Answer:
$115,302.71
Explanation:
During the first year, the monthly payments were $505.92, and at the end of the year, the principal's balance was $117,494.70.
Then the interest rate increases to 4%, and your monthly payment also increases to $570.72. At the end of year 2, the principal's balance is $115,305.96 (see amortization schedule).
you can determine the monthly payment by using an annuity formula:
original monthly payment = $120,000 / 237.18938 (PV annuity factor, 0.25%, 360 periods) = $505.9248437 ≈ $505.92
adjusted monthly payment (second year) = $117,494.70 / 205.86942 (PV annuity factor, 0.3333%, 348 periods) = $570.7243941 ≈ $570.72
