Market context: duplex in Lachine
The duplex market in Lachine during July 2025 recorded nine documented sales, with a median price of $587,300 and an average price of $621,644. This median establishes Lachine significantly below the broader Montréal duplex market, which recorded a median of $810,000 over the trailing twelve months across 458 transactions. The neighbourhood's median price sits 27.5 percent below the city-wide figure, positioning Lachine as a more affordable market segment within Montréal's duplex landscape for buyers seeking properties in this category. The pace of sales activity is reflected in an average of seventy-three days on the market, indicating a moderate selling timeline that neither suggests rapid absorption nor extended inventory periods. This timeframe reflects a measured market where properties typically require between two and three months to move from listing to close, a rhythm that suggests neither exceptional urgency nor notable stagnation in buyer demand. Among the nine documented sales, the sale-to-asking price ratio averaged 0.968, meaning that homes sold at approximately 96.8 percent of their asking prices on average across these transactions. This figure, grounded in the nine recorded sales from July 2025, indicates that buyers held slight leverage in negotiations, with properties generally selling modestly below initial asking price rather than commanding premiums above list. The building profile reveals that all nine documented sales involved properties built before 1980, with no transactions recorded for duplexes constructed between 1980 and 2010, and none from the post-2010 period. This composition reflects Lachine's housing stock characteristics, where the duplex inventory consists entirely of older constructions, a profile that carries implications for buyers regarding maintenance expectations, building systems, and potential renovation requirements inherent to pre-1980 housing stock. A significant due-diligence consideration emerges from the transaction data: approximately one-third of the sales, specifically 33 percent of the nine documented transactions, were concluded without legal warranty of quality. This occurrence reflects a standard aspect of real estate transactions where buyers proceed with standard inspections and conventional due-diligence checks rather than relying on seller-provided warranties, a practice that remains routine in residential real estate. For buyers entering the Lachine duplex market, the neighbourhood's position at nearly 28 percent below Montréal's median duplex price represents meaningful value, particularly when accounting for the older construction profile requiring careful inspection. For sellers, the moderate seventy-three-day selling period and sub-asking price ratios suggest patience and realistic pricing expectations in a market where competition requires strategic positioning.
