How to buy tax-sale property in Iowa (2026)

Tax lienFlat rateBid down ownershipTax lien · 21 months from the sale redemption · once a year, typically in June

You buy a tax lien, not the house. The owner has 21 months from the sale to pay you back. You earn 2% interest a month. You win by bidding down the share of the property you will own. You get at least 90 days' notice before the sale. Sales are held once a year, typically in June.

Interest / penalty: 2% flat per month · Bid method: Bid down ownership

How Iowa tax sales work

Iowa uses tax lien sales in the state registry. The official rule describes the sale as follows: “The delinquent tax lien transfers with the tax sale certificate, whether held by the county or purchased by an individual, through assignment or direct purchase at the tax sale.” What the winning bidder receives, and the steps after the sale, depend on the county's published terms.

Auction format and timing

The registry records bid down ownership as the bid method and once a year, typically in June for the sale schedule. The statute or official rule linked below controls the auction date, location, notice, and bidding format. When the schedule is not documented statewide, verify the date with the county treasurer, tax collector, sheriff, or other selling authority.

Sources

Iowa holds an in-person annual tax lien sale on the third Monday in June (counties may designate another June date for good cause). Bidding is a bid-down: the purchaser is the one who will pay the total amount due for the smallest percentage interest. Iowa law permits but does not mandate a bidder registration fee, so registration requirements vary by county (Scott County, for example, requires online registration). Payment methods and timing are not specified in the cited sections.
