A Practical Guide to Appraising Accessory Dwelling Units (ADUs)

By Freddie Mac

Excerpts: Sample Topics:

Appraisal Considerations:

Firstly, an appraiser can’t simply ignore an ADU. If the determination is made that additional finished area qualifies and meets the definition of an ADU, there are some practical steps the appraiser must take in the analysis.

Appraisal Development:

The appraiser will need to determine any effect the ADU has on the market value or marketability of the subject property. The appraiser’s analysis must be documented in the appraisal report and conclude whether an adjustment is supported for the ADU (remembering that the conclusion for no adjustment also requires market support).

Allowable Flexibility:

A good best practice for any appraiser is to reference and use Freddie Mac resources and published appraisal guidelines, which detail the steps an appraiser may take when valuing a property with an ADU. If a subject property ADU complies with zoning and land use requirements, the appraisal report must include at least one comparable sale with an ADU. If not available, then the appraiser may consider an older sale from the subject’s market or a competing market. The appraiser may also expand the search and comparison beyond just three sales, including pending contract sales or listings to justify the support for adjustments.

How to Defend Adjustments in Appraisal Reports

When someone questions an adjustment, many appraisers respond, “It’s based on market data” or “my experience in the market.” These statements might be true, but they don’t support the adjustment. They just state where it came from.

Appraisal reports are similar to scientific papers. A scientist can’t write “Based on my experiments, the hypothesis is correct” and expect peer review to accept it. Scientists need to share their methodology, summarize their analysis, and support their conclusions.

The same applies to appraisal adjustments. Saying you used market data is like saying you conducted an experiment. It’s just the starting point. Your report needs to summarize how you analyzed the data and how it supports that specific adjustment.

Without this documentation, you haven’t provided credible analysis. You’ve stated an unsupported opinion, regardless of your experience.

You need a clear path from market evidence to the number on your grid. Defending appraisal adjustments isn’t one perfect technique. It’s about using multiple, credible methods, explaining your logic, and sequencing your work so it aligns with how the market behaves and with USPAP.

Below is a practical, step-by-step approach you can put to work right away.

Start with the Right Sequence

Before you calculate any adjustment, get the order right. In practice, you should follow this sequence:

  • Apply transactional adjustments:
  • Real property rights conveyed
  • Financing terms
  • Conditions of sale
  • Expenditures made after purchase
  • Market conditions (time)
  • Apply property adjustments:
  • Location
  • Physical characteristics (e.g., finished square footage, bathrooms, garages, condition, quality)

Transactional adjustments affect the overall transaction price, and each adjustment creates a new base for the next one. They answer the question, “What would this comparable have sold for under typical terms on my effective date?”

These adjustments normalize the sales by removing distortions from unusual financing, non-market conditions, or time differences.

Equalize Market Conditions Before You Compare

Nobody is Ready for UAD 3.6

by Isaac Peck, Publisher WorkingRE

I just got back from Valuation Expo, the nation’s largest and most dynamic conference for real estate appraisers and valuation industry stakeholders. More than 800 people made it to Las Vegas this year.

Appraisers, chief appraisers at appraisal management companies (AMCs), lenders, regulators, software developers, service providers, insurance professionals and more convened to talk about the latest technology and explore where the profession is headed.

The mood was elevated and positive—many attendees were genuinely invigorated and excited about the future. And yet, despite all the positivity, another reality was plainly clear from the conversations: Nobody is ready for UAD 3.6.

While many of the leading software providers received initial approval from Fannie Mae and Freddie Mac (the GSEs) in late 2025 and early 2026, word on the ground is that there are still plenty of bugs to work out.

AMC executives privately shared that they have staff simultaneously testing all the GSE-approved appraisal reporting software so they can troubleshoot and support appraisers when they inevitably run into bugs and errors trying to turn in an assignment. Some of those bugs are being run back to the software companies in real time, as appraisers, AMCs, lenders and software providers work together to find a solution.

In other words, while the GSEs tested the main appraisal report software providers on several different types of assignments, there are so many nuances, data fields and report settings that bugs are surfacing rapidly now that appraisers are finally doing live assignments.

