The family purchased a lakefront property in a nice area three years ago but then ran into a series of issues, and have abandoned the place because of them.They are hoping the bank allows a short sale (asking for roughly $20,000 under what is owed)Here's what's made them so unhappy:Anytime they used the laundry it was dumping into a dry well, which would back up into the house forcing them to take their laundry to a laundromat instead!!

Are they way under market, or is it manageable for now?
