Valuation · Châteauguay · QPAREB Q2 2026 figures
Your Châteauguay house is worth its street's price, not the municipal roll's, and with 43 % more supply the right price counts twice. Here are the 2026 benchmarks, what adds or takes away value, and how to get a free range within 24 hours.
A house in Châteauguay is worth what the houses on its street sold for in the last 60 to 90 days, not what the municipal roll or the median says: $525,000 for the single-family home in the second quarter of 2026 (flat year over year, +43 % in five years), in 36 days, with 302 houses active (+43 %, the South Shore's sharpest rise in supply), a seller's market up to $790,000 and a buyer's market above (11.0 months of inventory). Behind that median, Châteauguay sells street by street: the waterfront on the river and Lac Saint-Louis above, the recent cottages of the northwest at or above the median, the 1960s to 1980s bungalows of the centre and south below. For a written range on your street's closed sales, it is free and within 24 hours.
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 active listings (+43 %), a seller's market up to $790,000 and a buyer's market above. The condo, $400,000 (+11 %) in 30 days with 47 listings, goes fast. The whole South Shore: $648,500 in 30 days; in August, $655,000 in 37 days with 28 % more listings. These figures place the market; they do not say what your house is worth, because in Châteauguay a waterfront home near Île Saint-Bernard and a 1970 bungalow in the centre have nothing in common. 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 the certificate of location that documents the shoreline make the gap, and above $790,000 the buyer negotiates. 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. The centre and the south, around boulevard Saint-Jean-Baptiste and old Châteauguay, sell the 1960s to 1980s bungalows below the median, where the roof, the windows and the kitchen make the gap. Your municipality's three-year roll is set at a reference date eighteen months before it is filed; it smooths an entire sector and sees neither the condition nor the renovations of your house.

No. Your municipality's three-year roll is set at a reference date eighteen months before it is filed; it smooths an entire sector and sees neither the condition nor the renovations of your house. Your market value is the price of your street's closed sales today, above or below the roll depending on the street.
The Châteauguay median is flat year over year in the second quarter of 2026 after +43 % in five years; but with 302 houses active, your street may have done better (the river, the recent sectors) or worse (original-condition bungalows, the high end above $790,000). Only your street's closed sales can tell.
No. The written range with the comparables is free and without obligation; you have nothing to sign to get it. You decide afterwards, with the number in hand.
No. The chartered appraiser is required in certain cases (lender, estate, divorce, dispute); to set a sale price, the broker's comparative analysis on the street's closed sales is the reference, and it is free.
