As a home owner, the cost of “what you’d have to pay to own the home” is extremely variable and to an extent down to dumb luck.
I think it’s sufficient to say no individual should be able to rent out more than X number of homes where X is what that individual could reasonably take care of. I’m okay with corporate rentals, particularly in the case of complexes as well.
Basically, I don’t think small business or individuals that live in the area that do rentals are the problem. If someone wants to rent out houses as their primary source of income … sure why not.
It’s like anything else though, there needs to be reasonable limits to stop gluttony. I think a limit of “you can have 1 rental property” is way too low though.
