How Much Mortgage Can You Afford in Quebec?

Buying a home is one of the biggest financial decisions you will make. Before you start looking at properties, it is important to understand how much mortgage you can realistically afford.
Your mortgage affordability depends on several factors, including your income, existing debts, down payment, credit history, interest rate, property taxes, and other housing costs.
In Quebec, lenders also use specific debt-service ratios and a mortgage stress test to determine how much you may qualify to borrow. However, the amount a lender approves is not always the same as the amount you should comfortably spend.

What Determines How Much Mortgage You Can Afford?

Lenders generally look at several important factors when reviewing your mortgage application.

These include:

• Your gross household income
• Your monthly debt payments
• Your down payment
• Your credit history
• Your mortgage interest rate
• Your amortization period
• Property taxes
• Heating costs
• Condo fees, if applicable
• The purchase price and type of property

All of these factors work together to determine your borrowing capacity.

1. Your Income

Your income is one of the most important factors in determining mortgage affordability.

Lenders generally look at your gross income before taxes. If you are purchasing a home with a spouse or co-borrower, eligible income may be combined when assessing your application.

Income can come from sources such as:

• Employment income
• Self-employment income
• Business income
• Commission income
• Bonus income
• Rental income
• Other eligible sources

For self-employed individuals and business owners, additional documentation may be required to
verify income.

2. Your Existing Debts

Your current debts can significantly affect how much mortgage you can qualify for.

Lenders may consider payments related to:

• Car loans
• Credit cards
• Lines of credit
• Student loans
• Personal loans
• Other mortgages
• Support payments

For example, two people with the same income may qualify for different mortgage amounts if
one person has significantly higher monthly debt payments.

Reducing existing debt before applying for a mortgage may improve your borrowing capacity.

3. Understanding GDS and TDS Ratios

Canadian lenders use debt-service ratios to evaluate whether your income is sufficient to support
your housing costs and overall debt obligations.

The two important ratios are GDS and TDS.

Gross Debt Service Ratio

GDS measures your housing-related expenses compared with your gross household income.

Housing costs generally include:

• Mortgage principal and interest
• Property taxes
• Heating costs
• 50% of eligible condo fees

For insured mortgages, CMHC’s standard maximum GDS ratio is 39%.

Total Debt Service Ratio

TDS looks at your housing costs plus your other monthly debt obligations.

This can include:

• Mortgage payments
• Property taxes
• Heating costs
• Eligible condo fees
• Car payments
• Credit card obligations
• Personal loans
• Lines of credit
• Student loans

For insured mortgages, CMHC’s standard maximum TDS ratio is 44%.

These ratios help lenders determine the maximum amount of debt you can carry.

4. The Mortgage Stress Test

Another important factor is the mortgage stress test.

Federally regulated lenders generally require borrowers to qualify at a higher interest rate than the actual mortgage rate. The qualifying rate is the higher of:
• 5.25%
• Your contractual mortgage rate plus 2%

This means that even if your actual mortgage rate is lower, the lender may calculate your affordability using a higher qualifying rate.

The stress test is designed to determine whether you could continue making your mortgage payments if interest rates were to increase.

5. Your Down Payment

Your down payment also affects how much you can afford.

A larger down payment means you need to borrow less money, which can reduce your mortgage payment and overall interest costs.

Your down payment may come from:

• Personal savings
• FHSA funds
• RRSP withdrawals through the Home Buyers’ Plan
• A financial gift from an eligible family member
• Other acceptable sources

Remember that your down payment is not the only money you need when purchasing a property.

6. Don’t Forget Closing Costs

Many buyers focus on the down payment and forget about the other costs associated with purchasing a home.

Depending on your transaction, you may need to budget for:

• Notary or legal fees
• Welcome tax in Quebec
• Home inspection
• Property appraisal
• Title insurance
• Tax adjustments
• Moving expenses
• Mortgage insurance-related costs, where applicable

Your actual closing costs will depend on the property and transaction. Government guidance commonly recommends budgeting additional funds beyond the down payment for these expenses.

7. Property Taxes and Heating Costs

Your mortgage payment isn’t your only monthly housing expense.

When calculating affordability, you should also consider:

• Municipal property taxes
• School taxes
• Heating and electricity
• Home insurance
• Condo fees
• Maintenance
• Repairs

Some of these expenses are considered in lender qualification calculations, while others are important for your personal budget.

This is why you should always create your own monthly budget instead of relying only on the maximum amount a lender says you qualify for.

8. Your Credit Profile Matters

Your credit history can influence your mortgage options and the interest rate available to you.

