How Your Credit Score Affects Your Mortgage Rate

Your credit score plays a meaningful role in the mortgage rate a lender may offer you, alongside factors like your income, debt load, and down payment. Understanding how lenders view credit can help you make informed decisions before you start shopping for a mortgage.

Why Lenders Care About Your Credit Score

Lenders use your credit score as one signal of how reliably you have managed debt in the past. In Canada, scores from Equifax and TransUnion typically range from 300 to 900, and most federally regulated lenders like the big banks look for scores in the mid-600s or higher to consider you for their best conventional rates. A higher score generally suggests to a lender that you have a track record of making payments on time and managing credit responsibly.

This does not mean your score is the only factor that matters. Lenders also weigh your gross debt service (GDS) and total debt service (TDS) ratios, your employment stability, and the size of your down payment. Credit score tends to work alongside these other factors rather than replacing them, but it can influence which lenders are willing to work with you and what kind of terms they may offer.

How Credit Score Ranges May Affect Rate Offers

Generally speaking, borrowers with stronger credit scores, often in the 700s and above, may have access to a wider range of lenders and potentially more competitive rate offers. This is because lenders view strong credit history as lower risk. For example, to illustrate the concept, a borrower with a score of 760 and stable income might be offered a rate close to a lender's posted best rate, while a borrower with a score closer to 620 might be offered a rate slightly higher to account for perceived risk. These numbers are illustrative only and not a reflection of current rates.

Borrowers with lower scores, roughly in the 600 to 650 range, may still qualify for a mortgage, but could be directed toward alternative or B-lenders, which sometimes come with higher rates and additional fees. Below a certain threshold, often around 600, qualifying with an A-lender becomes more difficult, and private lending options may come into play. Every lender sets its own internal thresholds, so these ranges can vary.

Other Factors That Influence Your Rate Alongside Credit

Credit score is just one piece of the puzzle. Your down payment size matters too, since a larger down payment reduces the lender's risk and may result in more favourable terms. Whether your mortgage is insured through the Canada Mortgage and Housing Corporation (CMHC) or a similar insurer also affects pricing, since insured mortgages are sometimes associated with different rate structures than uninsured ones.

The type of mortgage product you choose, fixed versus variable, and the term length, also plays into the rate you are offered. Lenders may also look at how many credit inquiries appear on your file recently, your credit utilization ratio, and how long you have held credit accounts. A thin credit file, meaning very little credit history, can sometimes be treated similarly to a lower score simply because the lender has less information to assess.

Steps to Take Before You Apply

Reviewing your credit report from both Equifax and TransUnion before applying for a mortgage can help you catch errors or outdated information that might be dragging your score down unnecessarily. Canadians are entitled to a free copy of their credit report from each bureau, though monitoring services that show your score may come with a fee.

It may also help to avoid opening new credit accounts or making large purchases on credit in the months leading up to your mortgage application, since this can affect both your score and your debt ratios. Paying down revolving credit balances, such as credit cards, ahead of applying could improve your credit utilization ratio, which is one of the factors that influences your score.

A mortgage broker can be a useful resource here, since they often have access to multiple lenders with different credit requirements and risk appetites. Depending on your credit profile, a broker may be able to identify lenders who are better suited to your specific situation, which can be harder to figure out on your own.
