The actual value is what the market will pay for the home.
If you buy a house for $260,000 are you going to sell it for less than that? Of course not. Nobody will (excepting distressed sales).
Your position that people will begin selling there homes for less than they paid for it is absurd.
But aren't you one of the guys that claims that cutting prices will increse sales? To be consistent, you have to admit that raising gross house prices will reduce house sales.
