Step 1 :Calculate the monthly payment for each option using the formula \(P = \frac{{r*PV}}{{1 - (1 + r)^{-n}}}\), where P is the monthly payment, r is the monthly interest rate (annual rate / 12), PV is the present value, or the amount of the loan, and n is the number of payments (years * 12).
Step 2 :For Option 1: \(r = \frac{{8\%}}{{12}} = 0.00666667\), \(PV = \$100,000\), and \(n = 30 * 12 = 360\).
Step 3 :Substitute these values into the formula to get \(P = \frac{{0.00666667 * 100,000}}{{1 - (1 + 0.00666667)^{-360}}} = \$733.76\).
Step 4 :For Option 2: \(r = \frac{{7\%}}{{12}} = 0.00583333\), \(PV = \$100,000\), and \(n = 15 * 12 = 180\).
Step 5 :Substitute these values into the formula to get \(P = \frac{{0.00583333 * 100,000}}{{1 - (1 + 0.00583333)^{-180}}} = \$899.33\).
Step 6 :Calculate the total payment for each option, which is the monthly payment times the number of payments.
Step 7 :For Option 1: \(\$733.76 * 360 = \$264,153.60\).
Step 8 :For Option 2: \(\$899.33 * 180 = \$161,679.40\).
Step 9 :Compare the total payments for the two options. While the monthly payment for Option 2 is higher, the total payment is significantly lower.
Step 10 :\(\boxed{\text{Therefore, Option 2 is the better option, but only if the borrower can afford the higher monthly payments over the entire term of the loan.}}\)
