    Robert Wise, a resident of the Sundance Mobile Home Park (the Park), appeals
    from an adverse judgment on his complaint and petition for writ of mandate that
    challenged a decision of the City of Escondido's Mobilehome Park Rental Review Board
    (the Board) approving an application by the Park's owner, Amicorp Enterprises, Inc.
    (Amicorp),1 to raise the monthly rent of 29 spaces in the Park under the mobilehome rent
    control ordinance of the City of Escondido (the City). Wise contends (1) the trial court
    applied an improper legal standard in reviewing the Board's decision when it applied the
    substantial evidence test rather than the independent judgment test; and (2) under either
    legal standard, the Board's decision to approve a rent increase of $124.37 per month was
    not supported by the evidence. We conclude that Wise's arguments lack merit, and
    accordingly we affirm the judgment.
    I.
    FACTUAL AND PROCEDURAL BACKGROUND
    The Park was built in 1977 and is located in the City. It consists of 88
    mobilehome spaces and various amenities, including a large clubhouse and a swimming
    pool.
    From January 2006 to December 2010, all of the spaces at the Park were subject to
    five-year, long-term leases, which allowed for an annual rent increase of 75 percent of the
    1    Amicorp was erroneously identified in the caption of the complaint and writ of
    mandate as Americorp Enterprises, Inc.
    2
    consumer price index (CPI).2 Under Civil Code section 798.17, mobilehome spaces that
    are subject to leases for a term in excess of 12 months and that meet other conditions are
    exempt from regulation under local rent control ordinances.
    The long-term leases expired at the end of 2010. Several tenants decided not to
    renew their leases under the terms offered by Amicorp, and therefore those tenants'
    spaces became subject to the City's mobilehome rent control ordinance.
    On January 3, 2013, Amicorp submitted to the Board3 a long-form application for
    a rent increase on the spaces in the Park that were not covered by long-term leases.4 At
    the time the Board considered the application, 29 spaces were at issue, and the average
    then-existing monthly rent for those spaces was $534. In comparison, the average
    monthly rent for the 59 spaces still subject to long-term leases was $672. Amicorp's
    application sought permission to raise the rent on the 29 nonexempt spaces by $771.94,
    which would have resulted in an average monthly rent of $1,305.94 for those spaces.
    2       "The CPI 'is a statistical measure of fluctuations in urban consumers' costs of
    living widely used to measure the dollar's purchasing power. The United States Bureau
    of Labor Statistics computes the index by calculating percentage price changes of a
    sample "market basket" of goods and services in major expenditure groups, then weighs
    the percentage price changes in accordance with the relative importance of each item.
    The index is the average of these weighted percentage price changes.' " (H.N. & Frances
    C. Berger Foundation v. City of Escondido (2005) 
    127 Cal. App. 4th 1
    , 5, fn. 2 (Berger).)
    3      The Board is comprised of the members of the City Council.
    4      According to the record, the Board also allows for a " 'short-form' application,"
    under which a park owner may obtain a rent increase equal to 75 percent of the increase
    in the CPI without providing operating expense information. Under a short-form
    application, Amicorp would have been entitled to obtain an average monthly rent
    increase of $20.32 for the 29 spaces if the increase was not opposed by a majority of the
    impacted tenants.
    3
    Amicorp argued that an increase of $771.94 was required because it should be afforded a
    12 percent fair return on the value of the Park, which it determined to be $7,500,000. In
    the alternative, Amicorp took the position that the monthly rent for each space should be
    at least $950, based on what it contended were existing rental rates at comparable
    mobilehome parks.
    The Board retained expert Kenneth Baar to analyze Amicorp's application.5 Baar
    has served as a consultant to numerous California jurisdictions on rent control issues. In
    his report, Baar rejected the methodology suggested by Amicorp and instead employed
    the maintenance of net operating income (MNOI) approach to analyze whether a rent
    increase was required to allow Amicorp to obtain a fair return on its property. According
    to Baar, the Board historically used the MNOI standard when analyzing applications for
    rent increases, and courts have approved the use of the MNOI standard. As Baar
    explained, under an MNOI analysis, "fair return is defined as net operating income . . . as
    of a specified date adjusted by a specified inflation index." Specifically, "the fair net
    operating income for the current year is determined by 'indexing' the base year net
    operating income, based on a CPI factor."
    Baar used 1988 as the base year for the MNOI analysis, as that was the year when
    the City's mobilehome rent control ordinance was adopted. Baar's MNOI analysis then
    proceeded by (1) determining the net operating income that Amicorp received for the
    5      The Board also retained James Brabant to analyze Amicorp's position concerning
    the rents lawfully charged in comparable mobilehome parks. We do not further discuss
    Brabant's analysis, as it is not pertinent to the issues on appeal.
