If you are not very wealthy, but still want to enjoy a high-quality life, one option is coming to the Philippines.
First of all, we need to understand that this group of islands is huge, therefore it is possible to find our favorite spot here. We all know Manila is a dangerous city, but there are many places where safety is not an issue. The most popular expat locations are Cebu, Clark, Subic, Baguio and Iloilo.
Second, the Philippines is a very affordable country, however you want to be close to a nice hospital with decent standards. That is the other side of the coin: cheap but not Western quality. Still there are options. You just need to look for then.
And third, tax wise, if you are an alien resident, you won't be taxed on the money you make abroad, so basically if you don't work or have a business in the Philippines, you don't have to worry about paying taxes here.
