They have dropped the price zestimate on my house by $100,000 in the last 7 months. So it is now only two grand over what I paid for it, 10 years ago... Even though my neighborhood has exploded the last few years, new development all around me, literally. You can't even get a "lot" in my neighborhood, for more than 60grand of their zestimate. And my next door neighbors house, who has exactly the same house, is listed as having 2 more bedrooms and 2.5 more bathrooms? I had contacted them about multiple listings of my property and to remove interior photos from 4yrs ago. They sent me some bs form letter about their algorithms. The worst!
