The property is in the process of being foreclosed on which means the owners still have a say in whether or not they sell at the price stated. Once the property is forclosed on and the bank owns it the bank will have a price valuation done and will put it on the market at what is determined to be market value (most likely higher than 69,000.) If the owner chooses to sell the property for what they owe on it the bank isn't involved, if they try to sell it for less than they owe they either need to bring cash to the closing table or it becomes a short sale which is a completely different set of rules.
From what I can gather on this property you need to register with the link and get the remaining information before you will know which situation you are dealing with.
I'll be glad to help track down the information if you want to pursue this particular property or other foreclosures in the area.
