Illinois vs Arizona
Same underlying data as the individual state pages, side by side. Statutory rates and redemption windows only — always confirm against the county's own auction notice before bidding.
| | Illinois | Arizona |
|---|---|---|
| Sale type | Tax lien certificate | Tax lien certificate |
| Rate / penalty | Up to 9% per 6-month period, bid down | Up to 16%, bid down |
| Redemption | 2.5–3 years (1 year for vacant/commercial) | 3+ years |
Both states run the same kind of sale — tax lien certificate — so the real difference between them comes down to rate and redemption, not the underlying mechanism.
Redemption windows differ: Illinois gives owners 2.5–3 years (1 year for vacant/commercial), Arizona gives 3+ years — the state with the shorter window resolves faster, for better or worse depending on what you're optimizing for.
Illinois sells delinquent taxes at an annual county tax sale where bidders compete on the penalty they will accept, capped at 9% since 2022 (35 ILCS 200/21-215); the redeeming owner pays that penalty once for each six-month period that has begun, up to six (§ 21-355). Most property can be redeemed for 2½ years (one year for vacant non-farm, commercial, industrial and 7+-unit property), and three years on certificates sold on or after July 10, 2026, when HB 4537 (P.A. 104-553) replaced the direct tax deed with a court-ordered auction that returns any surplus to the former owner and let counties acquire the liens themselves (§§ 21-190, 21-350, 22-40, 22-42).
Full Illinois page →Arizona tax lien certificates carry a maximum of 16% simple interest (A.R.S. § 42-18053), auctioned by bid-down like Florida (§ 42-18114). The holder cannot sue to foreclose until three years after the sale and must do so within ten (§ 42-18201), and the owner can redeem until the treasurer's deed is delivered (§ 42-18152).

| | Illinois | Arizona |
|---|---|---|
| Median home value | $263,300 | $394,500 |
| Median property tax / year | $5,298 | $1,879 |
| Tax / home value | 2.0% | 0.5% |
| Tax / household income | 6.4% | 2.3% |
| Homes owned outright | 39.2% | 38.2% |
| “Other vacant” homes | 3.9% | 2.2% |
| Median year built | 1971 | 1992 |
A typical home in Illinois pays 2.8× the property tax of one in Arizona ($5,298 against $1,879 a year). One unpaid year is roughly the face value of a one-year certificate, so a typical Illinois lien ties up about 2.8× the money of an Arizona one — and, at the same rate, earns 2.8× the dollars.
Homes owned outright — where no lender has a reason to pay the delinquent bill for the owner — are 39.2% of owner-occupied homes in Illinois and 38.2% in Arizona. The Census “other vacant” share (foreclosures, homes in legal limbo or needing repairs, abandoned homes) is 3.9% against 2.2%: Illinois has more of the empty properties that tend to go unredeemed — and to need work if the deed ends up yours.
