I've been looking into these things. It is likely a foreclosed multi-unit property being sold at $460 per unit. Foreclosures often have to be sold at whatever price the previous owner owed on the house.
Problem with these is they get purchased real quick by investors and such (not to mention the cleaning and repairs that are necessary). Basically it's never going to be move-in condition at that price. Depending on the area, you may want to knock it down and build something else or just sell the land.
Of course, there is the one in a million chance that you could buy a clean, livable 12 room house with cash.
Check it out in person.
