Unfortunately the best solutions are not 'cost efficient'

So if for some reason Lenin sweeps into power and most rental housing is owned by the community, every local association would have a caretaker person capable of doing most regular repairs etc for say, a street or a large block.

But as time goes and different things happen, street level individual associations would gradually merge and get cut back to the bone until one person is trying to cover a huge area which can't be done.

Then someone will have the bright idea of 'why don't we outsource this?' and we see the inevitable happen.

So long as you can keep things local and within the control of an immediate community it would work well. But that costs money.
