Aside from the fact that this whole argument is risible, I somewhat resent the implication that my renter neighbors are somehow responsible for crime and hygiene problems. I think it's ironic that you think my argument is the one cabined by limited experience of the world. There is nothing moral or prosocial about financing residency with a mortgage versus paying rent. If anything, housing policy throughout the US is far, far to biased in favor of owners over renters.
The issue here is short-term rentals, not the deeply weird idea that the only properties that should be available for rentals are multi-family dwellings.
