A Major Appraisal Change Is Coming November 2 — What Homebuyers, Sellers and Realtors Need to Know
Most homebuyers and sellers don’t spend much time thinking about the appraisal process.
Until the appraisal becomes a problem.
Beginning November 2, 2026, one of the largest changes to residential appraisal reporting in more than 15 years becomes mandatory for appraisals submitted to Fannie Mae and Freddie Mac.
It’s called UAD 3.6, and it will fundamentally change how residential appraisals are documented and delivered.
For most consumers, this won’t change the basic purpose of an appraisal. The appraiser is still developing an independent opinion of a property’s market value.
But the report itself — and the technology and data behind it — is changing considerably.
And because the transition occurs right in the middle of active real estate transactions, Realtors, buyers and sellers should understand what is happening before November 2 arrives.
First: What Is UAD 3.6?
For years, residential appraisers have worked with a collection of familiar appraisal forms.
A single-family residence might use one form. A condominium might use another. A 2–4 unit property another.
Many people in real estate recognize these by their form numbers: 1004, 1073, 1025, 2055 and others.
That system is being replaced.
Under UAD 3.6, the traditional collection of separate appraisal forms is replaced by a new Uniform Residential Appraisal Report, or URAR.
Instead of choosing among numerous fixed forms, the new report is dynamic. It changes depending upon the property and the appraisal assignment.
A condominium may generate condominium-related sections. A property with an accessory dwelling unit may require different information. A multi-unit property may generate still other fields.
The report is designed around the property being appraised rather than forcing many kinds of properties into predetermined forms.
Why Is This Happening?
Residential appraisal reports contain an enormous amount of information, but much of the existing reporting system was developed long before today’s mortgage technology.
UAD 3.6 moves significantly more appraisal information into standardized, structured data.
That distinction is important.
Instead of important property characteristics being buried in comments and lengthy appraisal addenda, more information can be captured in defined fields that lenders and appraisal systems can analyze electronically.
The goal is better consistency, clearer information and improved data quality.
Fannie Mae describes one of the fundamental changes as moving information away from free-form comments and into defined data elements whenever possible.
The terminology is changing, too.
For example, familiar appraisal terminology such as Gross Living Area (GLA) becomes Finished Area Above Grade. “Basement” becomes Below Grade, while “garage/carport” becomes Vehicle Storage.
Those changes may sound minor, but collectively they represent a significant redesign of the appraisal report.
November 2, 2026 Is the Important Date
The industry has actually been transitioning toward UAD 3.6 for some time.
Broad production began in January 2026, allowing lenders prepared for the new system to begin submitting UAD 3.6 appraisals.
But November 2, 2026 is the mandate date.
Beginning that day, new appraisal reports submitted through the Uniform Collateral Data Portal for loans intended for delivery to Fannie Mae or Freddie Mac must use UAD 3.6.
A newly submitted appraisal using the old UAD 2.6 format will receive a fatal error and an unsuccessful submission status.
There is an important distinction for transactions already underway.
A UAD 2.6 appraisal that was successfully submitted before November 2 may still be revised afterward during the transition period. But an old-format appraisal cannot simply be submitted for the first time after the deadline.
That distinction could become particularly important for transactions crossing the November 2 date.
Does This Mean Appraisals Are Going to Take Much Longer?
You’ve probably heard that they will.
The reality is more nuanced.
Cotality, one of the major technology providers serving the appraisal industry, recently addressed some of the misinformation surrounding UAD 3.6.
There undoubtedly is a learning curve.
Appraisers have new software, new terminology, new data fields and a new reporting process to learn. Lenders, appraisal management companies and technology vendors also have systems and procedures that must work together.
So some disruption during the transition would not be surprising.
But that does not mean the new appraisal system is inherently designed to make every appraisal substantially longer.
Many of the fields within the new report are conditional. They appear because something about that particular property requires them.
In other words:
More possible data fields does not necessarily mean more required information on every appraisal.
Over time, the increased use of structured data may actually make portions of appraisal reporting and lender review more efficient.
The short-term issue is therefore less about the design of UAD 3.6 and more about an entire industry becoming comfortable with a new way of doing something it has done largely the same way for many years.
Where Could Problems Occur?
This is where the change matters to realtors, buyers and sellers.
Imagine a purchase scheduled to close shortly after November 2.
The lender orders the appraisal. The appraiser is still becoming familiar with UAD 3.6. Perhaps the appraisal software creates an issue. Maybe additional property information is needed. Perhaps a report requires correction before it can be successfully submitted.
