Major Mortgage Appraisal Changes Are Coming: What Buyers, Sellers, and Homeowners Should Know

If you have heard that appraisals are changing in 2026, the short version is this: the way appraisers document and report their findings is being redesigned — and if you are buying, selling, or refinancing, it is worth understanding what that means for your transaction before you are in the middle of one.

The change is called UAD 3.6. Some lenders are already using it. Beginning November 2, 2026, new appraisal submissions to the Uniform Collateral Data Portal (UCDP) — the system Fannie Mae and Freddie Mac use to receive appraisal data — must use the new format. That is a mandate for new submissions, not a closing deadline, and not the first time the format will appear in a transaction.

What Is Changing — and What Is Not

UAD stands for Uniform Appraisal Dataset. It is the standardized framework Fannie Mae and Freddie Mac use to collect and analyze appraisal data across the country. Version 3.6 replaces legacy appraisal forms — the 1004 for single-family homes, the 1073 for condos, and others — that have been in use for decades.

The central change is a redesigned appraisal report and standardized property data. The change itself does not automatically increase or decrease your home's value. Related appraisal-policy requirements also depend on the applicable loan program.

What is not changing: UAD 3.6 does not eliminate appraisal waivers or alternative valuation methods where those are already permitted by the applicable loan program. It does not change property tax assessments. It does not require existing homeowners to obtain a new appraisal.

This article addresses Fannie Mae and Freddie Mac requirements. FHA, VA, USDA, and jumbo loans are governed separately, and their applicable requirements and timelines require separate confirmation for those programs.

Impact on Buyers

For most buyers, the practical effect of UAD 3.6 will be in the level of detail an appraiser documents about the property — condition ratings, feature descriptions, neighborhood characteristics — captured in a more structured format than the legacy forms required.

A few things worth understanding before you write an offer:

Appraisal timelines may shift during the transition. Appraisers are learning a new reporting format, and some additional time for report preparation is possible, particularly in the months immediately following the November 2026 mandate. This is a possibility, not a certainty, and it is worth asking your lender whether they anticipate any effect on your transaction's timeline.

The new format does not guarantee a smaller appraisal gap or that the appraised value will match the purchase price. If you are buying in a competitive market, the same gap-management strategies apply: understand your contract terms, discuss your options with your lender before you are in escrow, and know what your choices are if the value comes in below the purchase price.

Your loan type matters. UAD 3.6 applies to appraisals submitted to Fannie Mae and Freddie Mac. Ask your lender which valuation method your specific loan requires and whether the new format applies to your transaction.

Impact on Sellers

Sellers should understand that UAD 3.6 increases the level of property documentation an appraiser will capture — condition, features, updates, and physical characteristics are reported in more granular detail than the legacy forms required.

This does not mean the new format will produce a higher value. Appraisers still determine value based on market data and comparable sales.

What it does mean practically: property access and accurate documentation of improvements matter for any appraisal. Make sure the property is accessible for the appraisal appointment, and work with your agent to compile a list of improvements and updates with approximate dates. That information can be provided to the appraiser as supporting documentation — not to influence the conclusion, but to ensure the report reflects what is actually there.

The new format does not guarantee a higher value or automatic support for the sale price.

Impact on Homeowners Refinancing

For a refinance, the value accepted by the lender helps determine your loan-to-value ratio — which can affect whether you qualify, how the loan is priced, and which programs are available to you. Not every refinance requires a traditional appraisal; some loan programs permit waivers or alternative valuation methods, and the applicable approach depends on your loan type and lender.

UAD 3.6 does not create equity, and it does not guarantee that a refinance appraisal will come in at a particular value.

If you are considering a refinance and your equity position is close to a qualifying threshold, the most useful step is a preliminary review of your loan options before ordering an appraisal. That review can clarify which valuation method applies to your situation and what the realistic range of outcomes looks like.

Will My Appraisal Cost More?

This is a reasonable question, and the honest answer is that we do not have a verified nationwide dollar or percentage increase attributable to UAD 3.6. The new format requires more detailed data collection and reporting, and some appraisers may adjust their fees to reflect additional work. Whether and how that affects what a borrower is quoted depends on the appraiser, the appraisal management company involved, the lender, and the property.

It is also worth understanding that the total appraisal-related charge on your Loan Estimate may include more than the appraiser's own fee — management fees, technology fees, and other related charges can be part of the total. The amount charged to the borrower may differ from the appraiser's compensation. Ask your lender what the quoted charge includes and whether any additional charges could apply.

Before your appraisal is ordered, ask:

• What is the total quoted appraisal charge for my property?
• Does it include management, technology, or other related fees?
• Could rush service, property complexity, or a required follow-up inspection add to the cost?

What to Do Now

Whether you are buying, selling, or refinancing, here are the questions worth getting clear answers on before your transaction is underway:

• Which valuation method does my loan require? (Traditional appraisal, appraisal waiver, hybrid, or desktop — and does UAD 3.6 apply to that method?)
• Will this appraisal use the new UAD 3.6 reporting format? (Relevant for transactions with appraisal submissions on or after November 2, 2026.)
• What property information or access will the appraiser need? (Especially for condos, multi-unit properties, or homes with recent improvements.)
• What is the total quoted appraisal charge, and what does it include?
• Does your team anticipate any effect on my transaction's timing or cost?
• What are my options if the appraised value comes in below expectations?

No one needs to rush to close before November 2, 2026 solely because of this format change. But if you have an active transaction or are planning one, it is worth a conversation with your lender now — before the appraisal is ordered, not after.
