Foreclosures posted here by RealtyTrac are rarely actually for sale. RealtyTrac sells subscriptions to information that a Realtor can provide for free. In reality, unless you are an active investor with cash in hand, it's not very helpful.
If you want to buy a home, consider all the inventory. A great local agent can help you find Bank owned homes as well as short sales and conventional sales. There may be good or bad deals among any of these.
