Buying your first home is exciting. It’s a big life step. But before you start touring properties and imagining your future space, there’s one important factor that can shape your approval outcome — your debt.
If you’re applying for a first-time home buyer mortgage, lenders will carefully examine your existing financial obligations. Debt does not automatically disqualify you. However, it directly affects:
Let’s break this down in a simple, easy-to-understand way.
Why Debt Matters in Mortgage Approval
When lenders review your application, they’re asking one main question:
Can you comfortably afford this mortgage payment?
To answer that, they look at:
Debt tells lenders how much of your income is already committed. If too much is going toward other loans, there may not be enough room left for a mortgage.
It’s not about whether you have debt. Most first-time home buyers do. It’s about whether your debt is manageable compared to your income.
Lenders use two calculations to measure affordability. These numbers are critical for any first-time home buyer mortgage approval.
This ratio measures how much of your income would go toward housing costs only.
Housing costs include:
Most lenders prefer this number to stay below 39%.
This is where your other debts come into play.
TDS includes:
Most lenders want this ratio below 44%.
If your TDS is too high, your approval amount decreases — or your application may be declined.
Not all debt carries the same weight. Here’s how lenders typically view common debts.
Credit card balances can impact your approval more than you think.
Lenders usually calculate a minimum payment of about 3% of your outstanding balance. So if you owe $10,000, they may count $300 per month toward your debt — even if you pay less.
Because credit cards have high interest rates, they can significantly affect your total debt ratio.
Car loans are straightforward. Lenders simply include your monthly car payment in your TDS calculation.
A $600 monthly car payment reduces your mortgage affordability by a noticeable amount.
Student loans are included based on the required monthly payment. They do not automatically hurt your chances — especially if your income comfortably supports the payment.
These are also counted in your monthly obligations. Even if you don’t use the full limit, the required payment affects your debt ratio.
Let’s say you earn $90,000 per year.
If you have:
That’s $1,000 per month in debt.
That $1,000 directly reduces how much you qualify for. In many cases, it can lower your mortgage approval amount by tens of thousands of dollars.
This is why working with experienced mortgage specialists before applying can make a significant difference.
Yes.
Most people buying their first home carry some debt. Approval depends on:
Debt becomes a problem only when it pushes your TDS ratio beyond lender limits.
If you plan to apply for a first-time home buyer mortgage in the next 6–12 months, here are smart steps to consider.
Paying down credit card balances improves:
Even reducing balances below 50% of your limit can help.
Financing furniture, buying a new car, or opening new credit accounts before closing can hurt your approval.
Many buyers don’t realize that new loans can change their ratios immediately.
On-time payments build lender confidence. Even one missed payment can affect your credit score.
This is where experienced mortgage brokers in Mississauga can help. Instead of guessing, you can review your numbers and see exactly how your debt impacts approval.
If your ratios exceed standard guidelines, that doesn’t mean you’re out of options.
Professionals offering comprehensive mortgage agency services have access to:
Sometimes restructuring debt or consolidating loans can improve your position before applying.
Not necessarily.
Lenders look at:
If improvement is needed, a knowledgeable mortgage advisor can outline steps to strengthen your application before submission.
Not always.
Paying off smaller debts may improve ratios, but using all your savings to clear loans could reduce your down payment or emergency funds.
A balanced approach works best. Reviewing different scenarios with qualified mortgage specialists helps you make smart decisions.
How Debt Affects the Mortgage Stress Test
In Canada, most borrowers must pass a stress test. Lenders evaluate whether you can afford payments at a higher interest rate than your contract rate.
Higher debt makes passing this test more difficult. Lower debt improves flexibility and approval strength.
If you’re serious about buying, start planning well in advance. Preparing early allows you to:
Many successful first-time home buyers don’t rush. They prepare.
Debt does not automatically stop you from buying a home. It simply affects:

Yes. Many buyers carry credit card balances. Approval depends on how the balance compares to your income and whether payments are consistent.
It depends on your financial situation. Paying it off can improve your debt ratio, but you should not drain your savings without reviewing the impact first.
Student loans are included in your debt ratio, but they rarely prevent approval if your income supports the payment comfortably.
There isn’t a fixed dollar amount. Lenders focus on your Total Debt Service ratio. If your total monthly obligations exceed roughly 44% of your gross income, approval becomes more difficult.
Ideally six to twelve months before you plan to buy. Early planning allows time to reduce debt, improve credit, and increase your approval potential.