    4
    spaces at the Park as of 1988; (2) adjusting that amount by a percentage of the increase in
    the CPI between 1988 and 2012 to determine the present-day equivalent of the 1988 net
    operating income; and (3) determining whether any increase in rent was needed to enable
    Amicorp to obtain the same effective net operating income that it was receiving in 1988.
    As a result of his MNOI analysis, Baar concluded that to afford Amicorp a fair return on
    the Park, depending upon certain assumptions made as to three variables, a minimum rent
    adjustment ranging from zero to $179.35 was required. This range of possible outcomes
    was set forth on "Table 6" in Baar's report that set forth 16 different possible rent
    adjustments.
    Baar's report explained that the range of figures for the minimum required rent
    adjustment in Table 6 resulted from different possible assumptions by the Board as to
    three variables:
    "(a) Should the income from all spaces or only the rent controlled spaces
    be considered in the analysis.
    "(b) In determining fair net operating income should the base period net
    operating income be adjusted by 40% or 100% or some other percentage of
    the percentage increase in the CPI since the base year.
    "(c) Should any adjustments be made to [Amicorp's] projections of base
    year and current year income and operating expenses for the purposes of a
    [MNOI] analysis."
    Although Baar's report set forth arguments for and against selecting certain
    outcomes as to the three variables, he did not endorse any specific approach. At the
    Board hearing on Amicorp's application, Baar made clear that, in his expert opinion, it
    would be acceptable to resolve the three variables in any manner the Board considered
    5
    appropriate. Therefore, in Baar's opinion the Board reasonably could select any monthly
    rent increase for the 29 spaces within the range of figures included in Table 6, ranging
    from zero to $179.35.6
    On August 28, 2013, the Board held a hearing on Amicorp's application. Several
    residents of the Park spoke in opposition to the application and submitted written
    materials prior to the hearing. At the conclusion of the hearing, the Board approved a
    monthly rent increase of $124.37 per space for the 29 spaces at issue.7
    The Board members' comments made clear that the Board had proceeded by
    selecting $124.37 from Table 6 of Baar's report and thereby resolving the three variables
    that Baar identified by (1) using the income from the rent controlled spaces, not from the
    entire Park; (2) indexing the base year income by a factor of 75 percent of the increase in
    the CPI; and (3) not making any adjustments to the net operating income and expense
    6       Specifically, at the hearing a Board member asked Baar about the range of figures
    set forth on Table 6, inquiring whether "from your perspective . . . this Board actually has
    an opportunity to . . . , in theory, to choose any of these numbers, based upon the
    direction they want to go, correct?" Baar answered, "Right. Yes." Baar added the
    qualification that on the issue of whether to use income from only the rent-controlled
    spaces or from the whole Park, "there's been very little test of this issue legally" and thus
    "looking at the rent-controlled spaces" would be "taking a more . . . conservative or
    careful approach."
    7       The Board also granted Amicorp's request to charge the Park residents for $25,000
    in fees incurred in connection with the application, with payments prorated among the
    residents and spread over five years. We note that the Board's resolution originally
    directed that the costs were to be divided among the 88 spaces in the Park, but upon
    application by Amicorp, the Board amended the resolution to provide that the cost award
    was to be divided among the 29 spaces that were the subject of the rent increase
    application, for a temporary rent increase of $17.07 per month. Wise makes no specific
    legal argument challenging the award of the $25,000 in fees to Amicorp, and we
    accordingly do not consider that issue.
    6
    figures submitted by Amicorp for the base year and the current year. During the hearing,
    Board members commented that a rent increase of $124.37 per month (for an average
    total rent of $658.37 per month) would be a fair, just and reasonable rent based on the
    superior quality of the Park, the fact that the 59 other residents of the Park had voluntarily
    entered into leases at an average amount of $672 per month, and the fact that the rent
    payment included the provision of utilities.
    The Board's decision was formally adopted in a resolution on September 11, 2013.
    The resolution declared that "an increase of $124.37 according to a [MNOI] analysis with
    a 75 percent CPI indexing ratio and using only rent controlled income provides a fair
    return, and provides a rent approaching the rents paid by residents who have long[-]term
    leases at [the Park]." It further declared that "a 75 percent indexing ratio for the [MNOI]
    is fair, just, and reasonable because it is in line with the indexing ratios used by other
    municipalities in California." Accordingly, the resolution set forth the Board's
    determination that "an average increase of $124.37 per space per month is fair, just, and
    reasonable"
    Wise and three other residents of the Park filed a complaint for declaratory relief
    and a petition for writ of mandate against the City and the Board on January 14, 2014,
    (collectively, the Petition) with Amicorp named as the real party in interest. The Petition
    alleged the Board abused its discretion by approving the rent increase of $124.37 per
    month in that it made certain unwarranted decisions as to the three variables set forth in
    Baar's MNOI analysis. The relief sought included an order declaring the Board's decision
    to be void and the issuance of a writ of mandate directing the Board to vacate its decision.
