Final answer:
The monthly mortgage payment for the house will be approximately $1,013.37.
Step-by-step explanation:
To calculate the monthly mortgage payment, we can use the formula:
M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ]
Where:
M = monthly mortgage payment
P = loan amount - down payment
i = monthly interest rate (APR divided by 12)
n = total number of monthly payments (30 years multiplied by 12)
In this case, the loan amount is $250,000 - $50,000 (down payment) = $200,000, the monthly interest rate is 4.5% divided by 12 = 0.375%, and the total number of monthly payments is 30 years multiplied by 12 = 360 months.
Plugging these values into the formula:
M = $200,000 [ 0.00375(1 + 0.00375)^360 ] / [ (1 + 0.00375)^360 - 1 ]
Calculating this will give us a monthly mortgage payment of approximately $1,013.37.
