Flag waving and appraisal. Huh? The Fourth of July is a day celebrating the anniversary of national independence. Appraisers are supposed to be impartial, objective, and independent. The new nation wanted independence from a King. Appraisers are to be independent of all the other participants in the real estate deal: buyer, seller, listing agent, selling […]
Is appraisal based on science? No. It’s an “opinion of value.” Yes. It’s a systematic method to learn about something. Looks like it’s both! – – – But wait! Is every opinion based on science? No. Does every method result in an opinion? No and no. So now we know how to talk about this. […]
And why are statistics and “data-centric” thinking suddenly a big deal? First, we need to know what data-centric means, and what statistics are needed. Here, we talk about what data-analysis tools and methods are needed to know, not clever academic mumbo-jumbo stuff. As many of you may know, I have spent the last 20 years […]
“Practical” means useful and sensible. And it should be somehow better than what went before. Artificial Intelligence learns from experience, recognizes patterns, and understands language. Today, most AI applications are “narrow,” in that they are intended to solve particular problems. For appraisal, this means formulating the problem, gathering relevant data, prediction, and presentation. Ai depends […]

The AI (Appraisal Institute) is experiencing pain. But it’s the result of sickness, instead of the growth pains of advancement. Why? As noted before, organizations tend to die due to one of two causes: Failure to respect its original, declared mission Failure to adapt to changing conditions. In the past, it was a world of […]
RStudio is an open-source user interface, designed for data analysis. It is not R. It does interactively access base R and other software such as Python, and has many packages which specialize on data collection, analysis, maps (GIS), graphs (ggplot2), and are used for managing appraisal assignments.

An organization can decline in one of two ways: 1) Failure to keep to its original mission; or 2) Failure to modify its direction in the face of change. The Appraisal Institute is the historical 1991 merger of the AIREA (American Institute of Real Estate Appraisal) and the SREA (Society of Real Estate Appraisers). Each […]
Why are adjustments a problem? The concept is simple. How does a typical buyer react (with a number), to a particular feature? For example, it seems to be easy to judge a person’s reaction to a house which is, say, 15% bigger. Economists use what is called a preference function to analyze this. This concept is […]
Time adjustments were often performed after other adjustments, particularly in upward trending markets, according to the December 2024 FHFA Working Paper. Editor’s Note: Read the entire series (so far) here. Some appraisers were avoiding time adjustments, unless needed for another purpose! That purpose is when the appraiser couldn’t match the user-lender’s expectation of value (an “underappraisal”). […]
A timely recap of Time: The FHFA working paper 24-07 provided four strategies used by appraisers to satisfy the prior Fannie Mae and Freddie Mac Selling Guide requirement for time adjustments. The strategies comprise: Grouped data Paired sales Indexed similar-sales Avoidance Editor’s Note: Read the entire series (so far) here. The Appraisal Institute News Release of […]
“Other commonly accepted methods” is the fifth and final “acceptable method” per the Fannie Mae Selling Guide, for time adjustments. Editor’s Note: Read the entire series (so far) here. The FHFA working paper 24-07 listed “common strategies” used by appraisers, whether reliable, understandable, or not. The GSE guideline simply notes some acceptable “methods.” “Commonly accepted,” in […]
Paired sales is the fourth of five “acceptable” methods for time adjustments, according to the Fannie Mae selling guide. Once again, the method is neither defined nor explained. Editor’s Note: Read the entire series (so far) here. A look at USPAP shows no reference to grouped or “paired sales” as a way to support an opinion […]
In this part, we look at modeling, the third “acceptable method.” What kind of a method is “modeling”? That’s pretty broad. Editor’s Note: Read the entire series (so far) here. A common definition of “model” is “a small representation of something.” More formally, it’s “an abstract/logical depiction to improve understanding of prediction.” The Fannie Mae GSE […]
Statistical is the second “method” mentioned in the Fannie Mae Guideline for time adjustments. Editor’s Note: Read the entire series (so far) here. What does that mean? Is it an actual “acceptable” method? It says so. It must be! Let’s look. The Fannie Mae Guidelines do not explain the word, nor the process. We must look […]