    7
    The parties stipulated that the trial court would consider the Petition by way of a
    noticed motion for issuance of a writ of mandate, with a stipulated briefing schedule.
    The briefing in favor of the writ of mandate argued (1) the trial court should apply the
    independent judgment test in reviewing the Board's decision, rather than the substantial
    evidence standard; and (2) under any standard, the Board abused its discretion in how it
    resolved the question of the three variables pertinent to the MNOI analysis identified in
    Baar's report.
    After considering the matter, the trial court entered judgment against Wise and the
    other petitioners, concluding that the Board's decision was supported by substantial
    evidence in the record.
    II.
    DISCUSSION
    A.     As No Fundamental Vested Rights Are at Issue, the Board's Decision Is Reviewed
    to Determine If It Is Supported by Substantial Evidence
    We first consider Wise's contention that because fundamental vested rights of the
    Park's residents are purportedly implicated by the Board's rent control decision, the trial
    court should have reviewed the Board's decision under an independent judgment
    standard, not the substantial evidence standard.
    "An aggrieved party may seek judicial review by a trial court of a local
    mobilehome rent control board's final decision by seeking a writ of mandate . . ." under
    Code of Civil Procedure section 1094.5. (Carson Harbor Village, Ltd. v. City of Carson
    Mobilehome Park Rental Review Bd. (1999) 
    70 Cal. App. 4th 281
    , 287 (Carson Harbor
    8
    Village).) In such a proceeding, " '[a] trial court's review of an adjudicatory
    administrative decision is subject to two possible standards of review depending upon the
    nature of the right involved. . . . If the administrative decision substantially affects a
    fundamental vested right, the trial court must exercise its independent judgment on the
    evidence. . . . The trial court must not only examine the administrative record for errors
    of law, but must also conduct an independent review of the entire record to determine
    whether the weight of the evidence supports the administrative findings. . . . If, on the
    other hand, the administrative decision neither involves nor substantially affects a
    fundamental vested right, the trial court's review is limited to determining whether the
    administrative findings are supported by substantial evidence.' " (Saraswati v. County of
    San Diego (2011) 
    202 Cal. App. 4th 917
    , 926, citations omitted (Saraswati).) When a
    substantial evidence standard applies to the trial court's consideration of a petition for
    writ of mandate, as an appellate court "we 'answer the same key question as the trial court
    . . . whether the agency's findings were based on substantial evidence.' " (MHC
    Operating Limited Partnership v. City of San Jose (2003) 
    106 Cal. App. 4th 204
    , 218-219
    (MHC).)
    "[C]ourts must decide on a case-by-case basis whether an administrative decision
    substantially affects fundamental vested rights, and there is no fixed formula which
    guarantees a predictably exact ruling in each case. The essence of the determination is to
    protect the fundamental rights of the individual from abrogation without judicial, as
    opposed to administrative, review. . . . In analyzing the fundamental nature of the right,
    the court manifests slighter sensitivity to the preservation of purely economic privileges."
    9
    (San Marcos Mobilehome Park Owners' Assn. v. City of San Marcos (1987) 
    192 Cal. App. 3d 1492
    , 1499, citation & fn. omitted (San Marcos).) "An inquiry must be made
    on a case-by-case basis as to whether the property right at issue fundamentally affects the
    life situation of the individual, or whether it merely impacts an area of economic
    privilege in a less than fundamental manner." (Id. at p. 1502.) The right must not only
    be fundamental, but also vested. Thus, the court asks whether the right "is possessed by,
    and vested in, the individual or merely sought by him. In the latter case, since the
    administrative agency must engage in the delicate task of determining whether the
    individual qualifies for the sought right, the courts have deferred to the administrative
    expertise of the agency." (Bixby v. Pierno (1971) 
    4 Cal. 3d 130
    , 144, italics added
    (Bixby).) "Fundamental vested rights are often found in the context of public
    employment rights, licensing decisions, public assistance benefits and land use."
    
    (Saraswati, supra
    , 202 Cal.App.4th at p. 927.)
    Case law has repeatedly held that when the owner of a mobilehome park brings a
    petition for writ of mandate to challenge the decision of a mobilehome rent control board,
    the trial court applies a substantial evidence standard of review. 
    (Berger, supra
    , 127
    Cal.App.4th at p. 7; 
    MHC, supra
    , 106 Cal.App.4th at p. 218; Rainbow Disposal Co. v.
