What is the consequence of failing to keep an audit trail in valuations?

• A. It improves efficiency.
• B. It undermines defense against bias claims and USPAP compliance.
• C. It has no impact on appraisal credibility.
• D. It is optional for some types of valuations.

Answer: (B)

Auditable documentation creates traceability for the entire appraisal process—the data used, sources consulted, calculations performed, and the rationale for each adjustment. If that record isn’t kept, you can’t reliably defend the work against bias claims, nor demonstrate compliance with USPAP, because there’s no transparent path from data to conclusions. That lack of transparency calls the credibility of the appraisal into question with clients, reviewers, and any parties in dispute. Keeping an audit trail is not optional under USPAP; it supports credibility and defensibility. It does not improve efficiency; on the contrary, it protects the process and reduces risk.
