Minimum down payment (5–10–15% or 20%): what real impact does it have on your mortgage in Quebec?

Minimum down payment (5–10–15% or 20%) : what real impact on your mortgage in Quebec?

You have been saving for years for your Home or your first Residential building… and you’re wondering if it’s really worth waiting to have 20% down payment, or if 5–10–15% is enough.

In Quebec, this choice directly affects: your Morgtage (note: should be Mortgage), your monthly payment, the total interest cost, the insurance premium and even your refinancing flexibility and investment (plex, Multiplex, Commerce, etc.).

Here, clearly, what each level of down payment concretely changes for you.

1. The basic rules of down payment in Quebec

The rules of first-time home buyer loan and mortgage apply to all Canada, so also to Quebec.

1.1. Minimum down payment by price

For a residential property with 1 to 4 units (House, condo, duplex, triplex, quadruplex):

• On the portion of the price up to $500,000
• → 5% minimum (if owner-occupied).
• On the portion between $500,000 and $1.5M
• → 10% minimum on this portion.
• Starting from $1.5M and up
• → No insurance possible: minimum 20% down payment.

These rules mainly concern the first-time buyer and owner-occupiers. For purely rental Residential buildings or a Commercial building, you fall into the world of conventional Financing (20%+).

2. 5–10–15% down payment: “insured” down payment

As soon as your down payment is less than 20%, your mortgage is called insured (CMHC/ SCHL, Sagen or Canada Guaranty).

2.1. Advantages

• Faster access to home ownership
• Ideal for a first-time buyer who hasn’t yet 20% savings.
• Interest rate often lower than some uninsured loans.
• Since late 2024: for some first-time buyers, possibility of 30-year amortization even with less than 20% (subject to program conditions).

2.2. Disadvantages

• You pay an insurance premium on the mortgage added to your Mortgage:
• 90–95% financing (down payment 5–10%): premium around 4% of the loan amount.
• 85–90% (down payment 10–15%): premium approx. 3.1%.
• 80–85% (down payment 15–20%): premium approx. 2.8%.
• This premium increases your mortgage payment and the interest cost over 25–30 years.
• Less refinancing flexibility (because your loan-to-value ratio is higher).

2.3. Concrete impact: 5% vs 10% vs 15%

Without going into exact numbers:

• 5% down payment
• Maximum financing (95%)
• Highest premium
• Higher monthly payment.
• Advantage: you enter your Home sooner.
• 10% down payment
• Lower premium, slightly lower payment.
• You borrow less + lower premium = interest savings over time.
• 15% down payment
• You start to approach the famous 20%
• Premium still lower, lighter payment.
• Easier to refinance later for projects (renos, Investment).

In short: each additional 5% of down payment reduces both:

1. The borrowed amount,
2. The insurance premium,
3. The total interest paid.

3. 20% down payment: the symbolic threshold

At 20% down payment, your Mortgage becomes conventional (uninsured).

3.1. Key advantages

• No insurance premium to pay.
• More maneuvering room for refinancing (for renovations, investments, consolidation, etc.).
• Possibility of amortization up to 30 years with most banks, even if you are not a first-time buyer.

3.2. Possible disadvantages

• You must save longer: the 20% down payment can push your purchase back by several years.
• In a rising market, waiting to reach 20% can cause the price to rise faster than your savings capacity.

For some first-time buyers, a first-time home buyer mortgage with 5–10% down payment can make more sense than waiting for 20%… especially if the rents you currently pay are high.

4. Differences by property type (Single-family home, duplex, Multiplex…)

4.1. Single-family Home, condo, semi-detached

• If you occupy the property:
• 5–10–15% down payment possible (depending on price, up to $1.5M).
• Insured mortgage if < 20%.

4.2. Duplex, triplex, quadruplex (1–4 units)

• Duplex (2 units), owner-occupied
• Down payment as low as 5% (if you live in one of the units).
• Triplex or quadruplex (3–4 units), owner-occupied
• 10% down payment minimum.
• Residential building 1–4 units 100% rental (pure investment)
• Generally 20% down payment minimum, often 25% required by banks.
• Uninsured mortgage or via special rental program, but rarely advantageous to insure at 20% down payment.

Here, the Residential building down payment and the Building down payment are intimately tied to vacancy risk and rental income: the more units (plex, Multiplex), the more the lender wants to see a solid down payment.

4.3. Properties with 5+ units and Commercial / Commerce

From 5 units and up, we talk about a Revenue property or Commercial / Commerce :

• Financing of commercial or multi-family type.
• Common down payment: 20–25% or more.
• Analysis based on the property’s income and expenses (cap rate, ratios, etc.).
• We talk about an Investment strategy rather than personal occupancy.

5. Down payment and refinancing flexibility

The down payment percentage at purchase determines your equity in the property. This equity influences:

1. Future refinancing

• The higher your down payment, the faster your loan-to-value ratio drops below 80%.
• This allows you to refinance for an Investment project, another Residential building, or renovations.

1. Access to a home equity line of credit (HELOC)

• Mortgage lines are usually possible only for conventional loans (20%+ down payment and sufficient equity).

1. Managing interest rate risk

• With a larger down payment, rate increases have less impact on your monthly budget, as your Mortgage balance is lower.

6. First-time buyer: how to choose between 5–10–15% or 20%?

For a first-time buyer aiming for a Home or a small Plex, the question isn’t just mathematical, it’s also strategic.

6.1. When 5–10–15% makes sense

• Rents are already high and buying now stabilizes you.
• You plan to stay in the market for several years.
• You have access to programs like the RAP, a TFSA, etc.
• You want to buy a small Residential building (plex) to occupy one unit and rent the others.

In these cases, accepting the insurance premium on your Mortgage can be a logical investment to enter the market faster.

6.2. When aiming for 20% is wiser

• Your current situation is stable (affordable rent, little pressure to move).
• You aim for a Building or a Residential building for the long term for Investment.
• You want maximum refinancing flexibility and lower payments.
• You are sensitive to total interest costs and want to minimize all charges (including the insurance premium).

In these scenarios, reaching 20% of Home down payment or Building down payment places you in a much more comfortable long-term position.

7. Conclusion: what down payment should you choose for your mortgage in Quebec?

• 5–10–15% down payment
• You pay an insurance premium, but you enter the market faster.
• Often an ideal option for a first-time mortgage on a Home or a small owner-occupied Plex.
• 20% and up
• No insurance, more flexibility, excellent for Investment (Building, Multiplex, Commerce, Revenue property).
• Requires more savings, but reduces the total cost of your Mortgage and eases future refinances.

The right choice depends on your personal situation, your projects (occupancy or Investment), and your risk tolerance.

If you’re unsure between 5–10–15% or 20% down payment, a numbers-based analysis of your scenarios (payments, total cost, borrowing capacity) with a Quebec mortgage broker will let you see in black and white the real impact on your Mortgage… and choose the strategy most aligned with your goals.
