Frequently asked questions
Real estate in Vieux-Longueuil
Is Vieux-Longueuil a good area for a first plex?
There are many duplexes and triplexes, and rental demand is driven by the metro, the cégep, the university campus and the hospital. Still, you need to analyze the condition of the building, the current leases and the work that will need to be done before jumping in. Each building must be assessed on its own income and expenses.
What is the average price of a plex in Vieux-Longueuil?
From January to September 2026, 187 plexes (from duplexes to quintuplexes) sold in Vieux-Longueuil, at an average price of $867,110 (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 Vieux-Longueuil?
For an $800,000 plex, approximately $12,659 according to the City of Longueuil's 2026 table. Plan for this amount in addition to the down payment, which varies depending on the number of units and whether you live in the building.
