is an interest-only mortgage a bad idea?
user
if you took a fixed loan, but paid it off at the accelerated rate, you would ultimately pay less total dollars in interest. so compare the actual amount paid in interest over the course of the loan rather than the interest rate itself.  that should be your answer. also, plan on failing in your plan to pay it off and see how that will affect you.
