Actually that is pretty fast compared to many sites that i hear about. Most sites, including trulia have some out of date data on the status of property. It's better than tax records which tend to be 6mo+ behind.
I'm happy to update you on homes that have sold in your area. Trulia is not the best way to get current market information. An agent is the best source of data and knowledge to determine market values. Please let me know if I can be of assistance.
