7. Jennifer Lopez’s Mansion – Los Angeles, California

On the Market Since: 2015 
Total Area: 17,129 square feet 
Initial Value: $17 million*

Jennifer Lopez’ palatial, gorgeous California mansion has everything that a pop star would ever want—including a dressing room to get ready for Hollywood events. The singer listed the 17,000-square-foot Hidden Hills mansion for $17 million in 2015. In addition to the dressing room, the home also has nine bedrooms, a dance studio, twenty-seat theater, gym, and a huge recording studio.

Despite all this luxury, Lopez had trouble selling the place. She had to drop the price down $4.5 million, listing it for $12.5 million. Lopez also has residences in New York, Miami, and Bel Air—but those, she’s planning to keep.

You might think that California, the home of mega-companies like Apple and the state known for being almost as expensive as New York, and its property taxes are why the home didn’t sell, but that isn’t likely the case. The property tax rate in Cali is lower than even Ohio’s. A median home in the state ($385,000 value) raises just $3,104 in taxes.
