28. Leonardo DiCaprio – $1.75 Million, Belize
The world-famous actor didn’t just buy a mansion, he bought an entire island. Blackadore Caye is 104 acres in Belize which is big enough for a few dozen homes and villas. Talk about a real estate investment! The island is on the market for $5 million and may be developed into an eco-resort, with every luxury being environment-friendly. We can’t even imagine the insurance for an entire island resort, but it’s got to be astronomical.
