The governing law
Iowa is a tax-lien state. On the third Monday in June every county treasurer offers each parcel with delinquent taxes at public sale, and the bidder who accepts the smallest percentage of undivided ownership in the parcel wins the certificate of purchase. The certificate earns 2 percent per month, a rate fixed by statute rather than bid down at the sale. If the parcel is not redeemed, the certificate holder waits one year and nine months from the sale date, serves a notice of expiration of the right of redemption, and can take a treasurer's deed 90 days after that service is complete. Chapter 446 governs the sale, Chapter 447 the redemption, and Chapter 448 the deed.
