These seem like good and reasonable ideas, but it may be a mistake to ignore how this used to work in the past. There is a state called market clearance when a market supplies at least enough to meet all demand and possibly offer some participants multiple options. With the current deficit of residential units we are very far off from this state of market clearance. When the housing market clears residential units become extremely risky investments as they are assets with declining asset value built in through the need for constant maintenance in order to retain habitability. As long as the housing market has a large deficit it is not clear that any attempts to control the market with strict investment rules will be able to overcome the market forces that are inflating prices.
