How Milwaukee County sells delinquent taxes
No tax lien certificate sale
Wisconsin counties sell no tax lien certificates to investors. Under s. 74.57(1) the county treasurer issues the tax certificate to the county itself, and s. 74.57(3) states that the county may not sell, assign, or otherwise transfer it. The section carries two carve-outs, and neither admits a bidder: a county may sell its right to receive tax certificate revenues under s. 74.635, which is a payment stream rather than a lien, and the county treasurer must reissue certificates to a city acting under s. 74.87 that has paid the delinquent taxes under an agreement made under s. 74.83.

When it runs
Registration and deposit
Bidding runs through a sealed Invitation to Bid, not a live auction. Pull the ITB packet from the property's MLS listing through a licensed real estate agent or from the Bids and RFPs section of the county Economic Development site, then submit on the county's Bonfire procurement portal, which asks for a free Euna Supplier Network account to download documents and upload a submission. A complete bid carries the signed Bid Document, a signed Buyer Affidavit, a signed WB-11 Offer to Purchase, a Buyer Intent Form, and either a lender pre-approval letter or proof of funds for a cash offer. Buyers must meet the Economic Development Buyer's Criteria, meaning no delinquent taxes and no unresolved code violations anywhere in Milwaukee County. Late or incomplete submissions are not considered, and the county notifies every bidder within one week of the deadline.

Check the state rules that change the bid
Read the Wisconsin due-diligence checklist before bidding. Redemption, liens that survive a tax deed, title cleanup, and payment deadlines can change what a parcel is worth. Which liens survive is state law, so read what survives a tax deed in Wisconsin before you price the title work.Set a walk-away number
Work out what the parcel is actually worth with the rural land value estimator, then turn it into a ceiling with the tax deed max-bid calculator.
Over-the-counter (leftover) purchases
unsold properties
Wisconsin has no statewide over-the-counter program at a fixed statutory price, and no state-held certificate to assign. County inventory is what stays for sale. The county board may sell its tax-deeded lands on whatever terms it sets, may hire licensed real estate brokers on commission, and may advertise on a multiple listing service, so a county parcel can sit on the open market between sales. Once a parcel has been advertised and not sold, the county may sell it for any amount after a further class 1 notice, subject to board or committee approval below the appraised value. Ask the county treasurer or the land committee for the current list of unsold county-owned parcels and make a written offer. Approval still runs through the board or its committee, so nothing closes on the day.

County notes
- Emily Streff is the Economic Development project manager who handles tax-foreclosed properties, reachable at 414-897-2384 or [email protected].
- The Milwaukee County Treasurer, 901 N. 9th St., Room 102, Milwaukee, WI 53233, 414-278-4033, runs the delinquent tax collection and in rem foreclosure side for 18 of the county's 19 suburban municipalities. The City of Milwaukee Treasurer collects its own city taxes and forecloses its own parcels.
- Inventory is small and suburban, with listings in communities such as Cudahy and West Allis rather than the City of Milwaukee.
- Showings require a licensed real estate agent, who requests access and receives the lockbox code.
- Offers are scored on financial readiness, compliance with the ITB requirements, and community impact, with stated preference for owner-occupancy and neighborhood revitalization.
- An accepted offer still needs Certification by designated county officials before the quit-claim deed issues.
- Milwaukee County Sheriff real estate auctions run every Monday morning and cover lender mortgage foreclosures, mostly inside the City of Milwaukee. Check for delinquent taxes before bidding on one; details at 414-278-3073.
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).
- 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. Read the county's own bid packet before you bid.
- 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.
- 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.
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.
