Homes do not often come off as quickly as they appear. When I list a new home it typically takes 2-3 days to show up on Trulia.
For that reason sites like Trulia and Zillow are great for generally looking but when you are in a position to buy you really need to be looking at direct MLS information. When I sign up a client for a search they get information on new listings as soon as they hit the MLS.. no delay. So make sure your Realtor sets up a search for you using their MLS access so you don't miss anything. Finding the perfect home 3 days after it went into the MLS puts you at a severe disadvantage to those actively looking at homes in real time.
Best of luck to you.
