The quickest way to build new housing is to turn short term lets (e.g. AirBnB) back into long term lets. A slower way is to extend and improve public transit (so effectively growing the desirable 'inner city' area). Affordability would benefit from rolling back some of the financial engineering that makes people believe they can pay more than they can actually afford.
