in buyinbg a hone using prepayment verses investment what are the opportunity cost considerations if i was to pay $50.00 extra a month? the way i see this i am oweing more at the end of my loan term.

The sooner you pay off your home mortgage the better off you are. Paying additional money each month on your mortgage also lowers the interest you pay. Owning your home free and clear should be your first financial task.
