You may pay with cash, or you will be given enough time to go to your local bank or lending agency and get a cashier's check for the full amount of your bid.
You must pay the full amount to the Sheriff's Office by 4 p.m. on the day of the sale.
You should have all paperwork finalized with your lending agency before you arrive at the sale. (You can call the lending agency from the Sheriff's Office to have it ready when you arrive.)
