This is excerpt from Appraisal Modernization Act:
UNACCEPTABLE APPRAISAL PRACTICE.—The term ‘unacceptable appraisal practice’ means an appraisal report that— ‘‘(i) uses unsupported or subjective terms to assess or rate the property without providing a foundation for analysis and contextual information; ‘‘(ii) uses inaccurate or incomplete data about the subject property, the neighborhood, the market area, or any comparable property;
‘‘(iii) includes references, statements or comparisons about crime rates or crime statistics, whether objective or subjective; ‘‘(iv) relies in the appraisal analysis on comparable properties that were not personally inspected by the appraiser when required by the appraisal’s scope of work; ‘‘(v) relies in the appraisal analysis on inappropriate comparable properties; ‘‘(vi) fails to use comparable properties that are more similar, or nearer, to the subject property without adequate explanation; ‘‘(vii) uses comparable property data provided by any interested party to the transaction without verification by a disinterested party;‘‘(viii) uses inappropriate adjustments for differences between the subject property and the comparable properties that do not reflect the market’s reaction to such differences; or ‘‘(ix) fails to make proper adjustments, including time adjustments for differences between the subject property and the comparable properties when necessary. ‘‘(B) UNSUPPORTED.—The term ‘unsupported’ means, with respect to an appraisal report or an appraiser’s opinion of value, that the appraisal report or the opinion of value is not supported by relevant evidence and logic.’’.
DISCRIMINATION.—If the creditor has reason to believe that an appraisal report reflects discrimination, the creditor shall— ‘‘(i) order a subsequent appraisal, at the creditor’s own expense; ‘‘(ii) forward the appraisal report and the creditor’s summary of findings to the appropriate local, State, or Federal enforcement agency; and ‘‘(iii) upon a final determination of discrimination by the appropriate local, State, or Federal enforcement agency, receive a reimbursement from the appraiser covering the cost of the subsequent appraisal ordered by the creditor.
