Selling · Châteauguay · QPAREB Q2 2026 figures
Châteauguay has 43 % more houses for sale than a year ago: the buyer compares, and only the house priced at its street's level goes in 36 days. Here are the 2026 figures, the pricing method and the calendar.
Selling a house in Châteauguay in 2026 means selling in the South Shore market where supply rose the most: a $525,000 median for the single-family home in the second quarter (flat year over year, +43 % in five years), 36 days on market, 302 houses active (+43 %), a seller's market up to $790,000 (2.5 months of inventory between $260,000 and $390,000, 3.0 months between $390,000 and $660,000) and a buyer's market above (11.0 months). The price is set street by street: the waterfront on the Châteauguay river and Lac Saint-Louis and the recent homes of the northwest above the median, the 1960s to 1980s bungalows of the centre and south below it. A condo ($400,000, +11 %, 30 days, 47 listings) goes fast. The method: the closed sales of the street, a fair price from day one, a full launch on Thursday, offers on Monday.
Châteauguay (QPAREB sector 39) sold its median house for $525,000 in the second quarter of 2026, flat year over year and +43 % in five years, in 36 days (36 over twelve months), with 302 houses active, up 43 %, the South Shore's sharpest rise; the condo sold for $400,000 (+11 %) in 30 days with 47 listings. The market is the seller's up to $790,000 and the buyer's above (11.0 months of inventory): the large waterfront and recent homes above that threshold negotiate. Châteauguay remains the cheapest city in the western South Shore, ahead of the Southwest ($620,000) and Candiac-La Prairie ($820,000). The whole South Shore: $648,500 in 30 days in the second quarter; $655,000 in 37 days in August with 3,703 active listings (+28 %). The monthly picture is on the South Shore's August 2026 report.

The waterfront on the Châteauguay river and Lac Saint-Louis, near Île Saint-Bernard and its wildlife refuge, sells above the median on few comparables: the view, the lot and a certificate of location that documents the shoreline make the gap. The 1990s to 2020 sectors of the northwest, toward Highway 30 and Mercier, sell the family cottages at or above the median, where the garage and the finished basement make the gap and the buyer compares with new construction. The centre and the south, around boulevard Saint-Jean-Baptiste and old Châteauguay, sell the 1960s to 1980s bungalows below the median, where condition (roof, windows, kitchen) makes the gap; it is the market of first-time buyers crossing the Mercier bridge. Our page on home prices by city on the South Shore places Châteauguay against its neighbours.
The sector median tells you where the market sits, not what your house is worth. Our valuation starts from the closed sales of the last 60 to 90 days on your street and the streets next to it (same type, same era, same lot), adjusts for what differs (finished basement, garage, pool, roof, windows, kitchen), then looks at what is for sale right now at the same price: that is your real competition. Pricing 3 % too high in a 30-day market costs you the first weekend, when viewings concentrate; pricing right produces multiple offers. We show you the comparables, not a promise.

36 days in median in the second quarter of 2026, 30 days for a condo. With 302 houses active, a house priced at its street's level receives its offers in the first two weeks; above $790,000, the buyer leads and the delay is counted in months.
Spring (March to June) concentrates buyers, but September and October are the second peak with thinner supply; winter sells slower but with less competition. With 43 % more supply, preparation and the day-one price matter more than the season.
Small visible work (paint, floors, refreshed kitchen, landscaping) pays back; big work (roof, windows, basement) rarely pays back 100 % and negotiates better as a price adjustment. For a 1970s bungalow, a documented roof, windows and electrical panel reassure more than a new kitchen.
The broker's compensation, agreed in the brokerage contract and payable at the sale; the certificate of location if outdated ($1,200 to $2,500); the mortgage penalty if you break a term (three months of interest or the interest rate differential); the notary's fees for the discharge. Our free valuation puts numbers on all of it before you decide.
