That’s basically discrimination? Make a strict selection criteria, that’s fine. The city also has affordable housing for people who don’t qualify. You set what works for you, why do you care if it’s too strict?
I am not acting like there is an oligopoly, but not having tenant protections means tenants are at the mercy of shitty landlords. And there are a TON of them. Am I not supposed to have any rights, and the landlords gets to do whatever they want? Free market doesn’t mean regulation free.
Edit: you said “We should be creating incentives and making it easy for individual homeowners to become landlords (at least in Seattle) if we want the paradigm to improve.” - what do you propose? What about landlords who don’t want housing built because they like owning a scarce asset? What kind of rights do you think tenants should have?
