HIGHER EDUCATION BUBBLE UPDATE: Student debt may hurt housing recovery by hampering first-time buyers.

The growing student loan burden carried by millions of Americans threatens to undermine the housing recovery’s momentum by discouraging, or even blocking, a generation of potential buyers from purchasing their first homes.

Recent improvements in the housing market have been fueled largely by investors who snapped up homes in the past few years. But that demand is waning as prices climb and mortgage rates rise. An analysis by the Mortgage Bankers Association found that loan applications for home purchases have slipped nearly 20 percent in the past four months compared with the same period a year earlier.

First-time buyers, the bedrock of the housing market, are not stepping up to fill the void. They have accounted for nearly a third of home purchases over the past year, well below the historical norm, industry figures show. The trend has alarmed some housing experts, who suspect that student loan debt is partly to blame. That debt has tripled from a decade earlier, to more than $1 trillion, while wages for young college graduates have dropped.

The fear is that many young adults can no longer save for a down payment or qualify for a mortgage, impeding the housing market and the overall economy, which relies heavily on the housing sector for growth, regulators and mortgage industry experts said.

Do tell. Someone should write a book on this phenomenon.
