Landlords are the reason housing is so expensive. By buying up realestate and renting it out, landlords are directly contributing to the scarcity. Personally housing should be a human right. If you don't want to go that far here's a different solution. Literally just make apartment's buyable rather than rentable. Don't allow landlords to buy up all this realestate thus raising prices by creating a fake scarcity of housing. If landlords didn't own all of it, and people could buy apartment's rather than rent them, the prices would lower and become more accessible for people
