Foreclosure is an option. If it's your only option, it sucks, but it is a way to cut costs. Is it expensive in itself, given the damage it does to your credit rating? Well, yes, but that doesn't mean it's not there, or sometimes the best choice. Should you not have ended up in the position where that was the best choice? Well, yes, but if that's where you are, that's where you are.

It's important to separate the ideal fact that you shouldn't be in that position from the practical fact that it is indeed an option.
