What is a Variable Rate Mortgage?
A variable rate mortgage is a home loan with an interest rate that fluctuates based on the lender’s prime rate or a benchmark rate like the Bank of Canada’s overnight rate.
Why Do Variable Rate Mortgages Matter in Real Estate
In Canada, variable rate mortgages typically offer lower initial interest rates than fixed-rate options, but the rate can change over the life of the mortgage, affecting monthly payments.
Two common types:
- Adjustable-rate: Monthly payment changes as the rate changes
- Fixed-payment variable: Payment stays the same, but interest/principal ratio shifts
Pros:
- Lower initial interest rate
- Potential savings if rates stay low
Cons:
- Risk of rising interest rates
- Harder to budget long-term
Buyers choosing a variable rate mortgage must be comfortable with uncertainty and have financial flexibility to absorb rate increases.
Understanding variable mortgages is key to selecting the right product based on risk tolerance, economic outlook, and long-term financial goals.
Example of a Variable Rate Mortgage in Action
A homeowner chooses a variable rate mortgage starting at 4.25%. When the Bank of Canada raises rates, their interest rate increases to 5.00%, and their payments rise accordingly.
