BC Broker Exam Guide: Mortgage Types Comparison

Last updated: April 2026

For candidates preparing for the British Columbia Real Estate Broker Licensing Exam, a deep understanding of real estate finance is non-negotiable. Overseen by the BC Financial Services Authority (BCFSA) and the UBC Sauder Real Estate Division, the curriculum demands that future brokers not only understand how to calculate mortgage payments but also how to advise clients on the structural differences between various mortgage products. This article provides an in-depth comparison of the primary mortgage types you will encounter on the exam and in standard BC real estate practice.

To see how this topic fits into your broader exam preparation, be sure to review our Complete BC Real Estate Broker Licensing Exam Exam Guide.

Conventional vs. High-Ratio Mortgages

The most fundamental classification of mortgages in Canada is based on the borrower's down payment and the resulting Loan-to-Value (LTV) ratio. The Office of the Superintendent of Financial Institutions (OSFI) and the Bank Act strictly regulate these categories.

Conventional Mortgages

A conventional mortgage is a loan where the down payment is equal to or greater than 20% of the property's purchase price or appraised value (whichever is lower). Because the LTV ratio is 80% or less, the lender's risk is lower. Consequently, conventional mortgages do not require default insurance, saving the borrower thousands of dollars in premium costs.

High-Ratio Mortgages

If a buyer puts down less than 20% (meaning the LTV is greater than 80%), the loan is classified as a high-ratio mortgage. Under federal law, high-ratio mortgages must be insured against default by a recognized provider, such as the Canada Mortgage and Housing Corporation (CMHC), Sagen, or Canada Guaranty.

Exam Tip: Remember that the maximum amortization period for a high-ratio, default-insured mortgage in Canada is currently capped at 25 years. You can practice the math behind these thresholds in our guide to loan-to-value and down payment calculations.

Fixed vs. Variable Rate Mortgages

Understanding how interest is calculated and applied is a heavy focus on the BC Broker exam. The choice between fixed and variable rates dictates how market fluctuations affect a borrower's obligations.

Fixed-Rate Mortgages

In a fixed-rate mortgage, the interest rate and the regular payment amount are locked in for the duration of the mortgage term (typically 1 to 5 years). Under the Canadian Interest Act, fixed-rate mortgages are generally calculated with interest compounded semi-annually, not in advance.

Prepayment Penalty: Breaking a closed fixed-rate mortgage usually incurs a penalty equal to the greater of three months' interest or the Interest Rate Differential (IRD). The IRD calculates the difference between the borrower's locked-in rate and the current market rate for the remainder of the term, which can be highly punitive in a declining rate environment.

Variable-Rate Mortgages (VRM)

Variable-rate mortgages fluctuate with the lender’s Prime Rate, which is heavily influenced by the Bank of Canada's overnight lending rate. Unlike fixed rates, variable rates are typically compounded monthly.

  • Adjustable Rate Mortgage (ARM): The payment amount fluctuates as the Prime Rate changes.
  • Variable Rate with Fixed Payments: The monthly payment remains the same, but the proportion of the payment going toward principal versus interest changes when the Prime Rate shifts. If rates rise significantly, the borrower may hit a "trigger rate," where the payment no longer covers the interest owed.

Prepayment Penalty: Breaking a variable-rate mortgage typically only costs three months' interest, making it a more flexible option for borrowers who may need to sell before the term ends.

Open vs. Closed Mortgages

The distinction between open and closed mortgages relates entirely to the borrower's prepayment privileges.

Closed Mortgages

Closed mortgages offer lower interest rates in exchange for restricted prepayment options. Most closed mortgages allow for some prepayment privileges (e.g., paying an additional 15% to 20% of the original principal per year without penalty). Paying off the entire mortgage before the term ends will trigger the IRD or three-months' interest penalty discussed above.

Open Mortgages

Open mortgages allow the borrower to pay off the mortgage in part or in full at any time without penalty. Because the lender takes on the risk of early repayment, open mortgages carry significantly higher interest rates. These are ideal for borrowers expecting a large influx of cash (like an inheritance or the sale of another property) in the near future.

Market Distribution of Mortgage Types

To give you a visual understanding of typical borrower behavior in the Canadian market, the following chart illustrates sample market share distributions among various mortgage types.

Construction Mortgages and the Builders Lien Act

Construction mortgages are advanced in "draws" as building milestones are completed. In BC, these mortgages are heavily impacted by the Builders Lien Act. Lenders will typically hold back 10% of each draw for 55 days after the issuance of a certificate of completion to protect against potential mechanics' liens from unpaid tradespeople.

Reverse Mortgages

Available to BC homeowners aged 55 and older, reverse mortgages (such as the CHIP Reverse Mortgage) allow owners to borrow up to 55% of their home’s appraised value. No regular mortgage payments are required; instead, the interest accumulates, and the loan is repaid when the homeowner moves, sells, or passes away.

Practical Exam Scenario: Advising a BC Client

Scenario: Your clients, the Chens, are purchasing a detached home in Burnaby for $1,200,000. They have $150,000 for a down payment. They plan to do substantial renovations and sell the property in two years.

Broker Analysis:

  1. LTV Calculation: Their down payment is 12.5% ($150,000 / $1,200,000). Because it is under 20%, this is a high-ratio mortgage and will require default insurance.
  2. Mortgage Selection: Because they intend to sell in two years, a 5-year closed fixed mortgage is a poor choice due to the high IRD penalty they would incur upon selling. You should advise them to consider a variable-rate mortgage (capped at a 3-month interest penalty) or a 1-to-2 year short-term fixed mortgage.
  3. Closing Costs: In addition to the mortgage, you must remind the Chens about property transfer taxes and municipal tax adjustments. You can brush up on these adjustments using our guides on property tax calculation methods and proration calculations.

Frequently Asked Questions (BC Broker Exam Focus)

1. What is the standard compounding period for a fixed-rate mortgage in Canada?

Under the federal Interest Act, fixed-rate mortgages in Canada are typically calculated with interest compounded semi-annually, not in advance. This is a crucial rule for all mortgage math questions on the UBC Sauder exam.

2. How is the prepayment penalty calculated on a closed, fixed-rate mortgage?

Lenders typically charge the greater of two amounts: three months' interest, or the Interest Rate Differential (IRD). The IRD is based on the difference between your contract rate and the current market rate for a mortgage term that matches the time remaining on your loan.

3. Can a high-ratio mortgage have an amortization period of 30 years?

No. Under current federal regulations (OSFI and the Department of Finance), high-ratio mortgages (those requiring default insurance because the down payment is less than 20%) are restricted to a maximum amortization period of 25 years.

4. What is a "trigger rate" in a variable-rate mortgage?

For a variable-rate mortgage with fixed monthly payments, the trigger rate is the point at which the interest rate rises so high that the borrower's monthly payment is no longer sufficient to cover the interest portion of the loan. At this point, the lender will require the borrower to increase their payment, make a lump-sum principal payment, or switch to a fixed rate.

5. How does the BC Builders Lien Act affect construction mortgage advances?

Under the BC Builders Lien Act, lenders advancing funds on a construction mortgage must hold back 10% of the value of the work completed for each draw. This holdback is retained for 55 days following the certificate of completion to ensure that unpaid contractors or suppliers do not register a lien against the property in priority to the lender.
