Lots of factors go into making this decision. I just turned 70 and a few years ago, my bride and I were at the same crossroads.
I was determined to move to Tennessee, the eastern part, trees, fishing, hills, remote, get a few acres, burn wood, grow our own food, animals, no people or not many anyway. I even planned a trip to scout it out but never got around to doing it.
We live in north central Kansas and taxes are high and the scenery isn't that great. There are several things we have learned as we looked at the perfect place to move to. We eliminated some of them immediately.
We had no interest in the humidity of Florida. Daughter did an internship there said it was the hottest, most humid place she had ever been. She later lived in Bentonville, AR and it was plenty warm there, now she and her husband and living in Breckenridge, CO for a year. I am from Nebraska and have relation still there around some beautiful areas of trees, hunting and fishing but taxes are way too high there. South Dakota looks great, some fun things to do and lots of places to go, taxes are great but it is COLD. Same with Wyoming and Montana. Thought briefly about Utah but it just doesn't grab us. Idaho was talked about but we never got interested. Colorado has favorable taxes but the cities rule the roost there and are way too liberal for us. So here we sit several years later in north central Kansas with to high of taxes and a lib governor.
When we get the urge to think about moving we start looking around and putting pluses and negatives down and there are always plenty of them. If a person can sell their home and move to where houses are less expensive that is a plus. I would suggest doing some google searches on which states are the cheapest to live. Oklahoma is one of the best in that regard but comes in low for health care which is always a bigy for us older set. Arizona is out of water so that is a factor there and going more purple all the time.
We would sit down and do some research and one day my wife made a comment about us moving to Tennessee. She said we would get moved down there and I would die leaving her all alone. True possibility. No relatives around. Here we have a nice but not extravagant home, a couple rental properties, lots of friends but most of all a great church. Lots of factors to consider, decide which is most important to YOU!
