Elevated interest rates and economic uncertainty sent more home buyers to the sidelines in May as housing affordability conditions remain challenging. Sales of newly built single-family homes declined 13.7% in May, falling back to a seasonally adjusted annual rate of 623,000 according to the US Census Bureau. This was the slowest pace since October of last year, as mortgage rates averaged 6.83% in May. Sales were particularly slow in the South, with the pace of sales down 21% in May. …On a year-to-date basis, new home sales are 3.2% lower thus far in 2025. As a result of slowing home sales conditions, inventory continues to rise, marking an elevated 9.8 months’ supply in May. As estimated by NAHB, total months’ supply, defined as a combination of current new and resale single-family inventory, now stands at 5.2. This is the highest sales-adjusted inventory level since 2015 and will place downward pressure on housing construction starts in the months ahead.
