New Appraisal Rules Are Here: What Phoenix Area Homeowners Need to Know About UAD 3.6

If you’re buying, selling, or refinancing a home in the Phoenix metro area, there’s a major change in the appraisal process that you should know about. In my 30+ years in this market, I’ve seen plenty of shifts, but this is the biggest overhaul to appraisal reporting in well over a decade.

Here’s what changed, what it means for you, and how to prepare.

What Changed?

Starting November 2, 2026, every new appraisal report submitted for a conventional loan sold to Fannie Mae or Freddie Mac must use a new format called UAD 3.6 (Uniform Appraisal Dataset 3.6). That change is already in effect.

In plain English, the old fixed-format appraisal forms are being replaced with a redesigned, more dynamic report. The new Uniform Residential Appraisal Report adapts to the type of property and the purpose of the appraisal, and it collects more structured data about the home and the market than the old forms did.

What Did Not Change

This part is important: how a home is valued has not changed. Your appraiser still researches comparable sales, evaluates your home’s condition and features, and uses professional judgment to reach an opinion of value. The new format changes how that information is reported, ordered, and delivered. It doesn’t replace the appraiser’s expertise.

A Quick Note on the Timeline

Fannie Mae and Freddie Mac announced a temporary exception on September 30 for lenders that couldn’t finish their UAD 3.6 setup in time. That means some lenders may still be accepting the older format for a limited period, but the transition is moving in one direction. Reports submitted in the old format under an exception will face reduced functionality starting March 1, 2027, and the legacy format is scheduled to be retired for good in mid-2027. FHA has also announced its move to the new format.

So the practical takeaway is that different lenders may be on different timelines right now. It’s worth asking yours which format they’re using.

What Homeowners Should Consider

1. Document your upgrades. The new report is built to capture more detailed property information. Keep a simple file with receipts, dates, and descriptions for improvements such as a new roof, HVAC replacement, remodeled kitchen or baths, flooring, windows, pool updates, and solar. Giving your appraiser clear, organized information helps them accurately reflect your home’s features.
2. Understand that features don’t equal automatic value. The new framework pays closer attention to things like energy-efficient and resilience features. But the presence of a feature does not mean a dollar-for-dollar increase in value. The appraiser still needs market evidence, meaning comparable sales, to support any value difference.
3. Condition and quality matter. Updated condition and quality rating standards are part of the new approach. This is one more reason to stay on top of maintenance and avoid deferred repairs, especially the Arizona essentials like roof, stucco, HVAC, and pool equipment.
4. Ask your lender and agent about timing. Since lenders are transitioning at different speeds, ask early which appraisal format will be used and how long the appraisal is expected to take. An appraisal ordered before November 2 doesn’t automatically qualify to be submitted in the older format afterward.
5. Be prepared for possible cost and timing changes. Industry reports suggest the transition may affect appraisal costs and turnaround times in some cases as appraisers and lenders adjust to the new system. Ask your lender about fees up front so there are no surprises, and build a little extra time into your closing schedule.
6. Prepare your home for the appraisal visit. Make sure the appraiser has easy access to the whole property, including the garage, attic access, and backyard. Clean and tidy the home, fix small items like leaky faucets or burned-out lights, and have your list of upgrades ready.
7. Work with a local agent who knows your neighborhood. Appraisals depend on good comparable sales. A local agent can pull the most relevant, recent comps for your area, whether you’re in Gilbert, Chandler, Mesa, Scottsdale, or Queen Creek, and can provide helpful market context to share with the appraiser.

What If the Appraisal Comes in Lower Than Expected?

A low appraisal can happen under any format. If it does, here are your options:

• Ask your lender about requesting a reconsideration of value, and provide additional comparable sales or corrections if you believe something was missed.
• Negotiate with the other party. Buyers and sellers can often renegotiate the price, split the difference, or adjust terms.
• Pay the difference in cash if you’re a buyer and the numbers still make sense.
• Review your options with your agent before making any decisions.

My Advice

Don’t let the new format intimidate you. The fundamentals of a good appraisal are the same: a well-maintained home, good documentation, and strong local market knowledge. Staying organized and starting conversations with your lender and agent early will go a long way.
