Bob Hagerty blogs about Patrick Lawyer on Fixed Rate Mortgages:

He writes, in part:

Allotted only about 10 minutes to share his vision, Mr. Lawler....first made the obligatory statement that he was expressing his own views and not those of his federal agency. Yeah, right, I thought, and reached for my triple espresso.

But then Mr. Lawler launched a frontal assault on the most sacred element in U.S. housing-policy dogma: the 30-year fixed-rate mortgage loan, providing the right to refinance at any time, with no prepayment penalty. If more members of the audience had been fully awake at this moment, I feel sure that their gasps would have been audible.

Now, Americans are very attached to their 30-year fixed-rate freely prepayable mortgages. They like not having to fuss about the possibility of 28% interest rates in 2032, even though most of us will move or die long before then. They love to refinance every time rates drop and then brag to their neighbors about how much they are saving per month.

What they don’t stop to realize often enough is that they are paying a very large price for that privilege– twice.

The context is important.  One of the reasons the 30 year fixed rate mortgage is ubiquitous is the United States may be the existence of Fannie and Freddie.  If we do away with FF, we may also do away with the 30-year fixed rate mortgage.  So let me defend the 30-year fixed a bit with something I wrote about 3 years ago:

The problem with advising people to use adjustable rate mortgages, however, is that ARMs give households liabilities that have short duration--that is, liabilities whose market value remains close to face value at all times. This is because the rates on ARMs by definition change to meet market rates on a regular basis. Houses, on the other hand, are assets with lots of duration. The services they give to homeowners (shelter and a set of amenities) is pretty much invariant to market conditions. Consequently, house values change with market conditions, such as changing interest rates.

Good financial management practice suggests that to minimize risk, the duration of of assets and liabilities for any institution, including households, should be matched. In the case of houses, this means that households looking to minimize risk should use a fixed rate mortgage to finance their house. There are exceptions--if one buys a house and expects to sell it in five years, a five year ARM makes lots of sense, because the duration of the asset (housing services over five years) and the liability would match.

This is not to say there is anything wrong per se with people getting ARMS, so long as they explicitly understand the risk embedded in them. But a principle I have been pushing for years is that if people can't afford a house with a fixed-rate mortgage, they probably shouldn't buy a house. It is one thing to have the option of the FRM, and then decide to take the risk of the ARM anyway. One of the nice things about the United States is that FRMs are easy to come by--this is not true in most countries around the world. It is something else to be forced into taking a risk in order to buy. Under these circumstances, buying probably isn't worth it.
