John W. Henry owns the Boston Red Sox, the Boston Globe, and the Liverpool Football Club. He also owns a spacious Florida mansion that's currently on the market.

According to recent reporting from Forbes, the "custom-made" home is now listed for $15 million, marking a $10 million price cut. After a successful start at his firm, J.W. Henry & Co., Henry purchased the Boston Red Sox for $380 million in 2002, followed by Liverpool FC for £300 million in 2010 - almost $400 million today.

The home was first put on the market with Senada Adzem of Douglas Elliman Real Estate in November for $25 million after over two decades of use. Henry first purchased the property in 1991 for $650,000, and started using his completed mansion five years later.

The mansion now numbers as one of many major price drops over the past year, including a 70% discount on Michael Jackson's infamous Neverland Ranch and a billion-dollar mountaintop property now listed for $650 million.
