Retiring across more than one location can be part of a holistic plan that blends health, finances, lifestyle, and legal considerations. Beyond buying two properties, you could rent one, or both depending on your capital and flexibility. Health and mobility may change with age, and by 80 or 90 you might prefer a more sedentary life in one place. For those with multiple nationalities or long-term residency rights, extended stays abroad can open even more possibilities.
