Understanding Debt and Its Impact on Mortgage Approval

Kelly Hudson • March 13, 2024

Securing a mortgage significantly depends on your credit score and debt load. Understanding how different types of debt affect mortgage affordability is crucial.


Debt falls into two categories: secured and unsecured. 

  • Secured debt, backed by collateral like a house or car, provides lenders security in case of default. 
  • Unsecured debt, such as credit cards, lines of credit, and student loans, poses higher risk for lenders and typically carries higher interest rates.


Here's how different types of debt influence your credit score and mortgage approval:

  1. Credit Cards are unsecured debt, offering revolving credit lines with interest rates based on creditworthiness. Responsible credit card usage can positively affect credit scores, but defaults or late payments can lead to higher interest rates and decreased creditworthiness.
  2. Line of Credit: Like credit cards, lines of credit are unsecured and provide borrowers access to a predetermined credit limit. Responsible use can improve credit scores, while defaults can have negative credit repercussions.
  3. Student Loans: Despite being unsecured, they can enhance credit scores if paid on time. They contribute to the debt-to-income ratio.
  4. Auto Loans: Auto loans are secured debt, with the vehicle serving as collateral. They can diversify debt portfolios and improve credit scores. 
  5. Existing Mortgage Loans: Secured by the property, timely payments enhance credit scores. Missed mortgage payments raise red flags for new lenders.


Maintaining a balanced mix of debt types strengthens credit scores and mortgage eligibility. However, over-borrowing can be harmful.

Mortgage lenders aim for a debt-to-income ratio below 43%, considering all your debts. Ensuring income covers all payments is crucial for approval.


Understanding debt intricacies is vital for navigating the mortgage application process. Ideally, less debt means a bigger mortgage, since more of your income can go to cover your mortgage payments.

  • For instance, a $500/month auto loan decreases your mortgage affordability by about $100K.


Practicing responsible borrowing and effective debt management increases chances of securing the needed mortgage for homeownership goals.

By Kelly Hudson • March 6, 2026
Decisions relating to real estate can have significant financial and legal consequences. Before deciding how to share ownership of what is likely one of the largest investments of your life, I recommend consulting a real estate lawyer. Many Canadians purchase property together — including spouses, common-law partners, family members, friends, and business partners. Because ownership structure affects estate planning, taxes, creditor exposure, and control over the property, it’s important to understand your options before you sign.
