The US Senate has passed a housing bill, the 21st Century ROAD to Housing Act, which includes over 40 provisions aimed at reducing housing costs and creating low-cost options for homeownership. The bill allows manufactured homes to be assembled without a permanent chassis, increases federal loan limits for buyers, and relaxes zoning regulations on where they can be sited. These changes are expected to significantly increase housing supply and reduce stigma around low-priced "mobile homes." However, the bill faces an uphill battle over whether large institutional investors should continue buying and renting homes, a practice criticized by both Sen. Elizabeth Warren and President Donald Trump. The National Association of Realtors has expressed support for the bill, which streamlines federal processes to build more homes.
