x5Guy, I am not trying to be an ass, but of course the seller wants $8 billion for his house and the buyer wants to get it for free, but the price point at which the buyer and seller agree and are willing to "sell" and "buy" is market value. Keep in mind that the seller and buyer have to be typically motivated. The market value is the point at which those two parties agree. Without the seller you don't have that point and without the buyer you don't have that point. It really takes 2 to tango and they are both equally involved in the process.
