Because median list price and median sales price measure two different pools of homes, and sellers price with a cushion on top. The list-price median reflects what's currently for sale. The sales-price median reflects what actually closed, a different set of properties. Compared in aggregate, the two can show a big gap even when individual homes are selling close to ask. Add ordinary pricing behavior. Most sellers deliberately list a bit above what they expect to net, planning to give some back in negotiation, so the closed number typically lands under the asking number. And even in a solid seller's market, roughly 30 percent of listings take a price reduction before selling. Layer those together and the aggregate sales figure sits below the aggregate list figure almost by design. The stretch when homes routinely sold above asking was the unusual period. Heavy competition and thin supply pushed buyers to bid over list; in normal conditions, closing a little under list is exactly what you'd expect. A state showing sales below list is often just the ordinary mix of pricing cushion, price cuts, and two medians measuring two different baskets of homes. On its own, it says nothing about weakness.
