Q

Which of the following statements regarding constant payment mortgages is TRUE?

  1. There are only three basic financial components in all constant payment mortgages: amortization period, nominal rate of interest, and the loan amount.
  2. Constant payment mortgages are repaid by equal and consecutive instalments that include principal and interest.
  3. If a mortgage payment frequency and interest rate compounding frequency are both monthly, an interest rate conversion is required for mortgage finance calculations.
  4. At the end of the amortization period, a constant payment mortgage’s future value is always equal to 10% of the loan’s face value.
A

Correct Answer: 2

Option (2) is correct because constant payment mortgages are repaid by equal periodic payments that occur in consecutive instalments including the principal amount and interest. Option (1) is incorrect because there are four basic financial components in all constant payment mortgages: loan amount, nominal rate of interest, amortization period, and payment. Option (3) is incorrect because when the mortgage payment frequency and interest rate compounding frequency are the same (monthly in this case), an interest rate conversion is NOT required for mortgage finance calculations. Option (4) is incorrect because at the end of the amortization period, a constant payment mortgage’s future value is equal to zero. This is because constant payment mortgages are always completely paid off at the end of the amortization period.

Q

A borrower is considering mortgage loans from two different lenders. Lender A will loan funds at a rate of j2 = 8.5% and Lender B will loan funds at a rate of j12 = 8.6%. Which of the following represents the lowest cost of borrowing?

  1. j1 = 8.784900% with Lender B
  2. j1 = 8.839091% with Lender A
  3. j1 = 8.680625% with Lender A
  4. j1 = 8.947213% with Lender B
A

Correct Answer: 3

Option (3) is correct because Option (3) with Lender A has the lowest effective annual interest rate: (j1 = 8.680625%) and represents the lowest cost of borrowing. To compare rates, it is necessary to convert each rate into its equivalent effective annual rate and then compare from there.

Q

Which of the following statements regarding interest rates is TRUE?

  1. Equivalent interest rates are different interest rates that result in different effective annual interest rates.
  2. Financial analysts prefer using effective rates because effective rates hide the impacts of compounding within the year.
  3. If two interest rates accumulate different amounts of interest for the same loan amount over the same time period, they have the same effective annual interest rate.
  4. Two interest rates are said to be equivalent if, for the same amount borrowed, over the same period of time, the same amount is owed at the end of the period of time.
A

Correct Answer: 4

Option (4) is correct because two interest rates are said to be equivalent if, for the same amount borrowed, over the same period of time, the same amount is owed at the end of the period of time. Option (1) is incorrect because equivalent interest rates are different interest rates that result in the same effective annual interest. Option (2) is incorrect because effective rates express the true rate of interest on an annual basis since the effective rate is the annual rate with annual compounding. Option (3) is incorrect because interest rates with the same effective annual interest rate accumulate the same amount of interest for the same loan amount over the same time period.

Q

Which of the following statements regarding accelerating payments is TRUE?

  1. The accelerated biweekly payment method is typically most beneficial for mortgage loan borrowers who are paid monthly.
  2. Assuming that mortgage payments are constant, the more frequent mortgage payments are made, the longer the loan’s amortization period will become.
  3. Accelerating payments enable mortgage loan borrowers to pay off mortgage loans faster and reduce their interest costs.
  4. Accelerating payments will increase interest payments for mortgage loan borrowers.
A

Correct Answer: 3

Option (3) is correct because an accelerated payment means that mortgage loan borrowers can pay off more than the required minimum of each payment. This will decrease the interest paid over the loan term and the time needed to pay off the loan. Option (1) is incorrect because the accelerated biweekly payment method is typically most beneficial for mortgage loan borrowers who are paid biweekly, so that payments are made at the same frequency as income is received. Option (2) is incorrect because assuming that each mortgage payment is equal, the more frequent the payments are made, the shorter the loan’s amortization period becomes. This is because more of the principal is paid off faster, decreasing the time required to fully pay off the loan. Option (4) is incorrect because accelerating payments decreases the amount of time it takes to pay off the loan, which in turn decreases interest payments for mortgage loan borrowers.

Q

Alex and Kennedy are borrowing money to purchase a home and must choose between three mortgage options. The three different loans are identical except for the rate of interest charged. Assuming they prefer the lowest rate, which mortgage loan should they choose?

Loan A: 6.6% per annum, compounded quarterly
Loan B: 6.5% per annum, compounded annually
Loan C: 6.45% per annum, compounded daily

Loan A

Loan B

Loan C

They will be indifferent since the rates are all equivalent.

A

Correct Answer: 2

Option (2) is correct because Loan B has the lowest effective annual interest rate of j1 = 6.5%. To determine which loan the borrowers should choose, the effective annual rates need to be calculated for each loan.

Q

Harwinder and Suki have recently moved to Victoria because of job promotions. After renting for several months, they have bought a house just outside the city centre. Harwinder and Suki financed the purchase with a $425,000 mortgage at an interest rate of 4.99% per annum, compounded semi-annually, amortized over 25 years with a 5-year term and monthly payments.

What is the monthly payment?

  1. $2,469.40
  2. $2,790.49
  3. $2,151.49
  4. $2,520.43
A

Correct Answer: 1

Option (1) is correct because the monthly payment is $2,469.40. Payments are made monthly, so the given nominal rate with semi-annual compounding (j2 = 4.99%) must be converted to a j12 rate. Then the monthly payment can be calculated.

If we now assume that the monthly payments are rounded up to the next higher dollar, calculate the outstanding balance at the end of the 5-year term, rounded to the nearest dollar.

  1. $355,261
  2. $376,057
  3. $384,245
  4. $368,053

Correct Answer: 2

Option (2) is correct because the outstanding balance at the end of the 60-month term is $376,057, rounded to the nearest dollar. First, round the payment found in the previous question up to the next higher dollar. Re-enter this new payment and then calculate the outstanding balance after 60 monthly payments.

Q

Alex Ovichken is applying for mortgage financing in order to purchase a hockey rink. What is the maximum loan allowable (rounded to the nearest dollar), given payments of $4,000 per month, an interest rate of 5% per annum, compounded annually, and an amortization period of 20 years?

  1. $688,245
  2. $611,774
  3. $656,101
  4. $671,876
A

Correct Answer: 2

Option (2) is correct because the maximum allowable loan Alex could receive is $611,774, rounded. The interest rate must first be converted to an equivalent nominal rate with monthly compounding and the amortization period changed to months. Then solve for PV, the maximum loan allowable.

Q

Two years ago, Fraser and Glen purchased a car wash as an income-generating investment. They financed most of the purchase price with a $600,000 mortgage loan, written at an interest rate of 7.25% per annum, compounded annually. The loan has a 15-year amortization period, 5-year term, and calls for monthly payments rounded to the next higher dollar. Fraser and Glen know that interest paid on this mortgage is deductible from his income taxes. How much interest was paid during the third year of this mortgage? Round your final answer to the nearest dollar.

$39,676

$37,854

$31,495

$35,817

A

Correct Answer: 2

Option (2) is correct because interest paid during the third year is $37,854. To calculate the interest paid during the third year of this loan, the first step is to calculate the required monthly payments. Next, the total interest paid during the third year can be calculated based on the rounded payment.
