On November 2, 2026, the home appraisal report that lenders, buyers, and appraisers have used for more than twenty years officially retires. In its place comes UAD 3.6, a completely redesigned appraisal standard from Fannie Mae and Freddie Mac that has been in development since 2018. If you buy, sell, or refinance a home after this fall, your appraisal will look different, read differently, and carry far more detail than anything that came before it. Here is what is changing, why it took two decades, and what it means for you.
What Is UAD 3.6?
UAD stands for the Uniform Appraisal Dataset, the standardized set of data definitions that Fannie Mae and Freddie Mac require for every appraisal on a loan they purchase. Think of it as the common language of home appraisals. When an appraiser describes a property's condition, quality, or features, the UAD defines exactly which terms and values they can use so that every report means the same thing to every reader.
UAD 3.6 is the newest version of that language, and it arrives alongside a fully redesigned Uniform Residential Appraisal Report, or URAR. The URAR is the actual report an appraiser completes when they value a home. The version being replaced, known to the industry as Form 1004, has remained largely unchanged since 2005. The phone in your pocket has been reinvented a dozen times since then. The document deciding whether your home supports your loan amount has not.
The two changes travel together. UAD 3.6 is the data standard, and the new URAR is the report built on top of it. Most industry coverage uses the terms interchangeably, and for practical purposes they describe the same event: the biggest overhaul of home appraisal reporting in a generation.
If you want a refresher on how the current process works before diving into what changes, our Home Appraisals 101 guide covers the fundamentals.
Why a Form Designed in 2005 Had to Go
The old appraisal system was not one form. It was a stack of them. A single family home used Form 1004. A condo required Form 1073. A manufactured home needed Form 1004C. A small rental property called for Form 1025, and an update or completion inspection meant yet another document, Form 1004D. Each form was a static template with fixed boxes, and when a property did not fit the boxes, appraisers squeezed their explanations into free form addendum pages bolted onto the back of the report.
That structure created real problems. Important commentary lived in unstructured text that computers could not reliably read and busy underwriters could sometimes miss. Condition ratings blended the interior and exterior of a home into a single grade, so a house with a pristine yard and a gutted kitchen could look average on paper. And because each property type had its own form, lenders and appraisers maintained parallel processes for what was fundamentally the same job.
Fannie Mae and Freddie Mac, the two government sponsored enterprises that buy the majority of American mortgages, launched the redesign initiative in 2018 with input from appraisers, lenders, and software providers. The goal was a report that captures what appraisers actually observe, in a format both humans and underwriting systems can fully use.
That goal shaped every decision that followed.
One Dynamic Report Replaces the Entire Stack of Forms
The most visible change is structural. All of those legacy forms, including the 1004, 1073, 1004C, 1025, and their companions, disappear on November 2. They are replaced by a single, dynamic URAR that adapts itself to the assignment.
Dynamic means the report is built from the data rather than the data being forced into a fixed template. If the property is a condo, condo specific sections appear. If it is a manufactured home, the report expands to include the details that matter for that property type. If the assignment is a desktop or exterior only appraisal, where the appraiser does not walk through the home, the report reflects that scope automatically. Sections that do not apply to a given property simply never appear, and there are no form numbers at all in the new world.
Commentary moves too. Instead of a wall of narrative text in an addendum, the appraiser's explanations now sit directly beside the data they support. If an appraiser adjusts a comparable sale for its larger lot, the reasoning appears right there with the adjustment. For anyone who has flipped back and forth through a 30 page appraisal PDF trying to match comments to line items, this is a welcome change.
Under the hood, the report is also fully digital. Appraisals are delivered as structured data files along with the familiar PDF and property photos, which means every field in the report can be analyzed automatically the moment it is submitted. That matters more than it sounds, and it connects directly to the databases we will cover shortly.
What the New Report Actually Captures
The redesigned URAR does not just reorganize old information. It collects meaningfully more of it.
The clearest example is the split between interior and exterior ratings. Under the old system, a home received one overall condition rating and one overall quality rating. UAD 3.6 separates them, so the inside and outside of a home are each graded on their own merits. The report also tracks condition at the component level, meaning the roof, the kitchen, the bathrooms, and other major elements can each carry their own status, including whether and when they have been updated.
