At issue in these consolidated cases is the correctness of administrative decisions issued by the Louisiana Tax Commission *162("Commission") on review of the valuations, for the 2014 and 2015 tax years, by the Orleans Parish Tax Assessor ("Assessor") of a low-income housing development, owned by Opportunity Homes Limited Partnership ("Opportunity Homes"), for purposes of assessment of ad valorem taxes. The Commission ruled in favor of Opportunity Homes for both tax years. The administrative decisions were upheld by the district court but reversed by the appellate court. For the reasons that follow, we reverse the appellate court and reinstate the assessment values as determined by the Commission.
FACTS AND PROCEDURAL HISTORY
The factual and procedural history of this case was concisely set forth by the appellate court as follows:
Opportunity Homes describes itself as a "scattered-site, low income affordable housing development." It consists of thirty-two (32) single- and double-unit residential buildings. The separate properties are connected by way of a Tax Credit Regulatory Agreement ("TCRA"). Opportunity Homes notes the TCRA prohibits separation and sale of the various properties, and restricts the chargeable rents to "no more than sixty percent (60%) of the Area Median Income ("AMI")" for an extended period of time, but the rates are even lower for some buildings.
Pursuant to the powers and authority delegated to him by La. R.S. 47:1903, La. R.S. 47:1957, and La. R.S. 47:2323, Assessor Williams determined the fair market value ("FMV") of Opportunity Homes' scattered-site properties using what is known as the "market approach." In using this particular approach, Assessor Williams determined the FMV of Opportunity Homes' properties to be $4,200,900 and $4,083,610 for tax years 2014 and 2015, respectively.[1 ]
Pursuant to its authority under La. Const. Art. VII, § 18, the Commission reviewed the "correctness" of Assessor Williams' assessment. At a January 13, 2015 hearing, counsel for Opportunity Homes noted that in 2013, the same properties were valued at $1,525,000, and assessed accordingly. The Commission relied on assessments by Randy Harrington, its own staff appraiser, who used what is known as the "income approach" and reached FMVs of $1,525,000 for both tax years 2014 and 2015, which assessments specifically excluded the value of "Low Income Housing Tax Credits" ("LIHTCs") received by the taxpayer for encumbering the properties with below-market-value rents. Counsel for Opportunity Homes noted that pursuant to adopted and promulgated regulations, the income approach is the "recommended" approach for determining the FMV of "affordable rental housing." Based on the foregoing, the Commission moved to accept the staff recommendations as to each tax year.
As a result of the Commission's actions, on September 2, 2015, Assessor Williams commenced suit in the district court pursuant to La. R.S. 47:1998, La. R.S. 47:1989 and La. R.S. 49:964. The *163district court affirmed the Commission's decision, finding that the Commission's decision "was not in violation of any constitutional or statutory provisions, was not in excess of its statutory authority, was not made upon unlawful procedure, or affected by other error of law, was not arbitrary or capricious or characterized by abuse of discretion or clearly unwarranted exercise of discretion." The district court further noted the decision "was clearly supported by the testimony and preponderance of the evidence before it, where [the Commission] had the opportunity to judge the credibility of witnesses by first-hand observation."
Williams v. Opportunity Homes Limited Partnership , 16-1185, pp. 1-3 (La. App. 4 Cir. 5/10/17), 220 So.3d 188, 189-90. Upon review, the appellate court ruled that the Commission's decisions were "in violation of statutory provisions, in excess of its authority, ... based upon unlawful procedures," and "legally incorrect." Id. , 16-1185 atp. 4, 220 So.3d at 191. Accordingly, the appellate court reversed and reinstated the Assessor's fair market values for the 2014 and 2015 tax years. Id.
Both Opportunity Homes and the Commission sought review in this court, and we granted the writ applications. Williams v. Opportunity Homes Limited Partnership , 17-0955, 17-0957 (La. 10/27/17), 228 So.3d 1228.
Opportunity Homes urges this court to reverse, contending the appellate court decision: is in conflict with other jurisprudence, harms the administrative authority of the Commission; negatively impacts statewide uniformity for ad valorem property assessment and taxation; misinterprets jurisprudence and law (including the Louisiana Administrative Procedure Act ("APA"), La. R.S. 49:950 et seq., relative to review of administrative agency decisions); and, alternatively, should have remanded the matter to the Commission to determine whether the market/sales comparison approach could have been applied to value the subject property so as to ensure statewide uniformity. The Commission additionally asserts that the appellate court erred in reversing the decisions of the Commission and the district court since there was "no evidence to reinstate prior assessed values of the Orleans Parish Assessor."
