A New Rulebook for How Your House Gets Valued
Starting November 2, 2026, every home appraisal submitted for a loan backed by Fannie Mae or Freddie Mac will have to follow an entirely new dataset and reporting format. The two mortgage giants are requiring appraisers to move to the Uniform Appraisal Dataset (UAD) 3.6, retiring the familiar 1004 form in favor of a single, dynamic Uniform Residential Appraisal Report, or URAR.
According to Freddie Mac’s own documentation, the change involves “replacing all existing GSE appraisal forms with a single flexible and dynamic report” that “covers all property types, improves the review process and reduces revisions.” Fannie Mae’s parallel guidance confirms the same November 2 mandate date.
What Actually Changes on the Form
The old paper-style forms forced appraisers to check boxes designed for a generic single-family home. The new URAR is built instead from discrete, repeatable data fields that adjust to the property being appraised. Photo requirements also shift, moving from a fixed checklist to categories of required, conditionally required, and optional images. Industry trade publication McKissock Learning describes it as the most significant overhaul of appraisal reporting in the current dataset era.
A Timeline Appraisers Have Been Working Against for Months
Freddie Mac’s own guidance shows compliance rules for the new dataset were released in mid-May, job aids for appraisers followed in June, and updated FAQs went out in August. Loans submitted after November 2 without a compliant UAD 3.6 appraisal are expected to face delivery problems.
Why This Matters Beyond the Appraisal Industry
Homeowners and buyers rarely think about the dataset behind their appraisal, but the format directly shapes what gets measured, photographed, and reported about their property, and by extension what number ends up backing their loan.