    Escondido Mobilehome Rental Review Bd. (1998) 
    64 Cal. App. 4th 1159
    , 1165 (Rainbow);
    Westwinds Mobile Home Park v. Mobilehome Park Rental Review Bd. (1994) 
    30 Cal. App. 4th 84
    , 90; Yee v. Mobilehome Park Rental Review Bd. (1993) 
    17 Cal. App. 4th 1097
    , 1106 (Yee); San 
    Marcos, supra
    , 192 Cal.App.3d at p. 1500.) Specifically, case law
    holds that although a mobilehome park owner's rights to substantive due process and to
    10
    be protected from an unconstitutional taking of its property are implicated in a rent
    control proceeding (Galland v. City of Clovis (2001) 
    24 Cal. 4th 1003
    , 1024 (Galland);
    Kavanau v. Santa Monica Rent Control Bd. (1997) 
    16 Cal. 4th 761
    , 770 (Kavanau)), the
    owner's fundamental vested rights are not at issue in such a proceeding, as rent increases
    fall into the less sensitive category of the " 'preservation of purely economic privileges.' "
    (San Marcos, at p. 1500; see also MHC, at pp. 217-218; see also Concord Communities v.
    City of Concord (2001) 
    91 Cal. App. 4th 1407
    , 1414.)
    Wise argues that this case law is not controlling because this is an action brought
    by the residents of a mobilehome park, not the park owner. Challenges brought by
    residents of mobilehome parks to decisions of mobilehome rent control boards are
    uncommon in the published case law. Accordingly, we are aware of only one published
    authority that has considered the issue of the standard of review applicable when
    residents of a mobilehome park challenge the decision of a rent control board. In that
    decision, Robinson v. City of Yucaipa (1994) 
    28 Cal. App. 4th 1506
    , residents of a
    mobilehome park contended that a provision of the Civil Code preempted a city
    ordinance allowing a mobilehome park owner to obtain a rent increase based on capital
    improvement expenses. (Id. at p. 1512.) Robinson concluded that the preemption issue
    was a matter of statutory interpretation subject to independent review. (Id. at pp. 1516-
    1517.) However, Robinson went on to observe that "[t]he remaining question, the
    propriety of the Commission's approval of a rent increase, is a question of fact subject to
    review under the substantial evidence standard. Residents do not challenge the
    sufficiency of the evidence to support the Commission's decision." (Id. at p. 1517, italics
    11
    added.) As we will explain, although Robinson's statement about the substantial evidence
    standard of review in Robinson is arguably dictum, we perceive no reason to depart from
    Robinson's holding.
    First, whatever rights Wise might identify as being at stake in a rent control
    proceeding, any such rights would be purely economic. "[W]hen a case involves or
    affects purely economic interests, courts are far less likely to find a right to be of the
    fundamental vested character." (JKH Enterprises, Inc. v. Department of Industrial
    Relations (2006) 
    142 Cal. App. 4th 1046
    , 1060.) Courts acknowledge that in some
    exceptional circumstances an economic right might qualify as fundamental if the loss of
    that right could "fundamentally affect[] the life situation of the individual." (San 
    Marcos, supra
    , 192 Cal.App.3d at p. 1502.) However, that is not the situation here. Although
    Wise makes a vague suggestion that park residents could end up being evicted if a rent
    increase was too high, there is no evidence in the record that any eviction will occur as a
    result of the $124.37 rent increase approved by the Board. (See San 
    Marcos, supra
    , 192
    Cal.App.3d at p. 1502 [stating that fundamental vested rights were not at issue because
    "there is no contention, nor does the evidence suggest, that if the [agency] denied the
    requested rent increases, the park owners would be in such an unfavorable economic
    position they would go out of business"].)
    Further, Wise cannot establish that any rights have vested in the Park residents.
    The Park's residents do not already possess a right to pay only a specific amount of rent.
    (See 
    Bixby, supra
    , 4 Cal.3d at p. 144 [a right is not vested if it is "merely sought"].) This
    situation is therefore not comparable to the cases cited by Wise in which a party already
    12
    had a vested right to a service-connected death allowance under a retirement plan
    (Strumsky v. San Diego County Employees Retirement Assn. (1974) 
    11 Cal. 3d 28
    ) or a
    conditional use permit for a preexisting business (Goat Hill Tavern v. City of Costa Mesa
    (1992) 
    6 Cal. App. 4th 1519
    ).
    We accordingly conclude that use of the substantial evidence standard of review is
    appropriate in this case. " 'In general, substantial evidence has been defined . . . as
    evidence of " ' "ponderable legal significance . . . reasonable in nature, credible, and of
    solid value" ' " [citation]; and . . . as " 'relevant evidence that a reasonable mind might
    accept as adequate to support a conclusion.' " ' " 
    (Berger, supra
    , 127 Cal.App.4th at
    p. 7.)
