Summary
Fannie Mae and Freddie Mac's UAD 3.6 appraisal-data mandate takes effect November 2, 2026 for new UCDP submissions. Legacy UAD 2.6 submissions ordinarily fail unless the lender obtains a GSE-specific temporary exception. Previously submitted UAD 2.6 reports may still be revised; FHA's separate transition remains optional.
A new appraisal-data requirement is now in force for lenders selling loans to Fannie Mae and Freddie Mac. Beginning Monday, November 2, newly submitted appraisal reports must use Uniform Appraisal Dataset 3.6 unless a lender has obtained a temporary exception from the applicable government-sponsored enterprise.
The change is enforced through the Uniform Collateral Data Portal (UCDP), the shared submission system used by the two companies. New reports sent in the older UAD 2.6 format receive a fatal message and a “Not Successful” status. That is a submission failure, not an appraisal finding that the property is overvalued or otherwise deficient.
There are important qualifications. Revisions to a UAD 2.6 report first submitted before the deadline remain permissible, and lenders granted policy exceptions can continue to use the older format during a defined transition period. The rule applies according to the date the appraisal is first submitted to UCDP, Freddie Mac explains, rather than the loan application date or the appraiser’s effective valuation date.
What changes in the appraisal file
UAD 3.6 replaces a collection of familiar static appraisal forms with the Uniform Residential Appraisal Report, a dynamic report built from structured data. The file delivered to UCDP is a ZIP package containing the report’s XML data, a PDF rendering and associated images. Fannie Mae’s portal guidance sets out the packaging requirements.
That means the conversion affects considerably more than the appraiser preparing the valuation. Appraisal management companies, lenders’ ordering systems, appraisal software, review teams and delivery technology must all handle the new data consistently. A lender whose vendor can generate the new report may still encounter problems if downstream quality-control or delivery systems cannot read it correctly.
Fannie Mae and Freddie Mac opened broad production on January 26, allowing lenders to submit either format while they prepared. Warning messages began appearing on legacy submissions in August. The November 2 cutoff is the next stage of that published implementation schedule, rather than an overnight change announced this week.
The exception is available, but it is not automatic
Both enterprises now offer a temporary policy exception for sellers that cannot complete their conversion in time. A lender must request an exception from each GSE to which it needs to deliver loans; an accommodation from one company does not automatically cover the other. The Fannie Mae lender letter and Freddie Mac’s updated FAQs describe the process.
Under Fannie Mae’s published timeline, approved lenders can continue using UAD 2.6 through February 28, 2027 without the additional reduced-functionality consequences that follow. From March 1 through May 19, legacy submissions under the exception remain possible, but Fannie Mae assigns a Collateral Underwriter risk score of 999 and removes specified appraisal-and-value representation-and-warranty enforcement relief for affected loans. Starting May 20, new UAD 2.6 reports are no longer accepted; support for the old format is scheduled to end June 28.
Those are Fannie Mae’s stated transition terms. Sellers should consult the applicable Freddie Mac exception and delivery instructions rather than assume every operational consequence is identical.
WRE News covered the exception when it was announced September 30. Today’s development is the effective date of the submission mandate. There is no verified evidence in the reviewed agency materials of how many lenders obtained exceptions or how many submissions failed on the first day.
FHA loans follow a different schedule
The Federal Housing Administration is adopting UAD 3.6, but its program has not made the format mandatory on November 2. In FHA INFO 2026-23, issued October 1, the agency opened optional broad production to approved forward and reverse mortgage lenders. They may continue submitting UAD 2.6 reports through FHA’s separate Electronic Appraisal Delivery portal until the agency announces its own required-use date.
For FHA cases, the format selected for the first appraisal submission must remain consistent in subsequent submissions for that case. The distinction matters for lenders and appraisal firms handling both conventional and FHA production: one workflow may now be compulsory while another remains elective.
What lenders should watch next
UCDP submission acknowledgments, vendor validation errors and the approval status of any requested exceptions are the immediate operational checks. Appraisal departments also need to distinguish a legacy report being revised from a report being submitted for the first time, because the two are treated differently.
The agencies have published technical guidance and support resources, but they have not released a first-day industrywide failure rate. Any claim that the transition has already disrupted closings would require actual lender or portal evidence. The immediate, confirmed change is that a new reporting standard now governs most newly submitted conventional appraisal files.
