21st Century ROAD to Housing Act is Now Law

The July 10, 2026 “Renewing Opportunity in the American Dream to Housing Act” (ROAD to Housing Act, now branded the “21st Century ROAD to Housing Act”) is a large, bipartisan housing package aimed at increasing supply and tweaking federal housing programs. It bundles roughly 40–plus provisions covering housing supply, manufactured housing, homeownership programs, counseling, veterans’ housing, rural preservation and oversight of federal housing agencies.

While the ROAD Act is framed as transformative, it largely just repackages familiar tools, so its long‑run impact on affordability is likely to be incremental and/or nominal.

There was a lot of bipartisan hype and back-slapping after the passage of the ROAD Act, following political drama that kept it from becoming law for unrelated reasons. We kept hearing how terrific it was for the housing market, yet when you look at what it aims to accomplish against the actual issues, it sadly misses the mark. But at least there is recognition of the problem, and some action is being taken. I just wish there was a great understanding of what the problem actually is.

According to the House Financial Services Committee, the new law tries to make it easier to build more homes, cheaper to produce certain types of housing and harder for large investors to outcompete families buying single‑family homes (even though they represent only 1 percent of buyers. The law doesn’t bring money to the table to solve the problem, but it does work within the existing legal and regulatory structure to improve efficiency. All of these items are helpful but not super impactful to the current affordability crisis.

Build more housing by cutting red tape and speeding approvals and environmental reviews for many housing projects.
Support “missing middle,” and manufactured/modular homes to lower construction costs and add units in already developed areas. The act finally eliminates the decades‑old requirement that manufactured homes be built on a steel chassis, and modernizes several rural and preservation programs, which are genuinely useful but only incremental reforms.
Modernize HUD, USDA rural housing and related federal programs so they work faster and better for renters, homeowners, and small landlords.
Unlock more local/private capital for housing through community banks and public‑welfare investment tweaks, without big new federal spending. It authorizes new and expanded grant programs, as well as additional studies and oversight language. These continue the existing template of federal housing policy rather than redesigning core incentives.
Limit very large institutional investors from buying additional single‑family homes so individual buyers have a fairer shot. This was the most touted achievement. The act limits large institutional investors (those with 350+ single‑family homes) from buying additional existing single‑family units, preserving a carve‑out for new construction. However, large‑scale investor purchases are already sharply down, so analysts expect the effect on SFR portfolios and prices to be limited.

Problem between this housing market and the new law

Typically, the relationship between existing inventory and newly constructed inventory shows a dominance of existing inventory. Normally, the national split between the two listing inventory types was somewhere between 90/10 and 85/15 for decades, with existing inventory massively dominating supply. Today it’s a 76/24 split nationally because existing inventory is so unusually low.

Existing U.S. Inventory — 1,570,000 listings 4.6 months of supply — 0.6 percent YoY decline

New Home U.S. Inventory — 496,000 listings 10.3 months of supply — 1.4 percent YoY decline

The ROAD Act’s supply story is almost entirely a new-construction and permitting story (streamlining the process, zoning grants and manufactured housing reform). Its only existing-inventory lever is thinning out corporate-investor competition for homes already on the market, but it doesn’t address the lock-in effect that’s actually suppressing existing listings. The lock-in effect is the disincentive to sell created when a borrower’s existing fixed mortgage rate is significantly below the current market rate for a similar loan.

Hypothetically, if you doubled new construction inventory overnight, it still wouldn’t be enough to solve the affordability problem facing the U.S. housing market.

What was missed in the ROAD Act

The ROAD Act doesn’t touch the biggest driver of tight existing inventory: the mortgage-rate “lock-in effect,” where owners with sub-4 percent rates avoid selling in a 6.5 percent rate world. That would require something like an expanded capital-gains exclusion on home sales, which exists in separate, still-pending bills:

One economic modeling piece from the American Enterprise Institute (AEI) estimates that removing the capital-gains lock-in alone could return 450,000–600,000 homes to the market over a decade, which is the actual key affordability problem.

Since 1997, home sellers can exclude $250,000 (single) or $500,000 (joint) of capital gains from taxes. That threshold was never indexed to inflation. Home prices have risen so much since then that, adjusted for inflation, the exclusion should be roughly $500,000–$700,000 (single) and $1,000,000–$1,400,000 (joint) today. Because it wasn’t updated, many long-time owners, especially seniors, now face a real tax bill if they sell. If an owner holds the home until death instead of selling, their heirs inherit it at current market value, wiping out the capital gain entirely for tax purposes. This creates a strong incentive to just keep the house rather than sell it during retirement. Normally I equate the topic of taxes with watching paint dry. However, in this case, it really matters in the topic of getting more existing listings into the housing market.

Final thoughts

The ROAD to Housing Act adds no new federal spending, so its real impact on affordability will likely be small. Its fixes mostly target new construction, while the actual shortage is in existing homes; the investor curb is largely symbolic since investors are only about 1 percent of buyers. The bill ignores the bigger problem, homeowners with low-rate mortgages who won’t sell because of the “lock-in effect, worsened by a capital-gains tax exclusion frozen since 1997. Fixing that, as separate pending bills propose, could free up 450,000–600,000 homes over a decade. That lock-in is already easing on its own, though. The share of outstanding mortgages under 4 percent has now dropped to 49.9 percent, falling below the 50 percent mark for the first time, down from the 65.1 percent peak in early 2022.

I suspect that housing affordability will remain a challenge over the next seven to 10 years, resolving on its own, unless some substantive reform is introduced.

The actual final thought — ROAD is really a road to nowhere.
