I do not see it coming about because there are too many people tied to the complicated system we use and not just those with deductions. I would guess some of the real high rollers do not have house payments, as well as some of the folks who have owned their house for 50 years and paid it off a long time ago. It will be interesting to see what each party says, but I am not sure the Republicans want to upset the apple cart with mortgage deductions. I have no idea if it will erase that much valuation, but that might be a stimulus to the economy.
