If a landowner doesn't pay thier property taxes, then the Treasurer's Office advertises the land for 3 weeks in the newspaper, along with a notice giving the time and place for the sale. People show up at the sale and sign up to become a purchaser. The names of all purchasers are mixed and random names are drawn in succession, beginning at 9 a.m. That purchaser can choose an available Parcel from the list of delinquent accounts. The purchaser pays the amount of the taxes due on the land, plus interest to the date of the sale, advertising fees, and a certificate fees. The county issues the purchaser a Certificate of Purchase, entitling the purchaser to a lien on the land. The county distributes the taxes paid by the purchaser to the taxing entities in the county. The landowner has 4 years from the date of the sale to pay the purchaser back his money, including all fees and 18% interest, or the purchaser may apply for a Tax Deed on the land.
There is a limit to one bidder per tax ID. This limits companies from showing up with dozens of bidders all operating under the same tax ID.
