Policymakers are looking out for indications of what President-elect Donald Trump plans to do to ease housing costs next year. …Trump has spoken frequently of his proposed 60% tariff on goods from China, which he has said would create more manufacturing jobs in the US. …But housing economists and other experts say that could be bad news for building more affordable housing. Selma Hepp, chief economist for CoreLogic, a financial services company, said tariffs are one of her main concerns about the effects of a second Trump term. “One of the biggest concerns is not just lumber [costs], but the overall cost of materials, which have been going up,” Hepp said. Kurt Paulsen, professor of urban planning in the department of planning and landscape architecture at the University of Wisconsin at Madison, said building costs are already high from tariffs on Canadian lumber.
