Landlords try to evict you when you don't pay rent...and you can screw them, and stay as long as you like. The courts practically protect you in that manner.
So, since your deposit may be kept until a judge gives it to you (and you still won't get it, if they're jerks), stay. Don't leave. Screw them, for a change. See how much the new owners are willing to pay to get you out on time.
OK, so maybe it's just the beer talkin'...but I'm willing to bet you could be a hardnose, and come out ahead...or at least, better off than before.
