I’ve moved 6 times, so hold not allegiance to bricks and mortar, I’ve moved my memories with me. I’ve realised having moved this many times (to accommodate growing then them leaving to go their way, including grandchildren) that we need to adapt to the changes in our health and wellbeing.
I’d defo say a bungalow, not a flat or anything that you have to share with anyone, above, to the side or below you, as my garden which is small enough is my wee chill place. I also would suggest moving somewhere fairly close to shops or train station or has a good bus service for when you cannot drive, so at least you can get to shops and places of interest. It’s great having good neighbours, but they could eventually decide to move as we don’t know how life will go, so i agree with other post, maybe start looking at wee bungalows, perhaps drive into the area and stop for a coffee or a wee shop and get the feel of the place and the locals, and get excited about all the new places and people you’ll meet. Then you can invite your old neighbours over. Good luck.
