Oscar-winning actor and real-estate mogul Nicolas Cage, who owns houses all over the U.S., clearly is interested in more than just a honeymoon in Vegas, given that he recently increased his real-estate holdings in Las Vegas by paying $8.5 million for a 14,306-square-foot, custom-designed mansion in the same subdivision where he paid $2.25 million a year earlier for a five-bedroom house.

In a Big Time Listings exclusive, we can report that Cage, 43, bought the seven-bedroom mansion in Las Vegas through his Hancock Park Real Estate Trust. The mansion has a commercial elevator to all three floors, a game room, a workout room, three fireplaces, Crema Marfil slab marble floors, a great room with surround sound, a gourmet kitchen with professional appliances and a 16-car garage, according to listing information. Built in 2003, Cage’s new mansion had been listed for $9.95 million.

The mansion that Cage just bought is in the same neighborhood where he also purchased a 6,842-square-foot house in late 2005 for $2.25 million, also through his Hancock Park Real Estate Trust, according to public records. That nine-room house was built in 1994 and had been listed for $2,595,000. Features in that house include a large yard (public records show it sits on a 0.43-acre lot), a pool, a spa, four full baths, one half bath, a patio and a balcony, according to public records and listing information.

It’s unclear whether Cage bought either house for investment purposes, for family members or for himself. The Las Vegas Review-Journal reported on Cage’s housing search in July 2005—when he was seen looking at a onetime mob-owned residence on the No. 1 hole at Las Vegas National Golf Club. However, the paper has never grasped that Cage actually now has closed on two different properties in Las Vegas. Also in October 2006, the paper referenced “speculation that he might be moving here.” Plus, Cage has had business reasons to be in Vegas at least temporarily, given that he filmed his upcoming movie “Next” in Las Vegas in July 2006.

However, we believe that the Las Vegas news media have missed Cage buying those two properties over the last year-plus because Cage bought the properties through his trust.

Cage has far too many other houses around the country to list here right now, including multiple properties in Los Angeles, a place in New York, at least one residence in New Orleans, and at least one place in San Francisco, according to public records.
