Home Appraisals Are Changing in November 2026: What Northern Virginia Sellers Need to Know
If you’re selling a home in Northern Virginia in late 2026 or after, there’s a fairly big change coming to the appraisal process you should be aware of. Starting November 2, 2026, Fannie Mae and Freddie M
ac are moving to a redesigned appraisal reporting system called Uniform Appraisal Dataset 3.6, or UAD 3.6.
That name probably means very little to the average homeowner, and you definitely don't need to learn the technical side of it before putting your house on the market. But the part worth knowing is that appraisers will have a new way of documenting properties, with considerably more structured information about the home and its features.
For sellers, I think there’s a pretty simple takeaway: keep good records of what you’ve done to your house and make that information easy for the appraiser to find.
Key Takeaways
Your home’s value won’t change: Appraisers still go off comps and the market, so the new report is really just more detail, not a new way of figuring out what your house is worth
Start a list of upgrades: Roof, HVAC, kitchen, that kind of thing, with rough years
It kicks in November 2: The new report becomes required for Fannie and Freddie loans, so anything closing around then might run a little slower
What Is Changing With Home Appraisals in November 2026?
For years, residential appraisers have used different appraisal forms based on the type of property they were evaluating. A single-family home might use the familiar 1004 form, for example, and a condo might use a 1073.
Under the new system, those separate forms are being replaced with a single flexible Uniform Residential Appraisal Report, or URAR. The report changes depending on the property and type of appraisal being completed, according to Freddie Mac’s UAD 3.6 guidance.
Freddie Mac describes the new report as one that covers different property types and replaces the existing GSE appraisal forms. Fannie Mae’s UAD information also explains that the new system uses a more structured and data-driven appraisal format.
For homeowners, you don't really need to care what form number your appraiser uses. What matters is that the new report can capture a lot more detail about your property.
What Will Appraisers Be Looking At?
Appraisers have always looked at the condition, features and improvements of a property. The new format gives them a more standardized way to record those details instead of relying as heavily on free-form comments and addenda.
Depending on the property, the appraisal may include more detailed information about things like:
Condition of individual rooms
Kitchen and bathroom updates
Energy-efficient improvements
Solar systems
Smart-home technology
Accessory dwelling units
Secondary living spaces
Site characteristics
Neighborhood influences
Other unusual property features
The new reporting standards also come with expanded photo and data requirements in certain situations. Fannie Mae has published specific UAD 3.6 guidance and supporting documentation covering the information included in the redesigned appraisal process.
That can matter quite a bit in Northern Virginia, where two homes that look almost identical in the tax record can be very different once you walk through the front door. One Arlington rambler may still have its original layout, and the one next door may have a rear addition, renovated kitchen and completely rebuilt lower level.
Does The New Appraisal System Change How Much Your House Is Worth?
No. The new appraisal report does not create a new method for calculating home values. Appraisers will still look at comparable sales, market conditions, the condition of the property, its features and the other factors they already use when developing an opinion of value.
So please don't install a smart thermostat because you read that smart-home features are now documented on the appraisal. Your $200 thermostat is not about to add $10,000 to your appraised value.
The more useful part of the change is that appraisers have a better structure for recording differences between properties. A heavily renovated home and the untouched house down the street may look similar in basic MLS data, but the specific details can tell a very different story.
Start Keeping a Better List of Your Home Improvements
I already ask my sellers for a list of improvements before we put a house on the market. With more detailed appraisal reporting, that list becomes even more useful.
Before your home is appraised, try to gather the approximate dates and basic details of larger projects such as:
Roof replacement
HVAC replacement
Water heater replacement
New windows
Kitchen renovations
Bathroom renovations
Finished basements
Additions
Electrical panel upgrades
Plumbing upgrades
New flooring
Insulation improvements
Solar panels
EV chargers
Energy-efficient upgrades
Smart-home systems
Accessory dwelling units
Drainage or waterproofing work
Structural repairs or improvements
You do not need to hand the appraiser a binder containing every receipt from every trip you've made to Home Depot since 2003. A short, organized list with dates, descriptions and useful documentation for the bigger projects is usually far easier to work with.
If you have permits, invoices or warranties for major work, keep those available too. For a substantial remodel or addition, even old listing photos or before-and-after photos can sometimes help explain exactly what changed.
Your home’s improvements deserve to be seen
I’ll make sure the appraiser knows what you’ve actually done.
Don't Assume the Appraiser Knows What Renovations You've Done
An appraiser sees your property for a relatively short period of time. They weren't there when you replaced your windows, converted the basement, or spent $80,000 rebuilding the kitchen.
Some improvements are obvious. Others are almost impossible to identify during a walkthrough unless someone tells the appraiser about them.
A few examples:
The roof was replaced three years ago
Both HVAC systems are newer
The attic received additional insulation
The electrical panel was upgraded
The basement bathroom was permitted
The windows were replaced throughout the house
The detached building has electricity and insulation
The lower level has a legal bedroom with proper egress
A solar system is owned rather than leased
The home has an EV charging circuit in the garage
Giving an appraiser that information isn't the same thing as trying to tell them what the house should be worth. You're giving them accurate information about the property so they have the full picture when completing the report.
