Which Mortgage Rate?

A recent study by Moshe Arye Milevsky examined the better choice between a fixed-rate mortgage or a floating-rate mortgage (changes monthly based on the prime lending rate).
Suppose you are amortizing your payments over 15 years. Regardless of the 15-year period you were paying the mortgage payments (during the past 50 years), the floating-rate mortgage came out ahead.
Therefore, if you can handle the fluctuating payments, it appears that the floating rate may be your best bet.
