Patrick Brenner, Southwest Public Policy Institute President, thinks these have been terrible ideas. I disagree. Central to his thesis this:

The 30-year mortgage locked families into a lifetime of interest payments that cost the borrower far more than the original price.

However, he never mentions a Critical Item that also obtained throughout his period of interest, the post-WWII mobility, both geographically and economically upward, of the American working force/homeowner population.

Two personal examples illustrate, and I claim our examples are typical, not unusual.

When my wife and I were starting out, as Lieutenants in the USAF, we were able to buy our first house courtesy of one of those “dangerous” shorter term balloon payment loans. We were highly mobile as USAF officers, but that mobility, as I claim, wasn’t unusual—the civilian work force also was highly mobile, and that mobility allowed homeowners to sell their homes, pursuant to their mobility, before the balloon came due, and buy another home in their new location, now with a variable rate loan (fixed for a period of years, then floating with the market), 15-year fixed mortgage, or an evil 30-year mortgage, with interest rates favoring the variable rate and the 30-year. Again, mobility allowed most homeowners to sell their homes before the variable rate reset, along with selling their 30-year mortgaged homes long before being “locked in for life.”

It also was the case that many of these balloon mortgage homeowners refinanced into a new variable rate loan or into a 15-year or 30-year mortgage. Banks expected these sorts of refinances and smoothed the path.

Many years later, as my wife and I were long established civilians and approaching retirement, we bought our current house with a 30-year mortgage. We’ve since refinanced that mortgage a number of times as interest rates went down, and currently have a monthly payment a bit over half that original payment.

So much for ever being locked in for life with a high-rate mortgage. With that mobility, very few homeowners actually paid more in aggregated principal and interest than the value of their homes—they refinanced down, or they sold and moved on.

The only thing in the way now is a greatly reduced mobility in our homeowner population. There are a number of reasons for that reduction in mobility, but the key here is that reduced mobility. Being “stuck” in some way with a 30-year mortgage is a symptom of relative immobility, not a cause of affordability. That immobility also contributes heavily to the lack of houses on the market while demand for homeownership remains high—that’s excess elevated pricing for homes.
