Can an appraiser refuse a client's request to correct a factual error in an appraisal report?

No, not when the report contains a genuine factual error. The Uniform Standards of Professional Appraisal Practice (USPAP) treat making false or misleading statements and communicating misleading reports as potential violations, so an appraiser cannot knowingly leave inaccurate facts in a report. Appraisal independence rules under section 129E of the Truth in Lending Act protect the appraiser from pressure to change a supported value conclusion. A consumer who believes an appraisal is inaccurate can request a reconsideration of value from the lender with supporting evidence.
