Go with your gut Mynxie. I live in an extremely spacious and well appointed 1st floor flat. I had it completed gutted and updated which cost me a small fortune.
I now have osteoarthritis in my spine and I have to open my front door, then open the communal hallway door, go down the stairs, open the main front door, down a concrete step, walk across the courtyard and then across the garage block to get to my car. And that's without the number of times I have to go down and back up with the rubbish. There's no way I can do any decent amount of shopping as I can't carry it all the way up to my flat so I'm dependant on home delivery. I frequently talk myself out of going out as I'm in pain by the time I get in the car. So I'm becoming too isolated.
So after a lot of thought, I've bought a bungalow. It's smaller than my flat with way less storage space so I'll have to sacrifice some furniture and other belongings. It is however nearer to my family which is a huge plus, but it does need work doing to it which I know will be frustrating but I'm going to grit my teeth. The garage is accessible from the front door, the back door and the back garden. I can potter in the garden (it even has a little greenhouse and a potting shed) but have people lined up to do general maintenance and the donkey work.
I've spent many a sleepless night wondering if I'm doing the right thing. But before my divorce I lived in a 4 bedroomed detached house with a study and utility room - I then moved into a 2 bedroomed 2nd floor flat, but I soon got used to it.
Only you know what is right for you and if it feels right - do it. But I wonder if it does feel "right" if you are asking others (and let's face it, strangers, but in the nicest possible way!) for their opinions?
Good luck whatever you decide!
