Legal Question in Landlord & Tenant Law in California

First off, is it has been through foreclosure, then she couldn't be doing a short sale. So you clearly don't even know what the actual situation is. Second, as long as she owns the house, you owe her rent. Period. If she sells or loses the house, you will owe the new owner rent and will probably have to move within anywhere from 30-90 days after the change of ownership, unless you have a lease that will not run out until longer than that.
