10. El Salvador
Cost of living index: 45.95
International Living describes this place on our list of cheapest places to live in the world on the beach as warm and friendly. While it is true the most tourists and expats skip El Salvador and go to the more popular Guatemala and Costa Rica, that could be your advantage. Their rather quiet tourism industry makes their beautiful beaches less crowded and almost all yours to enjoy. There are also lakes, cloud forest rails, and volcanoes to explore. Cost of living’s pretty neat, too.