LAW AND ANALYSIS
The essence of the dispute between the Assessor and Opportunity Homes is whether the method of valuing Opportunity Homes' low-income housing development for purposes of ad valorem taxation should be via the "market approach," as asserted by the Assessor, or via the "income approach," as asserted by Opportunity Homes.
As stated in La. Const. Art. VII, § 18 (A), "[p]roperty subject to ad valorem taxation shall be listed on the assessment rolls at its assessed valuation, which ... shall be a percentage of its fair market value. The percentage of fair market value shall be uniform throughout the state upon the same class of property."2 Each assessor *164is authorized by La. Const. Art. VII, § 18 (D), to "determine the fair market value of all property subject to taxation within his respective parish or district except public service properties, which shall be valued at fair market value by the Louisiana Tax Commission or its successor."
The fair market value shall be determined in accordance with criteria established by law, which must be uniformly applied throughout the state. La. Const. Art. VII, § 18 (D); La. R.S. 47:2323(A). Fair market value is defined by La. R.S. 47:2321 as "the price for property which would be agreed upon between a willing and informed buyer and a willing and informed seller under usual and ordinary circumstances; it shall be the highest price estimated in terms of money which property will bring if exposed for sale on the open market with reasonable time allowed to find a purchaser who is buying with knowledge of all the uses and purposes to which the property is best adapted and for which it can be legally used."
In furtherance of maintaining the uniformity required by La. Const. Art. VII, § 18 (D), La. R.S. 47:2323(A) provides that "[u]niform guidelines, procedures and rules and regulations as are necessary to implement said criteria shall be adopted by the Louisiana Tax Commission only after public hearings held pursuant to the Administrative Procedure Act." Furthermore, each assessor is required by Section 2323(B) to "follow the uniform guidelines, procedures, and rules and regulations in determining the fair market value of all property subject to taxation within his respective parish or district," and "[a]ny manual or manuals used by an assessor shall be subject to approval by the Louisiana Tax Commission or its successor agency."
Three approaches for determining fair market value are set forth in Section 2323(C), as follows: "The fair market value of real and personal property shall be determined by the following generally recognized appraisal procedures: the market approach, the cost approach, and/or the income approach." In utilizing the market approach, an assessor is required to "use an appraisal technique in which the market value estimate is predicated upon prices paid in actual market transactions and current listings." La. R.S. 47:2323(C)(1). In utilizing the cost approach, an assessor is required to "use a method in which the value of a property is derived by estimating the replacement or reproduction cost of the improvements; deducting therefrom the estimated depreciation; and then adding the market value of the land, if any." La. R.S. 47:2323(C)(2). In utilizing the income approach, an assessor is required to "use an appraisal technique in which the anticipated net income is capitalized to indicate the capital amount of the investment which produces the net income." La. R.S. 47:2323(C)(3).
Revised Statute 47:1837(D) requires: "In order to promote compliance with the requirements of the constitution and laws of the state, the tax commission shall issue and, from time to time, may amend or *165revise rules and regulations containing minimum standards of assessment and appraisal performance ...."3 In compliance with that responsibility, the Commission issued the following recommendation in 2009, in La. Admin. Code, Title 61, Part V, § 303(C), which provides:
In assessing affordable rental housing, the income approach is recommended. As defined in this Section, affordable rental housing means residential housing consisting of one or more rental units, the construction and/or rental of which is subject to Section 42 of the Internal Revenue Code ( 26 USC 42 ), the Home Investment Partnership Program under the Cranston-Gonzalez National Affordable Housing Act ( 42 USC 12741 et seq. ), the Federal Home Loan Banks Affordable Housing Program established pursuant to the Financial Institutions Reform, Recovery and Enforcement Act (FIRREA) of 1989 ( Public Law 101-73 ), or any other federal, state or similar program intended to provide affordable housing to persons of low or moderate income and the occupancy and maximum rental rates of such housing are restricted based on the income of the persons occupying such housing.
(Emphasis added.)
Notwithstanding the recommendation of La. Admin. Code, Title 61, Part V, § 303(C), that the income approach be employed by assessors in the valuation of affordable rental housing developments, the Assessor employed the market approach in his valuation of the Opportunity Homes property for the 2014 and 2015 tax years.
Paragraph (E) of La. Const. Art. VII, § 18, states that "[t]he correctness of assessments by the assessor shall be subject to review first by the parish governing authority, then by the Louisiana Tax Commission or its successor, and finally by the courts, all in accordance with procedures established by law." See also ANR Pipeline Company v. Louisiana Tax Commission , 02-1479, p. 5 (La. 7/2/03), 851 So.2d 1145, 1149 ("[C]orrectness challenges are subject to review under La. Const. Art. 7, § 18 (E) by the parish governing authority and the [Commission] before being reviewed by Louisiana courts ....") (footnote omitted).
