This is just public record, which Trulia and other websites do quite a bit. The link in this thread actually already has the "sold" part included. That is a dead give-away.
Always remember, if it does not have a MLS# it is not listed! That is probably the easiest way to tell if something on Trulia is just tax records or an actual listing. Kinda confusing right!? If you would like I will just put you on the Realtor feed directly to the MLS that we all use for finding homes, and that way this problem will be taken care of (not to mention the time it will save you).
Just contact me if you want to receive all listings on the MLS in one simple email.
