Commercial Mortgage Term vs Amortization: Why They're Different and Why It Matters

If you’ve only dealt with residential mortgages, the concept of term and amortization being two different things might seem confusing. On a typical Canadian residential mortgage, the amortization is 25 years and the term is 5 years — but both feel like part of the same structure. The gap between them doesn’t cause much practical concern because residential mortgage renewal is essentially automatic in most cases.

Commercial mortgages are different. The gap between term and amortization is not a technicality — it is one of the most important structural features of commercial lending, and misunderstanding it has cost investors hundreds of thousands of dollars in unexpected costs, forced sales, and lost properties.

This guide explains what term and amortization each mean in the commercial mortgage context, why they’re different, what happens when the term expires, and how to plan your commercial financing strategy around this fundamental structure.

What Is the Mortgage Term?

The term is the contract length — the period during which your specific mortgage agreement is in effect. When the term expires, the mortgage contract ends. The remaining balance becomes due, and you must either renew the mortgage, refinance with the same or different lender, or pay off the remaining balance in full.

Common Commercial Mortgage Terms

Term Length	Typical Use	Availability
1 year	Bridge financing, construction	Banks, credit unions, private lenders
2 years	Short-term value-add, stabilization	Banks, credit unions, alternative lenders
3 years	Medium-hold investors	Most lender types
5 years	Standard commercial term	All lender types — most common
7 years	Longer-hold properties	Institutional lenders, life companies
10 years	Long-term stabilized assets	Life companies, CMHC
15–25 years	Fully amortizing long-term	CMHC programs only

The 5-year term is the standard in Canadian commercial lending, just as it is in residential. However, unlike residential mortgages where 5-year terms represent the overwhelming majority, commercial borrowers have genuine reasons to consider shorter or longer terms depending on their investment strategy.

What the Term Determines

Your mortgage term determines:

• How long your interest rate is locked (for fixed rate mortgages)
• How long your lender relationship is committed — the lender cannot demand repayment during the term unless you breach the agreement
• When you face renewal or refinancing risk — at term end, conditions may have changed
• The basis for prepayment penalty calculations — yield maintenance is calculated against the remaining term
• Your exit flexibility — shorter terms bring renewal sooner but create more frequent transition points

What Is Amortization?

Amortization is the payment schedule calculation — the hypothetical period over which the loan would be fully repaid through regular payments of principal and interest. It determines the size of your monthly payments but does not represent the actual time you’ll hold the mortgage.

How Amortization Affects Payments

Longer amortization periods spread the principal repayment over more years, reducing each monthly payment. Shorter amortizations increase monthly payments but build equity faster.

Example: $5,000,000 mortgage at 5.50% interest rate

Amortization	Monthly Payment	Annual Debt Service	Payment vs 25-Year
15 years	$40,900	$490,800	+38%
20 years	$34,400	$412,800	+16%
25 years	$30,600	$367,200	Baseline
30 years	$28,400	$340,800	-7%
40 years	$26,100	$313,200	-15%
50 years	$25,200	$302,400	-18%

The difference between a 25-year and 40-year amortization on a $5M mortgage is approximately $54,000 per year in reduced debt service. That’s $54,000 more in annual cash flow — money available for operations, distributions, reserves, or reinvestment.

Common Commercial Amortization Periods

Amortization	Availability	Notes
15 years	All lenders	Higher payments, faster equity build
20 years	All lenders	Common for smaller commercial
25 years	All lenders	Standard commercial amortization
30 years	Select lenders	Available from some banks and credit unions
40 years	CMHC only	Available under CMHC standard programs
50 years	CMHC MLI Select only	Available for qualifying affordable/energy-efficient projects

Why Commercial Mortgages Have This Gap

The gap between term and amortization exists because of how commercial lending fundamentally works compared to residential.

The Lender’s Perspective

Commercial lenders don’t want to commit capital for 25 years at a fixed rate. Interest rates change. Property values change. Tenant quality changes. The borrower’s financial situation changes. Local market conditions change. By limiting the term to 5 or 10 years, the lender retains the ability to reassess the deal at renewal — adjusting the rate, modifying the LTV, or declining to renew if conditions have deteriorated.

In residential lending, mortgage default insurance (from CMHC, Sagen, or Canada Guaranty) and a deep secondary market for mortgage-backed securities give lenders comfort extending 25-year amortization with rolling 5-year terms. The residential renewal process is largely automatic because the underlying risk is pooled and insured.

Commercial mortgages are individually underwritten. Each deal is a unique combination of property, tenant, borrower, and market conditions. The lender needs periodic checkpoints to reassess that unique risk profile.