"Judicial review of decisions of the [Commission] is authorized by La. R.S. 47:1998(A)(1) ; the extent of that review is governed by La. R.S. 49:964(F) and (G)of the Administrative Procedure Act." Panacon v. Louisiana Tax Commission , 97-2093, p. 4 (La. App. 1 Cir. 1/8/99), 747 So.2d 572, 573-74 ; Kansas City Southern Railway Company v. Louisiana Tax Commission , 95-2319, p. 3 (La. App. 1 Cir. 6/28/96), 676 So.2d 812, 815. See also La. R.S. 49:967(A) ("Chapter 13 [the Administrative Procedure Act] of Title 49 of the Louisiana Revised Statutes of 1950 shall not be applicable to the Board of Tax *166Appeals, the Department of Revenue, with the exception of the Louisiana Tax Commission that shall continue to be governed by this Chapter in its entirety, unless otherwise specifically provided by law ....").
Review is confined to the administrative record established before the Commission. See La. R.S. 49:964(F) ; Panacon v. Louisiana Tax Commission , 97-2093 at p. 4, 747 So.2d at 574. See also Metro Riverboat Associates, Inc. v. Louisiana Gaming Control Board , 01-0185, p. 7 (La. 10/16/01), 797 So.2d 656, 661 (holding that review of an administrative decision is limited to the administrative record and a district court may not receive evidence when sitting as an appellate court).
Pursuant to La. R.S. 49:964(G), the reviewing court may only reverse or modify the agency decision if substantial rights of the appellant have been prejudiced because the administrative findings, inferences, conclusions, or decisions are: (1) in violation of constitutional or statutory provisions; (2) in excess of the statutory authority of the agency; (3) made upon unlawful procedure; (4) affected by other error of law; (5) arbitrary or capricious or characterized by abuse of discretion or clearly unwarranted exercise of discretion; or (6) not supported and sustainable by a preponderance of evidence as determined by the reviewing court. The reviewing court shall make its own determination and conclusions of fact by a preponderance of evidence, based upon its own evaluation of the record reviewed in its entirety upon judicial review; however, when the agency had the opportunity to judge the credibility of witnesses by first-hand observation of demeanor on the witness stand and the reviewing court does not, due regard shall be given to the agency's determination of credibility issues. La. R.S. 49:964(G).
In its review of the Assessor's decision to apply the market approach, in this case, to value Opportunity Homes' affordable housing development, the Commission concluded that the Assessor erred in failing to utilize the recommended income approach. We first examine the administrative record established before the Commission to ascertain whether there was a preponderance of the evidence to support the Commission's conclusion.
The Commission stated in both of its August 6, 2015 written decisions that the "pre-filed" exhibits of the Assessor and Opportunity Homes were "entered into the record." Also, the Commission's staff appraiser,4 Randy Harrington, testified at the January 13, 2015 hearing before the Commission, and his written appraisals of the Opportunity Homes property for the 2014 and 2015 tax years, consisting of 27 pages each, were introduced into evidence.5
Mr. Harrington's appraisal reports described the property as an "LIHTC Rent Restricted Scattered Site Residential *167Housing Complex,"6 consisting of 32 buildings and 54 rental units, used as low income multi-family housing. With respect to the methodology used in his appraisals, each appraisal report stated:
The sales comparison approach will not be utilized in establishing an estimated market value in this report. The market for Low Income Housing Tax Credit (LIHTC) complexes differ[s] from typical residential investment properties, due to inherent restrictions on income return, and the inability of the property owners to sell the projects without the expressed approval of the federal government and then only after certain regulatory requirements have been satisfied. These government subsidized projects present circumstances not normally found in other similar commercial properties.[7 ]
* * *
The Income Approach to Value is the most reliable indicator of value for income producing properties and should be relied upon, when detailed financial income and expense is available and/or market data information is available. The income approach to value in this appraisal report will utilize the actual gross income, actual rents collected and expenses from the income/expense statements supplied by the taxpayer. Due to the restricted rents enforced on the subject property the Income Approach to Value is the only applicable approach utilized in the report.
* * *
The Sales comparison approach to value was not utilized in the analysis. There have been no sales of LIHTC properties that we were able to locate within the state. According to the information gathered for this assignment, these properties are not typically sold due to the regulations and restrictions associated with these type properties.
*168In addition to a location map, subject photograph, neighborhood, site and demographics statements, statements of project parameters and definitions, Mr. Harrington's appraisal reports also included his effective tax rate calculation, income analysis, reconciliation analysis, income and expense balance sheets provided by Opportunity Homes, and a statement of conditions and qualifications. Mr. Harrington certified in his appraisal reports that, for each tax year, the value of the Opportunity Homes property was $1,525,000. Mr. Harrington testified, during the January 13, 2015 hearing before the Commission, in support of his written appraisal reports.
