Investing in Saint-Laurent
Rental potential in Saint-Laurent
The large number of jobs, the two cégeps and the arrival of the REM stations support rental demand. The rental stock includes plexes, apartment buildings and many condos, while the commercial and industrial market is particularly active thanks to the Technoparc and the business parks. Each project should be analyzed case by case, based on income, expenses and the condition of the building.
How we analyze a plex

The asking price compared with the building's income and with plexes sold in the area.

Comparable sales
Plexes recently sold in Saint-Laurent and the surrounding area, and the price per door, adjusted for the condition of the building.

Frequently asked questions
Real estate in Saint-Laurent
What drives rental demand in Saint-Laurent?
The many jobs at the Technoparc and the business parks, the presence of the Cégep de Saint-Laurent and Vanier College, as well as the metro and the REM, attract tenants. Returns depend on each building and should be verified case by case.
What is the average price of a plex in Saint-Laurent?
Over January to September 2026, 60 plexes (from duplexes to quintuplexes) sold in Saint-Laurent, at an average price of $916,700 (source: Centris®). The right price for a building depends above all on its income: always compare the multiplier and the condition of the building.
How do you calculate the return on a revenue property?
Start with the gross income multiplier (price ÷ annual income), then calculate net income: rents minus taxes, insurance, energy, maintenance and vacancy. Then compare with similar buildings sold in the area. A good purchase is judged by actual income, not expected income.
What should you check in the leases before buying a building?
Ask for a copy of every current lease and renewal notice: rent, term, services included, special agreements. Compare the rents with the market in the area and check for vacant units. Leases stay with the building: the buyer takes them on as they are.
How much is the welcome tax on a plex in Saint-Laurent?
For an $800,000 plex, roughly $11,349 based on the City of Montreal's 2026 schedule. Plan for this amount on top of your down payment, which varies depending on the number of units and whether you live in the building.
