I agree with your points but I’m curious what your solution is to single family homes that are being rented out? The obvious one is everyone who wants to buy a place is able to, but not everyone wants to buy yet (younger people, people who want flexibility, people who know they are moving [only in that city for school], etc). Having some corporation own everything is also obviously the worst option, but that only really leaves the government and the mom and pop operations (that is people who own 1 place and buy another to rent it out). Should all single family homes be run as co-ops? Torn down and rental apartments built instead?
Again, I agree that single entities owning multiple rental places is a bad thing, but there doesn’t seem an obvious replacement. So I am genuinely curious as what can be done?
