Jeff Greene is a real estate and hedge-fund mogul who shorted subprime mortgage.
He purchased this property for $32,500,000 and spent several years renovating it with the help of real-estate developer Mohamed Hadid, architect Bob Ray Offenhauser, and designer Alberto Pinto.
Greene tried to sell the estate, named Palazzo di Amore (Italian for "palace of love") several times, and most recently, in March 2017, slashed the price to $129 million. Two years before that, the house cost $20 million more, and $66 million more than the original price, of $195 million, from 2014.
