Housing Shock: Biden Border Wave Blamed

Sign indicating an apartment is available for rent

A quiet working paper from the Dallas Federal Reserve just put hard numbers on something many homeowners have felt in their gut for years: when Washington throws the border wide open, your house becomes someone else’s lottery ticket and your kid’s starter home drifts out of reach.

Story Snapshot

Dallas Federal Reserve economists found Biden-era unauthorized immigration explained about 30% of home price growth and 20% of rent growth from 2021 to 2024 at the average metro.^[5]
A one percent rise in unauthorized immigrant workers boosted local home prices by roughly 2.2% and rents by 1.4%, with almost no increase in new housing supply.^[5]
The study ties these jumps to a pure demand shock hitting a housing market where supply was already locked down by zoning and red tape.^[4]
Critics argue the impact on the overall price level was smaller and say long-term supply shortages, not immigration, remain the main villain.^[2]^[7]

The Federal Reserve quietly confirms the border–housing price link

Two Federal Reserve Bank of Dallas economists dug into newly available federal immigration records and local housing data for the boom window from early 2021 through early 2024.^[4] They tracked flows of unauthorized workers into 721 local labor markets and then matched those inflows to changes in jobs, wages, home prices, rents, and new building permits.^[5] The question they asked was simple but explosive: when millions of extra people show up needing housing fast, who pays the bill?

The answer was blunt. The authors found that a one percent increase in unauthorized immigrant workers, as a share of the local workforce, raised local house prices by about 2.2 percent and rents by 1.4 percent during the period studied.^[5] Local employment also rose one-for-one with the new workers, and average wages did not fall in a clear way.^[4] More people were working, but the housing stock barely budged. The extra demand piled straight into prices instead of new homes.

How much of the 2021–2024 housing boom came from illegal migration?

Anyone who tried to buy a house after 2020 remembers the shock. Prices jumped more than 20 percent nationwide while mortgage rates whipsawed. The Dallas Fed paper does not say immigration caused the whole surge. It does something more focused and more useful. It runs the numbers and estimates that unauthorized immigrant worker flows explain roughly 30 percent of total home price growth and 20 percent of rent growth between March 2021 and March 2024 in the average metro area.^[5]

That 30 percent figure has become the lightning rod. Conservative outlets highlight it as proof that “open border” policy has real costs for middle-class families.^[1] Some analysts on the left fire back that the actual contribution to the typical home’s price level was under three percent, because the 30 percent number refers to the share of the increase, not the final sticker price.^[2] Both statements can be true. The key point for a buyer, though, is this: a policy shock in Washington did not just add workers; it also tacked on several extra percentage points to the bidding war for every starter home in your town.

Demand shock meets a broken housing supply system

The most important sentence in the Dallas Fed paper may not be the 30 percent line at all. It is the finding that these immigration flows raised prices and rents “without expanding housing supply,” which the authors say fits a classic demand shock hitting a market where supply cannot move much in the short run.^[4] That reads like a quiet indictment of decades of local zoning fights, permit delays, and environmental reviews that stopped builders from adding enough homes even before the border surge.

Plenty of prior research backs this up. Studies going back to the mid-2000s found that a one percent jump in immigrant share often raises local prices or rents by about one percent, and sometimes more, when builders cannot respond quickly.^[15] Other work finds that immigrants add trillions in housing wealth by stabilizing neighborhoods and filling homes that might otherwise sit empty.^[16] Put together, the pattern matches common sense and standard economics: when supply is stuck, any big increase in population — whether from college graduates, investors, or migrants — pushes up prices. Immigration is not the only driver, but it is part of the load-bearing wall.

Where critics push back, and what they miss

Some housing researchers and media outlets insist the Dallas Fed study overstates the impact of unauthorized immigration and argue that supply shortages and low interest rates remain the main story.^[7] Their strongest factual point is that, in dollar terms, the added pressure on the median home’s price appears modest compared with the full 22 percent run-up. They also note that immigration flows have already slowed sharply since mid-2024, while affordability is still terrible.^[6]^[7]

🚨NEW: A Dallas Fed study says Biden-era immigration from 2021-2024 added to U.S. housing demand.

Per the paper: A 1% rise in unauthorized immigrant workers = ~2.2% higher home prices & ~1.4% higher rents. They also say limited housing supply was a major factor too.

Those are fair cautions, but they do not erase the core finding. The Dallas Fed authors used rich individual-level immigration records that most earlier studies lacked and exploited differences across local markets to get closer to cause, not just correlation.^[4] So far, critics have not published a detailed re-analysis of that data. They rely instead on broad claims about supply and ignore the uncomfortable fact that, in a frozen supply environment, any extra demand — especially a policy-driven wave of unauthorized workers — lands hardest on working- and middle-class Americans who do not get subsidies or corporate lawyers.

What this means for voters who care about both borders and paychecks

For a voter who values secure borders, tight labor markets, and basic fairness, the Dallas Fed paper does not say “shut immigration down.” It says something more grounded: you cannot run record levels of unauthorized migration into a housing market already strangled by regulation and then act shocked when families are priced out. An honest policy debate would tackle both sides at once. Fix the border so inflows are legal, predictable, and tied to the country’s real capacity. At the same time, rip out the local barriers that keep builders from adding supply when demand jumps.

That balanced approach lines up with common sense and the data. Legal, measured immigration can boost growth and revive struggling towns. Lawless border surges, dropped on top of locked-down housing markets, act like a hidden tax on every young family trying to buy their first home. The Dallas Fed did not write a campaign ad; it wrote an economic warning label. The question now is whether anyone in power will read it all the way to the end.
