Retirement is a "heavy" at any age. Especially if the work was satisfying. Retirement at any age is a psychological whammy.
I retired when I was 58, almost 14 years ago. I stayed put and didn't move for a long time - the guys who retire and move to Florida all die quickly. All the things the guys said earlier are true- it is a culture shock whenever you move and things aren't necessarily better overall. Some things may get better; others worse. And we haven't much time left for replays. The cold VT weather finally got to us.
We sometimes perseverate too much about minor problem we encounter where we live. Every place in the world has minor irritations. Thee are as many irritations here as there were there, only it ain't as cold.
Unless you're stretched very thin, the tax situation isn't that important - the move will consume a lot of the tax savings anyway. There are many considerations such as energy costs. We paid about 5 grand/year to heat our Vermont house and at that time the taxes were about 13K for the house and 4 acres. The quality of life was very high and invariably that comes with high expenses. Hunterdon county in NJ is still incredibly beautiful. The northeastern part of the state is garbage but one doesn't have to go there.
Seventy is a watershed year - the future is now and there ain't a lot of it left that's quality time.
Before burning your bridge, how about, in one year, going on two or three South Georgia quail hunts; Anticosti for deer; Ungava for caribou and some of the western states for pheasant. Grouse in Maine. You can work, if you want to, in between your hunting trips and you'll be hanging with like-minded people. Your support network at home stays in place and you'll still get all the hunting you can want. See if that works for you.
Of course, if your neighbors' political ideology is so offensive then moving is the only answer.
Try making a list- list the plusses on the left hand side of the page and the minuses on the right. Add to it as you think of things and after a week or so you'll have a pretty good comparison.
But be certain before you leap- you'll never get you old house back.
