The U.S. Senate has passed the 21st Century ROAD to Housing Act, a sweeping bipartisan housing reform package aimed at boosting housing supply and improving affordability, setting up a final round of negotiations over a bill that could reshape federal housing policy.
The Senate approved the legislation in an 89–10 vote on Thursday. Lawmakers must now reconcile differences between the bills before a final version can move to the president’s desk.
Industry leaders say the legislation represents one of the most significant federal housing policy efforts in years as policymakers try to close a housing supply gap that economists and housing groups frequently estimate at several million homes nationwide.
Mortgage Industry Welcomes Supply Measures
Mortgage industry groups largely welcomed the Senate’s move, citing provisions intended to encourage housing development and expand access to mortgage credit.
“MBA supported the underlying House and Senate housing proposals that formed the basis for this bipartisan package and appreciates policymakers’ continued focus on meaningful solutions to address our nation’s housing supply and affordability challenges,” Mortgage Bankers Association President and CEO Bob Broeksmit, CMB, said after the vote.
Broeksmit said several provisions in the bill could help expand housing supply and improve access to homeownership.
Investor Ban Sparks Industry Concerns
While the bill includes numerous supply-focused provisions, one of the most controversial sections targets institutional investors in single-family housing.
As written, the legislation would prevent firms that own more than 350 single-family homes from purchasing additional properties.
The policy is intended to curb corporate ownership of homes and increase opportunities for individual buyers, an issue that has drawn increasing attention from lawmakers following the rise of institutional landlords in the years after the 2008 financial crisis.
But mortgage and housing industry groups warn the provision could have unintended consequences.
The bill would also require certain investors to sell rental homes within seven years, a provision critics say could disrupt financing for build-to-rent housing communities, which have expanded in recent years as demand for rental housing has grown.
MBA said the restrictions could limit capital flowing into rental housing development and reduce the availability of new housing supply.
FHA Loan Limit Language Raises Red Flags
The Mortgage Bankers Association also raised concerns about language that affects Federal Housing Administration multifamily loan limits.
In a letter sent on March 11 to Senate leadership and members of the Senate Banking Committee, the group warned that drafting errors in the legislation could unintentionally require the FHA to reduce multifamily loan limits below levels calculated under current law.
The limits have not been updated since 2003, and the original intent of the provision was to modernize them to better reflect rising construction costs.
MBA said lowering the limits could constrain financing for new rental housing projects at a time when policymakers are trying to expand housing supply.
Room For Improvement
Other mortgage industry leaders struck a similar tone following the Senate vote — praising the bill’s direction while urging lawmakers to refine key provisions.
“There is an incredible amount to like in this bill, from the modernized treatment of manufactured housing to the focus on small-dollar mortgages,” said Isaac Boltansky, head of public policy at Pennymac.
“Nevertheless, there is clearly room for improvement in both certain technical matters and the SFR section. To truly move the needle, we should ensure the final language doesn't create unintended headwinds for supply, consumers, or lenders.”
What It Could Mean
For mortgage lenders and originators, the legislation touches several areas of the housing finance system — from small-balance lending and appraisal practices to rental housing investment and factory-built housing — with potential implications for both loan production and housing supply.
- Expansion Of Small-Dollar Mortgages
The bill includes provisions aimed at expanding small-dollar mortgage lending, a segment many lenders avoid due to compliance costs relative to loan size. If regulatory burdens are reduced, originators could find new opportunities serving borrowers purchasing lower-priced homes, particularly in rural and older housing markets. - Support For Manufactured And Modular Housing
The legislation emphasizes manufactured and modular housing, which policymakers increasingly view as a scalable solution to the housing shortage. Expanded financing pathways could create new lending opportunities tied to factory-built housing developments. - Institutional Investor Restrictions
The bill would prevent companies that own more than 350 single-family homes from purchasing additional properties and could require certain investor-owned rental homes to be sold within seven years. Supporters say the move could open homes to buyers, while critics warn it may reduce capital for build-to-rent communities. - Potential Impact On Rental Housing Development
Language affecting FHA multifamily loan limits has raised concerns among mortgage industry groups. The Mortgage Bankers Association says drafting issues could unintentionally reduce loan limits and constrain financing for new rental housing development. - Rural Housing And USDA Loan Reforms
The bill includes reforms to the USDA Rural Housing Service, including technology upgrades and provisions allowing certain USDA mortgages to become assumable. It also expands financing options for accessory dwelling units (ADUs) in rural areas. - Appraisal Modernization
Federal housing agencies would be directed to implement reconsideration-of-value (ROV) processes through regulation, allowing borrowers to challenge appraisal values without imposing new statutory liability on lenders. - A Broader Push To Increase Housing Supply
More broadly, the legislation reflects growing bipartisan focus on housing supply as the primary solution to affordability challenges. Increased home construction could translate into expanded lending opportunities for mortgage originators.
What Happens Next
The legislation still faces several hurdles before becoming law.
Lawmakers must reconcile differences between the Senate and House versions of the bill before any final legislation can be sent to Washington. That process could result in revisions to several controversial provisions, including the proposed limits on institutional investors purchasing single-family homes and language affecting Federal Housing Administration multifamily loan limits.
Mortgage industry groups say they will continue working with lawmakers as negotiations move forward.
More broadly, the legislation reflects a growing shift in Washington toward supply-side housing policy as a primary solution to affordability challenges. Industry leaders say that if regulatory barriers are reduced and housing construction accelerates, the result could translate into increased mortgage origination opportunities tied to new home construction and expanded housing inventory.
“For these reasons, MBA urges Senate leaders and the administration to work with the House to address these provisions before the legislation moves any further,” Broeksmit said. “The goal should be clear: a final package that puts the country on a path to increased affordability, lower operational costs, less red tape, and more housing, not less.”