The Borrower’s Perspective

Borrowers want the lowest possible monthly payments (long amortization) with the flexibility to refinance, sell, or restructure (shorter term). The standard 5-year term with 25-year amortization provides a workable balance: manageable payments that support positive cash flow, with a renewal point that isn’t too far away if rates decline or property value increases enough to justify better terms.

What Happens at Term End

This is where the term-amortization gap has real consequences. When your 5-year term expires on a mortgage with 25-year amortization, you still owe approximately 87% to 90% of the original loan amount (depending on the interest rate). That remaining balance is sometimes called the balloon payment — the amount that must be dealt with at term end.

Your Options at Term End

Option 1: Renew with the existing lender. The simplest path. Your lender offers a new term (usually another 5 years) at current market rates. The remaining balance continues to amortize over the remaining amortization period (20 years if you started with 25).

Renewal is not guaranteed. Unlike residential mortgages where renewal is essentially automatic for borrowers in good standing, commercial lenders formally reassess the deal at renewal. They may:

• Require updated appraisals
• Re-examine tenant quality and occupancy
• Review current DSCR against updated rates
• Apply current underwriting standards (which may have tightened)
• Decline to renew if the property or borrower no longer meets their criteria

Option 2: Refinance with a new lender. If your current lender’s renewal terms aren’t competitive — or if they decline to renew — you apply for a new mortgage with a different lender. This is a full application process: new appraisal, new underwriting, new legal and closing costs.

Refinancing makes sense when:

• The property has increased in value, allowing you to pull out equity
• Better rates or terms are available from competing lenders
• You want to change the mortgage structure (e.g., move from conventional to CMHC insured)
• Your current lender is pulling back from commercial lending

Option 3: Pay off the remaining balance. If you have the capital — or if you’ve sold the property — you pay the remaining balance in full. No penalty applies at term end because the mortgage contract has expired naturally.

Option 4: Sell the property. If the property no longer fits your portfolio strategy, term end is a natural exit point. No prepayment penalty applies because the term has expired. You use the sale proceeds to pay off the remaining mortgage balance.

The Balloon Payment Reality

Here is what the remaining balance looks like at the end of a 5-year term for different amortization periods on a $5,000,000 mortgage at 5.50%:

Original Amortization	Remaining Balance After 5-Year Term	% of Original
15 years	$3,625,000	72.5%
20 years	$4,105,000	82.1%
25 years	$4,395,000	87.9%
30 years	$4,570,000	91.4%
40 years	$4,740,000	94.8%

Even with 25-year amortization, after 5 years of payments you’ve only paid down about 12% of the principal. The remaining $4.4M must be dealt with at term end. If you can’t renew or refinance, and don’t have the capital to pay it off, you may be forced to sell the property — potentially at a disadvantage if market conditions have deteriorated.

Renewal Risk Explained

Renewal risk is the possibility that you won’t be able to renew or refinance your commercial mortgage at term end on acceptable terms. This risk is unique to commercial mortgages because residential renewal is rarely denied for borrowers in good standing.

What Creates Renewal Risk

Rising interest rates. If rates have increased significantly since origination, the new rate at renewal increases your debt service. If the higher debt service pushes your DSCR below the lender’s minimum, renewal may be denied or conditional on a principal paydown.

Example:

Scenario	Origination	Renewal
Mortgage balance	$5,000,000	$4,395,000
Interest rate	5.00%	7.00%
Annual debt service (25yr amort)	$349,200	$368,400
NOI	$450,000	$460,000
DSCR	1.29x	1.25x

In this example, the property still qualifies at renewal — but barely. A smaller NOI increase or a larger rate increase could push DSCR below the 1.20x minimum that many lenders require.

Declining property values. If the property’s appraised value has decreased, the existing mortgage balance may exceed the lender’s maximum LTV at current values. The lender may require a principal paydown to bring LTV into compliance.

Deteriorating property condition or occupancy. If vacancy has increased, major tenants have departed, or the property has experienced deferred maintenance, lenders may reassess their risk tolerance. A property that qualified easily at origination may not meet current standards.

Lender policy changes. Lenders periodically adjust their commercial lending appetite. A bank that was aggressively growing its commercial portfolio when you originated may have pulled back by renewal time. If your lender exits the market or reduces exposure to your property type, renewal may not be available regardless of property performance.

Regulatory changes. New capital requirements, stress testing rules, or risk-weighting changes can affect lenders’ willingness and ability to renew commercial mortgages. These systemic changes are outside your control but can impact your renewal.

