What Is A Zestimate and Why It Isn’t Accurate Niko Apostal 12/27/17

Many online home selling websites have ways to help you estimate the value of your home. Zillow’s computer algorithm technique known as a Zestimate, as well as other online estimates are not accurate. Here’s why.


These computer algorithms are known as automated market values. They are based on certain data going in so that a value can be computed. However, the data going in isn’t always correct.

Here in the Chicago area, the data is skewed due to tax values. These tax values vary greatly from house to house, even in the same neighborhood. Since a Zestimate sticks to public record values, their estimates will never be as accurate as an agent’s.
