What is Interest Rate?
An interest rate is the percentage charged by a lender on the amount borrowed for a mortgage, expressed as an annual rate.
Why Interest Rate Matters in Real Estate
Interest rates directly affect the cost of borrowing and the affordability of homeownership in Canada. A lower interest rate reduces monthly payments and total interest paid over the life of a mortgage, while a higher rate increases borrowing costs.
Interest rates can be fixed (unchanging over the mortgage term) or variable (fluctuating with the lender’s prime rate). Mortgage rates are influenced by the Bank of Canada’s policy rate, inflation trends, and overall economic conditions.
Understanding interest rates helps buyers make informed decisions about mortgage products, budget accurately, and lock in favorable terms during periods of rate volatility. Rate comparisons and pre-approvals can save thousands over time.
Lenders may also offer discounted rates for clients with strong credit, high down payments, or who bundle products (e.g., banking and insurance).
Example of Interest Rate
A buyer secures a 5-year fixed mortgage at a 4.2% interest rate. Over the term, they consistently pay the same rate on the outstanding principal balance.