In addition to the software challenges, part of the problem is that most lenders haven’t begun ordering UAD 3.6 reports at all.

I spoke with several regional AMCs. Each had completed just two UAD 3.6 assignments—and in each case, one of the two was a test run the AMC had ordered itself.

If one of the largest mortgage lenders in the country has only done six UAD assignments, how many appraisers have actually completed a UAD 3.6 assignment? The answer is very, very few.

An appraisal software executive shared with me privately that he fears appraisers may be (wrongly) blamed if the rollout goes poorly and the market is disrupted. It would be easy to sell a narrative that “appraisers weren’t ready,” or that appraisers can’t handle the new report format. Such a view clearly misses the point. After all, appraisers don’t control the development of the software, nor do they control when UAD 3.6 reports start getting ordered, to Reuter’s point.

Will we see an avalanche of UAD 3.6 orders in September and October, and will the transition happen smoothly by mid-October? It seems unlikely.

Many thanks to Isaac Peck for “in person” realistic reporting on the Most Popular Topic in appraising – Future of UAD 3.6 and GSEs.

Second AQB Exposure Draft Proposals Could Be Game-Changing

By Bryan Reynolds

Comments are due by August 30, 2026. To Post Your Comments, Click Here

The AQB is proposing changes to the appraiser qualification requirements that would significantly change some of the barriers to entry. Here are some highlights. Excerpts: n June 22, 2026, the Appraisal Foundation’s Appraiser Qualifications Board (AQB) released their “Second Exposure Draft of Proposed Changes to the Real Property Appraiser Qualification Criteria.” (Read it here.)

That’s a mouthful. Let me translate: The AQB is proposing some big sweeping changes to the minimum requirements for becoming a real property appraiser. I’m not taking a position on these proposals, but there’s no question that several of them could remove or reduce long-standing barriers to entry for aspiring appraisers.

As AQB chair Jerry Yurek explained: “The proposals do not lower the bar the appraiser credential signifies. They do, however, streamline the path to entry into the profession by eliminating requirements that do not contribute to an applicant’s readiness.”What the Exposure Draft Would Change:

1. Eliminate the College Degree Requirement for Certified Residential and Certified General

2. Remove the Minimum Calendar-Time Requirements for Experience

3. Add a Demonstration Appraisal Report Pathway for Licensed Residential

4. Recognize Experience Already Earned When Moving to a Higher Classification

Make Your Voice Heard

The AQB exposure process is the profession’s opportunity to support, oppose, or recommend revisions to the proposals. Comments are due by August 30, 2026. Whether you are an appraiser, trainee, educator, regulator, lender, or user of appraisal services, review the draft carefully and provide specific, constructive feedback to the AQB.

These proposals could be game-changing. The profession should help determine exactly how the game changes.

For more information from the AQB, Click Here 

My comments: This article is very positive about the reason for the changes and mostly was what the ASB said. Many thanks to Bryan Reynolds for writing up what is proposed.

No college degree for certified general is not a good idea.

I learned how to write long “papers”, open to ideas about new things in college. Of course business classes are good. I never had business classes until I got my MBA 10 years after I started appraising. I became a much better appraiser. Maybe some business classes could be required. Especially financial.

Commercial appraisers need very good math and financial expertise.

The big problem, exposed after licensing, was the experience requirement. People sent out mass mailings to find a mentor. They had no way to determine if they were ethical, knew how to appraise, and more. Of course, fee appraisers have had no teacher training. I still hear stories about trainees who found out their mentor was teaching them the wrong things.

Before licensing, most trainees started at lenders, who had supervisors to train them. I was trained at an assessor’s office with the same set up.I am a musician and learned to play many instruments over the years. I learned to take lessons when I first started playing. Why? So I did not have to un-learn the wrong way to play better. The same applies to appraiser trainees.

============================

A FINAL PLEA — TAKE A FEW MINUTES TO COMMENT BY DOUG SMITH

The AQB has extended the comment deadline on its proposed changes to the Real Property Appraiser Qualification Criteria from July 27 to August 30. With appraisers also trying to prepare for the enormous change represented by UAD 3.6, that extra time is welcome.

