Builders completed single-family homes faster in 2025, but the improvement came with an important caveat: Homes took longer to sell.
According to NAHB’s latest analysis of Census Bureau data, the average single-family home took 8.8 months from authorization to completion, down from the previous three years. Homes built for sale moved even faster, averaging 7.4 months.
That should be good news for builders. Shorter construction timelines can reduce carrying costs, limit exposure to price increases, and allow capital to move into the next project sooner.
But only if the finished home sells.
In 2025, 31.5% of homes built for sale sold after completion, up from 27% in 2024. Meanwhile, the share sold before construction or while underway declined. Another 8.3% remained unsold at the time of the survey.
That means some of the time builders gained during construction may have been lost after completion, while interest, taxes, insurance, and maintenance continued accumulating.
The builder insight is straightforward: Construction velocity and capital velocity are not the same thing.
In a slower sales environment, builders need to evaluate the full cycle—from acquiring the lot to collecting the sale proceeds. Finishing faster still matters, but starts, pricing, and financing must align with realistic absorption so completed inventory doesn’t become trapped capital.
