Frequently asked questions
Real estate in Saint-Lambert
Are there investment opportunities in Saint-Lambert?
The supply of plexes is scarcer than elsewhere on the South Shore, but rental demand is supported by the train station, Collège Champlain and the proximity to Montreal. The commercial spaces on avenue Victoria also interest some investors. Each opportunity should be analyzed based on its actual income and its condition.
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-Lambert?
For an $800,000 plex, approximately $14,611 according to the City of Saint-Lambert’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.
How can you increase the value of a revenue property?
Reduce vacancy, maintain the units and common areas, improve energy efficiency and keep a clear record of income and expenses. Rent increases must comply with the rules of the Tribunal administratif du logement.
