What a tax lien certificate is, in one paragraph

A tax lien certificate is the county's claim for unpaid property tax, sold to an investor at a public sale. The investor pays the tax, the owner owes the investor that amount plus a rate set by state law (Florida 18% a year, Arizona 16%, Iowa 24% fixed, Illinois up to 18% per six-month period, Texas 25% flat on a redeemable deed), and if the owner does not redeem within the state's period, usually one to four years, the investor can apply for the deed or foreclose. About half the states sell liens; the rest sell the deed outright and the return is the discount to market value. TaxLienSimple tracks 299,674 parcels across 825 counties, 410 scheduled county sales with dates read from the county's own notice, and the county-held certificates that can be bought today without an auction, every one linked to the statute and the county source it came from.
