Notes
Wisconsin tax-deed county (Janesville–Beloit). Rock County follows statewide in-rem tax foreclosure then county resale of tax-deeded parcels — no lien certificates. Disposition is Treasurer-managed (sealed bid, listing, or online surplus when inventory exists). Confirm current land-for-sale status with Rock County Treasurer; separate from mortgage foreclosure 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.
