The next time you buy a home or refinance, the appraisal report backing your loan will look different — and that's good news. Starting November 2, 2026, Fannie Mae and Freddie Mac require appraisals submitted to the Uniform Collateral Data Portal to use the new UAD 3.6 format, the biggest change to appraisal data in over a decade (ICE Mortgage Technology).
The shift replaces decades-old static appraisal forms with a single, data-driven report built around objective property information instead of subjective judgments. For homebuyers and homeowners, that means appraisals that are more consistent, easier to review, and harder to skew by bias or gut feeling.
What is UAD 3.6?
UAD stands for Uniform Appraisal Dataset, the standardized framework Fannie Mae and Freddie Mac use to report property information in appraisals. UAD 3.6 is the latest version of that framework, redesigned to collect property data in a more detailed, consistent way (First Home Mortgage).
The old system relied on separate static forms for different property types, each one a paper-style grid an appraiser filled in by hand. UAD 3.6 replaces those with a single data-driven appraisal report that adapts to the specific property being appraised — a condo gets one set of relevant fields, a detached single-family home gets another. The result is a report that is dynamic rather than fixed, showing only the information that actually matters for the home in question.
Why is the appraisal changing?
The appraisal forms the industry has relied on haven't been meaningfully updated since 2010, while how property data is collected and used has moved on. UAD 3.6 aligns appraisal reporting with the MISMO reference model — the modern mortgage industry data standard — and replaces static GSE forms with a single, flexible report (ICE Mortgage Technology).
The two government-sponsored enterprises have worked on the redesign since 2018, gathering input from across the industry to update the dataset, match current data standards, and build one report that works for any residential property type (Fannie Mae).
How does the change benefit homebuyers and homeowners?
For consumers, the payoff is fairer, more consistent appraisals. The new standard tightens how appraisers rate a home's condition and quality, replacing loose, subjective descriptions with structured, consistent categories. That directly reduces the risk of inflated or undervalued estimates, which matters when your home's appraised value can make or break a purchase or refinance (MeridianLink).
Because the data is standardized, lenders can review appraisals faster and with less manual back-and-forth. Fewer revisions and shorter review cycles mean less delay in closing on your home (ICE Mortgage Technology). And with one dataset spanning all property types instead of separate legacy forms, the same consistent framework applies whether you're buying a condo or a single-family house.
When does UAD 3.6 take effect?
The transition is already underway, with a few key dates. January 26, 2026 opened the broad production period, letting all lenders begin submitting UAD 3.6 appraisals voluntarily. On November 2, 2026, UAD 3.6 becomes mandatory for all new appraisal reports submitted to the Uniform Collateral Data Portal (First Home Mortgage).
If your loan's lender has received a temporary policy exception from Fannie Mae and Freddie Mac, that lender can keep submitting older UAD 2.6 appraisals through May 19, 2027. From May 20, 2027, UAD 3.6 is mandatory for everyone. For most borrowers, none of this changes what you need to do — the format your appraisal uses is decided by your lender's requirements, not by you (Louisiana REALTORS).
Does a new format mean a different appraisal?
No — what changes is the way appraisal information is collected and reported, not the purpose of the appraisal itself. An appraisal still delivers an independent professional opinion of a property's market value, and it still helps your lender evaluate the home as collateral for your mortgage (First Home Mortgage).
What you may notice is a report that looks and reads differently than the old forms — more detailed property information, structured in a more consistent way. For many buyers and sellers, that's the most visible change: a different-looking document, not a different process.

UAD stands for Uniform Appraisal Dataset, the standardized framework Fannie Mae and Freddie Mac use to report property information in appraisals. UAD 3.6 is the redesigned version of that framework.
2Do homebuyers need to do anything differently?
You don't need to take special action. Just know your appraisal report may look different than older ones, and ask your lender if anything is unclear.
3Does UAD 3.6 change the purpose of an appraisal?
No. The purpose of an appraisal — an independent professional estimate of a property's market value — stays the same. Only the way the information is collected, structured, and reported is changing.
What does UAD 3.6 change about how an appraisal is done?
Three practical changes stand out. First, the report is more flexible: it adapts to the specific property and assignment rather than forcing every home onto the same static form, so a condo appraisal captures the fields that matter for condos and a single-family appraisal captures its own (First Home Mortgage). Second, property data is more standardized, with consistent definitions and a common reporting structure. Third, the new format captures more detailed property information, giving appraisers additional ways to record the characteristics of a home.
That last point deserves emphasis. Because the report collects richer, more structured data, an appraiser has fewer places to rely on vague, subjective language. The result is an appraisal backed by verifiable facts — square footage, condition ratings, comparable sales — rather than impressions. When a home's value is what determines whether your loan goes through, having that evidence clearly documented is a real safeguard.
What should you do to prepare?
For most borrowers, the honest answer is: nothing special. You don't choose the appraisal format — your lender's assignment requirements do — and you don't need to become an expert to read the new report (First Home Mortgage).
What helps is simply knowing the change is coming so a new-looking report doesn't surprise you mid-transaction. If you're buying or refinancing soon, here are a few practical steps:
Expect a different document. The report may be longer and more detailed, with property information organized in a new structure.
Ask questions. Your lender and real estate agent can walk you through anything that looks unfamiliar.
Keep your property presentable for inspection. A more detailed report means the appraiser's inspection can be more thorough, so an organized, well-maintained home makes a stronger impression.
None of this changes the fundamentals of buying a home — it just modernizes how one part of the process documents its work.
The bottom line for homebuyers and homeowners
UAD 3.6 is, at heart, a move from trusting the expert's gut to trusting verified data. For consumers, that translates into fairer, more consistent appraisals that are easier to review and harder to distort by bias or a loose judgment call.
You won't need to fill out new forms, learn new terms, or change how you shop for a home. Just be ready for an appraisal report that looks different, and lean on your lender when you have questions. A more data-driven appraisal benefits everyone in the transaction — and that's the welcome news behind the November 2 deadline.
You don't need to understand UAD 3.6 to benefit from it. If you're buying or refinancing, your lender handles the format — your job is simply to know that a new-looking appraisal report is normal after November 2, 2026.
