While I agree the housing crisis is, a crisis, I would also say these situations are v complicated.
DB is friends with someone with severe schizophrenia. They inherited a house when their mum died from alcoholism and its fallen into disprepair from neglect. There are shopping trolleys in the bath, the toilet is blocked. He was going to the toilet in the garden for months. Its full of stuff from hoarding.
Yet he refuses help, it's very much 'I'm sorting it out' and nothing gets done. It's very much a pride thing, fear of criticism and fear of being controlled.
Recently he received a large benefits rebate - enough to do up parts of it - its just been frittered on alcohol. I don't blame him, I just think it's indicative of his low functioning.
The council, under insistence from his dad, came round to do an assessment and he has accepted help from a volunteer group to sort the garden out at least.
From what I understand hoarding and accompanying issues are notoriously difficult for social services to make headway on.
In the bigger picture though this what years of underfunding mental health support in the community looks like.
