George Bochetto, a Philadelphia lawyer who claimed to own the house with his late partner’s widow, bought it in 2016 for $60,000.
“It has been abandoned for many years. It was run down,” Mr. Bochetto said in an interview Tuesday. He marveled at how “this little house on the western edge of Louisville, modest as it was, could produce a magnificent world figure.”
He added: “Muhammad Ali was one of my heroes as a child.”
Mr. Bochetto said he wants the new owners to “make sure the house is preserved” as an honor to him.
The sale would also include the contents of the house, he said.
“My goal now is to sell this property to an institution or an individual or group of individuals who will be dedicated to preserving and promoting the property as a national historic site and monument,” he said.
