Close to US incase Med emergency,Need to know Real Estate market,Buy and rent.Is citizenship needed,dual citizenship?How does that work?Pros and cons of living out of country.Any info would be GREAT
Close to the US you have only two real choices, Canada and Mexico. Unless you are willing to live on an island.
Here you are in the Europe part of the site, so most people here live in, or like, Europe.
I think you will find that health care in most European countries is at least as good as what you would get in the US for the same money.
In England you would not need to learn a new language, in Spain you would find whole towns geared to elderly people from England and other northern European countries who live there because of the warm winters, (a bit like Florida) with health care given in English.
If you want to live in a country where your money will go a long way you will find that you need to learn a language that is not related to English, like the Slavic languages, if you want the language to be easy to learn, or English, your money will be worth less than in the US.
If you move in as pensioner, and are over 65, most people do not bother to get local citizenship, as the biggest need for it, work permits, is not needed.
If you bring enough money you are welcome to live in almost all countries, on a residency visa, without bothering with integrating or getting citizenship.
And if you want to be able to return to the US in case of need, medical or other, having an other nationality makes it much harder.
If you are able to retire at a much younger age, you will need to prove that you have a lot of money, or a good pension plan, so that the country you choose to go to knows that you will not be a burden on the country in the future.
Search your prefered countries and visa, or go to the site of the embassy of consulate of the country you are thinking about.
Each country has info.
But remember that in Europe your dollar is worth less than in the US, at least in western Europe.
