This is an argument that economists have widely trumpeted as a major benefit of acting on immigration. But few politicians have been talking about it until the President raised the issue this week during a visit to Arizona. The White House released some data that is certainly bolsters the claim. From The Hill:

According to data provided by the White House, immigrants accounted for almost 40 percent of new homeowners between 2000 and 2010. In California, immigrants accounted for more than 80 percent of the growth in homeowners, while in New York, more than two-thirds of new buyers were immigrants.

In Southern states like Georgia and North Carolina, immigrants made up more than a quarter of new homeowners, according to the White House.
