When I click the link, it does say that is has expired from C21 or is no longer available. If you would like it to show you as the listing agent, you need to go to your account in Trulia and brand the listing to you. I believe you can search for the address or MLS number and then check the box to brand it to your name.
Let me know if that doesn't work for you. CJ Dubois-Cote, Prudential Prime Properties, 207-615-1663 or email@example.com
