Microsoft cofounder Paul Allen lives a pretty fabulous life. With an estimated net worth of $18 billion, he's the 26th wealthiest man in the world, and he has the fancy yachts, planes, and lifestyle to prove it.
Allen also collects a ridiculous amount of properties across the globe.
From a hilltop mansion on the French Riviera to an entire island off the coast of Washington, Allen has made his fair share of blockbuster purchases over the years.

He bought Allan Island, off the coast of Washington, in 1992. Though he initially had plans to build a dream home on the island, its secluded nature and lack of electricity made construction difficult. He sold the island in 2013 for a discounted $8 million.
