For generations, the process of buying and selling a home never really changed. A homeowner would try to estimate the market value of their house, then tack on a little extra to give themselves some negotiating room. That figure would become the listing price. Buyers would then try to determine how much less than the full price they could offer and still get the home. As a result, the listing price was generally the ceiling of the negotiation. The actual sales price would almost always be somewhat lower than what was listed. It was unthinkable to pay more than what the seller was asking.
Today is different.
The record-low supply of homes for sale coupled with very strong buyer demand is leading to a rise in bidding wars on many homes. Because of this, homes today often sell for more than the list price. In some cases, they sell for a lot more.
