Fond du Lac County, WI tax sales

County offices

County notes

• •Fond du Lac County forecloses delinquent parcels through the In Rem process, takes title itself, and then resells by sealed bid under Wis. Stat. 75.69. Investors buy county-owned land, never a tax lien certificate.
• •Minimum bids are set by the Finance, Personnel and Economic Development Committee before the notice of sale is published, and a bid under that figure must be rejected.
• •Earnest money of at least 10 percent of the bid must accompany the bid form as a certified check, cashier's check, money order or cash payable to the Fond du Lac County Treasurer. A personal check nullifies the bid.
• •A winning bidder is notified in writing and must pay the balance plus a $30 recording fee within 30 days of the date on that notice, or the acceptance is void unless the committee grants an extension. Earnest money from a winning bid is non-refundable.
• •Unsuccessful bidders get their earnest money back within 45 days of the public bid opening, with no interest.
• •The county conveys by quit claim deed and furnishes no title insurance. The foreclosure judgment wipes out prior-year taxes, special assessments and special charges, but the buyer owes the current-year taxes.
• •Property sells as is, where is and with all faults. The county makes no representation on zoning, access, boundaries, wetlands, floodplain, soil, water supply or utilities, will not clean up wells, septic systems or environmental hazards, and does not guarantee access to inspect. Contact the city, village or town about permitted use before bidding.
• •Parcels are usually small urban lots rather than acreage. The 2025 offerings were three vacant City of Ripon lots at minimum bids of $5,000 to $15,000 and a vacant downtown Ripon commercial building at a $22,700 minimum bid, and the county published its own inspection report for that building.
• •Sheriff's sales listed elsewhere on the Treasurer's site are mortgage foreclosures, a separate process from these tax foreclosure sales.

Wisconsin rules

Redemption

The redemption right in Wisconsin runs against the county, and it is over before an investor sees the parcel. Issuance of the tax certificate on September 1 starts the clock. Two years later the county may take its deed or start a foreclosure, but the right to redeem does not end on that anniversary: under s. 75.01(1)(b) any person may redeem at any time before the tax deed is presented to the register of deeds and accepted for record, and a redemption before recording makes the deed void as to the land redeemed. On the in rem route under s. 75.521 the county publishes a notice fixing the last day for redemption at least 8 weeks after first publication, and an interested party may instead serve a verified answer within 30 days after that date on the three grounds the section allows. Once the deed is recorded or judgment is entered, redemption is finished. Between the two, at least 6 and not more than 10 months before the redemption period expires, the county treasurer must publish a class 2 notice listing every unredeemed parcel with its amount due and the last day of redemption, which is the public list an investor can watch. Two things can still pull a parcel off a sale list afterward: the minor and incompetency extension in s. 75.03, and the former owner repurchase right in s. 75.35(3).Wisconsin Statutes 75.01 - RedemptionWis.

Deed deposit

Wisconsin fixes no statutory deposit. Section 75.35(2)(am) lets the county board sell its tax-deeded lands in whatever manner and on whatever terms it sets by ordinance or resolution, and s. 75.35(2)(d) lets the board delegate that power to a committee, an officer or a department, or hire licensed real estate brokers on commission. Deposits are county rules, not state law. St. Croix County requires a 10 percent deposit by cashier's check or money order with each sealed bid and rejects personal checks. Counties selling through the statewide online auctioneer instead take payment by certified check or wire transfer under the platform's terms.

Homestead deeds

Owner-occupied homes are treated differently, and the difference can pull a parcel off the list. For single-family, owner-occupied properties the county board must by ordinance give the former owner who lost title, or that person's heirs or beneficiaries, the right to buy the land back before it is sold, on paying the costs and expenses under s. 75.36(3)(a), the property taxes that would have been owed for the year of the purchase, and enough to satisfy any other liens at the time of foreclosure plus the county's repurchase costs. The board may extend the same right to other property types at its option. A sale under that ordinance is exempt from s. 75.69 altogether, so it never reaches a public bid. Counties set their own window. Dane County gives the former owner 60 days from delivery of the treasurer's certified-mail notice. Treat an owner-occupied house on a Wisconsin land sale list as provisional until the repurchase window has closed.Wisconsin Statutes 75.35 - Sale of tax-deeded lands; purchase of adjacent landsWis.

Surplus proceeds

Wisconsin returns the surplus to the former owner, and the county treasurer has to go find them. On taking the tax deed the treasurer must notify the former owner by registered or certified mail, at the mailing address on the tax bill, that the former owner may be entitled to a share of the proceeds of a future sale. When the county sells, the treasurer computes net proceeds by subtracting foreclosure, record-keeping, legal, advertising and title insurance costs, the actual maintenance, board-up, clean-up and demolition costs reasonably needed to sell, real estate agent or broker fees, and all unpaid general property taxes, interest, penalties, special assessments, special charges and special taxes. From the net proceeds the treasurer pays any managed forest withdrawal tax and fee, then the taxing jurisdictions' special assessments and special charges, prorated if the money runs short. Anything still remaining goes to the former owner, less any delinquent taxes, interest and penalties that person owes the county on other property. A payment unclaimed one year after mailing becomes unclaimed funds under s. 59.66(2), and no interest is paid on any of it.Wisconsin Statutes 75.36 - County acquisition and sale of property (net proceeds and the former owner's share)Wis.

A tax deed does not convey marketable title. Most buyers file a quiet title action before they can resell or insure the property. See the due diligence guide.
