Big Data is the BuzzWord. Can We Trust Regression in Amenity Valuation? 14

Can We Trust Regression…

I would like to give a background as to what prompted this article. A few years back, word on the street was that the Collateral Underwriter was going to be using big data collected directly from our reports from the inception of UAD to aid in determining what should be “reasonable adjustments”. In order to be preemptive, I consulted an acquaintance of mine who just so happened to have a PhD in Statistics from Princeton. We worked through a number of real case scenario data sets to try and figure out if there was a way I could use regression...

Property Selection for analysis & Statistics in Appraisals - Appraisers Blogs 11

Property Selection for Analysis & Statistics

The importance of proper property selection and ‘statistics’ in appraisals… Appraisers, I would like to direct you to info written by Mr. George Dell in his latest blog post circulated on July 3, 2019. This is one of the best explanations I’ve seen him write on this topic, of how to select and analyze properties when doing appraisals, and why correct ‘statistics’ presented in reports is important. I first became aware of the importance of proper property selection and ‘statistics’ when I attended an appraiser’s training class in 2008 in Las Vegas. The primary speakers were Mr. David Braun and Mr. Patrick...

Should Appraisers Study Statistics? - Beyond the Old Inferential Statistics 11

Should Appraisers Study Statistics?

Yet what was (and still is) presented in appraiser education is the old inferential statistics. Difficult statistics. Convoluted statistics. Statistics for appraisers started to become a hot topic some 15+ years ago. I was more involved with the Appraisal Institute then, and often argued that with the changes in data sources — appraisers would have to learn to apply statistics. Around 2003, the AQB (Appraiser Qualifications Board) revised qualifying education to include the requirement for Finance, Statistics, and Valuation Modeling class. Although I was not solicited to write this class, I was put on the development team, which reviewed and suggested edits and improvements. The...

Didja Know... Zillow is Better than Eyes! - Discern Quality Using Photos 33

Didja Know… Zillow is Better than Eyes!

How in the heck is Zillow supposed to discern QUALITY of these homes, and then magically produce a presumed value, when there is no actual data upon which to base a decision? Maybe it’s done with smoke and mirrors, rather than eyes? Appraisers, I was busy churning out reports, and didn’t have time to send out this bit of news about Zillow earlier: Zillow is watching: New algorithm uses photos of your home to check quality and curb appeal. Zillow is now claiming “it” can discern QUALITY of a home, just by looking at various photos they obtain from various sources! They...

Is Race Baked into Big Data? Who's Regulating Big Data When It Errs? 18

Is Race Baked into Big Data?

Chicago appraiser and friend (even though she calls me “fancy pants”) writes a stellar explanation of what an appraiser actual does – and what one of the panel experts got completely wrong because he didn’t understand our role in the mortgage process: Greetings Congresswoman Waters, Chairman Clay, Ranking Member Duffy, Ranking Member Gooden, and the Members of the Housing Subcommittee: My name is Maureen Sweeney, and I am a real estate appraiser. I grew up in a real estate family and lived through the savings and loan crisis of the 1980’s, which had a profound impact on my life. I...

Race Never Considered... Emerging Narrative of Appraisers Being Racists 75

Appraisers Don’t Use Race

Appraisers don’t use race… Race is NEVER considered during a valuation Last week in a congressional hearing on the future of the appraisal profession, some research was used to suggest appraisers are showing racial bias and essentially undervaluing black neighborhoods. I was not expecting the conversation to go that way during the hearing and I’ll admit I’m deeply concerned about the emerging narrative of appraisers being racists… In the congressional hearing a panelist talked about a study that shows black neighborhoods are devalued by $48,000 compared to otherwise similar white neighborhoods. That’s alarming and society needs to have some serious...

MLS System under Cyber-Attack 3

MLS System Under Cyber-Attack

Appraisers, I belong to several appraiser forums, with active participation among appraisers. On Wednesday June 12, 2019, per a forum posting, the MetroList MLS (which uses Rapattoni data) was hit from an outside cyber-attack. This MLS provides service in central California around the Sacramento region. The cyber-attack caused property data to become unavailable via web sites – to appraisers and real estate agents. The MLS posted this message: The MetroList computer network that supports Prospector MLS is down as a result of a cyber-attack. The MetroList team is working at a very fast pace to resolve and restore services as...

Complain About a Complaint Filed - Who Can Complain About Appraisals 72

Who Can Complain About Appraisals?

Time to get on my soapbox and complain about a complaint filed against me (not a charge, but merely a complaint). I did an appraisal of a multi-family property near my office. The property owner/borrower called me to complain about the appraisal since it came in far less than she thought it should (not unusual). Clearly, I could not answer her questions since she was not the client. This upset her greatly, so she filed a complaint with the State. The complaint had no basis in substance. In fact, the complaint was that my appraisal was too low. Since neither...

Will the Cost Approach be Required in the Redesigned UAD Forms? 50

Returning to Requiring the Cost Approach

…the Cost Approach is the most INACCURATE of the three current ‘Approaches’ we use… Appraisers, for the past few weeks, emails have been sent by a third party asking appraisers to complete a survey about the appraisal process and the current forms. I did so; you should also. But I wanted to expand on one aspect of the survey. Two separate questions, on different survey pages, related to the Cost Approach (CA). These questions wanted appraisers to state their opinion about 1) if the forms provide adequate detail to develop a CA, and 2) if it is or is not...

Science & Art Reflect our Search for the Truth - Is There an Art in Science? 8

Is There an Art in Science?

We know there is science in art. Musical scales. Perspective and the golden ratio. The ordered sequence of a good novel. It’s difficult to be a good artist without knowing, or at least intuitively applying the truths found in the logic. Both science and art reflect our search for the truth. Our primal human nature is to resist the truth, even as it hits us in the groin. Resist the change. Fear. Give up something that has protected you. Something that gives you a place. A belonging. A prestige. An ego. A place where you are respected. Then someone or something comes along and says there is a better way. I...