    B.       The Board's Decision Is Supported by Substantial Evidence
    Application of the substantial evidence test "inherently requires that the reviewing
    court first determine the question, 'Substantial evidence of what?' " 
    (Yee, supra
    , 17
    Cal.App.4th p. 1106.) To answer that question, we look to the City's mobilehome rent
    control ordinance, the applicable constitutional standards and applicable case authority.
    1.     Legal Standards Applicable to the Board's Decision
    Here, the City's mobilehome rent control ordinance provides:
    "The board shall approve such rent increase as it determines to be just, fair
    and reasonable. The board shall consider the following factors, in addition
    to any other factors it considers relevant, in making such determination:
    "(1) Changes in the Consumer Price Index for All Urban Consumers in San
    Diego Metropolitan Area published by the Bureau of Labor Statistics.
    "(2) The rent lawfully charged for comparable mobilehome spaces in the
    City of Escondido.
    13
    "(3) The length of time since either the last hearing and final determination
    by the board on a rent increase application or the last rent increase if no
    previous rent increase application has been made.
    "(4) The completion of any capital improvements or rehabilitation work
    related to the mobilehome space or spaces specified in the rent increase
    application, and the cost thereof, including such items of cost, including
    materials, labor, construction interest, permit fees, and other items as the
    board deems appropriate.
    "(5) Changes in property taxes or other taxes related to the subject
    mobilehome park.
    "(6) Changes in the rent paid by the applicant for the lease of the land on
    which the subject mobilehome park is located.
    "(7) Changes in the utility charges for the subject mobilehome park paid by
    the applicant and the extent, if any, of reimbursement from the tenants.
    "(8) Changes in reasonable operating and maintenance expenses.
    "(9) The need for repairs caused by circumstances other than ordinary wear
    and tear.
    "(10) The amount and quality of services provided by the applicant to the
    affected tenant.
    "(11) Any existing written lease lawfully entered into between the applicant
    and the affected tenant." (Escondido Mun. Code, § 29-104, subd. (g),
    italics added.)
    Case law explains that a review board should set a rent that falls within a "broad
    zone of reasonableness." 
    (Galland, supra
    , 24 Cal.4th at p. 1026.) "[W]ithin this broad
    zone, the rate regulator is balancing the interests of investors, i.e., landlords, with the
    interests of consumers, i.e., mobilehome owners, in order to achieve a rent level that will
    on the one hand maintain the affordability of the mobilehome park and on the other hand
    allow the landlord to continue to operate successfully." (Ibid.) A rent increase should be
    14
    " 'one which is not so high as to defeat the purpose of rent control nor permit landlords to
    demand of tenants more than the fair value of the property and services which are
    provided.' " (Oceanside Mobilehome Park Owners' Assn. v. City of Oceanside (1984)
    
    157 Cal. App. 3d 887
    , 907.)
    In challenges brought by park owners, an additional requirement is added to a
    rental control review board's inquiry, as park owners have a constitutional right to a fair
    return on their property. " 'Constitutionally valid rent control schemes must allow park
    owners to earn a "just and reasonable" or "fair" return on their investment.' " 
    (Berger, supra
    , 127 Cal.App.4th at p. 7.) Thus, case law implies into all mobilehome rent control
    ordinances, including the City's, the additional requirement that when determining a
    reasonable rent, the review board must also find that the park owner is, at a minimum,
    receiving a fair return on its property. (Carson Harbor 
    Village, supra
    , 70 Cal.App.4th at
    p. 288 ["Fair return is the constitutional measuring stick by which every rent control
    board decision is evaluated."].)
    "Although the term 'fair rate of return' borrows from the terminology of economics
    and finance, it is as used in this context a legal, constitutional term. It refers to a
    constitutional minimum within a broad zone of reasonableness." 
    (Galland, supra
    , 24
    Cal.4th at p. 1026.) No specific method is required to be used to arrive at a fair return.
    "The California Supreme Court has 'expressly reject[ed] the notion that any particular
    formula must be used in determining a just and reasonable return.' . . . Rather, the
    'selection of an administrative standard by which to set rent ceilings is a task for local
    governments . . . and not the courts.' " 
    (Berger, supra
    , 127 Cal.App.4th at pp. 8-9,
    15
    citations omitted.) Thus, we focus on whether "the regulatory scheme's result is just and
    reasonable" not the method by which it was reached. 
    (Kavanau, supra
    , 16 Cal.4th at
    p. 778; see also Carson Mobilehome Park Owners' Assn. v. City of Carson (1983) 
    35 Cal. 3d 184
    , 191.) Courts have specifically approved the use of the MNOI analysis as an
    acceptable method of determining whether a rent increase is required to afford a park
    owner a minimum fair return on its property. 
