I know exactly how you feel Ippy. A house does have to feel right if you buy & intend to stay there.
The house in which I live has always been a happy one, we moved here just over thirteen years ago (eldest daughter was 13,youngest 10) but bought from my parents who wanted something smaller in same vicinity & it had been my home from age of eight. They offered house to me or sister but sis was happy in her home which was quite big (3 kids & nanny), & she's still there. Charlie & I lived round the corner with our two in a very nice but smaller, more compact, house. I wanted something bigger so what happened was we 'bought' each other's houses. My parents lived in my ex house until both died & now eldest daughter bought & lives there with husband. It's funny in a sense becos looks like we have a tradition of buying hosues within family but it's just us (my parents bought from my grandparents when mum was eight).
Saw cousin and his wife & eldest+ family yesterday at my sis in law's, we travelled home this morning & had lunch together en route. They are a bit older than us and plan to retire year after next when they'll think of buying something smaller. We talked about moving & what sort of place we'd like forever. I was mindful of friends of ours who always said they'd have a flat when retired; they've had two very good flats & now want to buy a house having decided living in a flat is not for them!
I've been happy in all my homes so far but we will definitely move when we retire, maybe sooner. This place is too big for two people, incorporates a self contained flat in which my nephew & fiancee live at present but they will move soon, are looking to buy; we also have a "Filey cousin' in two rooms + bath on one side of the house, he's a student in London. When they've gone we will seriously think about it. The question is,"Where?".
It has to feel right. Not overlooked, solid walls & reasonably peaceful, not too far from where we are now. We have time to look around.
LR I'm glad you're content in your home, same to you Susan, sounds as though you've had an interesting life. I've never lived abroad.
