What an interesting and thought provoking thread! I retired at age 55 in 2008 after a chequered career which finished with me as an investment and tax planner at HBoS, a job which I grew to hate, and with the 2008 financial crisis looming, I decided that this was going to be horrible and I wanted to be no part of it. After I had left, I didn’t so much as take a single backward glance over my shoulder. My wife initially went 3 days per week part-time in her job as a health visitor, but found, as many part-time workers do, that she was expected to service a full-time caseload in 3 days per week for part-time pay, so she took early retirement as well.
Early retirement was one of the best decisions we have ever made. For our final year of work I crunched the numbers and we tried living on our projected pensions, taking into account that there would be no commuting costs, no National Insurance and no pension contributions, and we were both pleasantly surprised at the lifestyle we could have on a relatively modest income, and that has continued to be the case.
We have lived in the same house in West Devon for the last 37 years. It’s a friendly area, but then, as has been observed elsewhere, so is Gloucestershire and Northumberland. We have lived in Cumbria, and visited Gloucestershire and Shropshire, North Yorks and Northumberland multiple times and can vouch for the friendliness of them all. I get the feeling that local friendliness is directly proportional to the distance from London, but I stand to be corrected.
We have 2 children. A bachelor son in San Francisco who is brilliant at keeping in touch. He has no partner or children, but he is in touch most days via WhatsApp with interesting snippets and/or banter, and we video call most weeks for about an hour. He’s back in the UK maybe 3x per year, and we try to get out there once per year, although that is on hold at the moment due to the political situation. I doubt whether we would see any more of him even if he lived in the UK. We also have a married daughter with our 2 grandchildren in Surrey. Our grandson is mildly “special needs” and our daughter has made it explicitly clear that if one of us needs help in our later years, not to factor her into any arrangements, so we haven’t, and are staying put. We have an excellent local health centre where we have no difficulty getting seen, dentist and gym where my wife does exercise classes and I play racketball twice a week. We have many friends and I lead the local U3A cycling group on our monthly rides. For us, any attempt to relocate and start afresh in our early 70s would almost certainly be a catastrophic mistake.
The key advice I would give before moving areas is to consider the extent and depth of your personal infrastructure in terms of healthcare, dental care, clubs, friends and general environment for what you enjoy doing. How easily would it be to duplicate, or improve upon, elsewhere? What are the family dynamics? Do your children/grandchildren live nearby, and how often do you actually see them? How often would you like to see them? How often would they like to see you (not necessarily the same thing!). Consider that whilst grandchildren under 10 often love time with grandparents, those in their teens maybe not so much. They are not young for long. Be a bit selfish. After a lifetime of work, retirement should be some “us” time, whilst you both (hopefully) have your health. Get the big stuff done early whilst you’re still able. For instance, the LOML and I trekked across the highlands of Ethiopia (known as “The Roof of Africa”) when we were 62. I’m not sure we could do it now at 72. What do your family genetics look like? I have already outlived all my grandparents, and only one of our parents has made it past 80, so we’re trying to buck the trend

If you really want to try a different location, maybe try renting for a year on a “try before you buy” basis before committing to a sale and purchase? So many considerations to make, but I wish you well with whatever you decide to do.
