MIAMI: Got a spare $17 million knocking about? NBA star Lebron James has put his waterfront Miami mansion - complete with sommelier’s wine cellar and custom theater - up for sale, just months after confirming his decision to return to the Cleveland Cavaliers. The palatial spread in the exclusive Coconut Grove neighborhood, billed by realtors as the “most opulent estate in Miami,” was bought by the basketball superstar for a cool $9 million in 2010. However, with James calling time on four glory-laden years with the Miami Heat in July, the mansion is now up for sale - at nearly double the price.  The listing from Opulence International Realty said the property also includes a chef’s kitchen, office, generator, guest home and private sun deck. The property includes six bedrooms, eight bathrooms and various swimming pools. James, 29, won two NBA championships during his stint at the Heat. –AFP
