it's a good diea but from a personal perspective (my aprents who are older and in HA housing with spare rooms) the alternative offers they ahve ahd have made the move unworkable, they'd have liked to trade down otehrwise.
The reasons are;
The places offered have been miles away, Dad still works graveyard shifts, can't drive and busess don't run there at that time; he tries to cycle ATM but has no feeling in one leg from the knee down and is losing the ability. I am not sure a seventy year old and a four mile walk at 3am is copatible. He can't afford not to work as his pension was lost (otherwise he'd have bought his own bungalow years ago as per paln).
Mum is sole carer for Grandad whose house she could not reach from suggested area, at 94 I suspect his lence will soon be revoked!
They would lose all contact with friends and neighbours again due to lack of suitable public transport. I live in a different country (withi UK), sisters work very long hours. It would be an incredibly lonely existence for them.
there is an extra factor in that my BIl had to move away to find work post redundancy so my sister is in practical terms (far from emotional I know) a single mum working shifts with 2 boys, parents are only childcarers whoc an manage her 24 hr shifts. Now, that's not a reason not to downgrade but adds up with other factors- with Dad coming and going all hours the kids need a bedroom away from main living room 3 nights a week.
Now I know some people in need of a home will shout at me: please remember I am NOT my Mum and Dad! In fact I am classed as vulenerable to homelessness and could well be at any time so absolutely I get it, but i don't think Mum and dad are wrong either. They would be if the housing offered them were in the same area they are in, mind, but that area is already bult up and new estates are built in the middle of nowhere . Address that, amke alternatives accessible for the many variations of older people including those like Dad who work and yes, absolutely.
