I plugged in a few locations at the Zillow website and every day I get notifications of homes/condos for sale in my price range and the size I'm looking for. It's a great feature when trying to get ideas of what is affordable and where in a city it is located. Usually you get pics of the home and a map telling you exactly where it is located. They tell you when it last sold, how much, and also the taxes. You can also check your own neighborhood for sale information.
