Location: Melody Key, Monroe County, Florida
Purchased: Unknown
Current Value: $3 million*

Rocker Nick Hexum, the former lead singer of 311, owned Melody Key until 2011. The Floridian Island, a six-acre property with a large mansion on it, went up for auction in 2013 after the post-Hexum owner made some expensive updates, increasing its value immensely.

The estate on the island is one of the most impressive parts of it. It has three bedrooms and three-and-a-half bathrooms. It also boasts a plunge pool, rooftop observation deck, wrap-around balconies that provide views of the beautiful Florida straits, a gourmet kitchen decked out with granite countertops, and floor-to-ceiling windows. Not to mention, Melody Key has its own private beach.