But August 30 is now only days away.One proposal deserves particular attention: eliminating the college degree requirement for Certified General appraisers.Whatever your position, this is a major change in the qualifications for entry into our profession. The AQB needs to hear from the people who actually practice appraisal.You do not need to write an essay. Even a short comment stating whether you support or oppose eliminating the college degree requirement — and briefly why — puts an appraiser’s voice into the record.Take a few minutes.

The 3 Basic Requirements for Real Property Appraisal Reports (Updated for UAD 3.6) By Kevin Hecht, SRA

Excerpts: As a real property appraiser, you rely on appraisal reports to communicate your opinion of value. One of the most important principles in USPAP is also one of the most misunderstood: forms are not reports.

Filling out a form properly and completely does not automatically mean your report is USPAP-compliant. The content of the appraisal report, not its form or format, determines compliance.

That distinction has never mattered more than it does right now.

The static forms appraisers have relied on for decades, including the 1004, 1073, 1025, and 2055, are being retired and replaced by a single, dynamic, data-driven reporting structure.

This shift does not change the three foundational requirements of USPAP Standards Rule 2-1. But it does change how you meet them. Understanding that distinction is critical to your compliance and your credibility in the new reporting environment.

TOPICS

What Are the Three Basic Requirements for an Appraisal Report?

Standards Rule 2-1(a): Clearly, Accurately, and Not Misleading

SR 2-1(a) builds on the ETHICS RULE requirement that your appraisal reports must not be misleading. You satisfy this requirement by making sure you “clearly and accurately set forth the appraisal.”

As the saying goes, you must tell the truth, the whole truth, and nothing but the truth.

Under the legacy form-based system, appraisers added context and explanation through a free-form General Addendum, which provided flexibility when a standard data field did not fully capture the nuances of a particular property or assignment.

Under UAD 3.6, that flexibility is now built directly into the report structure itself through section-specific commentary fields, which keeps all relevant analysis organized and immediately accessible to reviewers.

Standards Rule 2-1(b): Sufficient Information for Intended Users

What changes under UAD 3.6 is where and how you provide that sufficient information

Standards Rule 2-1(c): Disclosing Assumptions, Extraordinary Assumptions, Hypothetical Conditions, and Limiting Conditions

Former Florida Resident Sentenced to 20 Years in Federal Prison for Appraisal Fraud

Excerpts from DOJ Press Release

Tampa, FL – Armando Martinez (51, Plano, TX) has been sentenced by Chief U.S. District Judge Amos Mazzant, III, of the United States District Court for the Eastern District of Texas to 20 years in federal prison for bank fraud. Martinez previously pleaded guilty. U.S. Attorney Gregory W. Kehoe made the announcement.

According to court documents filed with the United States District Court for the Middle District of Florida, Martinez, who had his Florida Appraiser’s license revoked, orchestrated and executed a bank fraud scheme directed at multiple financial institutions by taking over the identity and license number of a legitimate licensed appraiser.

Martinez then purportedly conducted onsite appraisals for dozens of properties in Florida. In reality, Martinez paid others to go to the properties and take pictures for appraisals he completed. He then sent the appraisals to the victim lenders, using his computer after having fled the United States to the Dominican Republic.

Based on the false and fraudulent appraisals, the financial institutions were fraudulently induced to approve and fund mortgage loans and pay Martinez appraisal fees. As a result of Martinez’s appraisal fraud, more than $65 million in mortgages are impaired or defective. These mortgages were either guaranteed by the Federal Housing Administration or purchased and guaranteed by Fannie Mae and Freddie Mac.

Dave Towne Comments: Another ethically twisted former appraiser is going to be experiencing “three hots and a cot” for the next 20 years, assuming the full sentence is served.

It never ceases to amaze me how some very bad people in our profession think they can keep the ‘wool pulled over the eyes’ of financial institutions, and the funders or guarantors of those mortgage loans.

