It might not be the worst idea to make renting houses normal and just as convenient as owning. If rental laws were fixed to provide extreme stability and decent rights, you'd only own for investment purposes. And you wouldn't have extreme upwards pressure from renters trying to buy at any cost to avoid shitty renting conditions.

We really should allow renters to stay indefinitely at rentals and also pass on the general maintenance responsibilities on to them as well.

Renting things like appliances doesn't make sense since you require exclusive access to them and generally use them for their entire lifespan. While houses mostly exist before and after your need for them.
