If you're planning to buy, sell, or refinance in the coming months, there's a change happening behind the scenes of your transaction that's worth understanding now, before it affects your closing timeline. Starting November 2, 2026, every appraisal sold to Fannie Mae or Freddie Mac must be completed on a new standardized format called UAD 3.6 — and it's the biggest overhaul to how homes get appraised in decades.
What's Actually Changing
For as long as most of us have been in this business, mortgage appraisals have followed a rigid, form-based structure — essentially a template built for a different era of paperwork. UAD 3.6 replaces that with a dynamic, data-driven report that expands or contracts based on the actual characteristics of the property and the type of inspection performed, rather than forcing every home into the same fixed template.
In practice, that means:
- A standardized front page across all appraisal report types, regardless of property type
- More granular data fields, including new energy-efficiency metrics
- Faster, more consistent automated review by lenders, since the data arrives in a structured digital format instead of narrative text
Lenders have already been phasing this in since late 2025, with broad availability since January 2026. The November 2 deadline is simply when the old forms stop being accepted for GSE-backed loans altogether.
Why This Matters to You, Not Just Appraisers and Lenders
It's easy to assume this is purely a back-office change. It isn't — here's where it touches your transaction directly:
Appraisers may need more from you or your agent. With expanded data fields to fill in, appraisers are expected to reach out to listing agents more frequently than in the past to confirm property details. If you're selling, expect your agent to field a few more of these calls — and make sure your listing details are accurate and complete going in, since that's the information appraisers will be cross-checking.
There may be a short adjustment period. Any time an industry-wide reporting standard changes, there's a learning curve. Some early reporting suggests appraisal turnaround times could stretch slightly as appraisers, lenders, and AMCs (appraisal management companies) get comfortable with the new format. If you're on a tight closing timeline this fall or into early 2027, it's worth building in a small buffer.
The broker's role stays the same — with an important boundary. You or your agent can absolutely provide documentation and information to help an appraiser do their job accurately — comps, upgrades, permits, whatever's relevant. What hasn't changed, and won't change under the new standard, is that agents and brokers still cannot attempt to influence an appraiser's opinion of value. That line matters more, not less, as data becomes more central to how these reports are built.
Energy-efficiency data is now part of the picture. For South Florida properties, particularly newer builds or homes with recent hurricane-hardening, impact windows, or solar upgrades, this is worth watching. As appraisal reports begin capturing more granular efficiency and resiliency data, well-documented upgrades may become easier to reflect in valuations going forward.
What We're Watching Between Now and November
This transition is still unfolding, and the real-world impact — on turnaround times, on how comps get pulled, on how upgrades get valued — will become clearer as more lenders complete the switch. A few things on our radar for South Florida specifically:
- Whether appraisal timelines in our market shift meaningfully during the transition window
- How hurricane-related upgrades (impact windows, roof age, elevation certificates) get captured in the new format
- Whether the added data granularity changes how quickly appraisals come in relative to contract price in a market like ours, where comps can vary block to block
The Bottom Line
If you're under contract or planning to list before or around November 2026, this isn't something to worry about — it's something to be aware of. The fundamentals of a strong appraisal outcome haven't changed: accurate listing data, well-documented upgrades, and solid comps still carry the day. What's changing is the format those things get reported in, and a modest transition period while the industry adjusts.
