The appraisal forms most of the mortgage industry has read for two decades are being retired and consolidated into one dynamic report. Here is the timeline, the mechanics, and what actually changes for the people who read appraisals.
Last reviewed August 2026
The Uniform Appraisal Dataset is the common language Fannie Mae and Freddie Mac use to read a residential appraisal. It is not a form. It is the dictionary and the grammar: the list of fields, the permitted responses for each field, and the rules for how information gets recorded so a computer on the other end can parse it consistently. Version 2.6 has governed conventional residential appraisal reporting for years. Version 3.6 replaces it.
Fannie Mae describes the project as an effort to update the appraisal dataset, align it with current mortgage industry data standards (MISMO v3.6), and replace the GSE appraisal forms with a single data-driven, flexible, and dynamic appraisal report for any residential property type. That last clause is the part most people underestimate. The familiar forms are not being revised. They are being retired and folded into one redesigned Uniform Residential Appraisal Report that expands or contracts depending on what the property is and what the assignment requires.
The GSEs have run this rollout in phases rather than flipping a switch. A limited production period came first, with a controlled group of approved lenders and vendors submitting the new format alongside the legacy forms so integrations could be tested in live systems.
Broad production began January 26, 2026. Freddie Mac's published redesign timeline defines the window from January 26, 2026 through November 1, 2026 as the period in which a lender may submit either UAD 2.6 or UAD 3.6. Fannie Mae's broad production announcement puts it plainly: all lenders are now permitted to submit UAD 3.6 appraisal reports to UCDP. Permitted, not required.
On August 6, 2026, UCDP began returning warning messages on UAD 2.6 submissions, prompting users to transition. Warnings do not stop a file. They are the last polite notice.
November 2, 2026 is the mandate. The GSEs state that beginning on November 2, 2026, all new appraisal report submissions must be submitted to UCDP using UAD 3.6. After that date the portal will not accept a new report in the old dataset.
May 3, 2027 is the retirement milestone on Freddie Mac's timeline, described as the point at which the UAD 2.6 pipeline is cleared. Between the mandate and retirement there is a defined runway for cleaning up files that were already in flight.
This is the single most misread part of the mandate, and it is worth stating on its own. Freddie Mac's timeline is explicit that feedback messages are delivered based on UCDP submission date, not appraisal effective date.
So an appraisal I inspect and date in October 2026 is not automatically safe. If the lender does not push that file into UCDP until November 3, the portal evaluates it against the rules in force on November 3. In practice that means the decision about which dataset to use has to be made when the assignment is ordered, not when the report is signed. Any file with an effective date in the back half of October carries real transition risk if the lender's delivery pipeline runs slow.
Anyone who has worked around residential lending knows the report by its number. A 1004 is a full interior and exterior single-family appraisal. A 1073 is a condominium unit. A 2055 is exterior only. A 1025 is a two- to four-unit property. Those numbers are going away as separate documents.
Freddie Mac's UAD and forms redesign FAQ identifies the legacy reports the redesigned URAR replaces. The list covers the Uniform Residential Appraisal Report (1004 and Freddie's 70), the desktop and hybrid variants (70D and 70H), the individual condominium unit reports and their desktop and hybrid variants (1073 and 465, 1073D and 465D, 1073H and 465H), the exterior-only inspection reports (1075 and 466, and the 2055), the manufactured home report (1004C and 70B), the cooperative interest reports (2090 and 2095), the small residential income property report (1025 and 72), and the appraisal update and completion report (1004D and 442).
Two adjacent forms deserve a note. The single-family comparable rent schedule (1007 and 1000) is generally absorbed into the rental information section of the new URAR, with the legacy form completed separately only in rare cases where the original appraiser is not available to amend the report. The operating income statement (216 and 998) has been retired by the GSEs, and they do not expect to receive it through UCDP.
Replacing the form numbers does not eliminate the distinctions behind them. The redesigned URAR still supports traditional, exterior-only, desktop and hybrid assignments. The difference is that scope of work is now recorded as data inside one report rather than signaled by which piece of paper the appraiser reached for.
MISMO is the mortgage industry's data standard, maintained by the Mortgage Bankers Association, and MISMO v3.6 is the reference model UAD 3.6 aligns to. Freddie Mac notes that the GSEs built a subschema containing only the data elements needed to support the UAD 3.6 specification, so appraisal data travels in the same structural language as the rest of the loan file.
The practical consequence is that the deliverable is an XML data file with a PDF representation of the report, submitted through UCDP. Under the old regime the form was the artifact and the data was extracted from it. Under UAD 3.6 the data is the artifact and the readable report is generated from it.
For me as the appraiser, that changes how a report gets built. Free-text narrative that used to carry meaning has to become discrete, coded responses in defined fields. There is less room to explain something in a comment box and more obligation to record it where the system expects it. Good appraisal judgment still drives the value conclusion. The reporting simply has less tolerance for improvisation.
UCDP returns feedback on every submission. Warning severity means the file goes through with a flag. Fatal severity means it does not go through.
Fannie Mae's messaging update states that beginning November 2, 2026, all new UAD 2.6 submissions will receive a Fatal severity message, and that a fatal message produces a Not Successful UCDP status. There is no Submission Summary Report the lender can rely on and no successful delivery record.
