The housing shortages are caused by politically induced scarcity through zoning density restrictions and overuse of historic landmark status. This has been explained by many including Harvard economist Edward Glaeser and recently referenced by Economics Nobelist Paul Krugman. In microeconomics this polticially induced scarcity is called "rent seeking." Fix the "rent seeking" by overturning the zoning and landmark status laws that create the scarcity and your housing prices will drop.
