The past twelve months in Sainte-Thérèse, month by month

Single-family category, municipality of Sainte-Thérèse, 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 August 2026 (6 days), the slowest December 2025 (38 days); median of the twelve months, 12 days. September (11 days) is below the twelve-month median.
• Inventory: 20 active houses at the low (December 2025), 37 at the peak (June 2026). September, at 32, sits between the two.
• New listings: 182 houses put up for sale from October 2025 to August 2026 (eleven full months), the busiest month being April 2026 (22) and the quietest December 2025 (11). August (16) is below June (20); September (9) covers only the first 16 days of the month.
• Price: houses sold at 98% of asking in September, as in June; over the twelve months, 2 of 12 months closed above asking (ratio of 100% or more), the highest in November 2025 (106%). The median price of a house in Sainte-Thérèse is $650,000 in 2026 to date (104 sales from January to September) against $572,500 in 2025 (150 sales), +13.5%.
• 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 seller's market

Rule: under 4 months of inventory = seller's market, 4 to 6 months = balanced market, over 6 months = buyer's market. Calculation in Sainte-Thérèse: 32 active houses in September ÷ (104 sales in 2026 ÷ 9 months = 11.6 sales a month) = 2.8 months. Verdict: a seller's 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. Sainte-Thérèse ranks 5th of 50, from the tightest market to the slowest (median of cities: 3.9 months).

What it changes for selling in Sainte-Thérèse

The market still belongs to the seller in Sainte-Thérèse: 11 days to sell and 2.8 months of inventory. Days on market have shortened since June and buyers are there: a well-prepared seller can aim at the past thirty days' comparables with no room for negotiation, and expect several showings in the first week. The 98% ratio says, however, that bidding wars are no longer the rule: the asking price is the ceiling.

What it changes for buying in Sainte-Thérèse

To buy in Sainte-Thérèse, inventory is still short (32 active houses for about 11.6 sales a month): get financing in place before visiting, and make a complete offer as soon as the right house comes out, because it goes in 11 days in median. Negotiating below asking remains difficult while days on market are this short.
