Is Zillow Accurate in Areas Like Dallas-FT Worth?

[Michael Petrovich]

Hello BP!  I understand that Zillow's algorithms use information from areas that may over-extend the boundaries of the primary area of sale to come up with an estimated sales price. So, Im sure it can be off.  But... In highly populated areas, with lots of sales in that zip or part of town such as... lets say, Ft Worth (picking on the DFW for those who have knowledge of the area)... can it be CLOSE to accurate on home prices?

Jay T from Zillow here. The Zestimate is quite accurate in some places, and not terribly accurate in others. It's really more a function of available public data rather than size of the market.

Since Texas is a "non-disclosure state" the accuracy of the Zestimate suffers somewhat.

We publish accuracy data down to the county level here:

Just click on "states/counties" in the accuracy table, then click on a state to get the county-level data.
