The 46-year-old actor and Taylor are hoping to sell their lavish Manhattan duplex, which has already attracted interest from financial gurus with families looking for a laid-back luxury lifestyle, reported New York Post online.
But the couple are prepared to make a loss on the property after paying USD 10 million for it four years ago.
"They love real estate and enjoy moving every now and then," a source said.
The house boasts of modern interiors, five bedrooms, five bathrooms, a huge living room and a media screening room where Ben, Christine and their 10-year-old daughter Ella and seven-year-old son Quinlan used to enjoy watching movies together.
There is a room for staff with a maid's quarters, a laundry room and a separate service entrance, while the two children's bedrooms in the house have been beautifully decorated.
