Billy Joel – $16.9 Million, Palm Beach

After his song Piano Man became a huge hit, Billy Joel became the “Piano Man.” With more than 150 million record sales around the world, he made a sweet, sweet fortune for himself. With all that money rolling in, Joel purchased multiple properties.

His Palm Beach mansion caught the eye of many when news broke about the purchase. Joel purchased the 13,000-square-foot house in 2014 for $11.8 million. It seems that the eight-bedroom eight-bathroom residence overlooking the coast was purchased as an investment property. We believe so because just one year later, after renovations, he listed the mansion for $19.5 million—a price tag that later dropped to $16.9 million.
