If you check out Realtor.com, Zillow.com, Help You Sell and For Sale By Owner web sites, I'm sure you will see all this information. I know it's available in the MLS.
The problem with the other sites (I have emailed them and complained about how the search isn't working properly) is that when you request specific criteria for the search it doesn't eliminate the unwanted. For example, if I requested a 3 car plus garage, this is all I should get, but no I still get the one car and two car garages.
Hope you people can do better, we really like your system so far and yes we are shopping for a house, it'll be our last and we'll be buying in late 2009 or early 2010. Doesn't hurt to look early, especially when it's our retirement place.