A fatal result is not a valuation problem and it is not a criticism of the appraisal. It is a format rejection. The value conclusion could be perfectly well supported and the file still fails because it arrived in the retired dataset. The fix is not an argument with the portal. It is a report produced in UAD 3.6, which generally means the assignment gets rewritten in a compliant reporting platform rather than patched.
Almost every conventional loan in Fort Worth routes an appraisal through UCDP, so this is not an abstract IT concern. A rejected submission stalls a file, and in a purchase with a contract deadline on the calendar, a stalled file has consequences that have nothing to do with appraisal.
The transition would be unworkable if every correction to an older file forced a full rebuild, so the GSEs carved out an exception. Fannie Mae's messaging update states that after November 2, 2026, only revisions to previously submitted UAD 2.6 appraisal reports may be submitted, and that all new UAD 2.6 submissions will receive a Fatal severity message.
Freddie Mac's FAQ frames the same rule from the lender's side: revisions to UAD 2.6 reports may continue through the May 3, 2027 retirement date, and those revisions stay in the original dataset. The key word in both statements is previously. The exception applies to a report that already reached UCDP in UAD 2.6 before the mandate. It is not a side door for new work.
So if a lender comes back to me in December 2026 with a condition on an appraisal that was properly submitted in September 2026, that revision can be handled in the dataset it was born in. A brand new assignment ordered in December is UAD 3.6, full stop.
For lenders and AMCs, the work is operational and it is largely front-loaded. Loan origination systems, appraisal ordering platforms, review tools and quality control checklists all have to understand the new structure. Automated review rules written against 2.6 field positions do not transfer cleanly. Freddie Mac's own guidance to lenders is to confirm vendor readiness and system compatibility and complete GSE training rather than wait, and the reasoning is simple: a pipeline that discovers an integration gap in late October has no room to fix it.
For real estate agents, the visible change is that the report will not look like the grid you have been reading since you got licensed. The information you care about is still there. Gross living area, condition and quality ratings, the comparable sales and the adjustments are all still reported. They sit in a different layout, and the report may run longer because it expands to fit the property. If you are used to flipping to a known page number to find the adjustment grid, that habit will not survive the transition.
For homeowners, honestly, the change should be close to invisible. You will receive a copy of the appraisal because federal rules require the lender to give you one, and it will be a differently organized document. The analysis behind it does not change. The appraiser still inspects the applicable scope, researches sales, makes supportable adjustments and reaches a conclusion, and the report is still prepared in compliance with USPAP. What changed is the container, not the craft.
One thing I want to be careful about: nobody, including me, can tell you how a specific lender, AMC or automated review system will respond to any specific file. Readiness varies across the industry and these programs continue to change. What I can tell you is which dataset I am delivering and that I confirm platform capability before I accept an assignment.
November 2, 2026. Fannie Mae and Freddie Mac state that all new appraisal report submissions to UCDP on or after that date must use UAD 3.6. Freddie Mac's timeline notes that feedback is based on UCDP submission date, not appraisal effective date, so a late-October report delivered in November is judged by November's rules.
A Fatal severity message produces a Not Successful UCDP status. It says nothing about whether the value conclusion was well supported. It says the file arrived in a dataset the portal no longer accepts for new submissions.
Last reviewed August 2026. Fannie Mae and Freddie Mac update this program regularly, including the timeline itself. Verify current dates and requirements against the GSE pages linked in the sources below before you rely on anything here for a live transaction.
Not for every file yet. Broad production began January 26, 2026, and through November 1, 2026 a lender may submit either UAD 2.6 or UAD 3.6. Beginning November 2, 2026, the GSEs require all new appraisal report submissions to UCDP to use UAD 3.6.
Not by its effective date. Freddie Mac's timeline states that feedback messages are delivered based on UCDP submission date, not appraisal effective date. If the lender submits the report on or after November 2, 2026, it is evaluated under the mandate regardless of when the inspection happened.
Not as a separate report going forward. Freddie Mac's redesign FAQ lists the 1004 and 70 among the legacy forms the redesigned URAR replaces, along with the condominium reports, the exterior-only reports, the manufactured home report, the small residential income property report, the cooperative interest reports and the appraisal update and completion report.
Fannie Mae states that new UAD 2.6 submissions on or after that date receive a Fatal severity message, which results in a Not Successful UCDP status. The submission does not complete. Correcting it generally means producing the report in UAD 3.6.
Yes, within limits. Fannie Mae states that after November 2, 2026, only revisions to previously submitted UAD 2.6 appraisal reports may be submitted. Freddie Mac's FAQ indicates those revisions may continue through the May 3, 2027 retirement date and remain in the original dataset. The report must already have reached UCDP in UAD 2.6 before the mandate.
The separate forms do, but the assignment types do not. The redesigned URAR is built to support traditional, exterior-only, desktop and hybrid scopes within one dynamic report structure. Scope of work becomes recorded data inside the report rather than a different form number.
I cannot predict fees or turn times, and neither can anyone else, because they depend on the assignment, the property and the lender's own process. What I can say is that the new report requires more discrete data entry, and that appraisers and lenders across the industry are still absorbing that. Ask about scope and timing on the specific order rather than assuming.
Yes. It is organized differently and it may be longer, because the report expands to fit the property. The substance you would look for, including the gross living area, the condition and quality ratings, the comparable sales and the adjustments, is still reported. The analysis behind it has not changed.
