It's not a care home, Norah. I had various expectations in my head when I went visiting my friend what it would be like, and of course there will be a % who are getting close to not managing, but what I found even tho it was 75 and over were a lot of very bright buttons, ex teachers, university lecturers, zipping in and out: some sitting around nattering together, most with wi fi in flats.
What I am wary of, having lived in a block of flats before, is the pros and cons of getting along with neighbours and any cliques, but reading about some GN's difficulties with difficult neighbours, its not exactly unusual, is it?
The re-sell problems are just as described, except that as things stand locally, there are not proliferations of them, its not a "retirement area", and if you are canny, you get one of the 8 or so flats with the lovely sunny views on the right floor, that sell the most quickly.
Its one of those things I should have thought about 11 years ago when buying this house: its great, I could stay here - but without a car, no shops, its a car to food, GP, cafes, pool, any friends, everything, and family are 3 hours away anyway.
