Odd Question for You Guys

I look around zillow a lot just for fun and could not help but notice how inexpensive lots were on your island. I'm not talking about the ones on old lava fields, there are places where you can buy empty suburban lots for 5-10K. Even where I live, you can't buy a piece of swamp for that price.

Is there some sort of catch or is the isolation/cost of living enough to keep most people away?