    (Berger, supra
    , 127 Cal.App.4th at p. 9;

    both its fairness and ease of administration.' "].)
    2.     Wise's Challenge to the Board's Decision
    We now turn specifically to Wise's challenges to the Board's decision. Wise
    contends that based on the evidence before the Board, the Board was not justified in its
    decision to resolve the issue of the three variables set forth in Baar's MNOI analysis by
    (1) using the income from the rent controlled spaces, not from the entire Park;
    (2) indexing the base year income by a factor of 75 percent of the increase in the CPI; and
    (3) not making any adjustments to the net operating income and expense figures
    submitted by Amicorp for the base year and the current year. Wise contends that the
    Board should have opted for a different resolution as to the three variables, and had it
    done so, the Board would have chosen one of the lower rental adjustments from the 16
    16
    options set forth on Table 6 in Baar's report.8 As we will explain, Wise's argument is
    without merit because substantial evidence supports the Board's decision to resolve the
    three variables as it did.
    At the outset we note that it is a matter of expert opinion whether a park owner is
    obtaining a fair return. "Weighing the competing interests of owners and tenants and
    satisfying constitutional criteria is not a task within common experience. To the contrary,
    courts 'consider it a matter of expert opinion what rate of return on a mobilehome park is
    fair.' " 
    (Berger, supra
    , 127 Cal.App.4th at p. 11.) Here, as we have described, Baar
    stated that any resolution of the three variables and any of the 16 options set forth on
    Table 6 would be reasonable based on his expert opinion. Therefore, relying on Baar's
    expert opinion, as we must, the Board's decision to select the amount of $124.37 as the
    8       Although Wise's appellate arguments focus on challenging the Board's MNOI
    analysis, we note that some of the factors in the City's mobilehome rent control ordinance
    are not directed at an MNOI analysis, but instead focus more on determining whether
    park residents are paying more than a just, fair and reasonable rent. These factors include
    "[t]he rent lawfully charged for comparable mobilehome spaces in the City of Escondido"
    and "[t]he amount and quality of services provided by the applicant to the affected
    tenant." (Escondido Mun. Code, § 29-104, subd. (g)(2) & (10).) The Board focused on
    both of those factors during the hearing when it commented on the superior quality of the
    Park (which included the provision of utilities) and the comparable rents voluntarily
    agreed to by the tenants in the Park who entered into long-term leases. Although not his
    main point, Wise comments that any rental rate not arrived at through the rental control
    review process is necessarily unreasonably high and unfair to renters, so that it was
    unreasonable for the Board to have relied on the fact that the Park's other residents paid
    an average of $672 under their long-term leases. Wise's assumption is flawed. The City's
    mobilehome rent control ordinance necessarily impacts the prices that mobilehome park
    residents will voluntarily agree to pay in long-term leases. Mobilehome park residents in
    the City have the option, as Wise and 28 other Park residents chose here, to refuse to
    enter into a lease they believe is unreasonable, and to force the park owner to rely on the
    rent control review process to set the rent.
    17
    minimum rent increase required under the MNOI analysis is supported by substantial
    evidence.
    Wise erroneously contends that the Board "refused to adopt either the reasonable
    assumptions or the accurate formulas presented by Dr. Baar." According to Wise, Baar
    made a "recommendation that either [Amicorp] receive no rent increase, or that [it]
    receive the same $20.32 rent increase [it] would have obtained by using the 'short form' "
    application. Wise misrepresents the record, as Baar made no such recommendation. On
    the contrary, as we have explained, Baar's MNOI analysis set forth a range of possible
    minimum required rent increases, between zero and $179.35, depending on how the
    Board decided to resolve the three variables that he presented, and Baar made clear that
    any figure the Board selected from the range presented would be reasonable in his expert
    opinion. Thus, this case is not similar to Berger, which determined that the Board's rent
    increase was not supported by substantial evidence when the Board rejected Baar's expert
    opinion about the minimum rent increase required under an MNOI analysis and instead
    used its own method to arrive at a lower rent increase that Baar concluded was
    constitutionally required. 
    (Berger, supra
    , 127 Cal.App.4th at p. 12 ["Dr. Baar neither
    recommended a $25 rent increase based on the single factor of comparable rents, nor
    stated such an increase would satisfy the fair return standard. Rather, he believed a
    minimum increase of $38.44, under a modified MNOI standard, was required to meet the
    fair return standard."].) Here, the Board specifically followed Baar's recommendation to
    choose a figure within the ranges presented in Table 6 of Baar's report to afford Amicorp
    a minimum fair return.
    18
    Case law makes clear that it is not our role as a court to delve into the method of
    how an administrative body determines whether a park owner is receiving a fair return.
