Certificate of Sale
A document indicating that a property has been sold to a buyer at foreclosure, subject to a right of redemption for a set period after the foreclosure sale. In an IRS, the redemption period is 180 days. The redemption period is different in other types of foreclosure. Many foreclosures take place without any certificate sale. Instead, if the sale is final, or near final, the buyer gets a deed rather than a certificate of sale.
