The mortgage industry is approaching an important milestone in the transition to Uniform Appraisal Dataset (UAD) 3.6. Beginning November 2, 2026, UAD 3.6 will be required for new appraisal report submissions to the Uniform Collateral Data Portal (UCDP®), unless an approved temporary policy exception applies. Fannie Mae and Freddie Mac, the government-sponsored enterprises (GSEs), have advised lenders to begin transitioning and to manage their pipelines carefully as the mandate approaches.
That date does not mean UAD 2.6 immediately disappears from every lender’s pipeline. Appraisal reports already submitted to UCDP in UAD 2.6 may still require corrections or revisions afterward. Those subsequent submissions remain in UAD 2.6 under the existing Document File Identifier (Doc File ID), because UCDP does not accept mixed UAD standards under the same Doc File ID. In addition, Federal Housing Administration (FHA), U.S. Department of Veterans Affairs (VA), and certain non-qualified mortgage (non-QM) programs may continue to support UAD 2.6 beyond the November GSE mandate.
For lenders, this creates a temporary but important operating reality. New production may be moving to UAD 3.6 while valid UAD 2.6 appraisals are still being reviewed, revised, and resubmitted. The challenge is not simply supporting two formats. It is making sure the appropriate standard stays connected to the appraisal throughout the process.
Why the Initial UCDP Submission Matters
As November 2 approaches, lenders need visibility into more than when an appraisal was ordered or completed. The UAD 3.6 mandate is based on the appraisal report’s initial UCDP submission date, not the loan application date or the appraisal’s effective date.
That makes pipeline management especially important. Organizations should understand which appraisal reports have already established a UAD 2.6 submission history and which are still moving toward their first submission.
For organizations that are technically and operationally ready, there is also value in moving new production to UAD 3.6 rather than waiting simply because dual-standard support remains available. Earlier adoption gives teams more opportunity to work with the redesigned report, validate internal processes and address questions as their UAD 3.6 volume grows.
The GSEs have also established a temporary policy exception process for lenders that need additional implementation time. That flexibility is important, but it does not change the broader direction of the industry. Dual-standard capability can provide continuity while organizations continue progressing toward UAD 3.6.
What Happens When a UAD 2.6 Appraisal Comes Back?
The overlap becomes especially relevant after the initial submission. Appraisals do not always move directly from completion to delivery. A report may need to be reviewed, corrected, revised and resubmitted.
If an appraisal was submitted to UCDP in UAD 2.6, revisions associated with that existing Doc File ID remain in UAD 2.6. A revision does not become a UAD 3.6 appraisal simply because it occurs after November 2.
That technical distinction has a practical consequence. When an appraisal comes back for additional work, the person handling it should not have to reconstruct its submission history to determine which standard applies. Wherever possible, that history should stay with the file and help guide the next step.
The GSEs have also clarified that the eventual retirement of UAD 2.6 submission functionality does not, by itself, prevent the sale of a loan supported by a valid UAD 2.6 appraisal, provided applicable GSE policies and appraisal validity requirements are met. This reinforces why lenders should distinguish between appraisal submission requirements and the broader lifecycle of the loan.
UAD 3.6 Changes More Than the Submission Format
UAD 3.6 is also more than a new version of an appraisal file. The redesigned standard replaces multiple legacy GSE appraisal forms with a single, dynamic Uniform Residential Appraisal Report (URAR) and introduces a more structured, data-driven approach to appraisal reporting.
That is why readiness extends beyond final delivery to UCDP. The appraisal has to be produced using the appropriate standard, move through quality control, address potential file or submission issues, and ultimately reach the correct portal in the correct format.
Looking at those steps together can also reveal where avoidable manual work still exists. Does someone need to determine which UAD standard applies every time a file returns? Are submission issues being found only at final delivery? Can appraisal history move with the file instead of being reconstructed later?
The goal is not to remove professional judgment from appraisal operations. It is to reduce process friction so that people can apply that judgment where it matters most.
How FHA Fits Into the Dual-Standard Environment
Organizations working across conventional and Federal Housing Administration (FHA) lending also need to account for separate implementation timelines. On October 1, 2026, FHA opened an optional broad production period for UAD 3.6 through the Electronic Appraisal Delivery (EAD) portal.
FHA-approved mortgagees may submit appraisals in UAD 3.6 while continuing to submit all or some appraisals in UAD 2.6. For a given FHA case number, the same UAD format used for the initial submission must be used for subsequent appraisal submissions for that case. FHA has said it will continue assessing mortgagee readiness before establishing and announcing a mandatory adoption date.
The GSEs and FHA are each moving through their respective implementation processes. For lenders working across both, the practical question is whether their systems and processes can recognize the requirements associated with each appraisal and support the appropriate path without creating unnecessary complexity for the people doing the work.
Supporting the Workflow, Not Just the Submission
A successful UAD 3.6 transition requires more than the ability to deliver a file to a portal. Appraisal fulfillment, quality control, pre-submission review and final delivery all play a role.
Veros Real Estate Solutions and Valligent are here to support organizations across both legacy appraisals and the new UAD 3.6 format for as long as dual workflows are needed. Valligent provides national appraisal management and UAD 3.6 appraisal fulfillment. VeroSCORE™ supports appraisal quality control for both UAD 2.6 and UAD 3.6. Submission Preview provides a pre-submission checkpoint to help identify potential issues, including fatal submission errors, appraiser licensing and UAD 3.6 compliance concerns, before an appraisal reaches UCDP or EAD. PATHWAY supports automated appraisal delivery to both portals, including UAD 2.6 and UAD 3.6 workflows.
Organizations can use these capabilities individually or together, depending on where support is needed. The broader objective is to help appraisal information move consistently from production through review and delivery while reducing unnecessary manual handoffs.
UAD 3.6 is where the industry is headed. The work immediately ahead is making that transition while maintaining continuity for appraisal reports that appropriately remain in UAD 2.6.
For lenders, the most useful question may be this: Can we continue moving toward UAD 3.6 while making the overlap as straightforward as possible for the people, systems and appraisal files moving through the process?
