The funniest part about it is that he's so retardedly ignorant about what is actually happening to his parents' property.
A short sale (something I looked into because I might have bought a short sale) is when you sell your house for less than the balance of the mortgage because you can't afford to keep it. The banks basically say, "OK, we have a contract that says that you're going to owe us this, and we took a risk in giving you a loan. Now you're asking if you can pay back the loan later, with less collateral, because you can't afford to make the payments that you currently owe."
The banks are actually helping this guy's family out and he's just screaming like an idiot.