Before applying, consider:

• Paying bills on time
• Reducing credit card balances
• Avoiding unnecessary new credit applications
• Checking your credit report for errors
• Paying down high-interest debt

A stronger credit profile can help you access more mortgage options.

9. Fixed vs. Variable Mortgage Rates

The type of mortgage rate you choose can also affect your monthly payment and affordability.

A fixed-rate mortgage generally provides predictable payments during the mortgage term.

A variable-rate mortgage can change as the underlying interest rate changes, depending on the mortgage product.

When choosing between the two, consider:

• Your budget
• Your tolerance for payment changes
• Your financial goals
• Current and expected interest-rate conditions
• The mortgage’s terms and features

The lowest advertised rate is not always the best mortgage for your situation.

10. Your Amortization Period

The amortization period is the total length of time it takes to repay your mortgage.

A longer amortization can reduce your required monthly payment and may increase the amount you qualify for, but it can also result in more interest paid over the life of the mortgage.

Your available amortization options depend on factors such as:

• Your down payment
• Whether mortgage insurance is required
• Your property type
• Your lender
• Your borrower profile

Discuss the long-term cost before choosing an amortization period.

How Much Mortgage Can You Afford?

There is no single mortgage amount that applies to everyone.

For example, someone earning $100,000 per year with very little debt may have significantly more borrowing capacity than someone with the same income but substantial monthly loan payments.

Your affordability is based on the combination of:

• Income
• Debt
• Down payment
• Housing costs
• Interest rate
• Stress-test qualification
• Credit profile
• Lender guidelines

CMHC provides affordability and debt-service calculators that can help consumers estimate their borrowing capacity.

Maximum Mortgage vs. Comfortable Mortgage

One of the biggest mistakes buyers make is assuming that the maximum amount a lender approves is the amount they should spend.

These are not necessarily the same.

Your personal budget should also allow room for:

• Emergency savings
• Retirement contributions
• Home repairs
• Unexpected expenses
• Vacations and lifestyle costs
• Future changes in income
• Rising household expenses

A mortgage that fits your lifestyle is often more valuable than simply purchasing the most expensive home you qualify for.

How to Increase Your Mortgage Affordability?

If your current borrowing capacity isn’t enough for the property you want, there are several ways you may be able to improve your position.

Consider:

1. Increasing your down payment.
2. Paying down existing debts.
3. Improving your credit profile.
4. Increasing your documented income.
5. Considering a longer amortization if appropriate.
6. Comparing different mortgage lenders.
7. Purchasing a property with lower taxes or condo fees.
8. Applying with an eligible co-borrower.

The right strategy depends on your financial circumstances.

Example of Mortgage Affordability

Consider a household with:

• $100,000 gross annual income
• $8,333 gross monthly income
• $500 in monthly debt payments
• A $50,000 down payment
• Property taxes and heating costs
• A mortgage application subject to the applicable stress test

The lender would assess the household’s income, housing costs and existing debts using the applicable GDS and TDS calculations.

The final mortgage amount would depend on the interest rate, amortization period, property expenses, down payment and lender’s guidelines.

This is why online calculators can provide a useful starting point, but they should not be treated as a guaranteed mortgage approval.

Quebec-Specific Costs to Consider

Buying a property in Quebec involves expenses that should be included in your overall budget.

One important cost is the Quebec Welcome Tax, also known as the land transfer tax or droits de mutation immobilière.

You may also need to budget for:

• Notary fees
• Property inspection
• Appraisal
• Title insurance
• Tax adjustments
• Moving expenses
• Property insurance
• Renovation or maintenance costs

The exact amount varies depending on the property, municipality and transaction.

Should You Get Mortgage Pre-Approved?

A mortgage pre-approval can help you understand your potential borrowing range before you begin making offers.

It can help you:

• Establish a realistic home-buying budget
• Understand your potential monthly payment
• Identify documentation requirements
• Compare mortgage options
• Demonstrate to sellers that you are financially prepared

However, a pre-approval is not the same as final mortgage approval. The lender may still need to review the property and complete additional underwriting before closing.

How a Mortgage Broker Can Help?

Calculating mortgage affordability can become complicated when you have multiple income sources, business income, existing debt or other financial considerations.

A mortgage broker can help you:

• Review your financial situation
• Calculate your potential borrowing capacity
• Compare multiple lenders
• Explain mortgage options
• Identify potential qualification issues
• Help prepare your documentation
• Find financing that fits your circumstances

Different lenders may have different lending guidelines, so comparing options can be valuable.
