At the same time as buyers flood the housing market and existing homes are in such high demand, the cost of building materials like lumber has skyrocketed. This, in turn, has driven up new construction costs, causing homebuilders to grind the pace of new housing starts to a halt. As a result, existing homes are in even higher demand. Meanwhile, homebuilders have subsequently passed down their higher construction costs to customers, driving up newly constructed home prices by 15% or greater. That has only further tipped the scales in favor of sellers of existing homes versus sellers of newly constructed homes perhaps for the first time in over a decade.
