6. What would be the principal amount of the loan after 30years of payments have been made?
7. What participant(s) in the setup above holds the interest rate risk associated with mortgage loans? Explain your answer.

1. Inputs in the financial calculator , to solve this question----monthly payment on the mortgage-- |
N=360; I/Y=0.5%;PV=100000,FV=0 & Enter at PMT returns the value----- 599.55 |
2. Monthly PITI for each loan |
ie. Principal,Interest, Taxes ,Insurance for each loan |
599.55+((2400+900)/12)= |
874.55 |
3. Front-end ratio= Monthly mortgage payment(PITI)/Monthly gross income |
874.55/(45000/12)= |
23.32% |
We can calculate annually also. |
Annual PITI=(599.55*12)+2400+900=10494.6 |
Annual gross income =45000 |
Front-end ratio=10494.60/45000= |
23.32% |
4. Inputs in the financial calculator , to solve this question----principal amount of the loan after 10 years of payments have been made |
N=360-120=240 ; I/Y=0.5%,PMT=599.55 FV=0 returns PV= 83685.61 |
5.Inputs in the financial calculator , to solve this question----principal amount of the loan after 20 years of payments have been made |
N=360-240=120 ; I/Y=0.5%,PMT=599.55 FV=0 returns PV= 54003.83 |
6.Inputs in the financial calculator , to solve this question----principal amount of the loan after 30 years of payments have been made |
N=360-360=0 ; I/Y=0.5%,PMT=599.55 FV=0 returns PV= 0 |
7.Participant in the above setup above holds the interest rate risk associated with mortgage loans-- |
Mortgage borrowers----if the interest rate falls , they will be paying at the old higer rates --which will be a loss to them. |
Titan investments-- who has purchased the mortgage pass thorugh, ie mortgage-backed secutities---as now , if the mortgage borrowers willl opt to prepay to re-finance at lower interest rates, and the former will be able to reap low returns only. |
8.Participant in the above setup above holds the default rate risk associated with mortgage loans-- |
NONE--- as these mortgages are GNMA approved ---GNMA & FHA are federal government agencies---who step in , in the event of default by mortgage borrowers.GNMA mortgage pass-throughs are totally free of default risks. |
9.Participant in the above setup above holds the prepayment rate risk associated with mortgage loans? |
Titan investments-- who has purchased the mortgage pass thorugh, ie mortgage-backed secutities---as now , if the mortgage borrowers , prepay to re-finance , the former will be able to reap low returns only. |
Prepayment risk & interest rate risks trigger one another. |
