Minimum down payment or 20%: what real impact does it have on your mortgage in Quebec?

Minimum down payment or 20%: what real impact does it have on your mortgage in Quebec?

Are you hesitating between putting the minimum (5–10–15%) or saving 20% of a down payment to buy a house, a condo, or a plex?

Beyond the sense of security, this choice directly influences:

• your interest rate
• your monthly payments
• your debt ratios
• your chances of obtaining financing
• your future flexibility (refinancing, investments, etc.)

Here, concretely, is what it changes for a first-time buyer or a real estate investor in Quebec.

1. Minimum down payment: the entry ticket into real estate

a) Reminders of the down payment rules

For a first-time buyer or not, the federal rules (valid in Quebec) are the same:

• 5% on the portion of the price up to $500,000
• 10% on the portion between $500,000 and $1.5M
• 20% minimum if the price is $1.5M and up (uninsured mortgage)

Typical examples:

• House or condo occupied by the owner: possible with 5% down payment.
• Duplex (two-family) occupied by the owner: possible with 5%.
• Triplex or 4-plex occupied by the owner: minimum 10%.
• 1–4 unit building fully rented (not owner-occupied): minimum 20%, no traditional high-ratio mortgage.

b) CMHC insurance: the hidden cost of small down payments

If you put less than 20%, your mortgage must be insured (CMHC / SCHL, Sagen or Canada Guaranty).

Consequences:

• Insurance premiums (as a % of the loan) are added to your mortgage.
• You pay interest on these premiums during the entire amortization.
• In Quebec, the GST/HST on the premium must be paid in cash at the notary.

The smaller the down payment (5% versus 10–15%), the higher the premium.

For a 30-year term with 5% down, there is even a premium of about 0.2%.

The advantage:

• The interest rates for insured loans are often a bit lower than for a conventional mortgage (20%+), because the bank's risk is guaranteed by the insurer.

2. Down payment of 20% and above: the "conventional" mortgage

With 20% down payment or more, your loan is usually uninsured.

Key advantages:

1. No SCHL insurance premium

• The savings can represent several thousands, or even tens of thousands of dollars over the term.
• Each payment then goes more directly toward principal rather than repaying a premium.

1. More equity from day one

• Easier to refinance later to renovate, invest in another property, or consolidate debts.
• A drop in property value affects you less because your cushion is larger.

1. Better lender perception of the file

• For some riskier profiles (recent self-employment, average credit), arriving with 20–25% can compensate for a slightly less-than-perfect file.

Points to watch:

• The conventional rates can be slightly higher than insured rates.
• The lender assumes the risk, so it may price a bit higher.

In other words, you trade:

• No insurance premium + more equity,
• against
• Rates sometimes a bit higher than the insured equivalent.

3. Impact on your debt ratios and your borrowing capacity

Lenders look at two main ratios:

• Gross debt service ratio (GDS / HDS): housing (mortgage, taxes, heating, sometimes condo) / gross income
• Total debt service ratio (TDS / TDS): housing + all other payments (auto, cards, loans, etc.) / gross income

The usual thresholds are around 39% / 44% for a standard file.

How down payment influences your indebtedness

1. More down payment = smaller mortgage

• Thus lower monthly payments → lower debt ratios.
• You can sometimes afford a slightly more expensive home or condo while staying within norms.

1. Less down payment = larger mortgage + built-in insurance premium

• Your payments are higher, so your debt ratios rise.
• You may need to adjust: property price, type of property (condo vs house), or even your other debts (pay off a car loan, for example).

1. For a plex (duplex, triplex, 4-plex)

• Rental income can help push ratios, especially if you will occupy one unit.
• But lenders often consider only a portion (e.g., 50–70% of rents) to stay prudent.

4. First-time buyer: should you absolutely target 20%?

Scenarios where the minimum down payment makes a lot of sense

• You are a first-time buyer, you already pay high rent, and waiting 5–7 years to save 20% makes you miss potential price increases.
• Your priority is to enter the real estate market quickly, even with a small down payment.
• You are eligible for assistance programs (RAP, incentives, etc.) and your debt ratios remain acceptable even with 5–10%.

In this case, accepting the SCHL premium can be a sensible cost to break the rent cycle.

Scenarios where it's better to aim for 20% (or more)

• Your debt ratios are already maxed out because of other debts.
• You anticipate more unstable incomes (self-employment, career change).
• You think you’ll want to refinance soon for a project: buy a plex, consolidate high-rate debts, etc.
• You have the ability to save quickly and build your down payment without waiting 5–10 years.

In these cases, aiming for 20% down can give you precious room to maneuver.

5. House, condo, or plex: the role of the down payment in your strategy

Single-family home

• Primary objective: stability, quality of life.
• With minimum down payment, you maximize accessibility, but you accept higher indebtedness and the insurance premium.
• With 20%+, you reduce monthly pressure and leave more room in the family budget (kids, car, travel).

Condo

• Be mindful of the condo fees that are included in the debt calculation.
• A higher down payment can offset these fees to stay within acceptable ratios.
• A good choice for a first-time buyer in the city, provided you thoroughly analyze the financial health of the condo association.

Plex (duplex, triplex, 4-plex)

• Here, the down payment becomes a real investment lever.
• The more you put down, the more comfortable your net payments after rents are.
• For a plex, a good strategy can be:
• start with a minimum down payment on a small owner-occupied duplex,
• benefit from value appreciation and capital repayment,
• then refinance later to buy another building.

6. Interest rates: insured vs uninsured

In Quebec as elsewhere in Canada:

• Insured mortgage (less than 20%)
• Usually slightly better displayed rate.
• But insurance premium added to the principal.
• Conventional mortgage (20% and up)
• Rates sometimes a bit higher,
• but no premium, hence less interest paid over the total term.

The important thing is not only the rate but the total cost of financing over, for example, 25 or 30 years.

7. Minimum down payment vs 20%: how to decide?

In short:

• Minimum down payment (5–10–15%)
• + Allows you to become a homeowner faster (house, condo, owner-occupied plex).
• + Often access to good insured rates.
• – SCHL insurance premium + GST/HST.
• – Higher indebtedness, tighter maneuverability.
• Down payment of 20% and more
• + No premium, total cost often lower in the long term.
• + More comfortable debt ratios.
• + Greater flexibility (refinancing, purchase of a second property, etc.).
• – Requires more saving time (prices may rise in the meantime).
• – Slight rate premium possible compared to insured loans.

Conclusion: the “right” down payment is the one that serves your strategy

The question is not only “5% or 20%?” but rather:

• What is your objective: to live in, invest in a plex, build a real estate portfolio?
• What level of debt can you still sleep at night with?
• How long will it take you to reach 20%, and what might happen on the market during that time?

For a first-time buyer, entering the market with a minimum down payment can be an excellent decision if the budget is controlled.

For an investor or a more advanced buyer, going up to 20% (or more) down on a plex or a house can offer substantially greater stability and flexibility.

If you’d like, I can propose a simple calculation structure (a table or simulator) to compare two concrete scenarios: minimum down payment vs 20% for the type of property you’re aiming for.
