What is a Drive-By Appraisal?

Excerpts: This method bypasses traditional in-person appraisal methods and has grown in relevance for situations like refinancing or low-risk loans where a full interior inspection may not be necessary.

In addition to observing and evaluating the property’s exterior condition, appraisers will also assess the surrounding neighborhood, use MLS listings for home interior information, and evaluate comparable sales data to estimate property value.

Also known as “exterior-only appraisals” or “2055 appraisals,” this approach is often chosen when a full appraisal isn’t required, such as for low-risk lending scenarios or when lenders have sufficient market data to support a valuation without an interior inspection.

They are also used in situations like foreclosure when interior inspections are not possible.

My comments: Definitely the most comprehensive and understandable article on drive-bys I have read. I did many drive-bys in the 80s and 90s for lenders. I finally quit doing them on 2-4 unit properties with little info available. Also, when appraising large Victorians I did not know what had changed since 1910. Permit histories in my city are very limited prior to 1950.

I did a lot of foreclosure drive-bys when prices were dropping. I did full appraisals with interior inspections after they were foreclosed.

My most difficult drive-by was a house that was completely “trashed” after the death of the owner by a young relative drug user. It had been sold after renovation and I had no access. I interviewed relatives, neighbors, etc. to try to find out what it was like on the date of death. I always ask the estate trustee to get me access to the house before any changes are made if possible.

BE CAREFUL. DO NOT UNDERBID ON DRIVEBYS.

TOO MUCH UNCERTAINTY ABOUT THE INTERIOR CONDITIONS.

Experiences with Firearms as an Appraiser: When Tenants Behave Unexpectedly in “Their Area”

Excerpts: Appraisers often find themselves in a wide variety of settings and situations. I mean, we are entering people’s homes, somewhere that most people see as their comfort zones and a place they are not open to having a stranger poke around in. We as professionals understand this and usually try to make it as quick and painless as possible. There are those moments where it turns into a “memorable experience” and homeowners or tenants feel like they must make it known we are not welcome.

I personally am batting .1000 this year on multi-family properties, where tenants have felt it was necessary for me to get the message, by brandishing a firearm. I will share the following two situations, how I personally managed it, explain why I do not personally carry a concealed firearm, and ask you readers to tell me if this is common or for similar memorable experiences.

For more information and to read the appraiser comments, Click Here

My comments: My first appraisal-related job was with the Monterey (California) County Assessor’s office. It was transitioning to computerized valuation. I was a temporary “appraiser assistant” hired to go to properties to see if the county appraisal records needed updating.

In those days (mid-1970s), properties were reappraised regularly to increase the assessments and property taxes were increased.

I knocked on the door and was met with a man carrying a shotgun. He said: Go away assessor! I don’t remember the city, but it was not in a rural area. I left and told my supervisor to find someone else to do the inspection.

I have never owned a firearm and would never carry one. No one I knew owned a firearm except for my husband, who had firearm training when he was teaching horticulture at a state prison. I would not allow a firearm in our house but still keep a baseball bat by my front door “just in case”.

But, recreational firing at a target was on my “bucket list”. An appraiser friend took me to a local firing range. I tried handguns, rifles and shotguns. Some worked like machine guns with many bullets fired at one time. I really liked it the best. Next time I go to Las Vegas I will try out real machine guns. Trying to hit a target did not appeal to me. Ya never know until you try!

Of course, I have had many encounters with dogs. One was when I was appraising the house of an appraiser I knew. I was met with small dogs biting my ankles. When the owner put the dogs away I continued with the appraisal. Another time, in a rural area, 3 large Dobermans broke down the door of a mobile home and ran toward me. I managed to get in my car. I told the lender to get another appraiser.

When markets crashed I did a lot of foreclosure appraisals. I made a lot of noise opening the door and loudly saying I was an appraiser for the lender and needed to come inside. I never had a problem. But some appraisers requested that a police officer accompany them when the home looked “sketchy” to them from the outside.

Why Is the Square Footage in Public Records Different from the Appraisal?