Mitigating Renewal Risk

Maintain strong property performance. The best protection against renewal risk is a well-maintained property with high occupancy, quality tenants, and growing NOI. Properties that clearly meet lender criteria at renewal rarely face renewal difficulties.

Build reserves. Maintain cash reserves that could fund a principal paydown if required at renewal. A reserve equal to 10% to 15% of the mortgage balance provides a meaningful buffer.

Start the renewal process early. Begin discussions with your existing lender 12 to 18 months before term end. This gives you time to assess options, approach alternative lenders, and negotiate terms without the pressure of an approaching maturity date.

Maintain lender relationships. If you anticipate renewal challenges, proactively communicate with your lender. Lenders prefer borrowers who identify potential issues early over those who present problems at the last minute.

Consider shorter amortization. While longer amortization reduces monthly payments, shorter amortization builds equity faster — reducing the balloon payment and improving LTV at renewal.

How Term Length Affects Rate

Longer terms generally carry higher interest rates. Lenders charge a term premium for the added certainty they provide to borrowers — and the added interest rate risk they absorb.

Typical Term Premium Structure

Term	Approximate Premium Over 5-Year
1 year	-50 to -100 bps (lower)
3 years	-25 to -50 bps (lower)
5 years	Baseline
7 years	+15 to +40 bps
10 years	+25 to +75 bps

Shorter terms offer lower rates but more frequent renewal risk. Longer terms offer higher rate certainty but at a premium. The optimal term depends on your investment horizon and risk tolerance.

A 10-year term at 5.75% versus a 5-year term at 5.50% costs $12,500 per year more on a $5M mortgage — but eliminates renewal risk for an additional 5 years. Whether that premium is worth paying depends on your assessment of future rate and market conditions at the 5-year mark.

How Amortization Affects Monthly Payment and DSCR

Amortization directly drives two critical metrics: your monthly payment amount and your DSCR.

Amortization and DSCR

Longer amortization reduces monthly payments, which increases DSCR. For commercial mortgage qualification, this relationship is crucial.

Example: $4,000,000 mortgage at 5.50%, NOI of $340,000

Amortization	Annual Debt Service	DSCR
20 years	$330,240	1.03x
25 years	$293,760	1.16x
30 years	$272,640	1.25x
40 years	$250,560	1.36x

With 20-year amortization, this deal has a 1.03x DSCR — below virtually every lender’s minimum. At 25 years, the DSCR improves to 1.16x, which meets CMHC minimums but may still fall short for conventional lenders requiring 1.20x+. At 30 years, the deal works for most conventional lenders. At 40-year CMHC amortization, there’s comfortable headroom.

The choice of amortization period can be the difference between your deal qualifying for a commercial mortgage or being declined. Use the DSCR calculator to model how different amortization periods affect your deal’s DSCR before approaching lenders.

The Equity Trade-Off

Longer amortization reduces payments but also slows equity accumulation. After 10 years of payments on a $5M mortgage at 5.50%:

Amortization	Balance After 10 Years	Principal Paid	Equity Built
20 years	$3,035,000	$1,965,000	39.3%
25 years	$3,580,000	$1,420,000	28.4%
30 years	$3,925,000	$1,075,000	21.5%
40 years	$4,300,000	$700,000	14.0%

At 25-year amortization, you’ve built 28.4% equity through principal repayment after 10 years. At 40-year amortization, you’ve built only 14.0%. The monthly cash flow advantage of longer amortization comes at the cost of slower wealth building through mortgage paydown.

CMHC Extended Amortization Benefits

CMHC-insured commercial mortgages offer the longest amortization periods available in Canadian commercial lending — and the impact on deal economics is substantial.

Standard CMHC: 40-Year Amortization

CMHC’s standard multi-family insurance program allows up to 40-year amortization on purchases and refinances. Compared to the 25-year maximum from most conventional lenders, this represents a significant monthly payment reduction.

Impact on a $6,000,000 CMHC mortgage at 5.00%:

Period	25-Year Amort	40-Year Amort	Difference
Monthly payment	$34,860	$29,040	-$5,820/month
Annual debt service	$418,320	$348,480	-$69,840/year
5-year total payments	$2,091,600	$1,742,400	-$349,200 saved

That $69,840 per year in reduced debt service translates directly into improved cash flow and higher DSCR — often making the difference between a deal that works and one that doesn’t.

