Most people who commission a commercial appraisal never think about the step after it. But the report that arrives is one appraiser’s supported opinion, and there are circumstances where the reliability of that opinion needs independent examination.

That examination is an appraisal review, and it is a distinct professional assignment with its own standards.

It is a defined discipline, not a second opinion

Appraisal review has dedicated treatment in the Uniform Standards of Professional Appraisal Practice. Standard 3 governs the development of an appraisal review, and Standard 4 governs its reporting — parallel to the way Standards 1 and 2 govern real property appraisal development and reporting. The review standards are not discipline-specific; they apply to appraisal reviews across property types.

This matters practically. Standards 1 through 4 are the standards referenced by federal financial institution regulatory agencies in implementing Title XI of FIRREA. An appraisal review performed by a qualified appraiser under Standard 3 is not an informal opinion about whether someone else’s number looks right. It is a professional assignment with defined requirements, a documented scope of work, and a report the reviewer signs and certifies.

What a reviewer is actually asked to determine

Under Standard 3, the reviewer develops an opinion as to the completeness, accuracy, adequacy, relevance, and reasonableness of the work under review, consistent with the scope of the review assignment.

In practice that means examining:

  • Problem identification. Was the correct property identified, with the correct property rights, effective date, and intended use? An appraisal that answers the wrong question cannot be salvaged by good execution.
  • Scope of work. Was the scope sufficient for the assignment, and was it disclosed?
  • Highest and best use. Is the conclusion supported, and does the rest of the analysis follow from it? Errors here propagate through everything downstream.
  • Data. Were the comparables verified, genuinely comparable, and current? Were relevant transactions omitted?
  • Adjustments. Are they supported by market evidence or asserted? Unsupported adjustments are among the most common substantive defects.
  • Approaches to value. Were the applicable approaches developed, and is the omission of any approach explained?
  • Reconciliation. Does the final value follow logically from the indications, or does it sit outside them without explanation?
  • Internal consistency. Do the stated assumptions, the analysis, and the conclusion agree with one another?
  • Compliance and disclosure. Certification, extraordinary assumptions, hypothetical conditions, prior services disclosure.

A useful review identifies what is deficient, explains why it matters, and states whether the deficiency affects the credibility of the value conclusion. Many findings do not. A reviewer who treats every formatting inconsistency as a fatal flaw is not doing the client a service.

Desk review versus field review

Desk review is conducted from the report and supporting documentation without inspecting the property. It is the appropriate tool for verifying methodology, checking data and math, confirming USPAP compliance, and screening for issues. It is faster and less expensive, and for routine portfolio work it is usually sufficient.

Field review adds inspection of the subject property and typically the comparables. It is warranted when physical condition is genuinely in question, when the appraisal’s description of the property may not match reality, when the value is large enough to justify the cost, or when the review will be relied on in litigation or an enforcement context.

With or without a value opinion. A review can be limited to evaluating the work under review, or it can include the reviewer’s own opinion of value. This distinction is significant: where the reviewer develops an independent value opinion, the assignment includes an appraisal, and the applicable development and reporting standards apply in addition to the review standards. It is also the more expensive and time-consuming path. Clients should be explicit about which they want, because the deliverables are meaningfully different.

When a review is worth ordering

Lenders and credit committees. Regulated institutions need documented, independent evaluation of collateral appraisals. Review is a routine part of that framework — particularly for large loans, complex or special-purpose collateral, and appraisals prepared by unfamiliar firms.

Litigation. When opposing parties submit conflicting appraisals, a review can identify which analysis is better supported and where the disagreement actually originates. That is frequently more useful to counsel than a third competing value.

Partnership and shareholder disputes. Where one party commissioned the appraisal and another questions it, an independent review addresses the objection without either side simply hiring a friendlier appraiser.

Estate and trust administration. Fiduciaries owe duties to beneficiaries. Where an estate holds significant real property and beneficiaries have divergent interests, a review documents that the value relied upon was evaluated independently.

Property tax matters. Reviewing the appraisal district’s supporting analysis, or an opposing appraisal in an arbitration or district court proceeding.

Portfolio and internal audit. Institutions with many appraisals from multiple vendors use review to maintain consistent quality standards.

What a review is not

A few clarifications worth stating, because they come up regularly:

  • It is not a cheaper appraisal. A review with a value opinion involves the review analysis plus appraisal development. It is generally not less expensive than a new appraisal.
  • It is not a tool for obtaining a preferred number. A reviewer with a contingent interest in reaching a particular conclusion has an ethics problem, not an assignment. Reviews that survive scrutiny are the ones performed without one.
  • Disagreement is not a defect. Two competent appraisers can reach different values from the same market. The review question is whether the analysis is credible and supported, not whether the reviewer would have reached the same number.
  • It does not replace the original appraisal. Unless a value opinion is included, the review evaluates the existing work; it does not substitute for it.

Choosing a reviewer

Competence in the property type is the threshold requirement — USPAP’s Competency Rule applies to review assignments as it does to appraisals. A reviewer without meaningful experience in hospitality, senior living, refineries, or right-of-way work is not positioned to evaluate an appraisal of one. Independence from both the original appraiser and the outcome is equally non-negotiable, particularly where the review may be tested in a deposition or a hearing.
