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...

Zillow in Crosshairs - Zillow Has the Most Flawed Business Models 8

Zillow in Crosshairs

Steve Eisman, the hedge-fund manager famous for betting against the US housing market in 2008 explains why he is shorting online real estate company Zillow. “I would say Zillow has one of the most flawed business models I’ve seen in a very, very long time,” he said during an interview on CNBC. “They had a good business which was their internet real estate platform. The growth in that has slowed dramatically so that now the growth is zero… The most problematic is what they call their, I believe, iHome business, an internet buying business where they actually go out and...

White Swan Predicts that the Next Recession Is Inevitable 10

The Black Swan – Another Meltdown

Another Meltdown – The Inevitable Outcome of a White Swan: Why would we allow another Financial Meltdown to occur? …When revenues and profits decline, lenders and financial institutions throw caution to the wind and relax their once prudent lending policies in favor of more aggressive, inclusive policies… Hindsight has taught us that there is no serious consequence to imprudent lending policies. Perhaps a multi million dollar fine is assessed but that is just the small cost of doing business for some violators… Though more common now, especially in Australia, Europe, and  Asia, black swans (Cygnus atratus) were once thought to...

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...

Why Not Qualified Appraisers Instead of Cheap Appraiser Imposters? 29

Appraiser Imposters!

AMC sends a “non-appraiser” to photograph, measure, sketch, and observe a property, it’s quality, condition, and surroundings instead of using a qualified appraiser… I’m not an Appraiser, You just think I’m one Ever see the AT&T commercial where the surgeon walks in and he says “I Just got reinstated, Nervous? That’s ok so am I”. If not see here: https://youtu.be/1YT3erQZoq4   Or the late 1986 commercial with Peter Bergman that states I’m not really a doctor but I play one on TV.   Well get ready Consumers because the person that is about to visit your home IS NOT an...

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...

Appraiser vs Machine - The Appraiser Cannot be Replaced by a Machine 5

Appraisers vs. Machines

Collateral risk analysis (appraisals being a key element of that) is partially art, partially science. Those two facets are blended inseparably, like a soup…the ingredients can’t be separated. While computers can undeniably perform certain tasks better than humans (such as the handling of large amounts of data) appraisers can perform other absolutely critical aspects of the process better than a machine. The appraiser can actually see the property to be valued, they can utilize their human senses, they can use their judgement based upon what they observe by physically being at “ground zero” (the Subject property), and can then apply...

Another Huckster Enters the Appraisal Arena 20

Another Huckster Enters the Appraisal Arena

Yet another third party huckster has entered into the real estate appraiser and appraisal arena. It’s that time again! Yet another third party huckster has entered into the real estate appraiser and appraisal arena. Apparently motivated by pure altruism. We identified a need in the marketplace to address a common problem that lenders are regularly challenged with in providing accurate appraisal quotes and then ensuring pricing on the Loan Estimate is consistent and compliant,” stated Vladimir Bien-Aime, president and CEO at Global DMS. (I LOVE this guy, he writes like me!) Global DMS Launches SnapVal to Provide Instant, Accurate, Guaranteed...

Cyber Threats Are Real Risks to Appraisal Firms. Corelogic's Data Hacked 17

Cyber Attacks on Corelogic

Recent Cyber Attacks on CoreLogic and a Large Appraisal Firm Expose a Real Business Risk to Valuation Firms and Companies. As two recent attacks show, cyber crimes pose a real risk – legally and economically – to appraisal firms, management companies and other businesses involved in property analytics. If an operation like CoreLogic can be victimized by criminal hackers seeking property information, as it was in an attack earlier this month, any valuation firm or property analytics company is at risk. And, more seriously, the losses suffered by an appraisal firm in the separate cyber attack discussed below demonstrate how...

What If the Algorithms Are Wrong? Weapons of Math Destruction... 12

What If the Algorithms Are Wrong?

Algorithms are everywhere… “Algorithms decide who gets a loan, who gets a job interview, who gets insurance and much more — but they don’t automatically make things fair. Mathematician and data scientist Cathy O’Neil coined a term for algorithms that are secret, important and harmful: “weapons of math destruction.” Learn more about the hidden agendas behind the formulas.” “Algorithms are opinions embedded in code. It’s really different from what you think most people think of algorithms. They think algorithms are objective and true and scientific. That’s a marketing trick. It’s also a marketing trick to intimidate you with algorithms, to...
