I bought my home for 139,000 4 years ago. The bank appraised it at 155,000 while i was buying it (also 4 years ago). The town has it appraised at 178,900 since 2011 Zillow's "Zestimate" has it at 134,500 If we go by the "market" rate of what it would/could actually sell for then Zillow is the most accurate out of all those estimates. Now I've done quite a bit of interior work to the house and Zillow's is most likely off by quite a bit now that my house has a new kitchen and bathrooms but I'm not sure how it could take that into account since there's no way for that data to reach Zillow.
