Rock (née Robert James Ritchie) bought the Point Dume property - which is described by the listing at CaliforniaMoves.com as a "Balinese oasis" - in October 2006 for $11.6 million.
The home has just over 8,000 square feet of space with an open floor plan and huge, stunning rooms. The master bedroom even has his-and-hers walk-in closets.
The five-bedroom mansion sits on 1.54 acres of property, with a pool in the backyard, as well as a mini guest house.
According to real estate blog Trulia, Rock still has plenty of homes left in his real estate portfolio. He also owns a 6,000-square-foot waterfront mansion in Detroit; an ocean front home Jupiter Inlet Colony, FL; a condo in Nashville, TN; and two adjoining estates northwest of Detroit.
