Platform

ILTaxSale / Joseph E. Meyer — Rock Island tax deed sealed bid (+ Treasurer annual sale) ↗

Deposit rules

Sealed-bid tax-deed track: submit bid ≥ minimum with full payment by certified funds or personal check by deadline (see catalog terms; sample sealed-bid PDF on iltaxsale.com). No live outcry. Deed transfer ~90 days after paid in full if no timely title-defect rescission. Annual lien sale: register with Treasurer and pay awarded taxes+costs per packet.

Title risk

Liens that survive the sale

Certificate path: lien only until tax deed. Trustee/tax-deed sales convey after forfeiture pipeline but federal liens and some interests can survive; Meyer terms disclaim lien warranties — buyer must title-search (30-day defect rescission window typical on sealed-bid contracts).

Quiet title

Tax deed petition/notice is required after redemption; quiet title still common for insurable title on Illinois tax-deeded parcels.
