you dont have to pay the rent to the owner now. They can not do much about it. At the worst, they (either the current owner, banker, or future owner) will tell you to move out, then you should have 90 days (living free for now rent although you may be bothered a lot) to do it.

for auction sale, each state might be different. Usuallyit it is done at the front of the county court house. Note, not in the court house. This info is not easy to get (either from newspaper or courthouse notice). several webpages (like realtytrac.com) might have this info but they charge for the service.
