The price per door (sale price divided by the number of units) is $320,000 per unit in median, half of sales between $275,750 and $410,750 (191 plexes of 2 to 6 units). The gross rent multiplier (price divided by declared potential gross revenue) is 17.7 in median over 192 listings, for a median potential gross revenue of $50,520 a year. The price per door is the quick way to compare a duplex with a fourplex; the multiplier says how many years of gross rent you are paying. The higher the multiplier, the more you pay for location and expected appreciation, and the less the rents cover the mortgage.

Take the median triplex of the last 12 months, $921,250. Owner-occupied, it can be financed with a minimum down payment of $92,125 (10%, the CMHC rule for 3 and 4 units), a CMHC premium of 3.10% added to the loan ($25,703) and an insured loan of $854,828; at the 4.29% 5-year fixed rate posted by Multi-Prêts on September 14, 2026 over 25 years, the payment is about $4,632 a month, and the lender qualifies you at the 6.29% stress-test rate ($5,617 a month). Not owner-occupied, the down payment is 20% ($184,250) with no premium, for a payment of about $3,993 a month at the same rate ($4,843 at the stress-test rate).
The median potential gross revenue declared on plexes sold in LaSalle is $50,520 a year ($4,210 a month, 192 listings), for a median gross rent multiplier of 17.7 (price divided by gross revenue). Before municipal and school taxes, insurance, maintenance, vacancy and the unit you occupy, those rents cover 91% of the example's insured mortgage payment: a plex in LaSalle is bought to live for less and build equity, not to pocket a surplus in year one. Our page plex return in Montreal does the full calculation, line by line.
LaSalle sells post-war duplexes and triplexes along Newman Boulevard, Dollard Avenue and Centrale Street, with the riverfront (LaSalle Boulevard, the Lachine Rapids) and the Parc des Rapides as the premium; four- to six-unit buildings are common near Carrefour Angrignon and the Angrignon station. A LaSalle plex compares with Lachine and mainland Verdun, with larger units and parking.

Over the last 12 months (September 16, 2025 to September 16, 2026), the median income property sold in LaSalle on Centris went for $910,000 (half of sales between $815,000 and $1,000,000, 193 sales); duplex $837,000; triplex $921,250; fourplex $985,000; five-unit building $1,145,000.

Owner-occupied: 5% of the first $500,000 and 10% of the rest for a duplex, 10% for a triplex or a fourplex, with the CMHC premium added to the loan (4.00% at 95% loan-to-value, 3.10% at 90%), as long as the price is under $1,500,000 (CMHC rules read September 16, 2026). Not owner-occupied, 20% minimum, no premium.
The sale price divided by the number of units: $320,000 per unit in median over the last 12 months in LaSalle (half of sales between $275,750 and $410,750, 191 plexes of 2 to 6 units). It is the fastest benchmark to compare a duplex with a fourplex; rents and condition then correct it.
The median gross rent multiplier in LaSalle is 17.7 over the last 12 months (192 listings with declared revenue): at that level, rents cover part of the mortgage payment, not all of it, unless the down payment is large. The return is judged on net income (rents minus taxes, insurance, maintenance, vacancy, interest at today's rate), on the sector's appreciation (the median plex rose 79% between 2016 and 2025) and on the unit you stop renting.
