Lenders approve short sales without people being behind on their mortgage a lot more often than people think, you should talk to a few different agents who specialize in short sales. If they'd go for a short sale I'm sure they might be interested in sticking you with the difference as an unsecured personal loan as well. It's either that or renting the home out, and covering the difference, if you can manage, but if it's putting you at a loss then the short sale could be around the corner anyway.
