Investing in LaSalle
Rental potential in LaSalle
Rental demand is supported by the proximity of the Angrignon metro station, the LaSalle station, the LaSalle Hospital and the Angrignon commercial hub. The rental stock includes numerous duplexes, triplexes and apartment buildings. The district also brings together several hundred businesses, which supports demand for commercial and industrial space. Each building should be analyzed based on its income, its expenses and the condition of its units.

Frequently asked questions
Real estate in LaSalle
What drives rental demand in LaSalle?
Access to the Angrignon metro station and the LaSalle station, the presence of the Hôpital de LaSalle and the businesses of the Angrignon sector attract tenants. However, returns depend on each building and must be calculated case by case.
What is the average price of a plex in LaSalle?
From January to September 2026, 137 plexes (from duplexes to quintuplexes) sold in LaSalle, at an average price of $919,710 (source: Centris®). The right price for a building depends mostly 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 LaSalle?
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.
