What is a Credit Score's Impact on Mortgage?
Credit score impact on mortgage refers to how a borrower’s credit score influences their mortgage eligibility, interest rate, and loan terms.
Why a Credit Score's Impact on Mortgage Matters in Real Estate
In Canadian real estate, your credit score is a major factor in determining whether you qualify for a mortgage and at what interest rate. Lenders use credit scores to assess the risk of lending money to a borrower.
Typical credit score thresholds:
- 680+: Excellent – Access to best rates and terms
- 600–679: Good – Qualifies for most mortgages
- 500–599: Fair – May need alternative lenders
- Below 500: Poor – Limited mortgage options
A higher credit score can secure better mortgage rates, which significantly reduces long-term interest costs. Conversely, a lower score may result in higher interest rates, larger down payments, or denial of mortgage approval.
Credit scores are influenced by factors such as payment history, debt levels, credit utilization, and length of credit history. Buyers can improve their score by paying bills on time, reducing debt, and avoiding unnecessary credit inquiries.
Understanding how credit score affects your mortgage options helps borrowers make strategic financial decisions and access better housing opportunities.
