2. "With mortgage rates currently around 3-4% I wouldn't pay it off." In response to In response to 0 Fri Mar-20-15 12:40 PM by soulfunk
Maybe pay at an accelerated rate and invest the rest. Depending on how much time is left on your mortgage you could refi from a 30 year into a 15 year which would typically give you an even lower rate.
But if you can invest and make more than that 3-4% you're paying in interest on the mortgage, then investing makes more sense.
