I lived in the Los Angeles area for 40 years. Moved to Charlotte, NC three years ago. I hate it here. Beyond hate it. I guess what a person’s retirement needs are would determine what works for them. For me, I need to be near a VA medical facility since that’s my med coverage. I also want to be in a state with no state income tax. And I’d prefer a warmer winter climate than what Charlotte has. Of those states, only Florida, Nevada and Texas meet my needs.
There is an Army hospital near Fort Bliss, draws a ton of retirees to the area. San Antonio would probably suit your needs, too.
