KB Home Slashes Outlook As Consumer Confidence Wanes and Tariffs Threaten to Hammer The Housing Market

Building costs are stacking up faster than a pile of two-by-fours. On Monday, KB Home slashed its 2025 revenue forecast by $400M, citing slower-than-expected buyer demand as consumer confidence spirals downward. The company’s CEO, Jeff Mezger, noted that the typical early-year acceleration in homebuyer interest has failed to materialize, leaving the industry facing significant headwinds in what should be the bustling spring season.
Foundation for future concerns: The recent tariffs on Mexican and Canadian imports could increase the cost of building an average American home by $7.5K to $10K, as 8% of construction materials are sourced internationally. Industry experts warn that immigration policy changes could further strain construction labor costs, with half of ceiling tile installers and 37% of roofers being undocumented workers, according to John Burns’ assessment. The pain could spread beyond homebuyers to renters, with Green Street’s Cedrik Lachance noting, “The real story on tariffs and immigration is less supply, which is favorable for rent growth.” The combination of affordability challenges, policy uncertainty, and rising costs creates a precarious landscape for homebuilders who are already cautious about starting new projects amid existing inventory gluts.
