Head-to-head: 9 dimensions
Penalty repeats each 6mo (max 9%/period since 2022) but Cook bids near 0%; post-HB 4537 surplus rules reduce windfall upside
10-15% flat penalty on min bid inside 1yr; 5%/yr overbid drags blended yield
Full 6-month penalty tranche owed even if redeemed on day 1 of period
Flat 10% (redeemed ≤6mo) / 15% (6-12mo) of min bid regardless of day
3yr default (extended from 2.5yr via HB 4537, eff. Jul 2026); slower capital recycle but more predictable window
1yr from sale; 120 days at commissioners' certificate sales
County-by-county sales with registration/deposits; Cook uses R.A.M.S. sealed bids
Many counties run fall sales online via SRI/Zeus Auction
Institutional buyers dominate; penalty bid to 0% on quality parcels
Premium bidding pushes overbids up in Marion/Lake; rural sales thinner
Individual liens can be small, but deposits and registration add friction
Min bids often a few hundred dollars of taxes plus costs
Strict take-notice/petition traps; sale-in-error can void the investment
IC 6-1.1-25-4.5/4.6 notices + court petition; defects forfeit the deed
HB 4537 (Jul 2026) rewrote key collection provisions; post-Tyler surplus rules still settling; new regime untested in court
IC 6-1.1-24/25 framework stable with periodic tweaks
Unsold/forfeited liens resold via county trustee lists
Commissioners' certificate sales resell leftovers at reduced min bids
