A 4-Million-Home Shortage, One Unsigned Bill, and What Sellers Should Do Now

A bipartisan housing bill that Congress passed with rare cross-aisle enthusiasm is sitting on President Donald Trump's desk unsigned. The 21st Century Road to Housing Act — described by Trump himself as the most comprehensive housing legislation in U.S. history — faces a Friday deadline to either be signed, vetoed, or become law without presidential action. For the millions of homeowners weighing whether to sell in 2026, that limbo is more than political theater. It reflects the same calculation sellers have been stuck inside for two years: relief is close enough to name, but too far away to price into your decision.

The Shortage Is Real, and This Bill Won't Fix It Overnight

The structural backdrop behind the legislation is not in dispute. The U.S. housing market is currently short an estimated 4.03 million homes. Transaction volume sits near historic lows. The share of adults living with parents rather than forming their own households has hit record levels. The Road to Housing Act is designed to chip away at those barriers — through measures that would support more multifamily construction, infill development, manufactured housing, and renovation of existing stock. One provision targeting manufactured housing regulations alone is projected to reduce per-unit production costs by $5,000 to $10,000.

But the timeline for any of that to reach your neighborhood is long. Dennis Shea, executive vice president and chair of the J. Ronald Terwilliger Center for Housing Policy, told Realtor.com News that the signing delay itself won't matter much operationally, because most provisions require months of implementation, appropriations by Congress, local government participation, and private-sector follow-through before a single new unit comes to market. There is also no published estimate yet of how many total homes the final package will add, or how significantly — or when — it will move prices in specific markets.

In other words: this bill is a foundation, not a flood. The supply relief it promises will arrive gradually, over years, not quarters.

What List Prices and Rate Lock Are Already Telling You

While Washington deliberates, the current data is giving sellers a clear-eyed picture of where demand stands. List prices posted their steepest annual decline in nine years in May 2026, then fell 2.5% year over year in June. Buyer hesitation is structural: elevated mortgage rates, insurance costs that routinely surprise buyers on the high side, and property taxes that reset to full assessed value at the point of sale are combining to push qualified buyers back to the sidelines.

The rate-lock effect amplifies the inventory problem from the supply side. Roughly 78% of outstanding U.S. mortgages carry rates below 6%, and just over half sit at or below 4%. Homeowners with those rates have a powerful financial reason not to move — and they're acting on it. ATTOM data shows that sellers who transacted in late 2025 had owned their homes for an average of 8.6 years, the longest median tenure recorded since at least 2000. The homes that buyers actually want — turnkey, well-maintained, in established communities at manageable carrying costs — are precisely the ones that aren't coming to market.

What This Means If You're Deciding Whether to List

The current environment does not uniformly favor waiting or moving. It depends on what you own, where it is, and what your alternatives look like.

If you own the inventory everyone wants, your leverage is real — but limited. Updated, well-maintained single-family homes in desirable communities remain the tightest product category in most markets. Buyers are waiting specifically for homes like yours. That scarcity has pricing power, even in a broader buyer's market. But that power is being competed against by buyer math: their all-in monthly cost including insurance and property tax is what's breaking deals, not purchase price alone. Price your home so that the total carrying cost clears their budget, not just so the sticker looks competitive.

If your home needs work or sits in a market with softening prices, waiting for the bill to change things is not a strategy. The Road to Housing Act is aimed at long-run supply, not near-term demand. Nothing in this legislation will meaningfully increase buyer appetite in the next 90 days. If you're planning to sell in the next two years, the market you see today — declining list prices, qualified buyers pausing, elevated inventory in some segments — is the market you're pricing into.

On timeline: a Friday deadline means policy clarity could arrive within days. Whether Trump signs, vetoes, or allows the bill to become law without his signature, the uncertainty resolves soon. That won't change your market tomorrow, but it will change the narrative around housing policy heading into the second half of 2026. A signed bill gives sellers and buyers a clearer long-term picture; a veto restarts the political debate and likely extends uncertainty further.

On net proceeds: the 2.5% year-over-year drop in list prices is a real number to work with. If you were underwriting your move based on peak 2024 pricing assumptions, revise those projections now. In many markets, sellers are netting less per square foot than they expected 18 months ago. That doesn't mean selling is the wrong call — but it means your net proceeds number needs to be built on current comps, not optimistic assumptions that relief legislation will lift prices before you close.

If you want a specific number to anchor your thinking, an instant-offer estimate can give you a baseline to compare against the open market — without committing to either path.

The housing shortage is real and documented. The legislation intended to address it is substantive and bipartisan. But the gap between policy passage and felt market impact is measured in years, not weeks. Sellers who make decisions based on what the market is doing now — rather than what Washington is about to fix — will be better positioned regardless of what happens at the White House this week.
