The homes posted here in Foreclosure are not for sale. RealtyTrac sells subscriptions to data, but not homes. The prices they post have no baring on what the home may actually sell for if foreclosure is completed and it either sells at auction or becomes bank owned and is listed with an agent.
These listings are a distraction and should be ignored. If you want to buy a home at a foreclosure auction, you'll need cash in hand and the capacity to buy without touring, inspecting or knowing for sure what you are getting. It's real estate speculation, so you also need to be able to take a loss if you make a bad purchase, as all sales are final.
