More than one-third (34.1%) of U.S. single-family homes for sale in December were new construction, up from 25.4% a year earlier and the highest share on record.
Newly built homes have taken up an increasing portion of the U.S. housing market over the last 10 years, with a major acceleration in mid-2020 after the pandemic began. Homebuilders have been busy trying to make up for the lack of existing homes on the market and keep up with high demand. There has been a surge in homebuyer demand since the start of the pandemic, stemming from low mortgage rates and the prevalence of remote work. At the same time, some homeowners have opted to refinance or remodel instead of selling, intensifying the shortage of existing homes for sale.
Overall inventory dropped to a record low in December. Inventory of existing homes fell 14.2% year over year in December, and there was a record-low 1.8 months of supply. For new homes, there was 6 months of supply and inventory was up 34.8%.
As the share of homes for sale that are newly built has edged up, the share of home sales that are new builds has remained relatively consistent, around 11%. This dichotomy is another indicator that homebuyer demand is far outpacing supply.
