Here's a scenario that's repeated so many times and been a failure. Couple goes on vacation to some far away place. Enjoys it immensely, decides to buy a "retirement" home there, retires, stays one season, they miss the kids, the grandkids, the rest of the family, their old friends, house goes up for sale, they move back to their old home area and more often than not, take a financial hit.
One of my relatives is in real estate in South Florida and has seen it so many times. Says number one rule of buying a retirement place of residence away from family and friends: RENT for ONE full calendar year, then decide. YMMV
