The Culbertson family sold the house and its furnishings in 1899. Over the following decades, the passage of time and changes in ownership left their mark on the mansion. When the State of Indiana took ownership of the house in 1976, much of it would have been unrecognizable to the family. The state started exterior renovations in 1980, and shortly afterward, the staff and the Friends of Culbertson Mansion began work to restore the original interior.