None of the factual data that formed the basis for Mr. Harrington's 2014 and 2015 appraisals was directly contradicted by any evidence submitted by the Assessor. The only evidence presented to the Commission by the Assessor was "pre-filed" prior to the hearing and consisted of: (1) appeal documents for the 2014 tax year, consisting of three pages for each of the 32 housing units; one page was the Assessor's letter notifying Opportunity Homes of his appeal to the Commission and the other two pages were appeal documents for the 2014 tax year that were presented to the Commission, stating: the municipal address and square footage of each unit; the Assessor's 2014 tax year assessment; the amount per square foot utilized by the Assessor to calculate fair market value for each unit (ranging from $44.64 to $145.83 per square foot); a statement that the fair market value listed was "supported by comparable sales data;"8 and the Board of Review's valuation for each unit; (2) a 2010 article from The Appraisal Journal, entitled "Appraising Low-Income Housing Tax Credit Real Estate; and (3) a 2006 "Advisory Opinion 14" from The Appraisal Foundation. No other evidence was presented by the Assessor during the Commission hearing, and the Assessor called no witnesses during the hearing.9
The Assessor presented the Commission with no testimony or documentation to explain how he arrived at the assessment values for Opportunity Homes' 32 housing units, nor was any information revealed concerning the "comparable sales data" the Assessor used to support his valuations or whether the low-income housing tax credits were incorporated within that valuation.10 In contrast, the lengthy and detailed appraisals made by Randy Harrington explained that there were no sales of low income housing tax credit ("LIHTC")
*169complexes found within the entire state, which could be used as comparables to Opportunity Homes' LIHTC property. Mr. Harrington further explained that LIHTC complexes differ from typical residential investment properties because the rents are limited to below other rental property in the area, that sales of the LIHTC properties must be approved by federal government after regulatory requirements have been met, and that LIHTC properties are not typically sold because of the stringent regulations and requirements. However, because LIHTC properties are income-producing and financial data, including rents received and expense statements, are available, the income approach is the most reliable indicator of the value of such properties. Mr. Harrington further went into great detail as to how he derived the total fair market value of the Opportunity Homes LIHTC development, in the amount of $1,525,000 for both the 2014 and 2015 tax years.
It is important to keep in mind that a fair market value, as defined by La. R.S. 47:2321, supra, involves the determination of the highest price that a property could bring on the open market, which would be: (1) agreeable to a willing and informed buyer and seller; (2) under usual and ordinary circumstances; (3) allowing a reasonable time for finding a buyer with knowledge of all the legally available uses and purposes for which the property is best adapted. As applied in the case of the Opportunity Homes LIHTC properties, a well-informed buyer would be aware of all the federal regulations governing LIHTC properties, including the 30-year term during which the property would be rent-restricted to a minimum percentage of low-income tenants. Such impediments would negatively affect the value of the property and would render it so economically dissimilar to unrestricted and unregulated commercial property as to prohibit fair market value comparison. Because the market approach to determining fair market value, as stated in La. R.S. 47:2323(C)(1), involves the use of a comparison to "prices paid in actual market transactions and current listings" and there are no actual available market transactions involving LIHTC properties, it would be impossible to perform a market approach appraisal that produced an accurate fair market value for LIHTC properties.11
Thus, we conclude that the preponderance of the evidence supported the Commission's determination that the income approach was the appropriate method for determining the property values and that $1,525,000 was the correct fair market value for each tax year at issue. Having ruled on this basis, we find no need to address the remaining issues raised in the writ applications.
We find no conflict between La. R.S. 47:2323, providing parish assessors a choice of three generally recognized appraisal methods to utilize to determine fair market value (the market approach, the cost approach, and/or the income approach), and La. Admin. Code, Title 61, Part V, § 303(C), which recommends the use of the income approach for assessing affordable rental housing, such as the Opportunity Homes LIHTC development. This case turned purely on the facts established before the Commission, proving that the income approach was the more appropriate method for determining fair market value in this case. Consequently, the appellate court erred in holding that the Commission's *170decisions were in violation of statutory provisions, in excess of its authority, based upon unlawful procedures, and legally incorrect.12
DECREE
Accordingly, we reverse the appellate court rulings and reinstate the Louisiana Tax Commission decisions, modifying the Orleans Parish Assessor's assessments of the fair market value of the Opportunity Homes Limited Partnership property to $1,525,000 for both the 2014 and 2015 tax year.
