Colombia I think is a bit underrated as a retirement destination. I looked into it and if you invest 200K there, which can be just buying a house/property, you can get some sort of visa/residency. I could basically trade my house for one down there and am guessing it would be a bit of an upgrade over what I have here. Health care is cheap and good. I am leaning toward Mexico if I do it though, I like that it's drivable and I think it would be a little easier to adjust to things culturally there than in some of the other countries mentioned here.