By Tom Horn

Excerpts:

Why Accuracy Matters

Square footage is one of the most critical factors in determining a home’s value, yet it is often misunderstood. Many homeowners and real estate agents assume that the square footage listed in public records is accurate, but that’s not always the case. When an appraiser measures a home, their calculation often differs from what’s in tax records. These discrepancies can lead to confusion, mispricing, and even appraisal challenges.

Why Square Footage Discrepancies Occur

Public Records vs. Appraisal Measurements

The square footage listed in public records typically comes from the county tax assessor’s office. Assessors determine square footage based on:

Builder-reported figures:…

Estimates or outdated records:…

Conversions and Additions

Another common reason for discrepancies is home modifications. If a homeowner adds square footage without the proper permits, tax records may not reflect the change. Examples include:

Unpermitted additions:…

Incorrect classifications:…

My comments: Worth reading. Written for non-appraisers but the best explanations I have ever read about this topic. I worked for an assessor’s office for my first 4 years of appraising, starting in 1975. I was given a geographic area and appraised every residential in it. Fantastic experience. I learned a lot. I was very lucky. Very different than lender appraising, where you only appraise properties that are suitable for mortgage loans.

The Limits of AI: When the intelligence is artificial, common sense is a superpower

By John Russell

Excerpts: At some point, all of us will integrate AI tools into our business practices. Whether it automates mundane and repetitive tasks, generates narrative text, or assists with analyses, the power of AI to save time is real.

The good news for valuation professionals is they have lots of experience spotting data points that don’t jibe with what they know. Another way to say this is that they have common sense. It’s a basic requirement for doing the work. Of course this 3-story overbuilt McMansion is probably not a comparable for a Cape Cod two miles away. That sale was under atypical conditions and, at minimum, needs adjustments to even be considered. You get the idea.

Do I trust what the AI is telling me?

Accepting AI outputs without any skepticism is a recipe for disaster. Approach AI like a detective interviewing witnesses: trust, but verify. Basic internet searches can quickly fact-check results — or raise enough red flags that you reject what is being offered. No state board will accept the argument, “But ChatGPT said,” and neither should you….

Should I be using AI for this task?

Just because you can doesn’t mean you should — commit this phrase to memory. You will have to own everything in your report, and if too much of the product is driven by AI tools, you may be asked: “Well, what exactly did you do here?”…

Common sense is a superpower that can protect you from dire consequences as you experiment with AI. It’s tempting to be spellbound by new AI tools that seem miraculous — and to let down your guard of common sense. Instead, I recommend a heightened sense of caution: The tools are only as good as the people who craft them and the inputs provided by the users. AI hallucinations are still unpredictable, inevitable failure points, which means any “facts” and analyses it supplies should always be verified — it’s just common sense

Excerpts:

Environmental Hazards

While Fannie Mae does not expect the appraiser to be an expert in the field of environmental hazards, we do expect appraisers to analyze and report any information about environmental hazards that is available in the normal course of business…

If an appraiser has knowledge of or identifies an environmental hazard in or on the subject property or on any site within the vicinity of the property, we require the appraiser to…

Seller Concessions

The article about seller concessions in our December 2023 Appraiser Update generated a lot of questions and buzz.

First, we heard that some appraisers, in reaction to our article, adopted a practice of always adjusting dollar for dollar for seller concessions. While this may seem sensible from a theoretical perspective, it could have adverse unintended consequences (such as undervaluation) if the concession did not actually have a dollar-for-dollar impact on the price. Making either assumption (that there is no impact or that the impact is dollar-for-dollar) is not the correct approach…

Top 10 Things Appraisers Wish Real Estate Agents Understood

McKissock Survey

Excerpts: Survey question: “What’s one thing you wish real estate agents knew about the appraisal process?”

