For generations, the homebuying process never really changed. The seller would try to estimate the market value of the home and tack on a little extra to give themselves some negotiating room. That figure would become the listing price of the house. Buyers would then try to determine how much less than the full price they could offer and still get the home. The asking price was generally the ceiling of the negotiation. The actual sales price would almost always be somewhat lower than the list price. It was unthinkable to pay more than what the seller was asking.
