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.

Buying vs. Renting in Canada: Which Makes Financial Sense for You?

By Kelly Hudson • April 3, 2025
Are you debating whether it's smarter to rent or buy a home in Canada? It's a common question, and the answer depends on your personal situation. Both renting and buying have their pros and cons, but for most people, homeownership tends to offer substantial long-term benefits. Let’s explore both options clearly, so you can confidently decide what’s best for you. Advantages of Buying a Home 1. Personal Freedom and Customization Owning your home means having the freedom to personalize your living space. Dreaming of a bold paint colour or unique flooring? Go ahead—your home, your rules! 2. Building Equity and Wealth Each mortgage payment you make is an investment in yourself. Over time, your home typically appreciates in value, increasing your equity. This can become a significant asset that helps secure your financial future. 3. Stability and Security Owning offers peace of mind. You don’t need to worry about sudden rent hikes or eviction notices. Your home remains yours until you decide otherwise. 4. Long-Term Financial Benefits Homeownership acts as forced savings. Unlike renting, every mortgage payment moves you closer to outright ownership, building a financial foundation that can support you and your family for years to come. Challenges of Buying a Home 1. Upfront Costs Buying comes with significant initial costs, including a down payment, legal fees, home inspection, appraisal, moving expenses, etc. 2. Responsibility for Maintenance Owning a home means you're responsible for maintenance and repairs. This can sometimes be costly and inconvenient. 3. Reduced Flexibility Selling a home typically takes time, which can limit your flexibility if you need or want to relocate quickly. Advantages of Renting 1. Easy Mobility Renting offers flexibility to relocate easily, beneficial for frequent job changes or lifestyle adjustments. 2. Fewer Responsibilities Repairs and maintenance are generally your landlord’s responsibility, reducing stress and unexpected expenses. 3. Lower Initial Costs Renting typically requires just a security deposit and the first month's rent, making it easier financially at the start. Downsides of Renting  1. No Equity Building Rent payments do not contribute to your equity. Instead, you’re effectively paying your landlord’s mortgage, offering no long-term financial return. 2. Restrictions and Rules Landlords often impose limitations, such as no pets or restrictions on decorating, making it challenging to feel fully at home. 3. Instability and Uncertainty Renters may face sudden rent increases or eviction if the landlord decides to sell or repurpose the property, disrupting your life significantly.
