This "listing" is simply a home that is in default, but not for sale, and may never be for sale.
Realty Trac compliles data - lists of homes in which paperwork has been filed and the owners are in arrears, have mossed pay,ents, etc - the number shown is NOT a list price. It is the amount currently owed on the property.
Don't get your hopes up on homes you see with Realty Trac.
And........... do not pay them for their lists. You will be throwing your money out.
Once a home is foreclosed on, and really for sale, it will be listed with an agent.
