A couple things.
The most siginicant buyer's expense in our area is the cost of the loan. The other is the buyer's share of the escrow fee. Generally, a homebuyer will pay approx 2-3% of the home's price in these and other fees.
One other thing - the property to which your question was attached is in the foreclosure process and you may have noticed that it stated a "Notice of Default" had been filed. This "Notice of Default" is the begining stage of a process which will take up to about 4 months after which it can take another 1-2 months before the bank will put the house up for sale.
Finally, the loan amount associated with the default is unrelated to the price the bank will eventually sell it for. The bank will investigate the home's market value during the foreclosure processs and attempt to maximise the sale price.
As an example, a home could have two loans one for $830,000 (the first mortgage) and one for $230,000 (the second) - a notice of default might be filed on both loans. The value of the home in such an instance could easily be $700,000 - $800,000.
