Again, it all depends on what you require and how you want to live.

Even if I started out with nothing, with $100k I could probably buy a place outright (a truly run-down shack, mind you) and still have enough to bootstrap myself into life-long self-sufficiency(excepting maybe the internet requirement). There are very cheap properties (some rural, some urban) in many states (even Hawaii!), so it all depends if you want 1 undeveloped acre on a tropical island or 5 acres in the mountains of West Virginia with some 100-year-old moonshiner's cabin already built.