New fields reach into areas the old form never touched. Appraisers can now document energy efficient features, disaster mitigation measures like storm shutters or reinforced roofing, broadband internet availability, and ceiling height categories. Sellers who have invested in a renovated kitchen or a new roof should appreciate this shift, because those improvements now have a dedicated, structured place in the valuation record instead of depending on a line of narrative an underwriter may or may not weigh. If you are preparing to sell, this pairs naturally with understanding how a comparative market analysis works, since both documents are ultimately about translating your home's features into value.
For buyers, the payoff is a report you can actually read. One of the stated goals of the redesign was consumer readability, and the new URAR opens with a summary section written in plainer language than the dense grid of the old 1004. You paid for the appraisal. Now the report is written with you in mind, not just your lender.
The Rollout Timeline
The transition has been underway for over a year, moving through deliberate phases:
- September 8, 2025: Limited production began. A small group of lenders and appraisers started submitting UAD 3.6 reports in real transactions.
- January 26, 2026: Broad production opened. Any lender may now submit appraisals in either the old UAD 2.6 format or the new UAD 3.6 format. This is the window we are in today.
- November 2, 2026: The mandate. Every new appraisal submitted to the agencies must use UAD 3.6. The legacy forms are retired for new conventional work.
- May 3, 2027: Final retirement of UAD 2.6. Until this date, appraisers can still submit revisions to old format reports that were originally delivered before the mandate.
One detail worth understanding: the deadline is based on when the appraisal is submitted to the agencies' portal, not when you applied for your loan. A loan application from October with an appraisal submitted in November falls under the new requirement. Lenders are planning their cutovers earlier than November 2 for exactly this reason, so expect the new report to become the norm this fall rather than on the deadline itself.
The mandate applies to conventional loans sold to Fannie Mae and Freddie Mac. FHA has begun accepting the new format on an optional basis and is expected to follow with its own requirement, while VA and USDA are on their own schedules. Since conventional loans make up the majority of the market, November 2 is the date that matters for most borrowers.
The Databases Behind the Change: Collateral Underwriter and Loan Collateral Advisor
To understand why the agencies care so much about structured data, you need to know what happens to an appraisal after it is submitted.
Since 2012, every appraisal on a loan sold to Fannie Mae or Freddie Mac has flowed through a shared electronic gateway called the Uniform Collateral Data Portal, or UCDP. From there, each agency runs the report through its own analytical engine. Fannie Mae's is called Collateral Underwriter, or CU. Freddie Mac's is Loan Collateral Advisor. Both tools compare the incoming appraisal against enormous historical databases, and both return a risk score to the lender within moments of submission.
The scale here is remarkable. Fannie Mae's Collateral Underwriter draws on a database of more than 70 million appraisals, which lets it check an appraiser's comparable sales, adjustments, and ratings against how the same properties and neighborhoods have been described in every prior report. If an appraiser rates a home's condition differently than the last three appraisals of that same house, the system notices. If the chosen comparables look weaker than alternatives the database knows about, the lender gets flagged. Appraisals that score well can earn the lender relief from certain repurchase risk, which is a strong incentive for quality.
These databases are also what power appraisal waivers, where the agencies have enough confidence in their existing data on a property to approve a loan without a new appraisal at all. If you have ever wondered how a lender could skip the appraisal on a refinance, this is the machinery behind it, and we cover that scenario in Can I Refinance Without an Appraisal?
UAD 3.6 supercharges this entire system. Every new data field, from component level condition to energy features, feeds these engines with cleaner and richer information. The old form fed the databases a blurry picture. The new one delivers high resolution.
Why Some Appraisers Are Dreading November 2
Not everyone in the industry is celebrating. The appraisal profession skews older, and for an appraiser who has completed thousands of reports on the 1004, the new URAR means relearning the core tool of their trade in their final working years. Industry trainers report that when they ask a classroom of appraisers whether the transition has them considering retirement, anywhere from 15 to 50 percent raise their hands, though most reconsider once they have completed training on the new system.
The complaints are not just about change for its own sake. The new report replaces much of the old free form writing with structured selections, and appraisers describe early assignments taking noticeably longer as they learn the new workflow. Rural appraisers have voiced particular concern, since the granular data the new form requests can be hard to source in markets with thin sales records. Appraisal software platforms are being rebuilt at the same time, which adds a second learning curve on top of the first.
