Builder confidence fell sharply in April as rising costs and economic uncertainty weighed on sentiment heading into the spring buying season. The National Association of Home Builders (NAHB)/Wells Fargo Housing Market Index (HMI) dropped four points to 34 , its lowest level since September 2025. The decline marks a notable setback after modest gains in recent months, with sentiment remaining firmly below the breakeven level of 50 that separates positive from negative market conditions. All three major components of the index moved lower. The gauge of current sales conditions fell four points to 37 , while the index measuring future sales expectations dropped seven points to 42 . The component tracking prospective buyer traffic declined three points to 22 , reflecting continued softness in demand. “Builder sentiment has fallen back in spring as buyers face ongoing elevated interest rates and growing economic uncertainty,” said NAHB Chairman Bill Owens. He added that geopolitical risks and rising energy costs have further dampened confidence and slowed expected momentum in the housing market. NAHB Chief Economist Robert Dietz pointed to increasing pressure from higher fuel prices, noting that a majority of builders are seeing rising material costs as a result. He also highlighted that uncertainty around input costs is making it more difficult for builders to price homes, adding another layer of strain on the market.