    
    (Berger, supra
    , 127 Cal.App.4th at pp. 8-9.) Nevertheless, when we focus on the details
    of Baar's expert report and the other evidence at the hearing we find that the record amply
    supports the Board's decision on each of the three variables that led it to select $124.37 as
    the minimum rental increase required to afford Amicorp a fair return.9
    a.     Considering Income from Only Rent-controlled Spaces
    The first of the three variables that Baar identified was whether "the income for all
    spaces or only the rent controlled spaces be considered in the analysis." As we have
    explained, the Board chose to use the income from only the rent-controlled spaces in its
    analysis.
    Substantial evidence supports the Board's decision to rely on only the rent-
    controlled spaces. Specifically, Baar explained in his report that "[t]here are notable
    rationale for including and for excluding the income from the exempt spaces in an MNOI
    analysis."10 In support of considering the income from only rent-controlled spaces, Baar
    9       In his opening brief, Wise also argues that Baar's MNOI analysis adopted by the
    Board was flawed because it assumed a base year of 1988 rather than 2010. Wise did not
    raise this argument in the trial court, and we will not consider it for the first time on
    appeal. (Perez v. Grajales (2008) 
    169 Cal. App. 4th 580
    , 591-592 [" '[I]t is fundamental
    that a reviewing court will ordinarily not consider claims made for the first time on
    appeal which could have been but were not presented to the trial court.' [Citation
    omitted.] Such arguments raised for the first time on appeal are generally deemed
    forfeited."].)
    10    As Baar correctly acknowledged, no case law specifically requires use of either
    approach. Wise's citations to Morgan v. City of Chino (2004) 
    115 Cal. App. 4th 1192
    ;
    19
    explained that "[i]f all of the income from a mobilehome park is considered when a
    substantial portion of the spaces are exempt from rent regulation[,] a park owner may
    never be entitled to increase the net operating income yielded by rent controlled spaces,"
    and "[t]his outcome may be seen as going beyond the purpose of providing protection
    against unreasonable rent increases." Moreover, as Baar stated at the hearing, the more
    conservative approach would be to use only the income from the rent controlled spaces.
    These expert statements by Baar provide substantial evidence in the record for the
    Board's choice to select a minimum required rent increase that was based on an MNOI
    analysis using income from only the rent-controlled spaces.
    b.     Indexing Factor of 75 Percent of the Increase in the CPI
    The second variable identified by Baar was whether "[i]n determining fair net
    operating income . . . the base period net operating income [should] be adjusted by 40%
    or 100% or some other percentage of the percentage increase in the CPI since the base
    year." As we have explained, the Board chose to use an indexing factor of 75 percent of
    the increase in the CPI. In the trial court, Wise took the position that the Board was
    required to apply an indexing factor of no more than 40 percent of the increase in CPI.
    Now, on appeal, Wise appears to contend that an indexing factor of no more than
    Carson Harbor 
    Village, supra
    , 
    70 Cal. App. 4th 281
    ; and Penn Central Transp. Co. v.
    New York City (1978) 
    438 U.S. 104
    do not support his argument because none of them
    held that only rent controlled spaces may be considered in an MNOI analysis.
    20
    60 percent was required.11 Neither position is meritorious because, as we will explain,
    substantial evidence supports the Board's selection of a 75 percent indexing factor.
    Baar's report explained that the City had traditionally used a 40 percent indexing
    rate. In addition, under the short form procedure, park owners are entitled to a 75 percent
    of CPI increase. Baar pointed out that no specific indexing rate was legally required, and
    "[a]mong the rent controlled jurisdictions which use MNOI standards there are significant
    differences in the rates by which net operating income is adjusted. 'Indexing ratios' vary
    from 40% to 100% of the percentage increase in the CPI." Baar provided a chart that
    showed the range in different jurisdictions. As one of the Board members observed at the
    hearing, based on the chart prepared by Baar, an indexing rate of 75 percent appeared to
    be the average rate applied in other jurisdictions.
    Baar also explained the theoretical justification for applying less than a
    100 percent CPI indexing rate in an MNOI analysis for a mobilehome park. Put simply, a
    mobilehome park is usually a leveraged investment in which a park owner's equity in the
    real estate investment will normally increase at a rate greater than the increase in the CPI,
    11     Wise's current position that the Board was required to apply no more than a
    60 percent indexing rate appears to be based on his assertion that guidelines adopted by
    the Board call for the application of a 60 percent indexing rate. We note that the
    guidelines that Wise refers to are not included in the record, but written comments that
    the City staff prepared for the hearing on Amicorp's application do quote from them to
    some extent. Because neither the full text of the guidelines, nor an explanation of their
    intended role in the Board's decisionmaking are before us, we do not consider Wise's
    argument to the extent it is based on the Board guidelines. Further, Wise has presented
    no reason why the Board could not depart from their guidelines based on Baar's expert
    opinion.
