Meh, you can pick-up a real tropical island for $1 ~ $2 million. And I don't mean a sandy atoll that might disappear overnight, either. A real decent island with main house, solar or wind turbine, diesel generator, water filtration (reverse osmosis for desalination), AND some bungalows for guests. Was checking out some listings of islands for sale awhile back and was really surprised at how "cheap" many were. I thought they would be 3x ~ 4x as much. I mean, you still have to be well-off, but you don't need to be Mitt Romney rich.
