Anthony Cabrera, who started working with a contractor in March to construct the three-bedroom house, was eager to get ahead of a fresh round of tariffs on key building materials and home items that took effect earlier this week. Mr Cabrera had already seen his initial budget of roughly $300,000 balloon to $450,000 as prices for a range of products. …A recent report from Goldman Sachs found that US consumers will shoulder as much as 55% of the cost. It takes time to raise prices on consumers, the economists noted, and US firms will increasingly pass on costs in the coming months. The new tariffs “will create additional headwinds for an already challenged housing market” Buddy Hughes, chairman for the NAHB, said. Affordable housing construction could be hit particularly hard, said Elena Patel, of the Urban-Brookings Tax Policy Center. …Matthew Walsh, at Moody’s Analytics, said that cost uncertainty will be the most immediate effect.
