Market context: duplex in Saint-Laurent
The duplex market in Saint-Laurent recorded nine sales in June 2025, establishing a median price of $900,000 and an average price of $898,056. This positions the neighbourhood notably above the broader Montréal duplex market, where the median over the trailing twelve months across 353 documented transactions stood at $815,000. Saint-Laurent's median thus sits 10.4 percent higher than the city as a whole, reflecting the neighbourhood's particular appeal and positioning within the metropolitan real estate landscape. With a modest transaction volume in the month, Saint-Laurent represents a selective segment of the larger duplex market, warranting careful observation of market dynamics given the small sample size. Properties in Saint-Laurent spent an average of eighty-nine days on the market before sale, a timeframe that suggests a measured pace of transaction closure. This duration indicates neither a particularly fast nor sluggish market; rather, it reflects conditions in which buyers and sellers negotiate with neither party exerting overwhelming pressure on the other. The timeframe offers sellers a reasonable window within which to attract qualified purchasers while allowing buyers sufficient time to make informed decisions. The building stock in Saint-Laurent tells a story firmly rooted in older construction. All nine recorded sales involved duplexes built before 1980, with no transactions recorded for properties constructed between 1980 and 2010 or after 2010. This composition means that buyers in Saint-Laurent are engaging almost exclusively with older, well-established residential stock that reflects decades of neighbourhood settlement patterns and architectural character. When evaluating older duplexes, prospective buyers routinely conduct inspections and standard due-diligence checks on property condition, systems, and compliance matters. In Saint-Laurent's June market, fifty-six percent of the nine documented sales concluded without a legal warranty of quality, a proportion that underscores the importance of such buyer-initiated diligence work before purchase. This arrangement places added responsibility on the purchaser to verify the property's condition and systems through professional inspection and municipal records review, standard practice in real estate transactions across Montréal. For a buyer, careful inspection and due diligence become essential tools when pursuing older properties where legal warranty protection may not be contractually offered. For a seller, presenting a well-documented property history and inviting pre-purchase inspections can strengthen buyer confidence in transactions involving older duplexes.
