Former Georgia resident here, look up the laws on the state website. It gives the timeline and what happens each step of the way. Georgia doesn't give a lot of leeway to homeowners, and it is a fast foreclosure state compared to someplace like Nevada or California. In our old subdivision, several homes went into foreclosure and I remember the Sheriff will always come to post a notice on the door giving the specific lockout date. I want to say it is something like 10 days (?) from the date the eviction notice is served. At any rate, once it is "sold" on the courthouse steps, which almost none actually do, it will then revert to bank ownership, and I'm pretty sure that at that point she needs to be completely moved out. If she already has the notice of the date of sale, and it's posted in the newspaper, which by law in Georgia they have to do, I sure wouldn't count on having that extra 4 days.
