Depreciation 30 years vs 25 years in Quebec: which one to choose for your mortgage?

30-year vs 25-year Amortization in Quebec: which to choose for your mortgage?

Are you hesitating between a 25-year or 30-year amortization for your mortgage? In Quebec, this choice influences not only your monthly payments, but also your qualification ability, the total cost of the Mortgage, and even your Investment strategy if you’re buying a multiplex / plex, a Residential Building or a Commercial property.

With the arrival of new measures allowing first-time buyers to obtain a 30-year amortization even with less than 20% down, the question is more relevant than ever.

1. Amortization: 25 years vs 30 years – basics recap

Amortization = theoretical total duration to repay your Mortgage (e.g., 25 or 30 years).

Not to be confused with the term (e.g., a 5-year renewable term).

• 25 years :
• Standard for a CMHC-insured mortgage (down payment < 20%).
• Less total interest paid.
• Higher monthly payment.
• 30 years :
• Possible for conventional mortgages (down payment ≥ 20%) for a long time.
• Now also possible for some first-time buyers with less than 20% down, under conditions (CMHC insurance, premium surcharge, program rules).
• Lower monthly payment, but more interest over the term.

2. Concrete impact on your payment and your interest

Without getting into complex calculations, here’s what happens in practice when you lengthen the amortization from 25 to 30 years:

1. Monthly payment: decreases by about 8 to 12%

• For the same amount of House or Residential Building, you pay less each month with 30 years.
• This helps your monthly budget (household, family, projects, renovations).

1. Total interest cost: significantly higher

• You pay interest for 5 more years.
• Over the duration, the difference often amounts to tens of thousands of dollars.

1. Mortgage qualification

• A 30-year amortization reduces the payment used in debt ratio calculations.
• Result:
• You can sometimes borrow a bit more.
• Or pass the qualification you would fail with a 25-year term.

1. Interest rate and CMHC premium

• Depending on the lender, a 30-year amortization can sometimes be associated with a slightly higher rate.
• For a first-time home buyer mortgage insured (less than 20% down), a 30-year amortization implies a higher CMHC premium (e.g., a premium surcharge of about 0.2% of the premium) – this cost is added to your Mortgage.

3. First-time buyer: 25 years or 30 years for your Home?

For a first-time buyer, the decision isn’t just a math problem, but also one of financial security.

Advantages of 30 years for a first-time buyer

• More affordable payment :
• You reduce your monthly payment – often the difference between “I can buy” and “I must wait.”
• Better wiggle room :
• Easier to manage surprises: childcare, car, home maintenance, tax increases, etc.
• Simpler qualification :
• Useful in a context where interest rates and the stress test limit borrowing capacity.

Disadvantages of 30 years for a first-time buyer

• Significantly more interest over the term :
• You pay more overall for the same property.
• Slower principal repayment :
• Your equity in the Home grows more slowly.
• Higher CMHC premium (if < 20% down) :
• Your first-time home buyer mortgage insured costs more.

When 30 years makes sense for a first-time buyer

• Tight monthly budget, but stable situation.
• You absolutely want to buy now (family, school, proximity to work).
• You plan to make prepayments later (increase your payments, make lump-sum payments when your income rises).

When 25 years is often preferable

• Your budget already allows 25-year payments.
• You are aiming for a quicker retirement of your Mortgage.
• You are comfortable with a higher payment in exchange for tens of thousands of dollars in interest saved.

4. Investor: Building, multiplex, plex, Commercial – what to choose?

For an investor in real estate (multiplex, plex, Residential Building, small Commercial building), the logic is a bit different: it’s about yield and cash flow.

Advantages of 30 years for an investor

• Lower mortgage payment = better cash flow
• Rentals more easily cover the mortgage payment, taxes, insurance, and maintenance.
• Easier to pass the qualification ratios required by banks, especially on a Residential Building or a plex where rental income is key.
• Real estate leverage effect
• By reducing the payment, you can sometimes buy a larger building (e.g., move from a duplex to a quadruplex) or multiply acquisitions.

