You can search for homes on this site and others and you will find a mixed bag of homes that are for sale, homes that have been sold, homes that are not on the market, postings for foreclosures that you cannot buy because they are not on the market and other items of interest.
My suggestion is that you associate yourself with a local Realtor who is knowledgeable in the market in which you want to buy. Sit down with the Realtor and discuss what it is that you are trying to accomplish. Learn about the condition of your local market, the availability of houses in your price range, and what it will take to achieve your goal. Get preapproved for financing if you are not a cash buyer so that you will be ready to make an offer when the right opportunity presents itself.