Based on the answers we received, appraisers wish that agents knew the following:

  • The appraisal process is complex and takes time
  • Appraisers do not assign value
  • Appraisers are unbiased and must follow guidelines
  • Appraisers need their input and cooperation
  • How to select appropriate sales comps
  • The importance of providing accurate and detailed info in their listings
  • How to determine correct GLA (gross living area)
  • How renovations and upgrades affect value
  • How to prepare for the appraisal appointment
  • FHA/VA/USDA guidelines

Sample appraiser answers:

“How complex it really is. We don’t just pull numbers out of the air—they are market supported adjustments backed by ‘many angles“

Some brokers regard the appraiser as an adversary, who potentially can ruin their deal and end up without commission. They should learn that the appraiser is neutral and cooperating can be a benefit.”’ of research.”

“Entering an occupied home without agent or home owner present is a liability issue for appraisers—[we] need someone present to observe what we do.”

My comments: Read the blog post and maybe get some good ideas for answering agent questions!

Many years ago a top local agent asked me why I was driving around taking photos. I explained they were similar homes (comps) I may be using in an appraisal. I realized she did not know much about what appraisers do.

When I started my appraisal business in 1986 I did presentations at all the local real estate offices, usually during their marketing meetings. I explained what appraisers do and how agents and appraisers can work together. They liked the information.

What Is an Appraisal Review and Who Can Be a Reviewer?

Excerpts:

Topics:

  • What is an appraisal review?
  • Fact-checking vs appraisal review
  • Types of appraisal review reports
  • Why are appraisal reviews needed?
  • Who requests a property appraisal review?
  • Who can review a property appraisal?

The client base for appraisal reviews is vast and diverse, encompassing a wide range of sectors and needs.

  • Lenders rely on reviews to ensure the accuracy and reliability of appraisals before making lending decisions.
  • Investors use them to evaluate the value and risk of potential investments.
  • Attorneys order reviews to support legal matters involving property valuation, including disputes and condemnation cases.
  • Insurance companies use them for verifying property values in underwriting and claims.
  • Government agencies may request reviews for regulatory purposes, tax purposes, or right-of-way acquisitions.

My comments: Comprehensive info on reviews. Short and well written. The best I have read, whether you are a reviewer or an appraiser being reviewed. Reviewing is an excellent option for fee appraisers and staff appraisers.

Personally, I quit doing lender reviews many years ago. I preferred to do the appraisal rather than reviewing an appraisal where I have to also appraise the property. Back in the “old days” I reviewed competent local appraisers I knew.

The final blow later for me was a 4 unit property where the appraiser appraised it as a home. There were 4 electrical meters and lots of cars. When I called my client, they just wanted to know if the value was the same as a house or 4 units. I did not reply. It was my last review for lending purposes. I verified with the city that it was a 4 unit property. There was no information that it had been converted to a single family home. Mortgage rates and requirements are lower for SFRs.

On the other side, many appraisers who do lender reviews say they learned a lot about how appraisers appraise.

Value of a Pool

What is a pool worth? It depends.

By Ryan Lundquist June 26, 2024

Excerpts: With and Without Pools (Big Difference)

There’s a huge difference in the stats when we compare homes with and without pools. The properties with pools are larger in square footage and lot size, higher in price, and they’ve taken slightly less time to sell too.

In short, the higher the price, the greater chance there is a pool. This likely has to do with the cost of building a pool, cost of maintaining a pool, and even larger parcels at higher ranges – not to mention buyers at higher price points expecting a pool more often.

The rhythm of pool sales basically follows the pattern we see in the entire market. More sales as the year unfolds, and they typically peak around June. Some smaller areas could be slightly different.

Seriously though, What is a pool worth?

It depends. Different price points and locations come with different expectations. There isn’t a one-size-fits-all answer for the value of a pool. In other words, we can’t just apply one figure to a property because that number isn’t going to make sense everywhere. This is where we have to study the comps. With that said, my observation is pool adjustments have generally gone up since the pandemic as buyers are more in tune with the importance of a backyard. Have you seen that also?

To read more, Click Here

My comments: Check out Ryan’s tables to see his data analysis, which is not difficult to set up.

When I first started appraising in suburban Bay Area cities in the mid-1980s, homes with pools sold for more in some neighborhoods with higher-priced homes. MLS always said a pool was there, which is a good way to check it out. At that time, MLS data analysis was much more limited than it is today. I saw this in a particular neighborhood with very hot summers. This is still the same now.

