Where the Residential Line Ends
In Ontario, properties with four units or fewer are typically financed under residential mortgage rules, while five units or more move into commercial multi-family financing. This shift changes the down payment requirements, interest rate structure, and underwriting approach entirely.
How Lenders Value These Properties
Commercial multi-unit lenders focus heavily on the building's net operating income rather than the borrower's personal income. The debt service coverage ratio, which compares income to debt payments, becomes the central number in the application rather than a personal debt ratio.
CMHC-Insured Options
CMHC offers insured financing options for multi-unit residential buildings that can allow for higher loan-to-value ratios and longer amortizations compared to conventional commercial financing, provided the property and borrower meet the program requirements.
- Higher loan-to-value than conventional commercial
- Longer amortization potential
- Additional program requirements to meet
Documentation for Larger Buildings
Expect to provide a detailed rent roll, operating statements, a property condition assessment, and often an environmental report. Larger, older buildings in Toronto may also need capital expenditure planning to show the lender that major repairs are budgeted for.
Growing Into Larger Buildings
Many investors start with smaller residential properties and work up to five-plus unit buildings once they have more experience and equity. Understanding the commercial underwriting process ahead of time helps you prepare a stronger application when you are ready to make that jump.
Frequently asked questions
- Do I need a bigger down payment for this type of property?
- In most cases yes, since lenders view these properties as carrying more risk than a standard owner-occupied home. The exact amount depends on the property type, the lender, and your overall financial picture, so it is worth getting a clear answer before you start shopping.
- Can I use projected rental income before I have a tenant?
- Some lenders will accept a market rent appraisal or lease commitment for this, while others want to see an existing lease in place. Rules vary quite a bit between lenders, which is one reason it helps to work with a broker who can compare options.
- How long does approval usually take?
- Timelines vary based on the complexity of the file and whether extra documentation like appraisals or building permits are needed. Starting the conversation early, before you are under a tight closing deadline, generally leads to a smoother process.
