Go to http://www.realtor.com and search for foreclosures OR ask a local realtor to help you.
Any time you see a listing that says sign up for a free trial you are being taken. The foreclosures really for sale are listed free and any realtor can see them and send you those that fit your needs.
We don't see any property referenced, but would assume that you are referring to one of the pre-foreclosure listings. If that is correct, then the amount listed for these is usually the amount that the owner is in default - the asking price would be considerably higher when the home is actually listed for sale.
As far as the costs involved in the purchase of a home... If you are obtaining FHA financing, you would have your 3.5% down payment, any closing costs that we can not get the seller to pay and the costs of your appraisal and inspections.
Hope that helps some.
