If you continue making the same payment that you are making now, approx $2250mo.
Your $22,000 ‘investment’ will save you $144,000 (GUARANTEED) in interest payments over the life of the loan and you will pay the loan off in 23yrs and 2months rather than 28.5 years.

If you save the $300 every month and just make the lower minimum payment each month, the $22,000 investment will save you about $114,000 in interest over 30yrs QED
