You notice he doesn't give the cost per month of the lesser year loans. If you are on a fixed income, you look for the cheapest outlay of income. (Fixed income could be a job with no increase for several years. Or no overtime pay. And if you base your payment on a job that has overtime and it is cut out, you lose.) And what about the family that has two bread winners and one loses their job?
ALL facts must be looked at. Not just the payout over the term.
Also, I think that the latest poll sowed that most people move every seven years. Most to a bigger house, with a bigger payment.
