Despite Their Higher Education, Millennials Still Aren't Buying Homes - CityLab:
"A bachelor’s degree is not a requirement for homeownership, but it is starting to look like one. As household incomes are increasingly linked to educational attainment, so is homeownership status. At the same time, higher education can be a temporary barrier to homeownership. This paradox might be the driving factor of the U.S. housing market today, which is still slow to grow even despite a strong recovery"
I've seen several studies on this. The growing income gap between college graduates and people without degrees means that graduates are more likely to be able to buy a home. But, because it takes four years to get the degree, the college graduates get married and/or enter the housing market later. The often-repeated claim that college graduates can't afford homes because of student loans doesn't stand up to empirical analysis. But part of this is on the supply side. The real estate development industry is not building many starter homes at present, in large part because of the higher lending standards that still prevail.
