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.
This figure is essentially what Zillow thinks the property will sell for, and is represented as a dollar amount and percentage relative to the Zestimate. They tend to be estimated to sell below the Zestimate, which makes sense given that they are foreclosures.
