Notes

Illinois tax-lien certificate county. Adams County Treasurer (Quincy) holds the annual tax sale of delinquent real estate taxes under the Property Tax Code — interest-rate bid-down certificate sale, not a deed. Treasurer 507 Vermont St Ste G12, Quincy; 217-277-2245. Peer western Illinois pattern is late-year annual sale after final collections (final tax distribution historically mid-November after the sale). After sale, call Adams County Clerk 217-277-2162 for redemption amounts. Certificate of purchase is not ownership; tax deed requires later judicial process after redemption expires (2–3 years class by property type). Quincy / Mississippi River / I-172 market.

Platform

Deposit rules

Register with the Treasurer before the sale per office instructions (217-277-2245). Illinois certificate sales require payment of taxes purchased plus penalties as bid; bring certified funds capacity as directed. Confirm collateral/registration fee in writing before sale day. Certificate is not ownership.

Title risk

Liens that survive the sale

Buyer receives a certificate of purchase, not the property. Owner redemption extinguishes the claim. Surviving-lien analysis mainly matters after a tax deed is pursued through the judicial process post-redemption.

Quiet title

Obtaining a tax deed requires a judicial petition/notice process after redemption expires — that process functions like quiet title and is a required court step, not optional.
