Why can’t I edit my Zillow listing after my property goes live on the MLS?
Once your home is listed on the MLS, websites like Zillow, Redfin, and Realtor.com automatically pull your listing data directly from the MLS.
Because of this MLS connection, Zillow removes homeowner editing access to avoid conflicting information online. This is a Zillow policy that applies to any home listed through the MLS — regardless of which agent or company lists it.
