My wife and I just bought an oceanfront condo in the Philippines for $60k. That is at the higher end of the range, because we wanted to be in Metro Manila. You could get a place at a fraction of this price if you went to a smaller city province like Cebu or Bohol.

Central America, SE Asia.

Brazil is one of the most expensive countries around central/latin america and there's plenty of people living(maybe not living well) with this kind of salary, that on the economic centers, I believe there's plenty of beach cities(e.g.: in the northeast) that have ridiculous low costs of living because there's not much for the local economy to revolve at, only commerce, small biz, leisure and tourism so people make a little but live good lifes at a slower pace and if you've got a near-big-city-like income, or remote thing it's like you're rich if you go to a place like this...
