If you're buying or selling a home in 2026, there's an important change happening in the way residential real estate appraisals are completed and reported.
Fannie Mae and Freddie Mac are introducing a new appraisal reporting system called UAD 3.6 (Uniform Appraisal Dataset). This is one of the biggest changes to residential appraisal reporting in approximately 25 years.
Here's what you need to know and how it could affect your real estate transaction.
For years, appraisers have used standardized appraisal forms to evaluate residential properties. The new UAD 3.6 system replaces those traditional forms with a more detailed, data-driven reporting format.
The new system is designed to collect more consistent and detailed information about a property, including:
Individual rooms and living areas.
Property condition and quality.
Improvements and renovations.
Exterior features and amenities.
Property characteristics and layout.
Photographs and supporting documentation.
The goal is to create more comprehensive and consistent appraisal reports.
It could.
Because the new reporting system requires more detailed property information, appraisers may need additional time to inspect, document and report on a home.
During the transition, appraisers, lenders and appraisal management companies are also adapting to new technology and procedures.
What this means for buyers and sellers: Allow reasonable time for the appraisal process, and communicate with your lender about anticipated appraisal and closing timelines.
A little preparation can make the appraisal process easier.
Before the appraiser visits, consider putting together a list of information about your property, including:
Recent renovations and upgrades.
Approximate dates of major improvements.
New roofing, windows, HVAC systems or appliances.
Kitchen and bathroom remodeling.
Finished basement or additional living space.
Special features or amenities.
Permits or documentation for significant improvements, when available.
Keep receipts, contractor information and other documentation if you have them.
Remember, improvements do not automatically increase a home's appraised value dollar for dollar. The appraiser must consider the property's overall condition, market conditions and comparable sales.
Buyers should understand that the appraisal remains an important part of the mortgage lending process.
The appraisal helps the lender evaluate whether the property provides sufficient collateral for the requested loan.
A few things to remember:
The appraisal is not the same as a home inspection.
The appraised value may be different from the agreed-upon purchase price.
A low appraisal could require additional discussions between the buyer, seller and lender.
Buyers should ask their lender about appraisal timing early in the transaction.
November 2, 2026, was the important implementation date for Fannie Mae and Freddie Mac.
However, there is an important update: Eligible lenders that receive a temporary policy exception may continue submitting appraisals using the previous reporting format through May 19, 2027.
This means buyers and sellers may encounter both the traditional appraisal format and the new UAD 3.6 format during the transition.
The November 2 requirement applies to applicable conventional loans involving Fannie Mae and Freddie Mac. FHA, VA and USDA loans have separate appraisal requirements and implementation schedules.
Your lender determines which appraisal format applies to your transaction.
The reporting process is changing, but the fundamental purpose of an appraisal has not changed.
An appraiser still provides an independent, objective opinion of a property's market value based on relevant market data, comparable sales, property characteristics and professional analysis.
The new system provides a more detailed way to collect and communicate that information.
The 2026 appraisal changes are designed to modernize residential appraisal reporting and provide more detailed property information.
For buyers and sellers, the best approach is to:
Stay in communication with your real estate professional and lender.
Allow adequate time for the appraisal process.
Keep records of renovations and property improvements.
Be prepared to answer questions about your home's features and condition.
Understand that the appraisal is an independent evaluation, not a guarantee of the purchase price.
Knowledge and preparation can help make your real estate transaction a smoother experience.
