What Income Do You Need to Buy a $500,000 Home in Quebec?

Under guideline B-20, a regulated lender must verify that you could still carry the mortgage at a stressed rate: the greater of your contract rate plus 2% or 5.25%.

In the examples below I use a 4.25% contract rate: the real payment is computed at 4.25%, but qualification happens at 6.25%. That stressed payment drives the income requirement.

Two ratios then frame the math: GDS (gross debt service), comparing housing costs to gross income, and TDS (total debt service), which adds every other debt. On insured files the usual limits are 39% and 44%.

In Canada the minimum down payment is 5% on the first $500,000. On a $500,000 property: $25,000 down and a base loan of $475,000.

That loan must be insured. At 5% down the premium is 4.00% of the loan, or $19,000, added to the amount borrowed: the mortgage becomes $494,000.

The provincial tax on the premium cannot be financed — it is paid at the notary. At the current 9% rate that is roughly $1,710. (The rate rises to 9.975% for premiums paid after December 31, 2026.)

Over 25 years at 4.25%, the real payment is around $2,665 per month. Qualifying at 6.25% produces a payment of about $3,234 per month.

GDS adds the stressed mortgage payment, municipal and school taxes (around $400 per month at this price point, depending on the municipality) and heating (a standard $100 per month).

Monthly total: about $3,734. Divided by the 39% limit, that points to a gross household income of roughly $114,900.

In practice, if you carry debt (car, line of credit, cards), the 44% TDS ratio usually becomes the binding constraint. A $450 monthly car payment adds about $12,300 of required income.

Since December 2024, 30-year insured amortization is available to first-time buyers and to any buyer of a newly built home. It is the most effective lever to lower the qualifying payment.

Note the trade-off: the longer amortization carries a 0.20 percentage point premium surcharge. At 5% down the premium goes from 4.00% to 4.20%, or $19,950: the total loan becomes $494,950 and the premium tax about $1,796.

Despite the higher premium, the 30-year qualifying payment at 6.25% drops to roughly $3,022 per month — $212 less than over 25 years. Required gross household income falls to around $107,000.

With $100,000 down the loan is $400,000, with no insurance premium and no premium tax.

Over 25 years the qualifying payment at 6.25% is about $2,623 per month. With taxes and heating, that means a gross household income near $94,000.

An uninsured mortgage is still stress-tested at regulated lenders: the difference comes from the absence of a premium, not from easier qualification.

The welcome tax (transfer duties) on $500,000 runs roughly $6,000 to $6,500 depending on the municipality, payable a few weeks after closing.

Add notary fees, the pre-purchase inspection, tax adjustments and moving. Lenders also require a reserve, generally 1.5% of the purchase price for closing costs — $7,500 in our example.

For a condo, condo fees enter GDS as well: half of the monthly fees (sometimes all of them, depending on lender and program) is added to the calculation.

Paying off or consolidating a high-payment debt often frees more capacity than a salary increase. As a guideline, many lenders count roughly 3% of a credit card balance as the monthly payment — though the exact method varies by lender and program.

Adding a co-borrower, choosing 30 years if you qualify, or selecting a term with a lower contract rate all move the qualifying payment meaningfully.

Finally, two lenders can reach different amounts on the same file: income, debt and heating standards are not identical everywhere.
