Shoppers walking through a brand-new house have spent most of the past decade bracing for a markup. Builders put in modern wiring, fresh roofs, and bigger kitchens, and buyers paid a premium for all of it, along with years before anything would need fixing. Anyone watching a budget tended to steer toward older housing stock instead, trading dated systems for a lower price per square foot. The math has flipped across a large share of the country, where a newly finished house now costs less per square foot than the resale home a few streets over. The change matters because affordability is the hardest obstacle in American housing right now, and plenty of buyers have ruled out new construction on price alone.
The split comes down to how differently the two sides of the market have behaved since the pandemic. Builders kept starting houses even as buyer demand cooled, and unsold new homes piled up to 9.6 months of supply by July 2026, compared with 7.6 months two years before and the six months or so on hand in the summers of 2018 and 2019. Many existing owners locked in mortgage rates near 3% and built substantial equity during the pandemic, so cutting an asking price holds little appeal, and anyone who doesn’t get an acceptable offer can relist the house as a rental instead. Resale inventory remains 17.1% below its pre-pandemic level, leaving builders to do most of the discounting and most of the incentive-offering to clear what they’ve already finished.
Zillow measured median price per square foot for new construction and existing homes across 50 major metro areas, along with the share of sales new homes accounted for over the 12 months ending in July 2026. Nationally, the median newly built home sold for $205 per square foot, $7 under the $212 existing-home median, reversing the pattern of 2018 through 2024, when new construction carried the higher price in 77 of those 84 months. Kara Ng, a senior economist at the company, said too few shoppers give new construction a look, and that buyers hold the most leverage where builders compete against a crowded field of other sellers. The widest discounts cluster in Sun Belt metros that added housing fastest over the past several years.
