The Maison de L'Amitie was purchased from Donald Trump in 2008. Lined with gold and diamond fixtures, Trump refurbished the property and sold it to Russian billionaire Dmitry Rybolovlev for $95 million in 2010. Not a bad profit. The property also has a 100-foot swimming pool surrounded by gardens and near 50 car garage.
