Try this, i've found this:
You can remove a rental listing from Trulia in a couple of ways.
If the listing was manually submitted you can remove the property through your account page. Simply Log in to Trulia.com, hover your mouse pointer over your name in the top right corner of the page. The site navigation menu will appear as a drop down menu, click on "my listings". Once in the listings page choose the "for rent" tab. Your property will appear with an "edit property" button. Hover over the edit listing button and from the drop down menu select delete property. To remove it from the site select the deleted folder and select the delete forever button next to the listing you wish to remove from the site.
