Penalty repeats each 6mo (max 9%/period since 2022) but Cook bids near 0%; post-HB 4537 surplus rules reduce windfall upside
18% (1.5%/mo) on face; overbids earn 0% and dilute real returns
Full 6-month penalty tranche owed even if redeemed on day 1 of period
Interest accrues monthly, so day-1 redemption pays little; the 5% damages go to the county, not the buyer
3yr default (1yr vacant/commercial); new rules apply to certificates issued on or after Jul 10, 2026
2yr redemption before purchaser can pursue the deed
County-by-county sales with registration/deposits; Cook uses R.A.M.S. sealed bids
GovEase online premium-bid sales across most counties (Apr/Aug)
Institutional buyers dominate; penalty bid to 0% on quality parcels
18% flat rate plus easy online access draws funds; heavy overbidding
Individual liens can be small, but deposits and registration add friction
Liens sell at face tax amounts, often a few hundred dollars
Strict take-notice/petition traps; sale-in-error can void the investment
Tax titles voidable on notice defects; chancery process is strict
HB 4537 (Jul 2026) rewrote key collection provisions; post-Tyler surplus rules still settling; new regime untested in court
Decades-old 1.5%/mo + 2yr redemption scheme, little change
Unsold/forfeited liens resold via county trustee lists
State tax-forfeited land inventory purchasable outside auctions
