I knew a guy that would spend half the year living in Bali. He's a trippy-hippy dude who makes his money doing astrology readings.

Even though it didn't really fit in to how he wanted to live his life, he ended up getting a local housekeeper. She'd basically just do all of his shopping (groceries, clothing, whatever) and pay the local price, rather than the tourist price. With the money he saved, he paid her above market rates and still managed to save money on the whole deal.
