In developing an independent approved or recommended value, the review appraiser may reference any acceptable resource, including acceptable parts of any appraisal, including an otherwise unacceptable appraisal. When a review appraiser develops an independent value, while retaining the appraisal review, that independent value also becomes the approved appraisal of the fair market value for Uniform Act Section 301(3) purposes. It is within Agency discretion to decide whether a second review is needed if the first review appraiser establishes a value different from that in the appraisal report or reports on the property.
