You can find estimate calculators from various banks, realtors, etc. I just did a basic google search and checked out estimates from Zillow, Chase, and RE/MAX, and they range from 4% under my home price to 11% over. That's a pretty crazy range of guesses. My question is: why aren't these other home estimate calculators subject to being sued, then? (And when I checked out Zillow, I noticed there was a direct link to "I disagree" next to the Zestimate. None of the other calculators had any kind of feedback mechanism.) Seems like the journalist here forgot to mention that home estimates are pretty common and come from many different sources.
