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.