None of these issues necessarily means anything is wrong with the property.
But a two- or three-day appraisal delay can have consequences.
Loan documents can be delayed.
A scheduled signing can move.
The seller may have another purchase dependent upon the proceeds.
Movers may already be scheduled.
Rate-lock deadlines can become an issue.
The appraisal is only one component of a mortgage transaction, but it is a component that can affect nearly everything that follows it.
That is why transactions scheduled around the November 2 transition deserve some additional attention.
Realtors: Your Role May Become Even More Important
Real estate agents frequently provide appraisers with information that helps them understand property and the market.
With UAD 3.6, being prepared to provide accurate property information quickly may become even more valuable.
If an appraiser contacts an agent requesting information that seems different from what appraisers have requested in the past, don’t automatically assume something is wrong.
The new reporting system captures property information differently.
Responding promptly can help keep the appraisal — and therefore the transaction — moving.
For listings, this is also a good time to make sure relevant information about the property is readily available.
Permits, additions, accessory dwelling units, renovations, solar systems, unusual property characteristics and other features can become important pieces of the appraisal puzzle.
In markets such as the San Francisco Bay Area, where properties can include everything from Victorian homes and TIC conversions to condominiums, ADUs, multi-unit properties and homes with unusual layouts, accurate property information can be particularly important.
Buyers: Don’t Panic If Your Appraisal Looks Different
If you’re buying a home after the transition, the appraisal report may look very different from one you received several years ago.
Different doesn’t mean bad.
The new URAR is intended to present property information more dynamically, with structured data and photographs integrated into relevant portions of the report.
You may also encounter terminology you haven’t seen before.
None of this means the appraiser has suddenly changed the basic question being answered:
What is this property worth in the current market?
The methodology remains rooted in the appraiser’s analysis of the property, relevant market information and appropriate comparable sales.
Sellers: The Appraisal Still Matters Even Though It Isn’t Your Loan
Sellers sometimes view the appraisal as primarily the buyer’s problem.
In a financed transaction, however, an appraisal problem can quickly become everyone’s problem.
If an appraisal is delayed, the buyer’s loan may be delayed.
If the loan is delayed, the closing may be delayed.
And if the seller is purchasing another property, that delay can move into the next transaction as well.
Sellers and listing agents should therefore be particularly responsive to appraisal-related requests during the transition.
What UAD 3.6 Does NOT Mean
With major industry changes, rumors tend to travel faster than details.
So, let’s clear up several misconceptions.
UAD 3.6 does not mean every appraisal will suddenly take dramatically longer.
It does not mean every property requires an enormous amount of additional information.
It does not require an appraiser to use a tablet or mobile device during the property inspection.
And it does not change the fundamental purpose of the appraisal.
What changes is the structure, terminology, technology and data standards behind residential appraisal reporting.
That’s a major change — but a very different statement from saying the appraisal process is being completely reinvented.
What Should Buyers, Sellers and Realtors Do?
There is no reason to postpone a real estate transaction because of UAD 3.6.
There is, however, good reason to prepare.
For transactions expected to close in late October, November or shortly thereafter, communication between the lender, appraisal management company, appraiser and real estate agents becomes particularly important.
Order the appraisal promptly once the transaction allows it.
Respond quickly to requests for property information.
Make sure unusual property features are accurately documented.
And most importantly, don’t wait until closing week to discover there is an appraisal issue that could have been addressed earlier.
The Bigger Picture
UAD 3.6 is much more than a new appraisal form.
It represents the mortgage industry’s continued move toward structured, standardized and machine-readable property data.
That could eventually make it easier for lenders to identify inconsistencies, understand collateral risk and process appraisal information more efficiently.
But major technology transitions rarely happen without a learning curve.
For homebuyers and sellers, the best response isn’t fear.
It’s awareness.
And for Realtors and mortgage professionals, the objective should be simple:
Know what’s changing, prepare for the transition, communicate early and keep the appraisal from becoming the unexpected obstacle between a signed purchase agreement and a successful closing.
A Mortgage Broker’s Perspective
I’ve worked through many changes in residential lending over the years — new loan guidelines, new disclosure requirements, new underwriting systems and new appraisal rules.
Most transitions ultimately become routine.
The challenging period is usually the beginning, when everyone involved is learning the new process at the same time.
UAD 3.6 will likely be no different.
If you’re purchasing or selling property with financing and your transaction will cross the November 2 transition, ask your lender or mortgage professional about the appraisal process early.
A little preparation at the beginning of the transaction can prevent a much bigger conversation at the end.
