A major change to residential real estate appraisals is taking effect this fall. Beginning November 2, 2026, Fannie Mae and Freddie Mac will require new appraisal reports submitted to their systems to use the updated Uniform Appraisal Dataset (UAD 3.6).
While this is primarily a change to how appraisals are documented and reported, it could affect the appraisal process for buyers and sellers throughout Massachusetts.
What Is UAD 3.6?
UAD 3.6 replaces the older appraisal reporting system with a more standardized, data-driven format. Instead of relying on multiple traditional appraisal forms, the new system uses a flexible report designed to accommodate different residential property types.
The goal is to improve consistency, capture more detailed property information and make appraisal reports easier to review.
What Are the Main Changes?
1. A redesigned appraisal report
The traditional appraisal forms are being replaced by a single, flexible report that adapts to the property being evaluated, including single-family homes, condominiums and smaller multifamily properties.
2. More detailed property information
The updated format standardizes how appraisers document property characteristics, condition, quality, measurements and other details. This includes more specific reporting requirements for square footage.
3. Greater consistency
By collecting information in a more structured format, the new system is intended to improve the consistency and quality of appraisal data across different properties and markets.
What Does This Mean for Massachusetts Buyers and Sellers?
For most buyers and sellers, the underlying purpose of an appraisal remains the same: to provide an independent opinion of a property’s market value.
However, the transition may affect documentation requirements and workflows for lenders and appraisers. As the industry adapts, some transactions could experience additional coordination or processing delays.
Sellers should continue to focus on accurate pricing, property presentation and providing relevant information about improvements and comparable sales. Buyers should understand that the new reporting format does not guarantee that a home will appraise at its purchase price.
Importantly, UAD 3.6 does not automatically increase or decrease property values. The appraisal still depends on the property’s characteristics, market conditions and supporting comparable sales.
When Do the Changes Take Effect?
Fannie Mae and Freddie Mac have established November 2, 2026, as the mandatory transition date for new appraisal reports submitted to their systems. The rollout began earlier in 2025, with broader production access opening in January 2026.
The requirement applies to covered conventional loans delivered to these agencies, not automatically to every mortgage program.
