The Court of Appeals decision in Koble Investments v. Marquardt has materially shifted the risk framework for owning residential rental property in Wisconsin. Under the current interpretation, if a residential lease contains one of the prohibited provisions under Wis. Stat. § 704.44, the lease can be deemed void and unenforceable, even where the tenant suffered no actual financial harm. The remedy being pursued in active litigation includes refund of rent paid, potentially doubled, plus attorney fees.
