A Bank must not order, obtain, use, or pay for a second or subsequent appraisal in connection with a transaction unless: (i) a second appraisal is required by law or (ii) there is a reasonable basis to believe that the initial appraisal was flawed or tainted and such basis is clearly and appropriately noted in the file, or (iii) such appraisal is done pursuant to written, pre- established bona fide pre- or post-funding appraisal review or quality control processes or underwriting guidelines, and so long as the Bank adheres to a policy of selecting the most reliable appraisal, rather than the appraisal that states the highest value.
