Zestimates: Improving accuracy. Zillow says Zestimates currently have a median error rate of 8%. That may seem to be a large margin â but it has improved. The algorithm began with a 13.6% median error rate in 2006, according to Zillow. However, error rates can vary widely, depending on where you live.
I applied their median error of 6.1% to Zillowâs own estimate of the median sale price in the U.S. in May 2016 of $229,737 and got a typical error of $14,000. The typical Zillow Zestimate error is $14,000, but you donât know if itâs $14,000 too high or $14,000 too low. And it gets worse because HALF the time Zillow Zestimates are off by MORE than $14,000, sometimes a LOT more than $14,000.