Most industry observers expect the friction to be temporary, following the same arc as past technology transitions: slower at first, faster once the muscle memory forms. But the timing creates a practical consideration for borrowers. In the weeks surrounding November 2, some appraisers will be slower than usual, some will have left the field, and lenders working with unprepared appraisal panels may see delays.
That is a moment when the structure of your lender matters. Because CapCenter handles mortgage, realty, and insurance under one roof, the loan team and the real estate team work from the same timeline on every transaction, and the appraisal is ordered and tracked as part of one coordinated process rather than handed between separate companies. When an industry wide transition introduces friction, that coordination is the difference between a hiccup and a missed closing date.
What This Means for You as a Buyer, Seller, or Homeowner
For all the industry turbulence, the borrower's experience mostly improves. Buyers get an appraisal report that is easier to read and understand, with a clearer summary of how the appraiser arrived at the value. Sellers get a valuation framework that formally credits updates and improvements instead of burying them in narrative. Homeowners refinancing get the same benefits, plus a data ecosystem that over time should make appraisal waivers more accurate and more available.
Nothing about how your home's value is determined fundamentally changes. The sales comparison approach, where your home is measured against recent nearby sales, remains the heart of residential appraisal. The appraiser still visits or observes the property, selects comparables, and supports an opinion of value. What changes is how thoroughly that work is documented and how effectively it can be verified.
There is one cost dynamic worth watching. Some appraisers argue the new report requires more time and more data resources, and some may raise fees during the adjustment period. Appraisal fees are typically a few hundred dollars and are one of the third party costs borrowers traditionally pay at the start of a loan. This is also where CapCenter's ZERO Closing Cost model changes the math in your favor, since eliminating lender fees and third party closing costs takes thousands of dollars of transition era uncertainty off your side of the table entirely.
If you are curious what the new report actually looks like, Fannie Mae and Freddie Mac have published sample versions of the completed new URAR, and Fannie Mae maintains a full resource page on the redesign.
Frequently Asked Questions
Will the new appraisal form change my home's value?
No. UAD 3.6 changes how value is documented, not how it is determined. The same home appraised under the old form and the new form should reach the same value conclusion. Over time, the richer data may produce more consistent valuations, since features like recent renovations are now captured in structured fields every reviewer sees.
Will appraisals take longer or cost more after November 2?
Possibly, in the short term. Appraisers report that their first assignments in the new format take longer while they learn the workflow, and some may adjust fees during the transition. Most projections have turn times and costs normalizing once the industry settles in, and the automation the new data enables should eventually make the process faster than it was before.
What happens if my appraisal was completed before the deadline?
Appraisals submitted to the agencies before November 2, 2026 can use the old format, even if the loan closes afterward. Revisions to those older reports are accepted until May 3, 2027. If your loan is in process this fall, your lender will know which format applies. It requires nothing from you.
Is an appraisal the same thing as a home inspection?
No, and the new form does not change the distinction. The appraisal protects the lender by confirming the home's value supports the loan. A home inspection protects you by evaluating the home's systems and condition in far greater depth. Buyers should not treat even the new, more detailed appraisal as a substitute for an inspection.
Does UAD 3.6 apply to FHA and VA loans?
Not yet on a mandatory basis. The November 2 requirement covers conventional loans sold to Fannie Mae and Freddie Mac. FHA accepts the new format on an optional basis and is expected to set its own deadline, while VA and USDA have not announced timelines. Most borrowers have conventional loans, so most appraisals will be on the new form this fall.
The Bottom Line
The appraisal form that anchored every home purchase and refinance since 2005 retires on November 2, 2026. UAD 3.6 and the redesigned URAR replace a stack of rigid forms with a single dynamic report that captures more about your home, explains itself more clearly, and feeds the most powerful property databases ever assembled. The transition will be bumpy for parts of the appraisal industry, but for buyers, sellers, and homeowners, the destination is a valuation process that is more transparent and better documented than the one it replaces.
The practical takeaway is about timing and preparation. If you are planning a purchase or refinance this fall, build in a little flexibility around the transition window and work with a lender whose process will not bend under industry wide change.
If a move or a refinance is on your horizon, you can check current rates anytime without an application, and our team is glad to walk you through how the new appraisal process fits into your specific timeline.
