If influx of illegals cause housing costs to increase then mass deportations cause housing costs to fall. Right?
Affordability is the new buzz word. President Trump benefited from President Biden’s mismanagement of the economy and now the pundits are saying that the recent victories by democrats in New Jersey, New York, Virginia and Georgia are a product of Trump’s mismanagement of the economy perpetuating the crisis of affordability. While the term applies to a wide variety of prices a good deal of recent conversations has focused on housing affordability. When Biden was president and Trump was on the campaign trail, Trump pointed the blame for the high cost of housing on the surge of illegal immigrants during the Biden years. Pointing out that an average of 2.5 million illegals per year had come into the country, Trump said that deporting millions of illegals would positively impact the U.S. housing market by freeing homes for Americans and boosting inventory across the country. Has it?
Now elected, his vice president, JD Vance has put the high cost of housing squarely on the influx of illegals. Vance said “A lot of young people are saying, housing is way too expensive. Why is that? Because we flooded the country with 30 million illegals who are taking houses that ought, by right, to go to American citizens.”
You know, it sounds reasonable. But as my father used to say to me “That sounds good – if you are interested in sounds.” It’s an empirical question. One would think that the areas where the illegals settled would have seen a surge in prices greater than the country at large. Although Vance attributes the high cost of housing to the illegals, one would think the impact would be on the rental market rather than the market for homes.
Shouldn’t prices be higher in areas with more illegals? Fed governor Michelle Bowman said “Given the current low inventory of affordable housing, the inflow of new immigrants to some geographic areas could result in upward pressure on rents.” There are empirical questions that need to be researched regarding whether the low inventory and resulting high prices are due to the illegals. Studies of the question should look at supply factors as well as demand.
Here is what two different studies have found. One study looked at the housing market and finds that there is “no significant relationship between unauthorized immigrants and general house price growth for each state in the U.S.” The study entitled “Beyond the hype: Unauthorized immigrants and the myth of rising house prices.”
https://www.sciencedirect.com/science/article/abs/pii/S1544612325001503
Here is its abstract:
“A recent social and economic issue has addressed public attention: whether unauthorized immigrants drive up local housing prices. This study focuses on this issue and finds no significant relationship between unauthorized immigrants and general house price growth for each state in the U.S. We prove the robustness of this insignificance by addressing the endogeneity issue and applying alternative variables to measure house prices and the number of unauthorized immigrants. This study highlights the importance of ensuring political and public discourse based on evidence and rigorous analysis rather than oversimplified narratives.”
Another study looked at the growth in rents and home prices and data indicate that the timing of the recent immigration surge does not align with the significant increases in rents and home prices observed at the onset of the pandemic. While immigrants contribute to household growth, the surge in housing demand during the pandemic was primarily driven by native-born households amid a constrained housing supply.

I find both studies interesting although I would have modelled the research a bit differently. I would have concentrated on the rental market where one writer notes “For renters, things have gotten less bad. The rate of increase in
rents has flattened in most local markets and has even declined slightly in some areas. This is, in part, because the rent growth was so high over mid-2021 through mid-2023 that there was perhaps nowhere to go but down in terms of the rate of increase. But it also appears to be the case that a relatively large supply of new apartment construction coming online has moderated rent growth, providing some critical relief to cost-burdened renters. That said, a record number of renters are experiencing housing cost burden—defined as spending more than 30 percent of gross income on housing costs.”
Experts say that Illegals primarily rent rather than buy because of limitations on buying because of their legal status. Illegals are also more likely to double up or live with extended family members or nonrelatives compared to U.S.-born households. Again, this means that the primary impact would be in the rental market rather than the home purchase area.
Also have the mass deportations lowered rental and housing costs? Again this is an empirical question. Trump claimed that it would but so far the evidence is contrary. Some observers find the opposite has happened. Here is what some researchers have found “We’re able to show that when you increase immigration enforcement, you do in fact generate a reduction in the number of individuals who are supplying labor to the construction industry in a given county. We show that those reductions in workforce are associated with a large
decline in homebuilding.” Mass deportations, the researchers concluded, cause reductions in the construction sector’s workforce and residential homebuilding, decreasing construction and increasing home prices. Oops.
On the other side are two studies that make the argument that the influx of illegals has caused the price of housing to rise. One is from the website “Populist Policy” entitled “How illegal migrants drive up housing costs.” https://populistpolicy.org/how-illegal-migrants-drive-up-housing-costs/
The other is J.P. Morgan’s “The outlook for the US housing market in 2025 which has the sole statement “It’s estimated that there are 11.2 million undocumented immigrants in the U.S., and that number may be higher. This could be ramping up housing demand more than figures suggest, resulting in a shortage of stock.”
In sum, it appears that the influx of illegals did not increase home prices due to their occupying rental homes. However, mass deportations caused a restriction in construction decreasing the construction of new housing and contributed to the rise in home prices. As to the rental market, I withhold judgment. The studies’ specifications do not actually address this question properly. Yet
while illegals may play some role in affecting housing prices, the majority of the reasons that there are increases in housing are other factors separate from the aliens that are due to the actions of governments at all levels. I will post another piece going into details those reasons for the high housing prices.
