Our state don't own the housing but they do control it.
Landlords (like 90% of all apartments in Sweden are owned by giant housing companies) and they are forced to follow the housing laws, rent caps and tenant rights.
Basically no freedom to raise rents randomly, any actual raise is done within set parameters and as a tenant you pretty much hold all the rights as long as you do not break the rules multiple times.
Contracts are not time limited, rents are set (no highest bidder bullshit) and once you rent a place you can stay there until you die if you want.
Downside is our housing queue system (based on points per day) and in some areas like central Stockholm it can be a decade long in worst case scenarios.
We still have private landlords but that's the desperate option because they will charge insane rents for even the smallest place.
