CTJ: if I was serious about moving I would look, first, at Ecuador. Ecuador will give you permanent residency, with a path to citizenship (something very valuable in the long run) in return for spending as lttle as $50K on a piece of property. I think they also have an even cheaper pension program, where your social security, alone, will qualify you.
Oh, I was wrong. It's easier than that:
"Recent changes to the law have made it easier to establish legal residency in Ecuador. The minimum income requirement to qualify for Ecuador's pensionado visa was recently lowered to one month's minimum wage, which is around $400. You might also be able to qualify for residency through the country's investor visa program, which requires an investment of at least $40,000 in either real estate or a local bank certificate of deposit."

Let me know if you are going. Maybe we can go together and get a package deal! ;->
