Maybe this will get people back into housing? Sell property value insurance via Puts and calls. That way you can hedge against losses (minus the premium of course and deductible if you buy cheaper lower strike puts) And allow homeowners to sell covered calls on their home as well so they can collect a premium. (of course of the house gets called away, they have 24 hours to move out on assignment notice) IF the house price collapse, you can call up the bank and exercise your put and whoever sold that put short will be forced to take 1 house unit, bank gets cash and you are good to go free and clear. This would provide transparency and a more liquid housing market.
