Market context: duplex in Lachine
The duplex market in Lachine during February 2026 reflects a specialized and relatively modest segment within the broader Montréal real estate landscape. Over the period captured in current data, five duplex sales were recorded in the neighbourhood, establishing a median price of $652,000. This median sits notably below the broader Montréal duplex market, which recorded a median of $840,000 across approximately 1,000 sales over the trailing twelve months—placing Lachine duplexes at 22.4 percent below the city-wide median. This significant price differential underscores Lachine's positioning as a more affordable option for duplex buyers compared to other neighbourhoods across Montréal, though the small transaction volume warrants attention to the statistical scope of these observations. The pace of sales activity in Lachine duplexes shows healthy momentum, with an average time on market of 24 days. This relatively swift absorption rate suggests that properties are moving through the sales cycle with reasonable velocity, indicating neither excessive inventory pressure nor a severely constrained supply environment. Such a timeframe reflects a moderately active market where neither buyers nor sellers face pronounced friction in completing transactions. For buyers and sellers alike, this pace implies fair market conditions where properties spend less than a month in active listing before finding a transaction partner. Among the documented sales where asking-price data was available, the average sale-to-asking price ratio stood at 0.992, calculated across four documented transactions. This ratio indicates that, on average, properties in this sample sold slightly below their listed asking prices, suggesting that buyer leverage remained relatively balanced during this period. The figure is marginally below parity, reflecting a market dynamic where negotiations tend to favour purchasers modestly without dramatically favouring either party in a structural sense. The construction profile of Lachine's duplex inventory reveals a neighbourhood composed entirely of older building stock. Across the five sales examined, 100 percent of the duplexes dated from before 1980, with no properties falling within the 1980-2010 or post-2010 construction periods. This uniformity speaks to Lachine's character as a historically developed residential area where duplex buildings represent established infrastructure rather than newer developments. In the course of due diligence, buyers should note that 40 percent of the sales concluded without legal warranty of quality. As with any real estate transaction, prospective purchasers benefit from engaging in standard inspection practices and completing customary verification checks on properties before commitment. For buyers, Lachine offers established duplex properties at prices substantially below city medians, presenting value relative to Montréal's broader market. For sellers, the steady sales pace indicates receptive market conditions with realistic pricing expectations.
