Income Approach to Value

The income approach to value is based on the assumption that market value is related to the market rent or income that a property can be expected to earn. The income approach to value is required in the valuation of two-unit to four-unit properties. The income approach to value may not be appropriate in areas that consist mostly of owner-occupied properties because adequate rental data does not exist for those areas. However, USPAP requires the appraiser to develop and report the result of any approach to value that is necessary for credible assignment results. If the appraiser believes the income approach is necessary for credible assignment results, then the income approach must be included. Appraisals that rely solely on the income approach as an indicator of market value are not acceptable.

When the income approach to value is used, the appraisal report must include the supporting comparable rental and sales data, and the calculations used to determine the gross rent multiplier. If the appraiser has completed the income approach, the lender must thoroughly review the information provided to confirm that the appraiser’s analysis and comments for the income approach are consistent with comments mentioned elsewhere in the report.