In contrast, where I live, about 15 miles west, on an island on San Francisco Bay, pools have never been a plus or a minus. Weather is “Mediterranean” weather without hot summers. Often sellers said they would remove the pool, but the buyers never requested it.

AVM Accuracy?

Bank AVMs Are As Wildly Inaccurate As A Zestimate – But Will Be Regulated As Legitimate Values

By Jonathan Miller

June 24, 2024

Excerpts:

  •    AVMs are incredibly inaccurate and are being misused in property valuation
  •    AVMs don’t consider the condition of a home
  •    The mortgage industry’s push toward automation has reduced valuation accuracy

AVM or Automated Valuation Models have been incorrectly seen as the human-less way to value property. The technology has been drifting into mortgage lending reliance for more than a decade because it has been marketed as having the ease of “pushing a button.”

The Zestimate product by Zillow introduced the consumer to the concept nearly twenty years ago…

The recent ruling to regulate the credibility of AVMs by the OCC and FDIC essentially legitimized the use of AVMs in lending. The driver behind this final rule was to eliminate potential bias in valuations by replacing appraisers with AVMS. Yet the Urban Institute study Revisiting Automated Valuation Model Disparities in Majority-Black Neighborhoods said: But even with data improvement and artificial intelligence, we still find evidence that the percentage magnitude of AVM error is greater in majority-Black neighborhoods. This finding indicates that we cannot reject the role historic discrimination has played in the evaluation of home values.

AVM software is built by humans who have inherent biases. The void in representation by the appraisal industry over the past decade on the AVM issue, to talk about those 200 feral cats living in the house being valued, has enabled AVMs to be legitimized by the federal government.

During my career, I have observed that valuation accuracy has become weaker as technology has expanded in the mortgage process. The wiz-bang concept that the appraisal of a property can be completed at the push of a button is missing the realities of valuation.

My comments: Worth reading. Miller was involved in AVM history and, as usual, has some very interesting stories plus lots of Zillow comments.

Miller used to send out a very long post once a week. I often just scrolled fast through most of it to get to the appraisal section, but I missed a lot that was worth reading. Now, he has divided it into daily posts.

What is a Complex Residential Property?

How to Identify a Complex Residential Property

By Dan Bradley

Excerpts: A complex one-to-four family residential property is defined as a property that meets at least one of the following criteria:

  •   The property to be appraised is atypical
  •   The form of ownership is atypical
  •   The market conditions are atypical

Some of the key physical features that can make an appraisal assignment complex include:

  •  Size (significantly larger or smaller than typical for market)
  •   Floor plan (there may be functional obsolescence)
  •   Unique custom features
  •   Quality of workmanship or construction (higher or lower than the norm)
  •   Architectural design
  •   Adequacy of HVAC, electrical systems, well and/or septic
  •   Additional living unit(s)
  •   Non-conforming zoning
  •   Mixed-use property (for example, it is used as both a business and residence)
  •   Waterfront properties

Keep in mind that what is considered a complex residential property in one market might not be considered complex in another market. For example:

  •  A mansion in Beverly Hills is not atypical; a mansion located somewhere in rural America might be
  •  A log cabin in the mountains of Virginia is common; a beach-front log cabin in VA, not so much
  •  Manufactured or mobile homes with additions are common in rural areas, but generally not in cities

My comments: Read this short article and keep it available. Very good lists of the factors.

Why do you want to know about this topic? Business is slow now, which is a good time to try appraising unusual homes. But, a fast turn time is not a good idea unless you are very familiar with the subject’s complexities. Do you have another appraiser who can help you? Don’t risk your appraisal license by getting in “over your head”. I get regular calls from appraisers who said “yes” but did not have anyone to advise them.

Very few appraisers, if any, would have experience on all these types of properties. For example, I have appraised many life estates, but no homes with a leasehold (ground lease) in a market area where such interests are uncommon. I have only appraised homes where the subject and all the nearby homes are leaseholds. I get advice for appraising it.
