4. Arizona: Sun, Scenery, and Established Communities

Arizona rivals Florida when it comes to master-planned communities designed specifically for active older adults. Cities like Scottsdale, Mesa, and the famous Sun City offer year-round sunshine and a low-humidity climate that many find beneficial for arthritis and overall mobility. For single retirees, these sprawling communities provide instant social networks through golf clubs, hobby shops, and volunteer organizations.

The state does not tax Social Security benefits, and the cost of living—particularly outside the immediate Phoenix metropolitan core—remains competitive. Arizona appeals deeply to the independent spirit; its massive state and national park systems provide endless opportunities for hiking, photography, and outdoor exploration. You get the benefit of a stunning natural landscape alongside highly developed medical corridors like the Mayo Clinic in Phoenix.
