Betting Against Real Estate

The San Fransciso Chronicle reports on how you can bet against the housing market:

Do you think housing prices are near a peak but don't want to sell your house?

Do you drive a lot for work or pleasure, and wish there were a way you could insulate yourself against rising gasoline prices?

HedgeStreet, a San Mateo startup, has started an online marketplace that lets individuals bet on a rise or fall in the price of housing, gasoline and other commodities without buying or selling the underlying assets.

You haven't heard the last of this.
