4.1 Standard 3: Appraisal Review Development

Appraisal review is a specialized discipline within valuation practice that involves evaluating the quality and compliance of another appraiser's work. Under the Uniform Standards of Professional Appraisal Practice (USPAP), Standard 3 governs the development of an appraisal review assignment. Whether conducted for risk management, quality control, regulatory enforcement, or litigation support, appraisal reviews ensure that appraisal reports meet professional standards and provide reliable foundations for decision-making.

Purpose and Nature of Appraisal Review

Under USPAP, an appraisal review is defined as the act or process of developing an opinion about the quality of another appraiser's work that was performed as part of an appraisal or appraisal review assignment.

It is essential to understand the fundamental distinction between an appraisal and an appraisal review:

• Appraisal Assignment: The subject of the assignment is a specific asset (such as real property, personal property, or a business interest), and the objective is to develop an opinion of value.
• Appraisal Review Assignment: The subject of the assignment is the work under review (a written report, a workfile, or portions thereof), and the primary objective is to form an opinion regarding the quality, completeness, accuracy, relevance, and reasonableness of that work.

Reviewers do not automatically express their own opinion of value when conducting a review under Standard 3. A review can focus exclusively on assessing whether the original appraiser followed appropriate procedures, applied sound methodologies, and complied with applicable rules and regulations.

Problem Identification in Appraisal Review (Standards Rule 3-2)

Developing an appraisal review begins with thorough problem identification. Under Standards Rule 3-2, the reviewer must explicitly identify several key elements before determining the appropriate scope of work:

1. Client and Intended Users: Identifying who requested the review and any additional parties authorized to rely upon the review findings.
2. Intended Use: Establishing how the review report will be used—such as internal lender quality control, loan underwriting, litigation evidence, or state regulatory licensing investigations.
3. Reviewer's Purpose: Defining the precise objective of the review. The reviewer's purpose may be to evaluate technical compliance, verify factual data, judge the credibility of the value conclusion, or determine if the work conforms to USPAP or specific client guidelines.
4. Work Under Review: Identifying the specific document or portion of work being evaluated, including the appraiser(s) who authored the work, the date of the report, and the property involved.
5. Ownership and Property Identification: Identifying the real estate, personal property, or business interest described in the work under review.
6. Key Dates: Identifying three distinct dates critical to the assignment:
   • The date of the work under review (when the original report was completed).
   • The effective date of the opinion in the work under review.
   • The effective date of the reviewer's opinion (when the review judgment is rendered).

Scope of Work Determination (Standards Rule 3-1 & 3-2(d))

The Scope of Work Rule applies directly to appraisal review assignments. The reviewer must determine and perform a scope of work necessary to produce credible review results for the intended use. The scope of work in a review varies depending on the assignment requirements and client instructions.

Desk Review vs. Field Review

Appraisal review assignments generally fall into two broad categories based on the extent of inspection and data verification:

Evaluating Completeness, Accuracy, Relevance, and Reasonableness

Under Standards Rule 3-1, the reviewer must develop an opinion as to the quality of the work under review by systematically analyzing four critical dimensions:

1. Completeness

Does the report contain all necessary information, analyses, disclosures, and qualifying statements required by USPAP and assignment guidelines? The reviewer must verify that required components—such as highest and best use analysis, exposure time estimates, and signed certifications—are present.

2. Accuracy

Are calculations, mathematical operations, and factual statements accurate? The reviewer checks for calculation errors in adjustment grids, capitalization rate derivations, square footage calculations, and income multipliers.

3. Relevance

Are the data, analytical methods, and comparable properties selected relevant to the subject property and market area? For example, selecting comparable sales from a competing neighborhood when immediate subdivision sales exist may indicate poor relevance.

4. Reasonableness

Are the appraiser's assumptions, adjustments, qualitative reasoning, and final value conclusions logical and supported by market evidence? The reviewer assesses whether another qualified professional would arrive at similar conclusions based on the evidence presented.

Prohibition of Hindsight Bias

A central mandate of Standard 3 is that the reviewer must evaluate the work under review strictly in the context of market conditions and data available as of the effective date of the original appraisal.

Reviewers are strictly prohibited from using hindsight bias—criticizing the original appraiser based on market events, sales transactions, or economic changes that occurred after the effective date of the original appraisal. Information discovered after the effective date cannot be used to declare the original appraisal non-compliant or incompetent if that information was not reasonably available to the appraiser at the time the appraisal was conducted.

Reviewer Qualifications and Ethics

The Competency Rule applies fully to appraisal reviewers. To perform an appraisal review, the reviewer must possess:

• Geographic competence regarding the subject property's market area.
• Property-type competence for the specific asset class being evaluated (e.g., retail centers, agricultural land, industrial complexes).
• Methodological competence to understand and evaluate the approaches to value applied in the original report.

If a reviewer lacks the necessary knowledge or experience, they must disclose their lack of competency to the client, take all steps necessary to acquire competence, or associate with an appraiser who possesses the requisite expertise.

Furthermore, under the Ethics Rule, the reviewer must act with absolute independence, impartiality, and objectivity. Reviewers cannot act as advocates for any party, nor can their compensation be contingent upon finding fault with an appraisal report or supporting a specific review outcome.
