What is a door worth in Trois-Rivières? Not an impression: the price per unit and the rent multiplier calculated on every plex sold in 12 months, by number of units and by year built.
As of September 22, 2026, on 284 plex sales in Trois-Rivières read on Centris between September 16, 2025 and September 16, 2026, the median price per door is $173,417 and the median gross rent multiplier (GRM) is 14.6x: a buyer pays 14.6 times the building's annual gross revenue. The median plex sold for $460,000 in 9 days, with 3 units. On the medians, that works out to roughly $11,878 of gross revenue per door per year, or $990 per month. Trois-Rivières ranks 15th of 20 cities for price per door and 4th of 20 for GRM, from cheapest to most expensive relative to revenue. Source: Centris (Matrix), sales of income properties (duplexes, triplexes, fourplexes and buildings of 5 units and more) closed between September 16, 2025 and September 16, 2026, sold price, residential units and potential gross revenue as declared on each listing, up to 300 sales per city, compiled September 22, 2026, aggregates only.
Every income property sold on Centris declares its price, its number of units and its potential gross revenue. On 284 sales in Trois-Rivières in 12 months, the median price is $460,000 for a median building of 3 units, which gives $173,417 per door. The median plex found a buyer in 9 days.
The figure an investor looks at first is the gross rent multiplier, the GRM: the price paid divided by the building's annual gross revenue. In Trois-Rivières, it is 14.6x. In other words, half the buyers paid less than 14.6 times the annual rents, the other half more. The lower the GRM, the faster the rents cover the price. Across the 20 cities tracked, it runs from 12.3x in Saguenay to 17.9x in Laval; Trois-Rivières ranks 4th.
Crossing the two medians, a door in Trois-Rivières brings in on the order of $11,878 per year, or $990 per month. That is an order of magnitude computed on medians, not a guaranteed rent: the actual rent of each unit is in the lease.
| Building type | Sales | Median sale price | Price per door | GRM (price ÷ gross revenue) | Days on market |
|---|---|---|---|---|---|
| Duplex (2 units) | 137 | $375,000 | $187,500 | 15x | 7 |
| Triplex (3 units) | 78 | $503,000 | $167,667 | 13.8x | 10.5 |
| Fourplex (4 units) | 37 | $670,000 | $167,500 | 15.2x | 10 |
| 5 units and more | 31 | $900,000 | $146,000 | 14.7x | 46 |

In Trois-Rivières, the triplex costs 10.6% less per door than the duplex: $167,667 versus $187,500. That is the door discount: every additional unit in the same building costs less per unit, because the land, the roof and the structure are shared. The owner-occupant, on the other hand, often pays full price for a duplex door, because they are buying a home first.
Across the 20 cities, the median price per door goes from $235,625 for a duplex to $201,250 for a triplex, $182,562 for a fourplex and $178,542 for a building of 5 units and more. Selling time stretches with size: 10.5 days for a duplex against 38.2 days for 5 units and more, because the pool of buyers able to finance the building shrinks.

In Trois-Rivières, the most expensive door belongs to buildings from 2000 onward ($233,563), the cheapest to buildings from 1959 and earlier ($162,500). The GRM follows: 17.9x versus 13.9x. A recent building costs more per dollar of rent, in exchange for lighter maintenance and units that are easier to rent.
Across the 20 cities, a door in a building from 1959 and earlier costs $200,625 at the median, one in a building from 2000 onward $302,500. The GRM rises as the building gets newer: 14.9x for the old stock, 17.9x for the recent one. New costs more per dollar of rent; old pays back faster but calls for a tight inspection: roof, foundations, plumbing, electrical, and the leases in place.
Around Trois-Rivières: Sorel-Tracy $164,250 per door, GRM 15.1x; Rouyn-Noranda $163,250 per door, GRM 12.5x; Rimouski $160,000 per door, GRM 13x; Lévis $195,000 per door, GRM 14.7x.

Income property sales that moved to "sold" status on Centris (Matrix) between September 16, 2025 and September 16, 2026, up to 300 sales per city, read in Centris number order. For each listing: sold price, number of residential units, declared annual potential gross revenue, days on market and year built. The price per door is the sold price divided by the residential units; the GRM is the sold price divided by the potential gross revenue; each category publishes the median of the listings, never an average. Mixed-use buildings are counted on their residential units only.

$460,000 at the median on 284 sales over the last 12 months, for a median building of 3 units, or $173,417 per door. A duplex and a 5-unit building do not carry the same price: the table by building type gives the detail.
The median is 14.6x. Below it, the building costs less per dollar of rent than half of the recent sales; above it, more. The GRM is calculated on actual rents, never on an advertised potential.
Yes: in Trois-Rivières, a triplex door is worth $167,667 against $187,500 for a duplex. Across the 20 cities, the median goes from $235,625 for a duplex to $178,542 for 5 units and more. The land and the structure are shared between more units, and the pool of buyers shrinks.
