Appraisal & Property Requirements
4. Clearing Conditions on Existing Homes
All repair items required by the appraiser or underwriter must be inspected and the clearance documented.
A professionally licensed, bonded, registered engineer, licensed home inspector or appropriately registered/licensed trades person, as applicable, must provide documentation that all deficiencies have been acceptably corrected upon completion of repairs. "As applicable" has been determined to mean any individual who the lender deems to be qualified, which might be the appraiser.
Professionals as defined above may use their company's forms and letterhead to make the certifications. Appraisers and Compliance Inspectors are to use the Compliance Inspection Report, form HUD-92051. The individual signing Section II must be the person who actually performed the inspection. Section III or IV, as appropriate, is to be signed by the Direct Endorsement Underwriter.
