15 vs 30 Year Mortgage - for Windows 3.1 Description:

Do you really think you're saving money with a 15 year fixed rate
mortgage rather than one with a 30 year term. This program may
change your mind. The basic premise of this evaluation is that if
the buyer could afford the monthly payments for the shorter term
(and would invest thedifference in monthly payments according to
the instructions), at certain rates of return on the investment it
would be more advantageous to obtain the 30 year mortgage.
