Niki from Trulia here. We are excited that you are using Trulia for your real estate needs. The listing at http://www.trulia.com/rental/311633445
is no longer active on Trulia.
To remove a rental listing from Trulia, the status update should be made in the source site. If the listing was manually submitted there will be a delete option when you are in "My Listings". If the listing was syndicated to us from another site, the status should be re-syndicated when the source site is updated.
We are actively working to filter out incorrect or inactive listings from our site and appreciate your patience as we continually refine our process. We hope your experience with Trulia is memorable and thank you for using Trulia for all your real estate needs.
