# Comprehensive Review Problem 4

Comprehensive Review Problem 4-21

A mortgage loan in the amount of \$100,000 is made at 6 percent interest for 20 years. Payments are to be monthly in each part of this problem.
Required:

a. What will monthly payments be if

(1) The loan is fully amortizing?

(2) It is partially amortizing and a balloon payment of \$50,000 is scheduled at the end of year 20?

(3) It is a nonamortizing, or “interest-only” loan?

(4) It is a negative amortizing loan and the loan balance will be \$150,000 at the end of year 20?

Par A. This part is all correct (A1= 716.43, A2=608.22, A3 500.00, A4= 391.78)

b. What will the loan balance be at the end of year 5 under parts a (1) through a (4)?

Part B: These parts I have correct B1= 84,899.60, B3= 100,000.00. These parts I need an explanation and I have wrong are B2=92,449.80, and B4= 107,550.20.

c. What would be the interest portion of the payment scheduled for payment at the end of month 61 for each case (1) through (4) above?

Part C: The parts I have correct are C1=424.50, C3= 500.00, and C4= 537.75. The part I have wrong and I need explanation is C2= 462.25

d. Assume that the lender charges 3 points to close the loans in parts a (1) through a (4). What would be the APR for each?

Part D: All is correct D1= 6.38%, D2= 6.31%, D3 = 6.26, and D4 = 6.23.

e. Assuming that 3 points are paid at closing and the 20-year loan is prepaid at the end of year 5, what will be the effective rate of interest for each loan in parts a (1) through a (4)?

Part E: I have everything wrong. I need full explanation for this one.

f. Assume the loan is fully amortizing except that payments will be “interest only” for the first three years (36 months). If the loan is to fully amortize over the remaining 17 years, what must the monthly payments be from year 4 through year 20?

Part F: Is correct 783.10

g. If this is a negative amortizing loan and the borrower and lender agree that the loan balance of \$150,000 will be payable at the end of year 20:

(0) Total Interest.

(1) How much total interest will be paid from all payments? How much total principal will be paid? This I have correct. G1 b=100,000

(2) What will be the loan balance at the end of year 3?

(3) If the loan is repaid at the end of year 3, what will be the effective rate of interest?

(4) If the lender charges 4 points to make this loan, what will the effective rate of interest be if the loan is repaid at the end of year 3?

In this part I have almost all wrong G0, G2, G3 , and G4 I need full explanation, except part G1 = 100,000

I explain in each part what I have questions about. Can you help me?. As you can see some parts I have correct.
