If there is one thing that I've learned from this pandemic it's that I will never be a landlord. But what does that do to rental supplies? I personally believe that the rental market will be ceded to large corporations like Invitation Homes and the like. Because only they will have the large portfolios to mitigate the idiosyncratic risk.
Or you could just go - gasp - the communistic way with city-owned cooperatives that build and rent out on a non-profit base with low-price housing in the center of efforts.
I know, what an henious suggestion! But it would be a way.
Is this style present in German? If so, does it work well? I'm curious how these situations do things like set prices for rent and are managed/accountable.
There are a lot of different models. But as I said above it's mostly (at least here in the Eastern part) GmbHs (a normal private-law company with resticted liability) that were founded sometime after 1989 by the city and got all the houses.
e.g. I am living in an apartment from one of those GmbH, created 1993, that got all the city-owned houses (roughly 10% of all bulidings). They also do management for other owners. They have renovated a lot of those houses and currently are doing a big renovation project on what was the post station/inn of the town 200 years ago (there are a lot of really old houses here).
It's something a normal person could not really manage to do, they have experience. And the "Free Market" would not have done it in 1990s or even later, since so many people left that the biggest housing problem was to tear down buildings.
In my old town there were two housing cooperatives, one I think from the city and one privately founded. There was also a GmbH for the water, gas and electricity infrastructure (Stadtwerke, as they were called not only there). The Stadtwerke were city-owned and used their surplus to subventionate another city-owned GmbH that hold the sports grounds and other "leasure" stuff that could not run profitable . (The theater has another city-owned GmbH itself, though :D)
But back to "public" affordable housing, I think THE example is Vienna.
https://socialhousing.wien/ About 50% of the people life in their houses.
If you want to get a feeling for this, you have to go through their complete website I think. I certainly don't know it good enough to give a "most important points" short summary. But you can get ~$9-14/m˛ new-build flats including passive houses in the best positions (they are the upper end). For a big city, those prices are quite cheap. Comparison: The lowest level in eastern Germany for renovated flats is $6.
