Best real estate broker in Châteauguay: the proof to verify before signing

Guide · Châteauguay · the western South Shore's entry level

Three hundred and two houses for sale in the cheapest city of the western South Shore: in Châteauguay, the right broker makes the day-one price. Here is how to recognize them.

The best real estate broker in Châteauguay is the one who knows the best-supplied market on the western South Shore: a $525,000 median house in the second quarter of 2026 (flat year over year, +43 % in five years), 36 days, 302 houses active, a seller's market under $790,000 and a buyer's above (11 months of inventory), where the waterfront homes on the Châteauguay River and Lac Saint-Louis sit. The condo ($400,000, 30 days) is rare. You recognize them by their closed sales near the Mercier bridge, in the centre or on the waterfront, their detailed public reviews, their licence verified with the OACIQ and a written pricing method. The Loaa & Manseur team, number 1 team at RE/MAX Platine in 2024 and 2025, 15th RE/MAX team in Canada and in the global top 50 of the official 2026 ranking, with 221 Google reviews at 4.9, is based in Brossard, twenty kilometres away.

What a good broker must know about Châteauguay

Châteauguay (QPAREB sector 39) sold its median house for $525,000 in the second quarter of 2026, flat year over year, +43 % in five years, in 36 days, with 302 active listings, one of the South Shore's largest stocks. The market belongs to the seller under $790,000 (2.5 to 5.8 months of inventory) and to the buyer above (11 months). It is the western South Shore's entry level, with the Mercier bridge to LaSalle and southwestern Montreal: the island's first-time buyers look there, and the 1960s to 1980s bungalows priced at their street's level go in a month; the large waterfront homes wait. A broker who applies the South Shore median ($648,500) to Châteauguay overprices by $120,000.

The seven criteria to judge a broker

1. Recent closed sales in your sector, with addresses and days on market, not a provincial volume.
2. Public, dated, detailed reviews: the score alone says nothing; the content of the reviews says everything.
3. A valid licence in the OACIQ register, and no disciplinary decision.
4. A written pricing method: on which comparable sales, at what date, with what adjustment.
5. A marketing plan you can read before signing: photos, video, distribution, viewing follow-up.
6. A team behind the broker: who answers when they are at a viewing, who coordinates the notary, the inspection, the financing.
7. A measured response time: in a 36-day market, a broker who calls back the next day loses offers.

What we do differently in Châteauguay

The price is set on the closed sales of your Châteauguay street in the last 60 days, never on the South Shore median. Every listing gets its dedicated page in English and French, with professional photos and video, because the buyer often comes from LaSalle, Lachine or Verdun via the Mercier bridge and searches in both languages. And a team answers seven days a week. Our guide living in Châteauguay shows the level of detail we put into each sector.