MLI Select: Up to 50-Year Amortization

The CMHC MLI Select program offers up to 50-year amortization for projects that score high enough on affordability, accessibility, and energy efficiency criteria. At 50-year amortization, monthly payments are further reduced:

Amortization	Monthly Payment on $6M at 5.00%	Annual Savings vs 25-Year
25 years	$34,860	Baseline
40 years	$29,040	$69,840
50 years	$27,540	$87,840

CMHC Term Advantages

Beyond extended amortization, CMHC programs offer longer fixed rate terms than conventional lenders:

• Fixed terms up to 10 years standard
• Terms up to 25 years available on certain programs
• Renewal through CMHC-approved lenders with continuity of insurance

Longer terms paired with longer amortization significantly reduce renewal risk — a CMHC-insured mortgage with a 10-year term and 40-year amortization provides a decade of payment certainty at the lowest available commercial rates.

Interest-Only Periods

Some commercial mortgages offer an initial interest-only period during which no principal is repaid. Monthly payments during this period are significantly lower because you’re paying only interest on the outstanding balance.

How Interest-Only Works

Example: $5,000,000 mortgage at 5.50%

Payment Type	Monthly Payment	Annual Debt Service
Interest-only	$22,917	$275,000
Amortizing (25-year)	$30,600	$367,200
Difference	-$7,683	-$92,200

During the interest-only period, monthly payments are approximately 25% lower than fully amortizing payments. This can be critical for properties in lease-up, renovation, or stabilization phases where NOI is temporarily below stabilized levels.

Common Interest-Only Structures

Structure	Description
IO then amortizing	1–3 years interest-only, then switches to fully amortizing for remainder of term
IO with balloon	Full term is interest-only, entire principal due at maturity
Partial IO	Lower principal payments initially, stepping up over time

Risks of Interest-Only

Interest-only periods build no equity through mortgage payments. If property values decline during the IO period, you may owe more than the property is worth. At the end of the IO period, payments increase substantially when amortization begins. Plan for this payment jump in your cash flow projections.

Fully Amortizing vs Partially Amortizing

Fully Amortizing Mortgages

A fully amortizing mortgage is one where the term equals the amortization — the mortgage is completely paid off through regular payments, with no balloon payment at the end. These are rare in conventional Canadian commercial lending but available through CMHC for terms of 15 to 25 years.

Advantages:

• No renewal risk — the mortgage is paid in full at term end
• No balloon payment to manage
• Complete certainty of debt obligations over the full period

Disadvantages:

• Limited to CMHC-insured multi-family in the Canadian market
• Longer fixed rate commitment may carry a term premium
• Defeasance penalties if you need to exit early

Partially Amortizing Mortgages

The vast majority of Canadian commercial mortgages are partially amortizing — meaning the term is shorter than the amortization, resulting in a balloon payment at term end. A 5-year term with 25-year amortization is partially amortizing because only 5 years of the 25-year payment schedule are completed before the term expires.

This is the standard structure, and it works well when borrowers understand and plan for the balloon payment at term end.

Strategies for Managing Term-End Risk

Strategy 1: Stagger Term Expirations

If you hold multiple commercial properties, avoid having all mortgages mature in the same year. Stagger terms so that you face renewal on one or two properties at a time rather than your entire portfolio simultaneously. This reduces the concentration of renewal risk in any single year.

Strategy 2: Build a Cash Reserve Fund

Set aside a portion of property cash flow into a reserve fund specifically designated for potential principal paydowns at renewal. If renewal requires a paydown, the reserve fund is available. If not, the fund continues to grow as a safety net.

Strategy 3: Choose the Right Term for Your Strategy

Match your term to your intended hold period:

• Value-add with 2–3 year repositioning: Consider a 3-year term
• Buy-and-hold with 10+ year horizon: Consider a 7 or 10-year term
• Uncertain hold period: The standard 5-year term provides flexibility

Strategy 4: Negotiate Renewal Rights

Some commercial mortgage agreements include guaranteed renewal provisions — the right to renew at term end at the lender’s then-current rates. While the rate isn’t locked, the renewal itself is guaranteed, eliminating the risk of the lender declining to renew.

These provisions are more commonly available from credit unions and portfolio lenders than from chartered banks. They are worth negotiating at origination, even if they carry a small rate premium.

Strategy 5: Maintain Maximum LTV Headroom

The more equity you have in the property at renewal, the less likely you are to face LTV challenges. Strategies that maintain headroom include:

• Choosing shorter amortization (faster equity build)
• Making periodic lump-sum principal payments during the term
• Investing in property improvements that increase appraised value
• Maintaining strong NOI that supports favourable cap rate valuations

Strategy 6: Use CMHC for Maximum Protection

Multi-family mortgage financing through CMHC provides the most comprehensive protection against term-end risk. Extended amortization (40–50 years), longer available terms (up to 25 years), and lower rates all reduce the probability and severity of renewal challenges. If your property qualifies for CMHC insurance, it’s almost always the optimal choice from a risk management perspective.

