Retirement may look quite different for many Americans who have more mortgage debt than in the past:

Nearly a third of homeowners 65 and older had a mortgage in 2011, up from 22% in 2001, according to an analysis from the Consumer Financial Protection Bureau, using the latest available data.

The debt burden also grew — with older homeowners owing a median of $79,000 in 2011, compared with an inflation-adjusted $43,400 a decade earlier.

For decades, Americans strove hard to pay off their mortgages before retirement, an aspiration that when achieved was celebrated with mortgage-burning parties…

A recent study from Harvard University’s Joint Center for Housing Studies showed that of mortgage holders ages 65 to 79, nearly half spent 30% or more of their income on housing costs. Of mortgage holders 80 or older, 61% pay that amount on housing.

This continues a trend noted last year. This is worth watching as a higher percentage of Americans are older and this particularly affects older residents in more expensive markets where housing options are not as cheap. Homeowners could have several options down the road. First, perhaps they shouldn’t buy homes close to retirement age. Unfortunately, this means they might not be as flexible in searching out new jobs. Second, they may have to sell at retirement and bank that money for future concerns. Yet, even if they can make a good return on selling their home, moving can still be a tough transition (even within a metro area as opposed to moving to significantly cheaper markets). Third, they may have to pursue other living arrangements at retirement such as renting rooms or small apartments in their dwelling to try to make some extra money.
