I think the main argument they are making is that affordability is less a demand/supply issue and more a tax policy issue. Implication being: if you cap rental income, you'll see a fall in private landlords but not necessarily less housing stock than if there were no rent controls. >I'm not sure what they're pointing to as the reason for housing prices if it's not supply and demand. They are saying the uncapped rental market makes housing as an asset class extremely profitable i.e. simple supply & demand argument is not strong enough alone to be the only driver.
