After the foreclosure auction it is 10 days after that the high bidder or original lender will get a "certificate of title".
If the lender got the property back, it's possible they may offer you a $1,000 - $2,500 as an incentive to move out.
Now if an Investor bought it, they may file an eviction action at the courthouse and have the sherrif escort you out.
If you have a signed lease, you may be able to stay until your lease expires.
I'm not an attorney so you would need to talk to an attorney to verify everything.
All the best,
