What options do have when your landlord gets the home your renting in foreclosure

Your lease is valid and permits you to remain there.  You must continue to pay the rent to the owner of the property until the propery is sold at sheriff sale, if that actually happens.  If that does happen, the new owner (perhaps the bank) will contact you about next steps. There won't be any midnight move out situations for you but if you're near the end of your lease term, you should plan to move so that you don't have to deal with the uncertainty.
