This 13,000 square foot Mediterranean-style home in Palm Beach County was purchased by Billy Joel only a year ago for $11.836M. The home was built in 2004, and renovated recently. It's unclear if renovations occurred prior to or after Joel's purchase and if they caused the price hike. The home provides intracoastal views of both Lake Worth and the Atlantic ocean. It features seven bedrooms, with an additional two bedrooms in the guest house. The gorgeous interiors combine a rustic European charm with an open and relaxed island style. There are vaulted wooden ceilings, a sparkling pool, and private dock. And no, there is no piano prominently featured in the pictures.
