Zestimate disputes

How do I dispute my Zestimate?

We do not delete Zestimates. We monitor customer feedback for systematic issues with the algorithm, but do not change individual Zestimates in response to customer feedback. The Zestimate is designed to be a neutral, unbiased estimate of the fair market value of a home, based on publicly available and user-submitted data. For this purpose, it is important that it be based on identical information about homes (e.g., beds, baths, square footage, lot size, tax assessment, prior sale price) and that the algorithm itself be consistently applied to all homes in a similar manner. This ensures that there is no preference for some homes relative to others nor are there valuations based on facts that are not accessible to all Zillow users. Some homes may be very unique in ways that are not well captured by existing data, and the Zestimate may be less accurate on these homes. To provide more data on your Zestimate, you can post your estimated value and comment in the Owner Estimate section indicating your support for a different valuation.
