understandable that DSI seeks a remand to the PTAB.
    However, to arrive at a reliable fair cash value for Heritage Woods under the income capitalization
    approach, the PTAB would be required to reopen proofs and allow the parties to resubmit evidence,
    including additional expert opinions using proper valuation methodologies. This, in turn, would
    improperly afford DSI a second opportunity to correct the evidentiary deficiencies that caused its
    failure to sustain its burden of proof when challenging the correctness of the Local Board’s
    assessment. See id. at 484; 86 Ill. Adm. Code 1910.63(a), (b), (e) (2000).
    ¶ 89          For these reasons, we reverse the PTAB’s decision, which was based on an improper
    method for applying section 10-390’s income capitalization approach, to reduce the 2013 property
    tax assessment of Heritage Woods. We also conclude DSI, by relying on Honegger’s restricted use
    appraisal, failed to sustain its burden of proof. Since this issue is outcome determinative, we do
    not reach the alternative issue of whether the PTAB’s decision was arbitrary and capricious.

    ¶ 90                                        III. CONCLUSION
    ¶ 91          For the foregoing reasons, we reverse the judgment of the PTAB and direct that the Local
    Board’s assessment be reinstated.
