Iowa vs Colorado
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.
| | Iowa | Colorado |
|---|---|---|
| Sale type | Tax lien certificate | Tax lien certificate |
| Rate / penalty | 24% flat (2%/month), no bid-down | Federal discount rate + 9%, bid down |
| Redemption | 1 year 9 months (+ 90-day notice) | 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: Iowa gives owners 1 year 9 months (+ 90-day notice), Colorado gives 3 years — the state with the shorter window resolves faster, for better or worse depending on what you're optimizing for.
Iowa fixes its tax lien interest at 2% per month (24% a year) under Iowa Code § 447.1, so the rate is never bid down; bidders compete on the smallest percentage of the parcel instead (§ 446.16). After one year and nine months the holder may serve notice, and the right to redeem ends ninety days after service is complete (§ 447.9, § 447.12).
