Investing in Rental Real Estate in Montreal

Montreal is a prime city for rental real estate investment in Canada. Plex buildings (duplex, triplex, fourplex) are abundant, rental yields are competitive, and rental demand remains strong. However, financing an income property differs significantly from a primary residence.

Anthony King, AMF-certified mortgage broker in Montreal, works regularly with real estate investors. This guide covers rental income qualification methods, down payment requirements, and the major differences between lenders that can impact your borrowing capacity by tens of thousands of dollars.

Plex Investing: The Montreal Specialty

The plex is a property category uniquely Montreal. Duplexes, triplexes, and fourplexes represent a significant portion of the city’s housing stock. For investors, the plex offers a unique advantage: the ability to live in one unit while renting the others to reduce or cover housing costs.

Owner-Occupied Duplex

You live in one unit and rent the other. 5% down payment possible with CMHC insurance. Rental income is used in mortgage qualification.

Owner-Occupied Triplex

You live in one unit and rent the other two. Same 5% down payment possible. Better yield ratio with two sources of rental income.

Owner-Occupied Fourplex

Maximum of 4 units to remain in residential financing. Beyond 4 units, you enter commercial financing with different rules.

Non-Occupant Plex (Pure Investment)

Minimum 20% down payment. Rental income is still used in qualification, but conditions are stricter.

Rental Income Qualification Methods

How rental income is integrated into your borrowing capacity calculation varies considerably from lender to lender. This is often WHERE the choice of lender makes the biggest difference for an investor.

MethodCalculationImpact on Qualification
Offset MethodRental income is subtracted from the property’s expenses before GDS/TDS ratio calculationGenerally more favorable. Reduces the property’s impact on your debt ratios.
Add-Back MethodA percentage of rental income (often 50% to 80%) is added to your gross incomeDirectly increases your qualifying income. Particularly favorable for high-yield properties.

The difference between the two methods can represent a 10% to 15% gap in your TDS ratio. In concrete terms, this can mean the difference between approval and rejection, or between a fourplex and a duplex.

With 14 lenders using different rental income calculation methods, Anthony King identifies the lender that maximizes your investment capacity.

Down Payment for Rental Properties

Down payment requirements depend on whether you will occupy the property:

ScenarioMinimum Down PaymentInsurance
Owner-Occupied (1-4 units)5%CMHC required (under 20%)
Non-Occupant (1-4 units)20%None (conventional mortgage)
5+ unitsVariable (commercial financing)Not applicable

The owner-occupant strategy on a plex is the most advantageous way to start: reduced down payment, access to CMHC insurance, and rental income improves your qualification.

Strategy: Live in One Unit, Rent the Others

The most popular strategy in Montreal for beginning investors: purchase an owner-occupied plex. You live in one unit and rent the others. Rental income covers a significant portion (sometimes all) of your mortgage payment.

Tax advantages: expenses related to the rental portion of the building are tax-deductible (proportional mortgage interest, property taxes, insurance, repairs). Upon resale, only the rental portion is subject to capital gains tax.

Frequently Asked Questions

What is the minimum down payment for a rental property in Montreal?

If you occupy one of the units, the minimum down payment is 5% (up to 4 units) with CMHC insurance. For a non-occupant property, the minimum is 20%. Beyond 4 units, commercial financing rules apply.

How is rental income factored into mortgage qualification?

Depending on the lender, rental income is either subtracted from the property’s expenses (offset method) or added to your gross income (add-back method, generally 50% to 80% of rental income). The difference between the two methods can represent a significant gap in your borrowing capacity.

Can a first-time buyer purchase a plex in Montreal?

Yes. A first-time buyer owner-occupant can purchase a plex (up to 4 units) with 5% down. They also have access to 30-year amortization (since December 2024), HBP, and FHSA. It is a powerful starting strategy for building wealth.

How many rental properties can I finance?

There is no legal limit, but borrowing capacity is capped by your debt service ratios. Each additional property affects your GDS/TDS ratios. Some lenders cap at 4-5 properties in their portfolio, others have no such restriction. Anthony King identifies the lenders most open to multi-property portfolios.
