JD Vance says immigration is to blame for high housing costs. Here's what the experts say.

High housing costs are a serious pain point for millions of Americans, with many shut out of the real estate market by record-high home prices and others plagued by spiraling rents. During Tuesday's vice presidential debate, Sen. JD Vance pointed to what he views as a major cause of the affordability crisis: immigration. 

"[Y]ou have got housing that is totally unaffordable because we brought in millions of illegal immigrants to compete with Americans for scarce homes," Vance said in the debate with his Democratic rival and Vice President Kamala Harris' running mate, Minnesota Gov. Tim Walz.
