We get questions all the time about Zillow. My Zestimate says...I for one know that my Zestimate is wrong. I know what my house should list and sell for. (I'm not moving.) Do NOT think the Zestimate will be accurate. Nothing and no one can exactly predict what a home will sell for. That being said in the lower left corner of the Zillow home page there is a black section. Click on the 2nd word, "Zestimates". It will tell you how accurate they are. I'm not going to paraphrase but look over that section. They say you can change your home information. We/I haven't tried it yet, but if you do let us/me know how it goes.
