@onlychildhamster No I appreciate she couldn't buy in London for that.
maybe I am being really naive here but wouldn't there be someone willing to cook, clean and do some simple chores, help her out for reduced or even free rent?
No, I don't think so. Birmingham is my closest big city - Rightmove shows a couple of large double rooms for rent in nice streets for £450... You'd get such a low amount of chores or care for that. In Coventry, you can rent for £250 - 300 a month with bills included.
And the legal position for being a lodger that pays no rent would be complicated on both sides. I know that's overlooked in London because prices are so crazily out of reach for most people, but it's not anywhere else that I'm aware of.
It's lovely of you to be trying to help her, but it sounds like a pipe dream. She can have the live-in carer, in all likelihood, if she stays in London - if she has to leave, she's likely going to have to pay for any care that she needs, and a lodger won't be reliable.
Is learning to drive at all realistic? I'm wondering about villages and more rural places, but if learning to drive isn't an option, that's probably not realistic.
Would she qualify for supported living? You have to be over 55 where I am, but depression can be a qualifier, and here she'd only really be able to rent, but I presume you'd be able to do shared ownership in some areas on similar schemes... That might be an option? I think the terms of each scheme vary, so she'd need to look into how much care is provided or how much it costs, etc.
I'll keep racking my brain.
