One thing I've always wondered is why we as a society even let real estate be a thing that people can buy a lot of. Why does an individual get to buy, say, 10 buildings and rent them? The title "land lord" even seems like a holdover from some feudal time.
Not that I think you completely outlaw the practice, but why not start taxing after, I don't know, you own 20 units or something. Just figure out some sort of scheme that disincentivizes people from hoarding a resource required for life. I'd much rather rent from someone that lived in the building and actually cared for the place than some random LLC in Florida I mail checks to that can't be bothered with anything.
