I think all we are learning from this thread is that there is a non-trivial number of tenants who are terrible and there is a non-trivial number of landlords who are terrible. The activity of renting a home is fraught with risk that your counterparty is terrible. The two parties' financial interests are often opposed, and state and local law tends to incentivize at least one and sometimes both parties towards being terrible.

I would never want to be a renter again, and I also have no interest in becoming a landlord.
