Final answer:
The lender will disburse $81,400. The APR for the borrower is 6.17%. The effective interest rate is -6.55% if the loan is paid off after five years.
Step-by-step explanation:
To determine the disbursement amount, we subtract the loan fee from the loan amount. So, $85,000 - $3,600 = $81,400. The lender will actually disburse $81,400.
To find the APR, we need to calculate the total interest paid over the 30-year term. The monthly payment can be calculated using the formula: P = (r * PV) / (1 - (1 + r)^(-n)), where P is the monthly payment, r is the monthly interest rate, PV is the loan amount, and n is the total number of months. Plugging in the values, we get: P = (0.06/12 * $81,400) / (1 - (1 + 0.06/12)^(-360)). The monthly payment is $485.59. The APR can be calculated using the formula: APR = 12 * (1 - (1 - r)^12), where r is the monthly interest rate. Plugging in the value, we get: APR = 12 * (1 - (1 + 0.06/12)^12) = 6.17%. The APR for the borrower is 6.17%.
If John pays off the loan after five years, he will only pay interest for those five years. The remaining balance after five years can be calculated using the formula: B = PV * (1 + r)^n - P * ((1 + r)^n - 1) / r, where B is the remaining balance, PV is the loan amount, r is the monthly interest rate, n is the total number of months, and P is the monthly payment. Plugging in the values, we get: B = $81,400 * (1 + 0.06/12)^5 - $485.59 * ((1 + 0.06/12)^5 - 1) / (0.06/12) = $81,400 * (1 + 0.06/12)^5 - $441.11 = $78,719.82. The effective interest rate can be calculated using the formula: I = (B - PV) / (n * PV), where I is the effective interest rate. Plugging in the values, we get: I = ($78,719.82 - $81,400) / (5 * $81,400) = -0.0655. The effective interest rate is -6.55%.
If the lender imposes a prepayment penalty of 2% of the outstanding balance, and John pays off the loan after five years, the penalty amount would be 2% * $78,719.82 = $1,574.40. Therefore, the total amount John would need to pay off the loan would be $78,719.82 + $1,574.40 = $80,294.22.