Disadvantages of 30 years for an investor

• More interest = reduced net yield
• Over a 20–25 year horizon, the additional interest reduces the portion of yield that comes to you.
• Capital repaid more slowly
• You build your equity more slowly, which can delay refinancings for other projects (financing new acquisitions, major renovations, etc.).

For an investor, the right reflex

• Often use the 30 years to maximize flexibility and cash flow.
• Then, as soon as cash flow allows, accelerate the repayment:
• Accelerated payments.
• Annual lump-sum payments with surplus rents.

Thus, you maintain the security of a low payment, while effectively shortening your amortization to around 20–25 years.

5. CMHC rules, down payment and amortization: what to keep in mind

In Quebec, as elsewhere in Canada, your down payment and the type of property (House, Residential Building, plex, Commercial) directly influence amortization options:

• Residential property 1 to 4 units, down payment < 20%
• Insured mortgage (CMHC or equivalent).
• Standard amortization: 25 years.
• Some recent programs for first-time buyers allow a 30 years, but with conditions and a higher premium.
• Residential building 1 to 4 units, down payment ≥ 20%
• Uninsured (conventional) mortgage.
• Amortization possible up to 30 years depending on the lender.
• 5 or more units / Residential commercial building / Commercial building
• Financing of a commercial type.
• Amortization often 25 to 30 years, sometimes more depending on the project, rent stability, etc.
• We’re then talking about specialized commercial financing, with its own criteria (detailed income and expense analysis, vacancy rate, reserve funds, etc.).

6. How to choose between 25-year and 30-year amortization?

Here's a simple method to decide.

1. First look at the 25-year payment

Ask for the calculation for a mortgage with a 25-year amortization:

• Is this payment manageable within your budget (including taxes, heating, condo fees, maintenance)?
• Keep a good safety margin: you must be comfortable if expenses rise.

If the answer is yes:

• Prioritize 25 years : you save a lot of interest and build equity faster.

2. If 25 years is too tight, compare with 30 years

Then have the same financing calculated in 30 years:

• How much does the payment drop?
• Does this drop give you real comfort (not just “I get through the bank”, but also “I sleep well at night”)?

If the answer is yes:

• Take the 30 years, but commit mentally to:
• Increase your payments as soon as possible.
• Use the prepayment privileges (15–20% per year at several lenders).

3. Think about your horizon

• Do you plan to stay in this Home or this Residential Building for less than 7–10 years?
• The 25 vs 30-year choice will mainly impact your cash flow and your ability to hold up if rates rise on renewal.
• Do you plan to keep the building for a very long time (long-term Investment strategy)?
• The interest savings over 25 years become very meaningful.
• The 30-year with accelerated payments option can offer a middle ground.

7. Conclusion: 30 years to breathe, 25 years to save

In short:

• Amortization 25 years
• Ideal if your finances are already solid.
• Less interest, faster principal repayment.
• Excellent option for a first-time buyer who wants to free themselves from their Mortgage sooner.
• Amortization 30 years
• A powerful tool to make the payment affordable and improve qualification.
• Very useful for a tight budget, a first-time home buyer mortgage, or an Investment project (multiplex, plex, Residential Building, commercial building) where cash flow is a priority.
• Use with discipline: first take advantage of the lower payment, then accelerate the repayment as soon as possible.

The best choice isn’t the same for everyone. It depends:

• On your income and the stability of your situation.
• On your risk tolerance and rate fluctuations.
• On your long-term objectives (security, retirement, growth of your real estate portfolio, etc.).

The important thing is to understand that amortization is a strategic lever for your Financing, not just a number in a contract. By adjusting your amortization – and by using intelligently the prepayment privileges – you can tailor your Mortgage to your reality, whether you’re buying your first Home or your next Residential Building.
