First-time homebuyers are having a difficult time participating in the real estate market:

Just 33% of primary residences sold this year were purchased by first-time buyers, down from 38% last year to the lowest level since 1987, the National Association of Realtors reported Monday.

The NAR says that the first-time-buyer share of home sales has typically hovered around 40% since 1981.

The headwinds facing young buyers are well known: higher student debt, rising rents and a weaker job market have made it harder for would-be buyers to save for a down payment and qualify for a mortgage, particularly in a lending environment where banks are much less willing to overlook credit blemishes or spotty incomes…

The NAR survey also found that people are staying in their homes longer than in the past. The median age of tenure–that is, the amount of time a typical homeowner stays in one house–rose to 10 years in the most recent survey, from six years in 2007.

This isn’t just about not having enough cheaper homes at the lower end of the market; this is also about getting people into the patterns of buying homes and then moving to bigger homes as their families and incomes grow. While there is still evidence that many young Americans want to purchase homes, being able to actually participate is a crucial first step.
