Colorado Appraisals Just Changed. Here's What Sellers and Buyers Need to Know.

The way homes are appraised in Colorado is changing, and most people sitting across the table from you at closing have no idea it's happening. If you're buying or selling with a conventional loan, this affects your transaction right now. The new appraisal report, called UAD 3.6, becomes mandatory for all loans sold to Fannie Mae or Freddie Mac on November 2, 2026.

Here's what it means in plain terms, and what you can actually do about it.

What Changed With Colorado Appraisals

Fannie Mae and Freddie Mac rolled out a redesigned appraisal format called UAD 3.6. It replaces the old standard forms most people in real estate have worked with for years, including the familiar 1004, 1073, and 2055. Those forms are gone. One dynamic report replaces all of them.

The new format collects significantly more data. Appraisers now document condition and updates room by room, not just as a summary for the whole property. Every improvement gets logged with dates and details. The report is more thorough, more transparent, and more time-consuming to complete.

That means appraisals take longer and cost more. It also means more defects get called out, because there are more fields to fill in and more of the property to document.

Which Loans Does the New Appraisal Apply To

UAD 3.6 applies to conventional loans sold to Fannie Mae and Freddie Mac. That is the bulk of residential transactions.

FHA and VA are a different story. FHA has announced it will eventually transition to UAD 3.6, but has not set any dates. VA has no firm timeline either. For now, FHA and VA loans continue to use the old standard report.

This matters in a real way. If a buyer starts with an FHA or VA loan and switches to conventional during the transaction, they will need a brand new appraisal. The old report does not transfer over. Factor in that cost and time early if a loan type switch is on the table.

What Sellers Think Adds Value (But Doesn't)

This comes up in almost every listing conversation, and the new appraisal form makes it more important to understand.

If there is no comparable sale data to support an improvement, an appraiser cannot give it value. It does not matter how much the seller spent on it. Egress windows are a good example. Installing egress in a basement does not automatically create an appraised bedroom. Appraisers need a comp of another home in the area with the same configuration that sold at a higher price because of it. If that data does not exist, the value does not exist.

The same logic applies to any unique upgrade. If you are the only home in the neighborhood with a particular feature, it will be very difficult to get credit for it. The market has to reflect it somewhere for an appraiser to support it numerically.

How to Help the Appraiser

There are things you can do as a seller or listing agent to make the appraisal go more smoothly under the new form.

Prepare a written list of all updates to the property with dates and details. The new report requires this information anyway. Hand it to the appraiser upfront and they have what they need without having to guess or leave things undocumented.

Order the appraisal earlier than you normally would. UAD 3.6 takes more time to complete. Building that in on the front end prevents it from becoming a closing delay.

Meeting the appraiser at the property is worth considering. Not every appraiser welcomes it, so read the situation. But being available to walk through updates, point out recent improvements, or clarify anything that is not obvious from a visual inspection can make a real difference in what gets documented.

Where This Is All Heading

The reason Fannie Mae and Freddie Mac are collecting this much additional data is to feed it into automated valuation models. More structured data means those systems get smarter about property values over time.

The likely long-term result is more appraisal waivers. As the AI models improve, more transactions will qualify to skip the traditional appraisal entirely because the system has enough data to make the call confidently. We are not fully there yet, but UAD 3.6 is a direct step in that direction.

Frequently Asked Questions

What is the UAD 3.6 appraisal form?
UAD 3.6 is the redesigned appraisal report now required by Fannie Mae and Freddie Mac for conventional loans. It replaces older forms like the 1004 and collects more detailed data about a property's condition and updates on a room-by-room basis.

When does the new appraisal form become mandatory?
November 2, 2026 is the mandatory date for all loans sold to Fannie Mae or Freddie Mac. Both the old and new formats have been accepted during a transition period, but the old forms will no longer be accepted after that date.

Does UAD 3.6 apply to FHA and VA loans?
Not yet. FHA has announced it will eventually adopt UAD 3.6 but has not set a date. VA has no firm timeline announced. Both continue to use the old standard appraisal report for now. If a buyer switches from FHA or VA to a conventional loan mid-transaction, a new appraisal will be required.

Why does the new appraisal report call out more defects?
UAD 3.6 requires condition ratings room by room and more detailed documentation throughout the property. More fields means more of the home gets assessed and reported on, which surfaces defects that a less detailed form might not have flagged.

How can a seller prepare for the new appraisal process?
Prepare a written list of all updates with dates and details before the appraiser visits. Order the appraisal earlier than usual to account for the additional time required. Being available to meet the appraiser at the property can also help ensure improvements are properly documented.

Do unique home improvements add value in an appraisal?
Only if there is comparable sales data to support them. If you are the only home in the area with a specific feature, an appraiser will have difficulty assigning value to it regardless of cost. Appraisers work from comparable sales, so improvements without market data behind them are hard to credit.
