Zillow Advice: Zestimates - My Square Footage is incorrect on Zillow and correct on Auditor Website http://www.zillow.com/advice-thread/My-Square-Footage-is-incorrect-on-Zillow-and-correct-on-Auditor-Website/375670/ Zillow Advice | Zillow Real Estate If your property is listed ... http://www.zillow.com/advice-thread/My-Square-Footage-is-incorrect-on-Zillow-and-correct-on-Auditor-Website/375670/ If your property is listed with a real estate broker, they may need to approve the changes.&nbsp; I am a flat fee MLS listing broker who is a member of the Realtors Multiple Listing Service for the Columbus area (called Columbus &amp; Central Ohio Multiple Listing Service or CBR MLS), and we receive emails notifying us when the owner has changed information on a property we have listed.&nbsp; <br/><br/>Don't worry about contradicting Zillow, they make mistakes just like anyone else (perhaps even more, they have lots of data=lots of chances to make an error).&nbsp; I would definitely make the change, just in case a potential buyer sees the listing on Zillow, which is statistically unlikely, but possible.<br/><br/>Thanks and good luck.
