Part of the reason is all people want to hear is the rate, they make the decision based on what the rate is they do not look at the big picture.
Up until the last 12 months or so people would hear the lower rate and say that is what I want.
An adjustable rate mortgage is good for a couple of reasons;
1) if you plan on staying in the home for 3 years then a 5 year arm would be good for you.
2) If you know that you will definately refinance before the loan starts to adjust then it would be a good idea.
the other problem lower rates on the arms let people buy bigger homes then what they could afford. there is a program out there called an option arm which the monthly payment was based on 2% but you accrued interest at 6%. You had 4 payment options and everyone was making the smaller payment which zapped everyones equity.
