In the ideal world local authorities would build their own houses, cutting out the developer % and rent directly cutting out the landlord %.
However they don’t do that.
They used to, I can’t remember why and when they changed. I do recall a uni economics lecturer talking about it but that was decade ago and I’m sure the logic has changed.
When they did that it wasn’t ideal, they built vast estates creating ghettos. And then their policy was to let tenants buy.. like in the UK, thereby depriving the LA/landlord in the future. Now they don’t have the expertise so restarting it all is a major expense and not a vote winner as it’ll take years to regroup.
My dad’s family were relocated to a massive housing estate from inner city, then they bought their house.. then the fair deal got a % of it back when nana developed Alzheimer’s and lived for over a decade in the hospice. But meanwhile the house changed hands a few times and is now worth well over half a million. But the LA don’t have it or a replacement.
