A tax deed sale is the sale of property for past due real estate taxes and fees associated with the sale. Each year, real estate taxes are to be paid by a predetermined date to avoid becoming delinquent. Once delinquent, the Tax Collector holds an auction to pay off the taxes. This auction is referred to as a Tax Certificate Sale (FS 197.432).
The successful bidder at this auction is issued a Tax Lien Certificate, which ensures the bidder that the Tax Lien will be paid off, with interest.
