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.

What Is BC Assessment? Every January, British Columbia homeowners receive their annual Property Assessment Notice . BC Assessment is a provincial Crown corporation responsible for valuing all real estate in British Columbia for property tax purposes. Each year, BC Assessment provides an estimate of a property’s fair market value as of July 1 of the previous year . 👉 To view the most recent assessment for any property, visit the BC Assessment website and search by address. Important things to understand about BC Assessments Timing matters. Your 2026 assessment reflects an estimated market value as of July 1, 2025, not today. Markets change quickly. In active or volatile markets (like Greater Vancouver and the Fraser Valley), values can shift significantly in a matter of months. Mass appraisal methods are used. BC Assessment relies on algorithms and broad market data rather than a detailed, in-person inspection of your specific home. Because of this, an assessed value can differ — sometimes substantially — from: a lender-ordered mortgage appraisal, or a private real estate appraisal completed for buying or selling. BC real estate context (2026) As we move through 2026, BC housing markets continue to be influenced by: interest-rate expectations and changes by the Bank of Canada, affordability pressures, regional supply constraints, and local economic conditions. This means BC Assessment values should be used only as a starting point , not as a precise indicator of what a property will sell for or what a lender will accept as value. Bottom line: Do not rely on BC Assessment for the exact value of a property you’re planning to sell, purchase or refinance.
