It finally happened. And I think I speak for my peers when I say that I am pretty excited.
Zillow is facing a lawsuit over their Zestimates.
The Washington Post reported that an angry homeowner whose Zestimate was lower than the value of their home has sued Zillow in court in Illinois.
The suit basically states that:
a) the estimate of the home’s value constituted an appraisal and that Zillow is not an appraiser,
b) she did not consent to her home’s value being published online, and
c) the publishing of an appraisal of her home online without her consent constituted a ‘substantial roadblock to the sale of her home.’
We will see how it all shakes out.
The Zestimate is Finally Under Fire
Here is the takeaway:Zillow’s use of the Zestimate as its primary competitive advantage is now under fire and the increased exposure will likely shine light on the inaccuracy of the practice. If agents had a nickel for every time that a Zestimate was incorrectly used by the public (and appraisers) we would have all retired by now.
Statistics Are Not Absolutes
The Zestimate is stated as an absolute. In other words, Zillow’s estimate effectively says that the house is worth $X without disclaiming how confident they are in the valuation or how they arrived at the valuation. They also fail to disclose which comparable sales are being used in the analysis.
In true statistical analysis, an estimate is disclaimed by the confidence in the accuracy of the estimate. In other words, a true statistical estimate should be stated as follows: ‘We are 90% sure that the value is between $300,000 and $330,000 and we are 95% sure that it is between $270,000 and $360,000.’
If that was all Zillow had to offer, their company would not have become nearly as successful.
Even the Fine Print is Wrong
It seems that Zillow’s practice of burying accuracy information 4-5 clicks deep on their website and not disclaiming estimates with confidence interval and standard deviation statistics is finally catching up with them.
If any other company buried their fine print as deeply as Zillow does, they would already be out of business. Can you imagine a Realtor, lender, or other financial service company offering a disclaimer about their services 5 pages deep on a website?
Zillow Needs to Play By the Rules
To the person pursuing the suit, I say good for you. And to those who may join in a class action suit, I say go get ‘em!
Zillow is a magnificent technological tool that has brought a great deal of change to our industry, some of which has actually been positive. But many of their practices will prove to be damaging to the industry in the long run.
Zillow is technically not an agent or an appraiser, and thus they get to play by their own set of rules. Agents, lenders, and appraisers would all lose licensure if they acted in the same manner as Zillow.
When they take the information that Realtors have all worked so hard to gather and curate, and sell it to any and all for whatever price, it destroys the very asset that we have all — agents, appraisers and of course, the public — come to rely on so heavily.
I am thrilled that someone has finally called their bluff.