In this case, the former appraiser had his licenses in Florida and Texas REVOKED in 2020. But then stole the identity of another unsuspecting appraiser, fled the US, hired ‘go-fers’ to get Florida subject and comp photos and data, then wrote, signed and submitted fraudulent appraisals after the revocation date.

The other sickening part of this, which is not mentioned, is that the ‘go-fers’ the convicted appraiser hired probably were akin to “gig workers” with limited education or understanding of what they were actually doing to assist the mortgage frauds activity.

The Power of Scatter Charts: Bringing Objectivity to Appraisals

by Scott Cullen

Excerpts:

“Objectivity is isolating the effect of individual variables on value.”

Once upon a time, in a suburban neighborhood not so far away, an appraiser came across a pure pair, two homes that seemed almost identical. They shared the same neighborhood, lot size and condition. The only difference was size. One house had 2,500 square feet of above grade finished area and the other had 2,300. The first sold for $460,000, the second for $446,000. The difference in price was $14,000. The difference in area was 200 square feet—producing an adjustment of $70 per square foot.

Traditionally, an appraiser might document this relationship as a simple table, noting the difference in sale price and living area. Unfortunately, pure pairs are so rare that they often seem like a fairytale—something every appraiser dreams of finding but seldom does. In the real world, properties rarely align so neatly. Markets shift, concessions appear, and location nuances creep in. Yet there is hope. By learning to use scatter charts, embracing adjusted pairs, and understanding sensitivity analysis, appraisers can move closer to true objectivity in their valuation work.

From Paired Sales to Sensitivity Analysis

The Appraisal of Real Estate, 15th Edition defines paired data and grouped data as forms of sensitivity analysis—a method used to isolate the effect of individual variables on value. Sensitivity analysis is the overarching principle that allows us to quantify how much one variable contributes to price, while holding others constant (Appraisal Institute, 2020, p.371). Scatter charts are among the most powerful tools available to visualize and calculate these relationships.

Why Visualization Matters

Scatter charts do more than calculate—they communicate. They combine mathematical precision with the clarity of visualization. For appraisers, this means turning abstract numbers into evidence that both clients and reviewers can see.

A well-constructed scatter chart illustrates the logic behind the adjustment and lends weight to the appraiser’s conclusions. It reinforces transparency: others can replicate the math, verify the trendline, and confirm that the adjustments are derived from observable market behavior.

As the saying goes, “A picture is worth a thousand words.” In appraisal, it’s also worth credibility. Scatter charts bring statistical discipline to the craft of valuation, grounding professional judgement in data.

Basement Appraisals: Understanding Contributory Value (Updated for UAD 3.6)

Excerpts: While homeowners may ask, “Does a finished basement add value to my appraisal?” you know the answer is a bit more complicated. A basement may impact a residential property’s value, and as an appraiser, you’ll need to evaluate its significance.

While determining the contributory value of basements isn’t overly complex, it does pose challenges. To help you out, we’ll outline essential steps and provide tips for evaluating a basement’s contributory value.

Summary

Determining how a basement contributes to a residential property’s value requires an appraiser to identify the basement type, its level of finishing, and any common concerns, like signs of mold or structural issues. Following best practices is key. This includes separating the basement from the above-grade finished area, understanding the intended use of the space, and completing comprehensive market research. By doing so, you can evaluate the basement’s contributory value more accurately

Topics include:

Types of basements (partial list)

Cellars

My comments: The best analysis and advice on basements I have seen. Watch the 7 minute video on Understanding Q/C ratings (UAD 3.6) Where I work the ground does not freeze. In my Island city there is no cemetery as the ground water from San Francico Bay is very high. Basements need pumps to remove salt water. Basement walls are not used to support the home. Sometimes there are above ground basements, basements dug out of the ground, and many other types of basements. In steep hillside areas what is a “basement” can be controversial.

In Alameda, my city, native American burials, primarily from the Ohlone people, are heavily concentrated in former shellmounds (ancient cemeteries) throughout Alameda. Almost were removed many years ago, similar to other Bay area cities close to the Bay.
