Notes

Wisconsin tax-deed county (Oshkosh / Neenah–Menasha metro). County uses in-rem tax foreclosure under Wis. Stat. ch. 75 then resells tax-foreclosed land — no investor lien certificates. Resale channel is typically Treasurer-managed (online surplus platforms, sealed bid, or direct sale when inventory exists). Confirm current listings with Winnebago County Treasurer; do not confuse with mortgage sheriff sales.

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.
