Answer:
$662.63
Explanation:
Cost of mortgage = $120,000
Interest rate of first period = 5.25%
The loan was amortized over 30 years.
The interest rate at the end of the initial loan period = 6.75%
Margin = 1.5%
The loan was amortized for over (30*12) months
= 360 months
The interest rate of the first period per month = 5.25% / 12
= 0.0525/12
= 0.004375
Payment for monthly mortgage =
(120000(0.004375)) / 1 - (1 + 0.004375)^-360
= 525 / 1 - (1.004375)^-360
= 525 / (1 - 0.2077)
= 525 /0.7923
= 662.63
= $662.63
