Answer:
$1,680
Explanation:
during the first 5 years, the monthly payment will = $2,816.18
I prepared an amortization schedule. After the 60th payment, the principal owed = $335,580
the new monthly payment considering that the interest rate fell significantly to 3.5% = $1,680
calculation to determine the monthly payment:
present value of the loan = monthly payment x PVIFA
monthly payment = present value / PVIFA
PVIFA, 0.29167%, 300 periods = 199.7501
monthly payment = $335,580 / 199.7501 = $1,680
