Wisconsin tax sale investing: buy the property itself at the county sale

Quick answerWisconsin sells tax deeds for unpaid property taxes. Redemption: The owner may redeem at any time before the county records a tax deed or an in-rem foreclosure judgment bars the right. A county generally may take a tax deed or foreclose its certificate after 2 years from issuance of the tax certificate (1 year where razing/restoration costs are included, or for certificates held by a city acting under Wis. Stat. 74.87 or a county of 500,000+ population in an in-rem action) - Wis. Stat. 75.14, 75.19, 75.521. No redemption after the county takes title and sells. Sales: No single annual sale date; counties take tax deeds / in-rem judgments on a rolling basis and sell tax-deeded land year-round as inventory is cleared, after advertising under Wis. Stat. 75.69. Governing law: Wisconsin Statutes ch. 74 (esp. 74.47, interest and penalty) and ch. 75, Land Sold for Taxes (esp. 75.14, 75.19, 75.35, 75.521, 75.69).

How it works in Wisconsin

In Wisconsin the county sells the property itself at a tax deed auction. Win the bid and the deed is yours — along with the due diligence burden, because sales are as-is and buyer beware.

Interest / penalty: n/a - Wisconsin sells no tax lien certificates to private investors; the county itself holds the tax certificate. Delinquent amounts bear interest of 1% per month plus an optional county penalty of up to 0.5% per month under Wis. Stat. 74.47, retained by the county, not paid to a buyer.

Redemption: The owner may redeem at any time before the county records a tax deed or an in-rem foreclosure judgment bars the right. A county generally may take a tax deed or foreclose its certificate after 2 years from issuance of the tax certificate (1 year where razing/restoration costs are included, or for certificates held by a city acting under Wis. Stat. 74.87 or a county of 500,000+ population in an in-rem action) - Wis. Stat. 75.14, 75.19, 75.521. No redemption after the county takes title and sells.

When sales happen: No single annual sale date; counties take tax deeds / in-rem judgments on a rolling basis and sell tax-deeded land year-round as inventory is cleared, after advertising under Wis. Stat. 75.69.

Where sales run: Wisconsin Surplus Online Auction is used by many counties for tax-deeded land; other counties sell through their clerk/treasurer by open or sealed bid, GovDeals-type surplus channels, or licensed brokers under Wis. Stat. 75.35 and 75.69. County-specific.

Governing law: Wisconsin Statutes ch. 74 (esp. 74.47, interest and penalty) and ch. 75, Land Sold for Taxes (esp. 75.14, 75.19, 75.35, 75.521, 75.69)

The investor's edge

Your edge is the max bid: value the property from county records and recent sales, subtract title-clearing and repair reality, and write the number down before the auction opens.

Because the county is always the certificate holder, investors can only buy real property after the county has taken a tax deed or in-rem judgment - there is no certificate market. Counties may give a purchase preference to the former owner/heirs and must follow the surplus / former-owner notice rules enacted in recent sessions.
