A commercial mortgage is financing intended for commercial real estate or a business-related property purpose. It may be relevant when you are buying a property where your business operates, acquiring income-producing real estate, or refinancing another commercial asset.
The right structure depends on more than the amount you want to borrow. Property use, ownership structure, business and property income, available equity, documentation, repayment preferences, and lender assessment all matter.
What is a commercial mortgage?
A commercial mortgage is a loan used to purchase or refinance commercial real estate or support a business-related property transaction. This may include a property used by an operating business, a property held to generate rental income, or another asset whose purpose differs from a typical owner-occupied home.
The term describes a financing category, not one universal product. Lenders may evaluate the same transaction differently. The available structure can depend on the property, borrower, intended use of funds, and the strength and predictability of the income supporting repayment.
Commercial financing may therefore be relevant to a business owner buying a location, an investor purchasing an income-producing property, or an owner refinancing an existing commercial asset. MiiGrowth identifies commercial mortgages and commercial property financing among its services for borrowers in Mississauga and Southern Ontario.
Commercial mortgages vs. residential mortgages
The distinction is driven primarily by the transaction and property context. Loan size alone does not determine the category. A residential property used as a personal home is assessed differently from a commercial building, even if the requested financing is similar.
| Area | Residential financing | Commercial financing |
|---|---|---|
| Purpose | Usually supports a personal residence. | Supports commercial real estate or a business-related property purpose. |
| Property use | Typically focuses on personal occupancy. | May involve business operations, leasing, investment income, or mixed uses. |
| Underwriting | Often centres on household income, credit, and the residential property. | May consider the borrower, business, property performance, leases, and commercial purpose. |
| Income analysis | Usually emphasizes employment or self-employment income. | May include business income, rental income, leases, operating performance, and personal income. |
| Documentation | Typically includes personal identification, income, assets, debts, and property details. | May require additional business, ownership, property, and financial records. |
| Structure | May follow a standard residential mortgage format. | Terms, security, repayment, renewal, and exit planning may vary by transaction. |
This is a starting point rather than a universal lender rule. Mixed-use properties, unusual buildings, and investment arrangements require case-specific review.
When might commercial financing apply?
Buying or refinancing commercial real estate
If the property itself is commercial, financing may need to account for its use, condition, income potential, tenancy, and ownership structure. A purchase and a refinance may also have different objectives, such as acquiring the asset, replacing existing financing, funding improvements, or accessing equity.
Buying the property where your business operates
A business owner may seek financing to purchase the building or unit used for business operations. The application may need to explain how the premises will be used, how the business generates income, and how proposed payments fit the operating plan.
Financing an investment or income-producing property
Investment property financing requires a close look at the relationship between the asset and its expected income. Rental arrangements, vacancies, expenses, ownership, and the investor’s broader financial position may affect the review. An investment property does not automatically require a commercial mortgage.
Readers considering this type of transaction can review investment property financing as an initial resource. The appropriate option still depends on the specific property and borrower profile.
What can shape the mortgage structure?
Before comparing lenders, clarify the transaction’s purpose. Are you buying, refinancing, consolidating existing financing, improving the property, or releasing equity? A precise purpose helps a mortgage professional understand the amount, timing, security, and repayment plan that may be appropriate.
- Property purpose and condition: Explain whether the property is owner-occupied, leased, mixed-use, or intended for a change in use.
- Borrower and ownership structure: Identify the people, company, partnership, or other entity that will own or borrow.
- Business and personal income: Explain how repayment will be supported, including business financial information, personal income, and existing obligations.
- Property income: For an income-producing asset, organize leases, rent, expenses, vacancies, and operating performance where applicable.
- Equity or down payment resources: Document available funds and identify whether other assets or properties form part of the plan.
- Repayment preferences: Consider payment predictability, flexibility, prepayment options, and term length.
- Exit strategy: Decide whether repayment will come from a sale, refinance, stabilized income, or another realistic plan.
Rates, fees, amortization, debt-service calculations, documentation standards, and approval requirements vary by lender and transaction. Treat any initial estimate as conditional until the property and application have been reviewed.
Information to organize before applying
The final document list depends on the lender and transaction, but the following information can make the first conversation more productive.
Property information
- Address, property type, intended use, and purchase or refinance details
- Purchase agreement, current mortgage information, or other financing records
- Appraisal, valuation, inspection, zoning, or environmental information if available or requested
- Lease agreements, rent details, operating statements, and expenses for an income-producing property
- Planned renovations, construction, expansion, or changes in use
Borrower and business information
- Identification and contact details for borrowers, guarantors, owners, and relevant entities
- Business registration and ownership information where applicable
- A concise description of the business, its operating history, and how the property supports it
- Personal and business assets, liabilities, existing loans, and other obligations
Financial and transaction information
- Recent financial statements, tax information, bank records, or other relevant income documentation
- Amount requested, available funds, intended use of proceeds, and expected closing timing
- An explanation of how payments will be made and the longer-term repayment plan
Having these materials does not guarantee approval, and every lender will not request every item. The goal is to present a coherent picture so requirements can be confirmed early.
Questions to ask before choosing financing
- How is the proposed financing structured, and why does it fit the property and its use?
- What costs apply beyond the interest rate, including lender, valuation, legal, or other transaction costs?
- How are payments calculated, and could they change during the term?
- What prepayment, refinancing, renewal, or discharge conditions apply?
- What security or guarantees may be required?
- Which assumptions about rent, business income, occupancy, or property value are being used?
- Which documents remain outstanding, and who is responsible for obtaining them?
- What is the realistic exit strategy if a sale, refinance, or income target takes longer than expected?
These questions help you compare practical fit instead of choosing solely on an advertised rate. They can also reveal assumptions to review with your accountant, lawyer, or another adviser.
Should you approach a bank or a commercial mortgage broker?
A bank may be a sensible starting point when you have an established relationship and a straightforward transaction that fits its lending approach. A commercial mortgage broker may be useful when the property, ownership structure, income picture, or documentation is more complex.
A broker does not remove the need for underwriting, due diligence, or careful comparison. Ask about licensing, relevant experience, lender channels, communication expectations, compensation, and any costs you may be responsible for.

A note for borrowers in Ontario
Ontario’s official legislative review states that reducing red tape for commercial mortgage transactions was fully implemented as of 2022. This does not establish a universal rate, approval standard, minimum contribution, or borrower outcome. Confirm current requirements and obligations for your transaction with the relevant licensed professionals. Read the Ontario legislative review.
Frequently asked questions
Can a business owner use a commercial mortgage to buy the property where the business operates?
Yes, that can be a potential use of commercial financing. The application would need to connect the property to the business purpose and explain the business’s financial capacity, ownership structure, and repayment plan.
Does an investment property always require a commercial mortgage?
No. The answer can depend on the property’s use, units, ownership structure, rental income, and lender criteria. Classification should be confirmed rather than assumed.
What should I ask about the exit strategy?
Ask how the balance is expected to be repaid or refinanced, which assumptions support that plan, and what happens if a sale, refinance, or income target takes longer than expected.
Can a mortgage broker help compare commercial financing in Southern Ontario?
A broker may help identify relevant financing conversations, organize application information, and compare available structures. Ask how the broker is compensated and whether recommendations reflect the full cost and terms.
How to decide your next step
Identify the property’s purpose, borrower or ownership structure, amount and use of funds, and income supporting repayment. Then gather relevant property, business, and financial information before comparing commercial mortgage options. Mixed-use, income-producing, corporate-owned, or complex transactions may benefit from personalized advice.
