Have they been served the 3 day notice to quit yet?
If not, they have at least 3 days.
If they have and have gone past 3 days they’ll be eviction proceedings and all that.
It really depends where they are in the process.
The home didn’t get sold with no notice btw, they would have had a NTS filed and the lender was postponing. Then once they missed the loan mod payment (!) the lender took the next sale date and foreclosed. The lenders give people a LOT of chances.. your friend just used them all up.
