You gotta admit, there are some crappy islands out there.
"Unlimited water supply", no shit it's an island, unless they mean its also flood prone from tropical storms.
"Fantastic views"...........of the ocean, 360 degrees. All day.....everyday......year after year....
"15miles from the mainland, ensuring absolute privacy".........you ever swum 15miles in an emergency?
"Pristine wilderness"..........no infrastructure, amenities or anything at all, you'll live in mangrove swamps like tarzan and fight beligerent monkeys for scraps of edible bark and leaves.
"absolute security"........the nearest island is a military base.
"Experience the everyday adventure of your own private island"............pack plenty 'o heat, coz fish poachers and drug runners will likely try and kill ya.
"Formerly a resort" ............will cost twice the price of the island to bring it up to scratch.
Disclaimer-those quotes are not from the linked site, i just made them up to illustrate some points.
Still, there ARE some amazing joints out there, but unless your intending to go robinson crusoe, better bring a few billion.
I suspect thats WHY there are still so many islands up for grabs, im sure many owners simply go broke, they go for the dream, leave for the reality of the massive expenses involved.
