You can update the status of your listing within the My Listings section of your account to indicate that a property is sold or no longer on the market. Otherwise, a listing that we receive from a feed will generally remain live on Trulia until the feed indicates that the property is sold or once the listing information is removed from the feed entirely.
A listing that is submitted to us manually from this page must be refreshed within My Listings every 30 days to ensure that the listing information stays up-to-date.
