Necker Island, British Virgin Islands. ~ Price: $100 million
This beauty is owned by Sir Richard Branson, famous for his Virgin brand, and it is part of the Virgin Limited Edition portfolio of luxury properties.
The island has everything needed to acomodate up to 28 guests in an amazing resort-like athmosfere.
The property for which Sir Branson paid only £175,000( $275,000) at that time turned out to be an amazing personal project and highly profitable putting it in the 4th position in our top 10 most expensive islands in the world rank!
With over 3 years of hard work and somewhere around $10 million the place turned amazing and it is now cashing in around $60,000 per night.