    21
    so that a fair return is afforded to the park owner even when rents for the spaces in the
    park do not increase by a factor of 100 percent of the CPI increase.12
    Based on this material in the record, we conclude that substantial evidence
    supports the Board decision to select a 75 percent indexing factor as part of the MNOI
    analysis, and thereby arrive at a minimum required rent increase of $124.37.
    c.     No Adjustment to Base Year and Current Year Income and
    Operating Expenses
    The final variable identified by Baar was "[s]hould any adjustments be made to
    [Amicorp's] projections of base year and current year income and operating expenses for
    the purposes of a[n MNOI] analysis." Specifically, Baar presented three possible
    adjustments to the income and operating expense figures supplied by Amicorp, and he
    gave the Board the option whether to make those adjustments in its MNOI analysis. As
    noted, the Board chose not to make any adjustment to the figures presented by Amicorp.
    We consider whether substantial evidence supports the Board's decision not to make the
    adjustment to Amicorp's figures.
    i.     Discrepancy with Previously Submitted Figures
    Baar pointed out that Amicorp had made a prior application for a rental increase in
    1989, and at the time of that application, it claimed to have income and operating
    expenses for 1988 that were different from the 1988 income and operating expenses
    12     Baar stated, "The 'leveraged' nature of real estate investments may allow investors
    to obtain a reasonable return on their investments when rates of indexing are well below
    100% of CPI. As a result of the leveraging factor, the return on investment may be a
    multiple of the rate of increase in the net operating income and value of the property."
    22
    identified in the 2013 application, with the new application including $3,233 less in
    operating expenses. Baar discussed the possibility of using the old figures rather than the
    new figures, but he also pointed out that the old figures were not complete because some
    of the document that Amicorp submitted in 1989 was cut off in photocopying. Further,
    Amicorp pointed out that the figures in the 1989 application were not necessarily
    prepared or reviewed by a certified public accountant (CPA). Amicorp's CPA stated that
    the figures used in Amicorp's 2013 submission were more reliable, as they were based on
    profit and loss statements prepared by a CPA.
    We conclude that based on the statement from Amicorp's CPA that the new
    figures were more reliable, and the fact that the document from 1989 was incomplete,
    there was substantial evidence in the record supporting the Board's decision not to make
    an adjustment to the figures that Amicorp submitted in 2013 based on the discrepancy
    with the 1989 submission.
    ii.    Imputed 5 Percent Management Fee
    Baar pointed out that Amicorp included an imputed 5 percent management fee
    when setting forth its operating expense projection for 2012, which Baar found to be a
    reasonable approach. However, Baar also pointed out that Amicorp did not include a
    comparable 5 percent management fee in its operating expenses for the base year of
    1988. Baar therefore stated that Amicorp's income and expenses for 1988 could be
    adjusted by adding an imputed 5 percent management fee expense of $15,193 for that
    year. As with Baar's other possible adjustments, the Board did not make this adjustment
    in its MNOI analysis.
    23
    Amicorp's CPA, Gary Capata, spoke at the hearing and explained to the Board
    why Baar's suggested adjustments were not necessary. Capata explained, "We already
    made adjustments as appropriate. We feel that when Dr. Baar makes adjustments, he
    misstates the already adjusted results."
    As Capata had expertise as a CPA and was the person who prepared the relevant
    financial documents, the Board properly could decide to rely on Capata's testimony as
    substantial evidence for not making the adjustment of $15,193 to the 1988 income and
    expense figures.
    iii.   Maintenance Expenses
    Amicorp projected maintenance expenses of $45,424 for 2012. However, as Baar
    pointed out, Amicorp's maintenance expenses fluctuated widely over the previous five
    years. Therefore Baar suggested that the Board could average the types of maintenance
    expenses for the past five years rather than using Amicorp's projection, which would
    result in $35,662 in maintenance expenses for 2012.
    At the hearing, Capata disagreed with Baar's suggested adjustment. He stated that
    he did not agree that maintenance expenses should "be based on the past five years" and
    he "[did not] see a justification" for the adjustment. As Capata explained, "Costs are
    increasing every year. This is an old park."
    The Board was entitled to rely on Capata's opinion as a CPA and as someone
    familiar with the Park's financial condition. Accordingly, substantial evidence supports
    the Board's decision not to make the adjustment identified by Baar.
    24
    Having reviewed each contention raised by Wise challenging the Board's MNOI
    analysis, we conclude that Wise's arguments lack merit, and the Board's decision
    allowing Amicorp to institute a $124.37 monthly rental increase for the 29 spaces
    covered by Amicorp's application is supported by substantial evidence.
    DISPOSITION
    The judgment is affirmed. Respondents are awarded their costs on appeal.
