We've seen what happens when you meet supply in a speculative bubble. The USA, Ireland, Portugal and Spain all had big supply and banks kept on lending into it because it costs them zero to create fiat money to rent out against land. Then you get a massive crash again. How would demand be if you force a big wedge of people who own/mortgaged more than one home to sell up? I think it would ease considerably. How many SF tech "entrepreneurs" are leveraged on housing? Flush 'em out with land value tax.
