The below are the most common factors that affect what interest rate you receive for your mortgage and therefore, how much you pay.
The Type of Mortgage (Refinance, Purchase or Renewal)
Different mortgage types have varying risk profiles. For example, refinancing your mortgage generally increases your interest rate. In contrast, purchase mortgages typically have lower interest rates than refinancing because a purchase is typically an insurable transaction, which is less risky to a bank. “A refinance is not insurable at all so the bank doesn’t have the extra security of the default insurers if the borrower is to default,” notes Bernier. Your renewal interest rate varies with your creditworthiness and market conditions at the time of renewal.
Down Payment
Your mortgage interest rate decreases as the down payment fluctuates. Although counter-intuitive, the Canada Mortgage and Housing Corporation (CMHC) mandates mortgage default insurance for down payments below 20%. While you’ll receive the lowest mortgage rates with CMHC coverage, there are separate fees that can increase your cost of borrowing. Likewise, higher down payments reduce lender risk and your interest rate. Interestingly, lenders have the highest risk with a 20% down payment.
Property Type
Lenders may differentiate between freehold, leasehold and cooperative properties. The ownership structure of each option varies, adjusting lender risk. For example, some lenders charge higher interest rates for cooperative housing because the loan is not secured by a hard asset. Instead, you own shares in a housing corporation that owns the building.
Amortization Period
Extended amortization periods, which are above 25 years, generally have higher interest rates compared to shorter ones. “If you have a 10-year amortization, you are not getting a better rate than a 25-year amortization,” notes Berier. “But if you have a 26- to 30-year amortization, it may be higher than 25 or less.”
Even if your interest rate doesn’t increase, you’ll end up paying more lifetime interest with a longer amortization period. In contrast, decreasing your amortization will reduce lifetime interest paid, but will increase your monthly mortgage payment.
Mortgage Default Insurance
If your down payment is less than 20% of the property’s purchase price, you’ll be required to obtain mortgage default insurance. This insurance protects the lender in case of default. As such, lenders will charge a lower interest rate if you have default insurance. However, there are separate fees that affect your total cost of borrowing.
Payment Frequency
You can reduce the lifetime interest paid by increasing your payment frequency. This is because you will pay down your mortgage faster. However, closed mortgages have penalties for exceeding annual prepayment thresholds.
Property Location
Provinces have varying market conditions and economic factors that can impact interest rates. For example, provinces with more lender competition and robust consumer profiles will likely see decreased interest rates.
Other Mortgage Costs
In addition to the interest rate, other costs are associated with obtaining a mortgage, such as origination, appraisal and legal fees. These costs can vary among lenders and impact your mortgage’s overall affordability. Your total cost of borrowing is reflected in the mortgage APR.
