How Accurate are Zillow’s Zestimates?
Wednesday, February 21st, 2007Apparently Zillow offers fairly accurate estimates on the market value of your home.
In the year since its launch, Zillow Inc. has made millions of Americans familiar with computer-generated estimates of home values, created a new online addiction and become a staple of dinner-party chatter.
But just how accurate is it? A Wall Street Journal analysis of 1,000 recent home sales shows that Zillow’s “Zestimates” often are very good, frequently within a few percentage points of the actual price paid. But when Zillow is bad, it can be terrible — off the mark by more than 25% on one in 10 homes. In one case it was off by $2 million.
Zillow, based in Seattle, operates a Web site that offers free estimates and other online tools for real-estate buyers and sellers. It draws revenue from online advertising. from:
