President Trump’s tariffs could increase material costs for the average new home by as much as $10,000, according to the National Association of Home Builders. The trade group said it has received anecdotal reports from members that Trump’s plan would raise material prices by between $7,500 and $10,000 for the average new single-family home. …The NAHB said softwood lumber is mainly sourced from Canada, while gypsum, a component of drywall, comes primarily from Mexico. Other materials like steel and aluminum — in addition to completed home appliances — are imported to the U.S. from China, the group said. An implementation of the 25% tariff on Canada and Mexico as previously laid out by Trump would raise total costs for imported construction materials by more than $3 billion, according to the NAHB.
