If you're seriously considering retiring overseas rather than just visiting, the single most important detail to get right is your visa status. A tourist visa is not a retirement plan — most countries that are popular with foreign retirees offer a dedicated long-term or retirement visa category with its own income, age, or deposit requirements.
Common requirements across most retirement visa programs include proof of a minimum monthly income or pension (a military pension or VA disability income often qualifies, but documentation requirements vary by country), health insurance coverage, and periodic renewal. Requirements change fairly often, so always verify current rules directly with the destination country's embassy or consulate before making plans.
