Appraisal Review, Quality Control, and Risk Management
Review is an independent examination of another appraiser's work to determine whether it is credible, reasonable, and compliant. Know the review types: administrative (completeness and compliance), technical (methodology and analysis), and field (inspection-based verification). A reviewer may conclude the original value is reasonable, unreasonable, or develop an independent opinion - but must document the basis either way.
Apply a structured review: check the assignment and scope, verify the value definition and effective date, test the data, recompute the math, assess the reasoning, and evaluate reporting. Recompute rather than trust - a transposed digit in NOI is a classic finding.
Quality control is preventive: engagement acceptance, competence checks, conflict screening, peer review, documentation standards, and file retention. Risk management identifies and mitigates exposure: scope creep, unsupported assumptions, contingent pressures, data gaps, and reliance on unverified client information. Document the reasoning contemporaneously; a file reconstructed after a complaint is weak evidence.
Worked example: a review finds the report used a 6% cap rate from a low-risk comparable for a high-risk subject. The reviewer does not merely flag the rate - the reviewer tests whether the risk mismatch materially changes the conclusion and documents the effect.
Traps: a reviewer substituting personal preference for an objective standard; treating a technically compliant but unsupported conclusion as acceptable; and reviewing only the final number instead of the analysis chain.
