Notes

Wisconsin in-rem tax foreclosure county. Columbia County Treasurer (Portage) sells tax-delinquent foreclosure properties by blind sealed bid after foreclosure, not a live courthouse outcry. Notices publish in the Portage Daily Register and on the county Land Sales page. Minimum bid equals appraised value; county may accept or reject any bid; bidders currently owing Columbia delinquent taxes are disqualified. Quitclaim deed after full payment. Distinct from weekly Sheriff mortgage foreclosure sales at the courthouse (Ch. 846) — those are not the tax-foreclosure land-sale track. Madison–Portage I-39/90/94 corridor market (Portage, Lodi, Poynette, Columbus).

Deposit rules

Submit a County Bid form in a sealed envelope marked "Land Sale Bid" with parcel number on the exterior, delivered to the Treasurer on or before the Notice of Sale deadline. Bid must meet at least the published minimum (appraisal). Earnest money: certified check, cashier's check, money order, or cash equal to 10% of the bid, accompanying the bid. Balance due within 30 days of the County's Notice of Acceptance or earnest money is forfeited. Rejected-bid earnest money returned within 15 days of bid opening.

Title risk

Liens that survive the sale

County in-rem foreclosure is intended to convey title free of most prior private liens, subject to federal tax liens and sale-specific exceptions. Special assessments and municipal charges can require separate analysis. Quitclaim from the county is not a warranty deed — full title search mandatory.

Quiet title

Judgment of foreclosure is the primary clearing step; quiet title or extended review is still common when insurers want residual comfort on occupied or chain-of-title-complex parcels.

Wis. Stat. § 70.32(1) requires real property to be valued at the full value which could ordinarily be obtained at private sale, and § 70.05(5)(b) requires each taxation district to assess at full value at least once in every 5-year period. The Department of Revenue computes the actual assessed-to-full-value ratio for every district annually under § 70.05(5)(c) and notifies districts that drift more than 10% off over four years.
