Frequently asked questions
Real estate in Dorval
Why invest in Dorval?
The airport, the stations and the highways make it a hub for employment and transportation. Residential, commercial and industrial opportunities are available, and they are analyzed on a case-by-case basis.
What is the average price of a plex in Dorval?
From January to September 2026, 5 plexes (from duplexes to quintuplexes) were sold in Dorval, at an average price of $840,100 (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 Dorval?
For an $800,000 plex, approximately $12,111 according to the City of Dorval’s 2026 scale. 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.
