Singer and songwriter Billy Joel has done fairly well for himself over a career spanning almost 50 years in the music industry. But maybe things aren't going as well as they seem for Mr. Joel – unless he has another reason for selling his palatial Miami estate for just under $15 million. There's no word yet on exactly why Joel is deciding to move out – maybe it was an altercation with his neighbors Cher or Lil Wayne? Anyway, Joel bought the house back in 2006 for $13.5 million, so at least he isn't taking a loss. Here are some pictures of the 8,881 square-foot mansion, right on the ocean. Maybe you want to put in a bid?
