There was no link or property address referenced in your question. However, the way to buy any home, is to contact a local Realtor. He/she will have access to all listings in the MLS, which is the best source of available properties. There are many foreclosure listings on here that are bogus listings. Steer clear of Realty Trac. Here's a tip: All available properties (including foreclosures) will be in your local MLS and any Realtor can assist you in purchasing one.
But I would ask yourself why buy a foreclosure? It's not always that great of a deal. I'm sure there are available properties in your area, and in your price range that won't have the hassles that a foreclosure will.