Working With a Broker to Navigate Term and Amortization

A mortgage broker experienced in commercial mortgage financing can help you navigate the term-amortization decision by:

• Modeling multiple term and amortization scenarios against your property’s financials
• Identifying lenders that offer extended amortization, interest-only periods, or guaranteed renewal provisions
• Structuring the mortgage to minimize renewal risk based on your investment timeline
• Advising on CMHC eligibility and the benefits of insured financing for multi-family
• Comparing current commercial mortgage rates across different term lengths to assess the term premium

Frequently Asked Questions

What happens if I can't renew or refinance my commercial mortgage at term end?

If you cannot renew with your existing lender, refinance with a new lender, or pay off the remaining balance, you face a potentially serious situation. The lender may grant a short-term extension (typically 3 to 6 months) to allow more time for refinancing. If no solution is found, the lender can demand full repayment, and failure to pay constitutes default. In practice, most lenders prefer to work with borrowers to find a solution rather than enforce default — forced sales and power of sale proceedings are costly for lenders too. However, the borrower’s negotiating position weakens significantly at maturity. This is why planning for term end should begin 12 to 18 months before maturity.

Can I get a 30-year amortization on a conventional commercial mortgage in Canada?

Yes, though it’s less common than 25-year amortization. Some chartered banks and credit unions offer 30-year amortization on commercial mortgages for strong borrowers with stabilized properties. The extended amortization reduces monthly payments and improves DSCR. For amortization beyond 30 years (40 or 50 years), you need CMHC-insured financing, which is limited to multi-family residential properties with 5 or more units.

Does the amortization reset when I renew my commercial mortgage?

Typically, the amortization continues from where it left off — it does not reset. If you started with a 25-year amortization and renew after a 5-year term, the remaining amortization is 20 years. However, some lenders will allow you to re-amortize at renewal — extending the amortization back to 25 years. Re-amortization reduces your monthly payments but means you’ll take longer to pay off the mortgage and will pay more total interest. Whether re-amortization is available depends on the lender’s policies and the property’s current LTV and DSCR.

Is the balloon payment at term end a penalty?

No. The balloon payment is not a penalty — it’s simply the remaining mortgage balance that hasn’t been repaid through regular payments. It exists because the term is shorter than the amortization period. If you renew or refinance, the balloon payment is rolled into the new mortgage. It only becomes a cash requirement if you can’t renew or refinance and must pay the remaining balance out of pocket or through a property sale.

Should I choose a shorter amortization to build equity faster?

It depends on your priorities. Shorter amortization builds equity faster and reduces the balloon payment at term end, but it increases monthly payments and reduces cash flow. If your property generates strong NOI with comfortable DSCR, shorter amortization accelerates wealth building. If DSCR is tight or you need maximum cash flow, longer amortization preserves operating flexibility. Many investors prioritize cash flow (longer amortization) during the acquisition phase and switch to shorter amortization when the portfolio is generating surplus cash.

Can I make lump-sum payments against a commercial mortgage?

This depends on your specific mortgage agreement. Some commercial mortgages include prepayment privileges that allow annual lump-sum payments (typically 10% to 20% of the original balance) without penalty. Others are fully closed, meaning any principal payment beyond the regular scheduled amount triggers prepayment penalties. Negotiating prepayment privileges at origination is important, particularly for variable rate mortgages where the penalty for full prepayment (three months’ interest) may make partial prepayment privileges less critical.

What is the longest term available for a commercial mortgage in Canada?

The longest fixed-rate terms available are through CMHC-insured programs, which offer terms up to 25 years. Some CMHC programs even offer fully amortizing mortgages where the term equals the amortization (e.g., 25-year term with 25-year amortization). Conventional commercial lenders typically cap terms at 10 years, with 5 years being the standard. Life insurance companies occasionally offer 15-year terms for institutional-quality assets.

Understanding the Structure Before You Sign

The relationship between term and amortization is the structural backbone of every commercial mortgage. Getting it right means your payments are manageable, your cash flow is predictable, and you’re prepared for what happens when the term expires. Getting it wrong means surprises at renewal that can force costly refinancing, principal paydowns, or even property sales at inopportune times.

Before signing any commercial mortgage commitment, understand exactly what your balloon payment will be at term end, what renewal looks like, and what happens if conditions change. Model multiple scenarios. Build reserves. Start renewal planning early. And match your term and amortization to your actual investment strategy — not to a generic template.
