When Gustorf died in 1940, the house was sold to numerous owners before being bought by its next long-term tenants, Mr. and Mrs. Samuel Burns, in 1950. They lived in the house for the next 35 years, when in 1985 it was sold to William Kortsch. Kortsch loved the house and restored it to its former glory after years of dilapidation but retaining its original floors and paneling. As living in the 550-square foot home would not fit for Kortsch's family of six children, they lived next door and leased the home to several tenants, including local musician Paul Finger.
In 2017, the 90-year-old Kortsch decided to sell the boat house, and passed away soon after. The buyers were actually dental patients of his- Nola Hitchcock Cross and her husband Steve, who live down the street. They turned the beloved Milwaukee historic landmark into an Airbnb, so even more people can experience this work of exotic architectural fantasy.1
