The listing agent -- who is regularly featured on "Extra," "NBC Open House," "Mansions and Millionaires" and HGTV's "Million-Dollar Room," and who is a top real estate agent in Los Angeles with worldwide listings -- said he has rarely encountered an owner who put more meticulous care into building a luxury home.

 

Each estate has a 25-foot shooting range. "Lucy Liu used the shooting range to practice for her role in 'Southland,' " the broker said.

Abbey is an avid outdoorsman. The Bradbury estate has a million-gallon trout pond. "It's larger than the Aquarium of the Pacific (in Long Beach, CA) and it cost $8 million to build," Abbey's listing agent said.
