Buying or selling a home comes with plenty of paperwork. And if you’ve heard your lender or real estate agent mention UAD 3.6, you might be wondering what it means for your transaction.
The name sounds technical, but the main idea is simple: appraisal reports are moving to a new format that collects and presents property information in more detail.
The change takes effect on 2 November 2026 for new appraisal submissions to Fannie Mae and Freddie Mac. Here’s what buyers and sellers should know before they get to that stage of the process.
1. What Is UAD 3.6?
UAD stands for Uniform Appraisal Dataset. It sets out how property information is collected and reported in appraisals submitted to Fannie Mae and Freddie Mac.
Previously, appraisers used different forms depending on the type of property. UAD 3.6 replaces those older forms with one flexible report that adapts to the property being appraised.
What does this mean for you?
The appraisal report will look different and include more detailed property information. You don’t need to learn the technical details, but understanding the basics can help you know what to expect.
2. When Does UAD 3.6 Take Effect?
The transition is happening in stages.
| Date | What It Means |
|---|---|
| 8 September 2025 | Early adoption began for a limited group of lenders and appraisers |
| 26 January 2026 | Broad production began, allowing both old and new formats |
| 2 November 2026 | UAD 3.6 becomes mandatory for new submissions to Fannie Mae and Freddie Mac |
| 3 May 2027 | The transition period for previously submitted UAD 2.6 appraisals ends |
If you’re buying or selling during the transition, you could encounter either format. Your lender can confirm which one applies to your transaction.
3. What’s Changing in Appraisal Reports?
The new format changes how property information is organised and reported.
Here are three things worth knowing.
A Different Report Layout
Instead of several property-specific forms, UAD 3.6 uses one standardised report that adapts to the property. The layout will look different from older appraisal reports, so don’t assume something is wrong just because the format has changed.
More Detailed Property Information
Appraisers will record more details about the property’s condition, features and other characteristics.
For example, information about finished and unfinished areas above and below ground is recorded in more detail. This helps create a clearer picture of the property being assessed.
More Information About Property Features
Features such as energy-efficient systems, renovations and other improvements may be documented in greater detail.
This is one reason it’s useful to keep records of significant work carried out on the property.
4. Does UAD 3.6 Affect Home Value?
This is probably the biggest question for sellers.
UAD 3.6 changes how appraisal information is reported, not the basic process of determining a home’s market value.
Appraisers still consider factors such as location, property condition, comparable sales and current market conditions.
The new format allows more detailed information to be recorded, but it doesn’t guarantee a higher appraisal. A renovated kitchen or energy-efficient system may be relevant to the assessment, but its effect on value depends on the property and the market.
5. What Sellers Should Do to Prepare
You don’t need to renovate your home just because appraisal reporting is changing. A few practical steps can help.
- Gather improvement records: Keep receipts, permits and details of major renovations or system replacements.
- List important features: Make a note of upgrades such as new windows, solar panels, heating systems or other significant improvements.
- Address basic maintenance: Take care of obvious repairs and safety concerns where practical.
- Make the property accessible: Ensure the appraiser can safely reach relevant rooms, systems and outbuildings.
- Respond to questions: If the appraiser requests additional information, provide accurate details through the appropriate process.
If you’re selling a rural property in Southwest Washington, also organise information about acreage, barns, workshops, equestrian facilities or other features that help explain what makes the property different.
6. What Buyers Should Know
If you’re buying a home, the main thing is to understand that a new report format doesn’t automatically mean a problem with the property or your purchase.
Keep these points in mind:
- The report may look unfamiliar. That’s expected as the new format is introduced.
- The appraisal may require more information. Your agent or lender can help clarify what’s needed.
- The value is still independently assessed. UAD 3.6 doesn’t guarantee that a property will appraise at the agreed purchase price.
- Stay in touch with your lender. Ask about the expected appraisal timeline and any requirements for your particular loan.
UAD 3.6 applies to appraisal submissions for Fannie Mae and Freddie Mac loans. Other loan programmes may follow different requirements, so check with your lender if you’re using FHA, VA or USDA financing.
Final Thoughts
UAD 3.6 is a change in how appraisal information is collected and presented. For sellers, it means keeping useful property records ready. For buyers, it means knowing that the report may look different and asking questions when something isn’t clear.
You don’t need to understand every technical detail to prepare for an appraisal. You just need to know what to expect and have the right people to guide you through the process.
