How Much Condo Can I Afford in Ontario?

Condo affordability is about more than the maximum mortgage a lender may approve. Your down payment, interest rate, condo fees, property taxes, debts and everyday ownership costs all affect what a condo will actually cost each month.

Affordability has two different meanings

When people ask how much condo they can afford, they are often asking two different questions.

What can I qualify for?

This is primarily a lending question. Mortgage lenders consider your income, debts, down payment, credit profile, qualifying interest rate and other requirements.

What can I comfortably carry?

This is a personal budgeting question. It includes the mortgage but also condo fees, property taxes, insurance, utilities, parking, maintenance and the rest of your financial life.

Those numbers do not have to be the same. A mortgage approval tells you what financing may be available under a lender's criteria. It does not automatically tell you what monthly housing cost will feel comfortable in your budget.

1. Start with your down payment

Your down payment affects both how much you need to borrow and whether mortgage loan insurance will generally be required.

Canada's current minimum down-payment requirements depend on the purchase price.

Purchase priceMinimum down payment
$500,000 or less5% of the purchase price
$500,000 to less than $1.5 million5% of the first $500,000 + 10% of the amount above $500,000
$1.5 million or more20% of the purchase price

For example, the minimum down payment on a $700,000 property is $45,000: $25,000 on the first $500,000 plus $20,000 on the remaining $200,000.

2. Less than 20% down can change the mortgage

If your down payment is below 20%, you will typically require mortgage loan insurance when the mortgage and property meet the applicable eligibility requirements.

Mortgage insurance protects the lender rather than the buyer. Its premium generally depends on the size of the mortgage relative to the property's value.

The insurance premium can generally be added to the mortgage, increasing the amount being financed. Ontario also applies provincial sales tax to mortgage-insurance premiums, and that tax cannot be added to the mortgage.

That means two buyers purchasing the same condo at the same price can have different mortgage balances and upfront costs simply because their down payments differ.

3. Lenders look at debt-service ratios

Mortgage qualification is not based on income alone. Debt service ratios compare housing and debt obligations with gross household income.

GDS — Gross Debt Service

Measures qualifying housing costs relative to gross household income.

TDS — Total Debt Service

Adds other debt obligations to qualifying housing costs and compares the total with gross household income.

For CMHC-insured mortgages, the maximum thresholds are generally 39% for GDS and 44% for TDS.

Other debt payments can therefore reduce mortgage affordability even when your income stays exactly the same. Car loans, credit cards, lines of credit and other obligations can matter when a lender evaluates the application.

4. Condo fees matter twice

Condo fees matter when evaluating affordability because they are an ongoing monthly expense. They can also affect mortgage qualification.

Under CMHC's debt-service calculations, 50% of applicable condo fees are included when calculating GDS and TDS.

Example

If a condo charges $700 per month in condo fees, the actual household cash expense is $700. For the applicable CMHC debt-service calculation, 50% — or $350 — is included.

This distinction is important. A qualification formula and your real monthly budget are measuring different things.

5. The mortgage stress test can reduce your qualifying amount

Mortgage qualification generally involves testing whether the borrower could handle payments at a higher interest rate than the actual contract rate.

For federally regulated uninsured mortgages, the minimum qualifying rate is currently the greater of the mortgage contract rate plus 2 percentage points or 5.25%.

CMHC's insured-mortgage debt-service calculations similarly use the greater of the contract rate plus 2% or 5.25% for applicable insured programs.

As a result, the payment used to determine whether you qualify can be higher than the payment you would actually make at your contracted mortgage rate.

6. Your real monthly cost is bigger than the mortgage

Once you move from mortgage qualification to personal affordability, the list of costs gets longer.

A realistic condo budget may include:

  • • Mortgage payment
  • • Condo fees
  • • Property taxes
  • • Condo insurance
  • • Electricity
  • • Heating or other utilities
  • • Internet
  • • Parking
  • • Locker costs
  • • Maintenance inside the unit

Some utilities or amenities may already be included in a building's condo fees. Others may be billed separately. That is why reviewing the specific condo's expenses is more useful than assuming every building costs the same amount to operate.

7. Do not use all of your cash for the down payment

A common affordability mistake is looking only at whether you have enough money for the down payment.

Buying a condo can also require cash for land transfer tax, legal expenses, title insurance, mortgage-insurance tax where applicable, adjustments and other closing expenses.

You may also want money available after closing rather than moving into a property with no financial cushion.

8. A higher condo price is not the only thing that raises your monthly cost

Purchase price gets most of the attention, but several variables can materially change affordability.

Interest rate

A higher mortgage rate increases the payment required for the same mortgage balance.

Down payment

A larger down payment reduces the amount financed and may eliminate mortgage default insurance once it reaches the applicable threshold.

Condo fees

Two similarly priced condos can have very different monthly carrying costs when their condo fees differ.

Property tax

Property taxes add another recurring ownership cost and also matter in mortgage qualification.

9. Compare condos using total monthly ownership cost

Imagine two condos listed for similar prices.

One may have lower condo fees but higher property taxes and separately metered utilities. Another may charge higher condo fees but include some utilities or amenities.

Looking only at the listing price — or even only at the mortgage payment — can hide those differences.

Comparing the estimated total monthly ownership cost gives you a more useful way to compare properties with different fee structures.

10. Qualification is not the same as comfort

A lender's approval process answers whether a mortgage fits its underwriting requirements. Your own budget has to answer a broader question.

Consider what remains after housing costs for groceries, transportation, debt repayment, savings, emergencies, travel, entertainment and other priorities.

Choosing a purchase price below your theoretical maximum may leave more room for those expenses and for costs that increase after you buy.

Condo Cost Ontario is a planning and educational tool, not a mortgage pre-approval or affordability determination.

Mortgage qualification depends on lender and insurer requirements, income verification, debts, credit history, property characteristics and other factors that this guide cannot fully account for.
