South Florida was just as shocked as the rest of the sporting world when LeBron James and Chris Bosh decided to join the Miami Heat in July, but a banner year for Miami sports has turned into a solid one for the higher-end real estate market, with Miami Heat’s Big Three — James, Bosh and Dwyane Wade — leading a year of high-profile purchases and sales by local athletes.
The Heat stars weren’t the only ones buying or selling high-end properties in South Florida — athletes from baseball, football and basketball have purchased some of the area’s biggest and most expensive homes in 2010, led by Chris Bosh:
1. Chris Bosh buys on North Bay Road for $12.5 million

The former Toronto Raptors star snapped up the home for $3.5 million less than the listing price. The seller was Glenna Norton, the developer of the property.
