Does anyone know what happens if a house doesn't sell at a Sheriff's sale?

Answer 1

You are presuming that there will be no bidders at the sale. The party forcing the sale can make a "credit bid", meaning they can bid the debt instead of bidding cash. If there are no other bidders, the property would revert to the lender or the judgment creditor.

Answer 2

It will go back to the lender and they will try to sell it privately. If it sells for less than is owed. They will look to the former owner to pay the difference
