Frequently asked questions
Real estate in Châteauguay
What drives rental demand in Châteauguay?
The size of the city, the presence of the Hôpital Anna-Laberge, the shops and the buses to Montreal. The housing stock includes both plexes and multi-unit buildings.

From January to September 2026, 14 plexes (from duplexes to quintuplexes) were sold in Châteauguay, at an average price of $607,214 (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.