Do Comparable Sales Still Matter?
Yes. Regardless of all the changes to the new appraisal form, comparable sales aren't going anywhere. They remain a major part of how an appraiser analyzes residential value.
This can get interesting in Northern Virginia because a geographically close sale isn't always the most comparable sale. School boundaries, subdivisions, condo associations, lot characteristics and even which side of a major road a property sits on can make a difference.
Before an appraisal, I generally want the appraiser to have useful information about the property and relevant nearby sales. That's particularly helpful if the house has something that isn't common in the neighborhood, such as:
A legal accessory dwelling unit
A large addition
A three-car garage
An unusually large or private lot
A finished walkout basement
Extensive recent renovations
A lot backing to parkland or protected space
An elevator
A separate in-law or multigenerational living area
The appraiser still decides which comparables to use and what adjustments are appropriate. My job isn't to do the appraisal for them, but I also don't see any reason to make good information difficult to find.
Will Appraisals Take Longer?
They might, especially as appraisers, lenders and appraisal management companies get used to the new system. UAD 3.6 requires a different reporting structure, new data requirements and updated appraisal software.
Fannie Mae opened broad production on January 26, 2026, allowing lenders to begin submitting UAD 3.6 appraisal reports months before the mandatory transition. Fannie Mae’s broad production announcement explains that this period was intended to give lenders and other industry participants time to transition before the November deadline.
There could still be some bumps during the transition. If you're buying or selling around November, I wouldn't panic about it, but I also wouldn't assume every appraisal will move through exactly as quickly as it did under the old system.
When Does the New Appraisal Requirement Start?
The main date homeowners need to know is November 2, 2026. Fannie Mae says new appraisal reports submitted after the mandate generally need to use UAD 3.6, with additional details available in its UCDP transition guidance.
There is a temporary exception process for lenders that aren't ready by the deadline. Freddie Mac's current UCDP FAQ says a lender that cannot meet the mandate may request a policy exception allowing continued UAD 2.6 submissions during an approved exception period.
The basic timeline looks like this:
January 26 through November 1, 2026: Lenders can use either UAD 2.6 or UAD 3.6.
November 2, 2026: UAD 3.6 becomes mandatory for new appraisal submissions, subject to approved temporary exceptions.
May 3, 2027: The legacy UAD 2.6 system is scheduled to retire, including revisions to previously submitted legacy reports.
Fannie Mae and Freddie Mac have continued updating their guidance as the deadline gets closer, so transactions right around the transition may not all look identical. The underlying November 2 mandate remains in place, and Fannie Mae’s implementation timeline has more detail for anyone who wants the technical version.
What Should a Seller Do Before an Appraisal?
You don't need to do anything drastic just because the appraisal form changed. A little organization before the appraiser arrives can help make sure useful property information doesn't get missed.
Here's what I'd suggest to my clients:
Make an improvement list. Include the project and approximate year it was completed.
Find documentation for major work. Permits, invoices and warranties are useful when you have them.
Tell your agent about the boring upgrades too. A new sewer line or electrical panel may not photograph as well as a new kitchen, but we still want to know about it.
Include less obvious features. Energy improvements, smart-home systems, EV chargers and secondary living spaces are worth documenting.
Make the whole property accessible. Attics, basements, garages, mechanical rooms and other relevant spaces shouldn't be blocked or locked.
Keep the information concise. A clean one- or two-page improvement sheet is usually better than dropping a stack of paperwork on the appraiser.
Let the appraiser do their job. Give them useful facts and then give them room to inspect the house.
The last one deserves mentioning because sellers understandably get nervous about appraisals. Following the appraiser from room to room explaining why every improvement should add a specific dollar amount usually isn't helping anybody.
Could the New System Help Heavily Updated Homes?
Possibly, although I wouldn't advertise UAD 3.6 as some sort of appraisal jackpot for renovated houses. The report provides a better structure for documenting property characteristics, but buyers and comparable sales still have a lot to say about what those improvements are actually worth.
Think about two Fairfax homes that both show up in the basic property data as 4 bedrooms, 3 bathrooms, ~2,400 square feet, and built in 1972. One still has its original bathrooms, older windows, aging mechanical systems and a kitchen remodeled sometime around the invention of AOL. The other has a renovated kitchen, updated bathrooms, replacement windows, newer roof, newer HVAC and a professionally finished basement.
Those homes clearly aren't identical. More detailed reporting gives the appraiser another way to document those differences instead of having so much of that information buried in narrative comments.
Selling a Northern Virginia Home in 2027?
If you're planning to sell in Arlington, Alexandria, Fairfax, Prince William or Loudoun County, I wouldn't change your entire selling plan because a new appraisal system is coming. I would spend an hour getting your home improvement information together, though, because that's useful before the appraisal even enters the picture.
It helps me understand how to position the property, gives buyers better information and gives us something organized to provide when the home is eventually appraised. And if you're trying to decide which repairs or updates are actually worth doing before you sell, that's something we can figure out before you start writing checks to contractors.
Sometimes the expensive project you've been assuming you need isn't the one I'd recommend at all. There are plenty of improvements that sound good in theory but don't make enough difference at resale to justify the cost.
