When you consider that 17% of Zillows 100 million plus Zestimates are more than 25% inaccurate it is outrageous that they can peddle nonsense Zestimates the way they do. Think of the misery and potential financial damage that homeowners, suffering with an unwanted imposed erroneous Zestimate, and Zillow refuse all reasonable requests to correct or delete the nonsensical valuation that their flawed algorithm computes. When Zillow says that Zestimates are a "starting point" they are mis-leading as when Zillow refuse to correct Zestimates they become an "end point" too.
Even more interesting is that our elected representatives have failed to introduce any form of Regulation on Zillow and other AVM companies for the damage they cause to homeowners, as well as the chaos and confusion that incorrect Zestimates create in the home sales business. At the very minimum there should be a DoNotZestimate website that homeowners can opt out of Zillows nonsense in the same way as phone users can register with DoNotCall to opt out of spam phone calls.
