Creates a federal, publicly searchable database of residential real estate appraisals and appraisal data, and gives mortgage applicants a new consumer right to seek reconsideration of an appraisal’s value or request a subsequent appraisal under specified rules. Federal housing agencies must submit past and ongoing appraisal data for publication; creditors and appraisers must follow new procedures for handling reconsideration/subsequent appraisal requests, maintain records, and in some cases pay for follow-up appraisals. The Federal Housing Finance Agency must issue a final implementing rule within one year.
