Home Appraisal Changes in 2026: What Denver Sellers and Buyers Need to Know

If you are preparing to sell or buy a home in the Denver area, you may have heard that home appraisals are changing. The biggest upcoming shift is a redesigned appraisal report called UAD 3.6, developed by Fannie Mae and Freddie Mac.

For consumers, the practical takeaway is straightforward: expect more structured information about the property, clearer documentation of its condition, and a different-looking report. The change does not automatically increase or decrease a home’s value.

For sellers, my recommendation is to prepare early and document improvements. For buyers, it is to understand the appraisal process, review the report, and discuss potential issues with your lender before closing.

What is changing, and when?

UAD stands for Uniform Appraisal Dataset. The new system replaces a collection of older appraisal forms with a flexible Uniform Residential Appraisal Report that adapts to the property and appraisal assignment. Its purpose is to make property information more consistent and easier to review.^[1]

November 2, 2026 remains the stated mandate for new appraisal submissions to Fannie Mae and Freddie Mac’s appraisal portal. However, there is an important transition exception.

On September 30, 2026, the agencies announced that lenders needing additional time can request an exception allowing continued use of the older format through May 19, 2027.^[2] That means buyers and sellers may encounter different report formats during the transition.

This is a change to appraisal reporting for loans sold to Fannie Mae and Freddie Mac. It should not be described as a new Colorado law or a universal deadline for every FHA, VA, jumbo, portfolio, or privately ordered appraisal. Ask your lender which requirements apply to your loan.

What will the new appraisal report look at?

Interior and exterior condition receive separate attention

The new framework includes overall, interior, and exterior condition and quality ratings.^[3]

Condition describes the property’s state of maintenance and repair. Quality describes its construction, materials, and workmanship. A well-maintained home can have standard finishes, while a home with expensive finishes can still need repairs.

For example, a Denver bungalow might have a recently remodeled kitchen but older exterior components. The report has a clearer way to describe those differences. A kitchen remodel does not make the entire home newly renovated.

Expect detailed photo documentation

The new reporting guidance specifies required and conditional photos for applicable sections, including kitchens, bathrooms, main living areas, bedrooms, below-grade spaces, and certain additional structures or features.^[4]

For a seller whose appraisal includes an interior visit, the practical preparation is to make the whole property accessible. A room used for storage or an unfinished basement may still need to be documented.

Square-footage terminology may look different

You may see terms such as “above-grade” and “below-grade” finished area. But separating basement space from above-grade living space is not a new November 2026 rule. Fannie Mae’s ANSI measurement requirement for applicable appraisals dates to April 2022, and it announced terminology updates in 2025.^[5]

A finished basement can contribute value even though it is reported separately.

A house with 1,500 square feet above grade and 1,000 finished square feet below grade should not automatically be treated as equivalent to a house with 2,500 square feet entirely above grade. That distinction matters when comparing homes with finished basements, split-level layouts, and additions.

My recommendations for Denver home sellers

1. Create a simple improvement record

Before listing, gather a concise list of improvements with completion dates and supporting records where available:

Roof, window, heating, cooling, and water-heater replacements.
Kitchen and bathroom renovations.
Electrical, plumbing, sewer, or structural work.
Additions, basement finishes, and associated permits or final approvals.
Solar ownership or lease documents and information about energy improvements.

Be specific. “Roof replaced in 2023” is more useful than “everything updated.” Identify partial renovations accurately.

These records help explain the property. They do not guarantee a dollar-for-dollar increase in appraised value.

2. Prioritize repairs that affect function and condition

My advice is to review unresolved maintenance before spending heavily on cosmetic upgrades. Leaks, damaged materials, unfinished work, and malfunctioning components deserve attention.

The right preparation plan depends on your budget, timeline, and likely buyer. The new report alone is not a reason to replace a functional kitchen or undertake a major renovation.

A dated home and a poorly maintained home are different things. Your preparation and pricing should reflect the actual property.

3. Check square-footage and property descriptions early

If public records, an old listing, and a floor plan disagree, investigate before the appraisal.

Pay particular attention to additions, converted garages, finished attics, basement bedrooms, and accessory living spaces. Gather the available documentation and make sure marketing descriptions distinguish the different areas accurately.

4. Prepare for access and photographs

Clear paths through rooms and around mechanical equipment. Coordinate access to garages, outbuildings, and other relevant spaces. Secure pets and put away sensitive personal paperwork before the appointment.

A tidy home makes observation easier, but staging and cleanliness do not substitute for sound condition.

5. Support the price with evidence

Your agent can provide relevant comparable sales, an accurate improvement list, and factual information about the property. The appraiser must reach an independent opinion of value.^[6]

For my sellers, appraisal preparation belongs in the conversation about pricing and home preparation from the beginning.

What Denver buyers should know

Ask your lender about timing and cost

If your purchase falls during the transition, ask:

Which appraisal format and valuation process will my loan use?
What fee and turnaround time should I expect?
How will we handle additional documentation or repair requirements?

The published transition does not establish one universal consumer fee increase or delay. Get an estimate for your specific property and loan.

Keep your home inspection

A more detailed appraisal still serves a different purpose from a home inspection. It supports the lender’s valuation decision; it does not replace your investigation of the home’s systems and condition.^[7]

Read the report beyond the value

Review the property description, reported size, condition, improvements, and comparable sales. If something appears inaccurate, raise it promptly with your lender.

Borrowers can request a reconsideration of value through the lender when an appraisal may contain errors or omit relevant information. Provide specific evidence. A reconsideration does not guarantee a different value.^[7]

Discuss a low appraisal before making an offer

The redesigned report does not eliminate appraisal gaps. If the appraised value falls below the contract price, discuss the financing impact with your lender and the contractual options with your agent.

Depending on your loan and contract, the response might involve negotiating the price, contributing additional cash, requesting review of an error, or exercising an applicable contract right. Do not assume the seller must reduce the price or that you can cancel without consequences.^[8]

Preparing for your next move

The appraisal changes make accurate property information and thoughtful preparation especially useful. Sellers can prepare by documenting improvements, addressing maintenance, and supporting their price with comparable sales. Buyers can prepare by understanding their financing, reviewing the report, and protecting time for due diligence.
