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.

Property Intelligence
Every parcel gets a Research Score, not just a listing
Open any published parcel and see an A–D Research Score built from lien-to-value, county competition, auction timing, ownership signals and data completeness — plus the pre-bid warnings the record actually supports. Nothing is guessed; missing fields are labeled “not yet available,” never invented.
Open Property Research →The map is the product
Every delinquent parcel, drawn on the map with its owner
Parcel outlines, owner of record, mailing address, acreage and county value come straight from each county's own GIS layer. Hover a parcel on the research map and the county record is there. Real screens, a real St. Louis County block, owner names masked here and shown to members.


One parcel, from the county's own layer
Every county page shows a verified parcel outlined on imagery with acreage and land use. Members open the county and see all of them.
