LOUISVILLE, Ky. — A big piece of Louisville history is up for sale: the house where boxing great Muhammad Ali spent his boyhood.

Owner Steve Stephenson said Monday he’s asking $50,000 for the small white house with a sagging front porch overhang. The house is situated along a tree-lined western Louisville neighborhood made up of mostly neat, modest homes.

A sign in front of the house says it is for sale by owner.

The house is assessed at $23,260, according to the Jefferson County Property Value Administrator’s website.

In front of the one-story home is a state historical marker recognizing the residence as Ali’s boyhood home, when he was known as Cassius Clay. The marker says Ali lived in the mostly black neighborhood with his parents and brother and attended local public schools.

It was at the home where the future boxing champion’s “values were instilled,” the marker says.

Louisville Mayor Greg Fischer said the city has an interest in preserving the home of a famous native son.

“Anything we can do to preserve and expand his legacy, we want to do that,” Fischer said Monday. “His home serves as an inspiration for people to look at that and say, ‘If this young guy, why not me?’ “

The three-time world heavyweight champion remains one of the most recognizable figures on the planet, even though his public appearances have become sporadic as he fights Parkinson’s disease.

Armstrong service set for Friday

CINCINNATI — A private service is planned in Cincinnati on Friday for astronaut Neil Armstrong, the first man to walk on the moon, and President Obama has ordered U.S. flags to be flown at half-staff.

The Ohio native died Saturday in Cincinnati at age 82.

Obama on Monday issued a proclamation calling for U.S. flags to be lowered the day of Armstrong’s burial, including at the White House, military posts and ships, U.S. embassies and other public buildings “as a mark of respect for the memory of Neil Armstrong.”

Ohio Gov. John Kasich on Monday ordered Ohio flags flown at half-staff through Friday.

U.S. Sen. Rob Portman, R-Ohio, will eulogize him at the service.
