The past twelve months in Saint-Jean-sur-Richelieu, month by month

Single-family category, municipality of Saint-Jean-sur-Richelieu, Centris (Matrix), read September 16, 2026. September 2026: data from September 1 to 16 (month in progress). Days on market = days between listing and accepted offer, median of the month's sales; ratio = sold price ÷ asking price, median.

What the twelve months say

• Days on market: the fastest of the twelve months was February 2026 (8 days), the slowest July 2026 (32 days); median of the twelve months, 18 days. September (21 days) is above the twelve-month median.
• Inventory: 203 active houses at the low (December 2025), 304 at the peak (April 2026). September, at 289, sits between the two.
• New listings: 1,184 houses put up for sale from October 2025 to August 2026 (eleven full months), the busiest month being April 2026 (150) and the quietest December 2025 (48). August (110) is above June (94); September (67) covers only the first 16 days of the month.
• Price: houses sold at 99% of asking in September, as in June; over the twelve months, 1 of 12 months closed above asking (ratio of 100% or more), the highest in March 2026 (100%). The median price of a house in Saint-Jean-sur-Richelieu is $577,000 in 2026 to date (615 sales from January to September) against $555,000 in 2025 (928 sales), +4.0%.
• Across the 50 cities tracked, the September median is 16 days (June: 14 days; October 2025: 12 days); it lengthened since June in 30 cities and doubled in 7. September inventory is higher than June in 39 cities and higher than October 2025 in 44; it is at its twelve-month peak in 24 cities. 26 cities are in a seller's market, 20 in a balanced market, 4 in a buyer's market.

Months of inventory and verdict: a balanced market

Rule: under 4 months of inventory = seller's market, 4 to 6 months = balanced market, over 6 months = buyer's market. Calculation in Saint-Jean-sur-Richelieu: 289 active houses in September ÷ (615 sales in 2026 ÷ 9 months = 68.3 sales a month) = 4.2 months. Verdict: a balanced market. It is an approximation: 2026 sales stop on September 16 and are divided by nine full months, which nudges the result slightly upward; the actual pace of September may differ from the year's average. Saint-Jean-sur-Richelieu ranks 31st of 50, from the tightest market to the slowest (median of cities: 3.9 months).

What it changes for selling in Saint-Jean-sur-Richelieu
