Alerts are a great way for you to stay up-to-date on things you care about. We will email you a list of the new items that match your criteria at a time of your choosing.
Much of the data used on the site comes from public records, so in a lot of cases we can only be as accurate as that information.
With regards to Zestimate accuracy, we actually publish our accuracy rates for all counties in the US. You can find the chart here. The err rates are calculated by looking at the Zestimate the day the property sold, then calculating the delta.
Also, we include a value range on many of the properties on the site, which take the err rate into consideration. The higher the err rate, the bigger the value range can be.
Finally, there is also the functionality for the owner of the property to create and publish an Owner's Estimate on the site. The owner can update any home facts, tell us about a recent renovation or a view that a computer would have no way of knowing about, or select different comparable homes. Doing this can create a different valuation, which can be published to the site.
