Listing agent can't or won't remove listing?

Sometimes what happens is the agent doesn't know how they put the listing on Zillow.  In order to determine this, open the property details page and scroll to the very bottom.   Look for a blue listing source or listing website.  Click on it.   This is feeding to Zillow and is the reason your house is still showing for sale.   Ask the agent (cc broker) to remove from that feed.    Do not mention Zillow, mention the feed and give the agent the url.

Before sending this information, google your address to see how many other sites have your home listed or sale.  (It may be shocking but will reenforce how critical it is for the agent to get it off the feed.)  

If Zillow removes the listing, the problem is an active data feed will over write their manual status change.   So, it has to be deleted from the root cause.

Once it is removed from the feed, it should disappear from Zillow within 72 h, probably 24 h.   Then you can claim your home, update photos and data.  (The other poster is incorrect, you can't claim your home if the agent is sending a feed.  Zillow has it set up so only one party can claim the home at a time.)

Good luck.
