YANBU.
A third of households in the 70s lived in social housing. But so many have been sold off, and not enough built or bought to replace them.
I would like to see a system where virtually all housing was owned by the local authority by default, and as many as were needed for social rent were let out to people (with a secure/assured tenancy, so they can stay as long as they want), then the rest could be sold to owner-occupiers.
Then if they want to sell it, it goes back to the council so they can reassess their stock and decide whether to let or sell it again.
Exceptions could be self-build, where the building family owns it to start with, but then if they sell it (rather than hand it down to their children to live in), it goes into LA ownership.
Even holiday accommodation could be owned by the LA (e.g. mansions and caravan parks etc).
But anyway, nobody should be making profit from housing, e.g. buy-to-let, property businesses gouging fees every way they can etc. And nobody would sell directly to other private individuals, so the housing market wouldn't be so unstable.
If two children have inherited a property and can't agree what to do with it, they wouldn't be allowed to sit there letting it out and making money from it; either they'd have to sell it to the council, or live in it. And even then, if one can't afford to buy the other out, but only one wants to live there, they could let the council buy it and then have priority to rent it back. Same for anyone who wants to sell their house; they could rent it back afterwards instead of moving.
And since it's council-run, not government, there would be more housing sovereignty as it's easier to have control over local issues.
So this could start by councils (or ALMOs) automatically getting ownership of houses that are left empty for a certain period of time, and refurbishing them to add to their stock. And at some point (which could be different for each council), once they have enough money to start buying them, private sellers would be forced to offer the council first refusal. And then later, once they'd built up plenty of reserves, everyone would have to sell to them. There could also be government grants for councils buying houses during the transition period.
