In practice you can&#x27;t, but you can short the banks lending into this bubble. Also building companies can be shorted.<p>The problem with going short on something like housing is the market can stay irrational longer than you can stay solvent. This bubble is being pushed by buyers who are not looking to make money, but to get money out of certain countries and providing a safe haven to flee to. Unless this changes then things won&#x27;t get more rational.<p>If you had enough money you could short the banks and then whip up a media campaign of anti-foreign investment and xenophobia. Scare the market enough and you might get it to crash.
