"The house is filled with little moments like that. Moments of being a family," he told the magazine. "I'm very happy to have saved this old family home from a near certain death or development."
According to The Associated Press, the six-bedroom, 2.5-story Colonial home last came under scrutiny in 2014, when its former owner was charged with animal cruelty. More than a dozen cats were seized from the home and the remains of several others were found.
The home left Kelly family hands in 1974, when it was sold and flipped in a few days to its most recent owner, according to People.
The house sold on Sept. 23 for $754,000, according to Philly.com.
Kelly made her name in Hollywood with films such as "Dial M for Murder," "Rear Window," "High Society" and "To Catch a Thief." Reports indicate that Prince Rainier III proposed to her in her childhood home. The couple married in 1956.
