Location of Miami's most expensive house sale ever (the $47 million 3 Indian Creek Drive) the Whales of Indian Creek Island include Julio Iglesias, Norman Braman, and the anonymous purchaser of said record breaking house.

Sure, Whales swarm South Beach, but a few particular residential towers (well, more than a few) seem to keep breaking sales records. One of these is the Setai, where a full-floor penthouse just went for the grand sales price of $27 million.

North Bay Road has been hot with the whales lately, like A-Rod who just built a huge contemporary house there, and heir Wayne Boich Jr. who's building an even bigger contemporary place with a moat.

Star Island, even more than neighboring Islands Palm and Hibiscus, has been getting ever more popular with the whales lately. A Real Housewife of Miami wants to tear down an historic estate, and we hear some very very wealthy Russians have moved in.
