I grew up in two different cities as aI
kived during childhood. I have lived in both those cities again, briefly, as an adult. Emphasis on briefly. About a year in each case.
The familiarity was great at first. But then you gradually come to terms with the fact that the people you loved aren’t there anymore. And that can be heartbreaking.
And often the place has changed, both materially and culturally. So you can get some shocks, in a way that wouldn’t happen if you’d lived there continuously as you’d gradually adapt. You can’t step into the same river twice as they say.
That said, we did consider moving to one of them, as there was an option of a branch transfer with work, to a few places and that was one of them.
We went to view a house to help make the decision. The answer was “not now but maybe later”. But that decision would be made at that point on the matter of facilities and amenities.
So I would say there is nothing wrong with a visit, or even visiting regularly and seeing how that develops.
