I understand your frustration. Unfortunately, this isn't something controlled by the agents, but by Trulia. We don't actually upload our listings, but Trulia retrieves them from the multiple listing service. We also get frustrated and don't know why they are still on here. What I have noticed is if they are sold, it will say it in the web address at the top. Hope that helps somewhat. Please let me know if I can be of any assistance.
