The Uniformed Standards Professional Appraiser Practice (USPAP), requires appraisers to analyze all prior sales of the subject property within the past three (3) years for all types of real property (including one-to-four family), if such information is available in the normal course of business. Except under limited circumstances, a re-sale within 90 days of the last sale is not eligible for an FHA-insured Mortgage. The temporary waiver of FHA's regulation that prohibits the use of FHA financing to purchase single family properties that are being resold within 90 days of the previous acquisition, expired on December 31, 2014.
