Is 30 too old ... for a mortgage?

It may be time to have a re-think! About what? About 30-year fixed rate mortgages.

I know, this is practically sacrosanct territory in this country and questioning it is like questioning, well, God or country.

But there are those who are, in fact, raising some questions about the wisdom of this American institution -- most countries offer only adjustable rate mortgages.

For one thing, the typical American picks up and moves every 5 to 10 years, says theWall Street Journal (subscription required). That makes a 30-year fixed rate mortgage sort of silly on the face of it.
