In Arkansas you only have to live in, maintain, and pay taxes for a period of 7 years. And there are A LOT of cool abandoned homes in the Ozarks.
Hmm...
Isn't part of the problem with a lot of these ideas that -- given that you are not the legal owner of the property -- you don't even have the right to get basic utilities turned on? Like in the story I linked above the guy was squatting in the house without power.
