According to New York State Foreclosure Law, "In New York, foreclosure sales are made by public auction, usually at the county courthouse. The property is sold to the highest bidder and anyone, including the lender, may bid. The winning bidder typically has to pay 10 percent of the final bid at the sale and the remaining balance within 30 days. When the full amount is paid, the winning bidder takes ownership of the property. Borrowers have no right of redemption after the sale."
