GDS and TDS Ratios: The Two Numbers That Determine Your Mortgage Approval

Your GDS and TDS ratios are the gatekeepers of every Canadian mortgage application — understanding them helps you strategically qualify for more. These debt service ratio Canada metrics determine how much mortgage you can afford in Canada by assessing your ability to manage monthly payments. By grasping the nuances of these mortgage qualification ratios, you can optimize your financial situation and improve your chances of securing the home loan you need.

Understanding GDS Ratio

The Gross Debt Service (GDS) ratio is a crucial metric used by lenders to evaluate your ability to cover your housing costs. It represents the percentage of your gross monthly income that goes toward housing expenses, including:

• Mortgage payments (principal and interest)
• Property taxes
• Heating costs
• 50% of condo fees (if applicable)

The general rule is that your GDS ratio should not exceed 32% of your gross monthly income. However, some lenders may allow up to 39% for well-qualified borrowers.

Understanding TDS Ratio

The Total Debt Service (TDS) ratio is a broader measure that includes all your monthly debt obligations. This encompasses:

• Housing costs (as outlined in the GDS ratio)
• Car loans
• Credit card payments
• Student loans
• Personal loans

Lenders typically prefer a TDS ratio of 40% or less, but some may accept up to 44% for well-qualified borrowers.

How Are GDS and TDS Calculated?

Calculating your GDS and TDS ratios involves a straightforward formula:

For example, if your total monthly housing costs are $2,000 and your gross monthly income is $6,000, your GDS ratio would be:

1. $2,000 / $6,000 x 100 = 33.33%

Why Do GDS and TDS Matter?

Lenders use these ratios to assess your financial health and ensure you can comfortably manage your mortgage payments along with other debts. High GDS and TDS ratios indicate a greater risk of default, which is why lenders impose limits on these metrics.

Strategies to Improve Your Ratios

If your GDS or TDS ratios are too high, consider the following strategies:

• Pay down existing debts to reduce your monthly obligations.
• Increase your income through a side job or negotiating a raise.
• Consider a longer amortization period to lower your mortgage payments (note that this will increase the total interest paid over the life of the loan).

GDS and TDS Ratios for Self-Employed Individuals

Self-employed individuals often face additional challenges when it comes to GDS and TDS ratios. Lenders may require more documentation, such as:

• Notice of Assessment from the Canada Revenue Agency (CRA)
• T1 Generals for the past 2-3 years
• Business financial statements

To improve your chances of approval, ensure your financial records are up-to-date and accurate. Consider working with a mortgage broker who specializes in self-employed clients.

GDS and TDS Ratios for High-Net-Worth Individuals

High-net-worth individuals may have unique financial situations that require specialized mortgage solutions. Some lenders offer programs tailored to high-net-worth clients, which may include:

• Flexible GDS and TDS ratios
• Customized underwriting
• Exclusive interest rates

If you fall into this category, consult with a mortgage broker who understands the nuances of high-net-worth mortgages.

Bottom Line: Key Takeaways

Understanding your GDS and TDS ratios is essential for navigating the Canadian mortgage landscape. Here are some key takeaways to help you strategically qualify for more:

1. Keep your GDS ratio below 32% and your TDS ratio below 40% to improve your chances of approval.
2. Pay down existing debts, increase your income, or consider a longer amortization period to lower your ratios.
3. Self-employed individuals should ensure their financial records are up-to-date and accurate.
