The Mediterranean-Style Mini-Palace, which boasts 8,881 square feet, is located on La Gorce Island, an exclusive neighborhood where stars like Cher, Lil Wayne, Ricky Martin and Shakira have lived.
La Gorce neighbors Lil Wayne and Ricky Martin also recently put their homes there on the market. 
Joel reportedly bought the Miami Beach house for $13.6 million in 2006.
Sources close to the deal tell us, the sale went through Friday for just under $14 million.  The 7-bedroom, 8.5-bath waterfront super house has been on the market since May 2012, when Billy listed the home for $14.75 million.

And the mystery buyer -- a guy named Diego Della Valle ... owner of Tod's shoes and majority shareholder in Saks Fifth Avenue. He's worth a reported $1.55 BILLION ... nearly ten times what Billy's reportedly worth ($160 million).
