Unfortunately trulia and quite a few of the websites put homes that are for sale on their site. Were they get the information I don't know as a lot of the times it is incorrect. Unless your agent has a subscription to trulia they would not be able to change it and just so you will know it is not your agents fault as this is quite common. You can join trulia for free as an agent and make the corrections yourself however. Good Luck on selling your house.
