You purchased a house five years ago and borrowed $400,000 . The loan you used has 300 more monthly payments of $1,686 each, starting next month, to pay off the loan. You can take out a new loan for $355,625 at 2.00% APR compounded monthly , with 300 more payments, starting next month to pay off this new loan. If your investments earn 2.75% APR compounded monthly , how much will you save in present value terms by using the new loan to pay-off the original loan?

There may be rounding in this case, so pick the closest answer.
