Being older you need to factor in healthcare. I didn't when I moved remote, and it was a big mistake. I firmly believe my mother died of cancer because I convinced her to move to a rural local that didn't have the quality of cancer care that she would have had access to if she stayed in Santa Cruz. My advice is pick a touristy area that has enough money/population moving through to have a bit better medical system than your average remote area. Definitely buy a lifeflight.org membership every year if you go the Montana/Rocky Mountain West area.

I also recommend finding a town that caters to rich tech people who want to live this remote fantasy, there are quite a few of them. It's so much more enjoyable than the actual remote living towns that no one wants to be in so they're just an aging population of dead enders and people hooked on drugs. Or at least an area with a University nearby so that you can go somewhere with some energy/vibrance and the latest cool trendy food. The realities of dead end small town/no town america can be pretty soul crushing.

Disney style curated small town america catering to the wealthy can be a pretty great place to live and have energy/vibrancy. Plus you'll have a good revolving supply of new people cycling through thinking they want to live the lifestyle (before the realities set in) bringing in the latest trends, starting food places, etc. Just make sure they aren't the 'escaping from California' types blathering about how great it is to be in a 'free' state and be away from commie land. That toxicity can overload a small community quick. You can get away with 'individualists' in a larger community where their actual freeloading on society is subsidized by normal people, but with too big a ratio basic civilian institutions get paralyzed for years until people remember/relearn society requires a social component.
