Depends on what kind of restrictions would be placed on the landlords.
Remember, the end game for the Communists is to control housing, by driving people away from being landlords and have the government take over housing.
Yep, we’ve had only one tenant in all my ownership years that had housing assistance. The local housing authority, basically, owns that unit. They can inspect it at any time, make you make improvements to the unit (even if they are unnecessary or the tenant’s fault), and deny any rent increases that you may want.
