When DH got early retirement from his DC job and we decided to see what life was like on the west coast, I went on an exploratory trip by myself. We thought we would like the west coast, our children were all grown, married, and living all over the country, and we were still young enough to take crazy chances. Things that become important as you advance into old age (such as the difficulty of climbing stairs) didn't even come into the picture.
I started in CA and stopped overnight at each of the towns I had heard of, or we had visited before, which we thought were possibilities, but didn't feel I had found the right one until I accidentially discovered Bainbridge Island, WA, which I fell in love with instantly. We both returned there shortly, and DH loved it just as much. So we sold our house, packed up, and drove across the country, an adventure in itself.
We bought a brand new house still being built, just from seeing the plans. Crazy, but turned out to be the best decision we ever made. We lived there very happily for 18 years, until we finally did reach old age, and his health required us to live near at least one of our children. So we returned to Maryland and got a lovely apartment in a 55+ community. Our son lives nearby, and we already had lots of friends here.
So, our dream home was great for our needs at the time, but sometimes life changes what you need. (The stairs are one example.)  I guess my point is, check your emotions when you visit the place you are thinking of moving to. All sorts of factors come into it, such as closeness to family, climate, affordability, general vibe of the place, how it suits the stage of life you are in right now. If it feels right for you, almost like falling in love with a person, you will know.
Getting friendly, welcoming advice from all over is helpful, but ultimately, the decision is a highly personal one, and the place has to be right for you... that's really all that matters.
