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.
(For example, a house we looked at was $430,000 one day and only $360,000 on another day.). CONCLUSION: Zillow never claims that one should use the zestimate tool as a replacement for an appraisal. Zillow encourages you to use the calculation as a good starting point in researching the value of your home.se the Home Value Estimator at Chase.com to get a free estimated market value of your home or the home you are interested in.
