Key Points: – New home sales rose 7.4% in March, driven by increased inventory and strong spring demand, especially in the South. – Tariffs on steel and aluminum are expected to raise construction costs, with builders warning of price hikes later in 2025. – Mortgage rates near 7% continue to limit affordability, but buyer activity remains resilient due to builder incentives and more supply. |
New home sales in the U.S. saw a notable boost in March, as builders responded to seasonal demand with more inventory, despite challenges from rising mortgage rates and looming tariff-related cost hikes. The spring buying season got a lift, with the Census Bureau reporting a 7.4% jump in new home sales to a seasonally adjusted annual rate of 724,000 units — handily beating Bloomberg’s forecast of 685,000.
The increase reflects a strong start to what is typically the busiest time of the year for housing. Supply also played a critical role. Inventory rose to 503,000 new homes for sale at the end of March, the highest level since 2007, giving buyers more options amid a tight resale market. This bump in supply helped spur activity, especially in the South, where sales jumped at the fastest pace in nearly four years. The Midwest also saw gains, while activity declined in the West and Northeast.
The housing market’s momentum comes despite ongoing headwinds. Mortgage rates, which hover near 7%, continue to limit affordability for many buyers. These rates follow the trajectory of the 10-year Treasury yield, which has climbed recently amid investor unease about U.S. fiscal policy and political volatility. President Trump’s tariff policies and recent public threats to replace Federal Reserve Chair Jerome Powell have created further market anxiety, causing bond yields to rise and adding pressure on borrowing costs.
High interest rates aren’t the only affordability hurdle. The average new home sales price rose 1% in March to $497,700, while the median price dropped 7.5% to $403,600. This pricing mix suggests more movement in entry-level housing, likely a response to strong demand from first-time buyers and younger households.
Still, looming tariff pressures threaten to raise construction costs and squeeze builder margins. During a recent earnings call, PulteGroup warned that tariffs could increase construction expenses by about 1% in the back half of 2025, translating to an average of $5,000 more per home. CEO Ryan Marshall said the added costs would impact “every single price point and consumer group,” raising concerns about future pricing flexibility.
Taylor Morrison, another major builder, echoed these concerns, forecasting low single-digit housing cost inflation for the year. The culprit: U.S. tariffs on imported steel and aluminum, which are integral to HVAC systems, cable infrastructure, and other construction materials. These added costs are expected to hit hardest in Q4, as builders begin new projects under higher input prices.
To sustain buyer interest, many builders have leaned on incentives — including mortgage rate buydowns and design upgrades — but the staying power of this strategy remains uncertain. As cost pressures grow and rate cuts remain off the table for now, builders may have to choose between profit margins and affordability.
Despite these challenges, the resilience in March’s new home sales shows that the housing market still has underlying strength. For now, buyers appear willing to move forward when supply meets their needs — even in the face of higher borrowing costs.
