Saint-Constant Real Estate Market 2026: Median Prices and Trends (Roussillon)

A town in the Roussillon RCM on Montreal's South Shore, Saint-Constant posts a median house at $645,000 and a condo at $400,750 in 2026, two segments of remarkable stability. For a look at a direct neighbour, see our analysis of the La Prairie market in 2026. Here is the detailed picture, based on CourtiConnect comparable sales.

Saint-Constant at a glance

Saint-Constant belongs to the Roussillon RCM in Montérégie, next to Delson, Sainte-Catherine and La Prairie. The town has grown steadily since the 1980s: the median construction year among houses sold over the last twelve months is 1993, with a median living area of about 1,123 square feet. The condo stock is far newer, with a median year of 2013, the product of the past decade's developments.

Median prices by property type

CourtiConnect data for the twelve months ending in June 2026, against the previous twelve months:

• Single-family home: $645,000 (172 sales) — flat, against $644,000 a year earlier
• Condo: $400,750 (70 sales) — also flat, against $402,000 a year earlier

Stability that clean across both segments is uncommon. It points to a mature market where supply and demand meet without jolts. The middle half of the house market runs from $599,000 to $730,000; the condo range is far tighter, $380,000 to $420,000, a direct consequence of recent, homogeneous stock.

A balanced market where negotiation still happens

The most telling indicator is not price but the share of sales closing at or above asking: about 39% for houses and 33% for condos. In other words, in most transactions the buyer pays less than the list price. This is not a struggling market: selling times remain short, about 34 days for houses and 29 for condos. It is a market where negotiation is part of the normal process.

The contrast with other South Shore towns is instructive. In Sainte-Julie, about 55% of houses sell at or above asking, at a $725,000 median. Two family suburbs some thirty kilometres apart, two different balances of power: which is why a regional median never replaces the analysis of a specific area.

For the buyer

Saint-Constant offers a rare equation: a median house slightly below the Montreal area figure ($649,000 in June 2026) and a condo about $34,000 below the metropolitan median ($435,000), with a recent condo stock that limits nasty maintenance surprises. With the 5-year fixed down to 4.09% in Montreal on July 23, 2026, a $645,000 house financed with 20% down runs about $2,737 a month in principal and interest.

Since negotiating room is real, it pays to have an analysis of comparable sales in the exact area prepared before submitting an offer, rather than starting from the list price.

For the seller

In a market where two thirds of transactions close below list, the inflated price "to leave room for negotiation" backfires quickly: it stretches time on market, then forces visible reductions that weaken your position. A price anchored on recent comparables draws more qualified buyers in the opening weeks, when interest is highest.

One last useful marker: the $599,000 to $730,000 range for houses shows the market's real spread. Two properties in the same neighbourhood can sit at opposite ends depending on condition, size and lot. It is that relative position, not the median, that sets your price.
