What do hidden taxes have to do with the price of a house? What is the function of supply and demand?
I live in an area where a house built and sold in the '60s for $25,000 sells today for close to a million dollars. You're telling me that the price will fall by 9%? Ha!
If the value of homes did fall by 9%, what impact would that have on the equity millions of home owners have worked so hard to build? What impact would that have on the economy?
The discussion has always been about the price of new homes falling with the removal of the income tax so your trying to misstate what has been sense is just more of your purposeful misdirection activity.
Even used homes would benefit from the FairTax though, as mortgage rates would decline making even used homes easier to afford,
Since you've demonstrated you don't "do numbers" I'll not give you any to avoid further confusion on your part - you're already confused enough..
