To add to your point, I live in a suburb/city that effectively bans rentals by making property taxes extremely expensive if the property is not both owner-occupied and a primary residence (homestead taxes). This is coupled with widespread HOA agreements that explicitly ban renting/subletting to not-close-relatives. The unsurprising effect is that higher income families live here and the cost of running the schools is consequently low. There are some other suburbs, but in that case you're committed to private schooling of your kids.
