The multiplex financing path
Financing changes with the number of units, occupancy plan and how the lender recognizes rental income.

Detailed guide
The 4-Unit Threshold
In Canada, properties with 1-4 units are classified as residential and can be financed with standard residential mortgage programs. Properties with 5+ units are classified as commercial and require commercial underwriting. This distinction has a massive impact on your down payment, rates, and qualification criteria.
For one-to-four-unit properties, residential mortgage rules may apply. Five or more units are generally assessed through commercial underwriting. Required equity and qualification treatment depend on the occupancy, property, insurer, and lender program.
How Rental Income Helps You Qualify
Rental income may help support qualification, but lenders use different methods, documentation, vacancy allowances, and expense assumptions.
Use current leases, market-rent evidence, and the selected lender’s calculation before relying on rental income in a financing plan.
Down Payment and Rate Guide
The financing route usually depends on these categories:
- Owner-occupied two-to-four units: insurer and lender rules depend on unit count, use, value, and borrower qualification.
- Rental two-to-four units: investor equity and rental-income calculations vary by lender and program.
- Five or more units: commercial underwriting generally focuses on NOI, DSCR, property quality, and sponsor strength.
- Larger multi-family: conventional or insured commercial programs may be considered when the property and borrower meet current eligibility rules.
Why Multiplexes Are a Smart Strategy
Multiplexes offer diversified rental income (if one unit is vacant, you still have income from the others), potential for house-hacking (live in one unit, rent the rest), and value-add opportunities through renovations and rent increases. In BC’s expensive market, they are one of the most accessible paths to building a real estate portfolio.
