Market context: duplex in Le Sud-Ouest
The duplex market in Le Sud-Ouest recorded eight sales in July 2026, establishing a median transaction price of $767,500 and an average price of $801,750. This neighbourhood continues to position itself as an affordable alternative within Montréal's duplex market, trading at 10.3 percent below the city-wide median of $856,000 recorded across 997 documented sales over the trailing twelve months. This meaningful price differential reflects Le Sud-Ouest's sustained appeal for buyers seeking duplex ownership at a lower entry point compared to the broader Montréal market. The average days on market for these eight transactions stood at 62 days, indicating a moderate sales pace that suggests neither urgent liquidation nor extended stagnation. This timeframe reflects a balanced market dynamic where properties spent roughly two months from listing to sale, a pace typical of neighbourhoods with steady underlying demand and reasonably priced inventory. Among the documented sales, the average sale-to-asking price ratio reached 0.966, meaning that properties in this sample sold at approximately 96.6 percent of their asking prices on average. This figure, derived from the eight recorded transactions, reveals that sellers maintained modest negotiating leverage during this period, with most transactions concluding slightly below list price rather than commanding premiums. The ratio suggests a buyer-leaning market where price discovery favoured purchasers willing to negotiate. The neighbourhood's duplex stock presents a notably homogeneous building profile: 100 percent of the eight sampled sales involved structures built before 1980, while no transactions involved properties constructed between 1980 and 2010, or after 2010. This composition reflects Le Sud-Ouest's established character as a mature residential neighbourhood with older housing stock requiring the due diligence typical of pre-1980 construction, including thorough inspection protocols and standard structural and systems verification. Half of the eight transactions concluded without a legal warranty of quality, a finding that underscores the importance of standard due-diligence practices for buyers. Engaging professional home inspections, verifying building systems, and conducting title searches represent routine protective measures that purchasers should pursue regardless of warranty structure. For buyers, Le Sud-Ouest's duplex market offers established neighbourhood character and below-city pricing at a measured sales pace. For sellers, the modest gap between asking and selling prices suggests that realistic initial pricing aligned with market conditions will facilitate more efficient transactions.
