You could try to play hardball and re-negotiate the lease. It wouldn’t be nice but, hey, business is business, right?

The landland needs you more that you need her right now. She probably can’t afford for the place to go vacant for a few months.

September is not too far off. If I were you, I’d renew the lease in September and ask for at least 1 1/2 months free rent and take my chances with a future foreclosure.
