I never understood that attitude. I always took leases as a two-way street. That is, I'm free to leave and go somewhere else at the end of my lease, but the owner is also free to not rent to me at the end of my lease (with appropriate notice). It seems weird to me to have the expectation that if I sign, say, a 1-year lease that means I should have the right to renew that lease in perpetuity.
Use it or lose it I say. You wanna invest? That's what the S&P and index funds are for. Go thusly
I think this covers flat out most rental properties in California as well.
So the answer: California
I agree that this has an absolutely massive chilling effect on leasing & building, given that, reasoning from the past, any new development is almost certain to be subject to rent control within 20 years at most. I've never lived in a state nuts enough to have state-wide rent control before, it's interesting.
