Saint-Lambert, Longueuil - October 2026 Real Estate Report
Saint-Lambert Real Estate Right Now: Steady Prices, But Your Assessment Is Probably Wrong
The Vibe on the Ground
If you've been watching the "For Sale" signs in Saint-Lambert, here's what's actually happening. The market isn't crashing and it isn't exploding. It's holding its ground - which, in this rate environment, is actually a decent story.
Houses: Solid Prices, Quiet Sales Volume
Houses in Saint-Lambert are sitting at an average sale price of $1,200,000, with price per square foot coming in at $804. Sales volume is thin right now - only 1 house traded hands - so we're not reading too much into month-over-month swings. What we can say is that the HonestDoor predicted market value sits at $1,010,666, ticking up slightly from the 3-month moving average of $1,009,703. Small move, but it's moving in the right direction.
- Average sale price: $1,200,000
- Price per sq ft: $804
- HonestDoor predicted value: $1,010,666
- Estimated monthly rent: $4,105
- Rental yield: 4.80%
- Recent value change: +0.16%
For landlords or anyone thinking about renting out a house here, a 4.80% rental yield is a reasonable return - not flashy, but not embarrassing either. Airbnb potential adds roughly $204 a month on top, which covers a utility bill or two.
Condos: Taking a Breather
Condos are a slightly different story. The average sale price is $705,000 at $782 per square foot, but the HonestDoor predicted value is $448,393 - and that number is drifting down slightly from the 3-month moving average of $448,567. It's a small dip, but it's worth watching. The recent value change of -0.80% puts condos in a softer spot compared to houses right now.
- Average sale price: $705,000
- Price per sq ft: $782
- HonestDoor predicted value: $448,393
- Estimated monthly rent: $2,232
- Rental yield: 3.92%
- Recent value change: -0.80%
A 3.92% rental yield on condos is moderate. It works if you bought a few years ago. If you're buying today at $705,000, run your numbers carefully before assuming the rent covers your costs.
The Neighborhood Leaderboard
Here's the honest part. On the growth leaderboard within Saint-Lambert, both houses and condos rank 1 out of 1 comparable neighborhoods tracked. That means Saint-Lambert is the only entry in its own comparison set right now - so treat that ranking as a data point to watch as more comparables get added, not as a verdict on the neighborhood. What we do know is that nearby Lemoyne (HonestDoor Price $319,286) and Greenfield Park (HonestDoor Price $347,377) are significantly cheaper. Saint-Lambert commands a real premium over its neighbors, and that gap has held.
The Secret Sauce: Why Your HonestDoor Price Matters More Than Your Tax Assessment
Here's the thing about government assessments - they're snapshots from the past. The city evaluates your property on a cycle, and by the time that number lands in your mailbox, the market has already moved. The HonestDoor Price updates in real time using actual sales data, algorithm modeling, and current market signals. For a Saint-Lambert house owner, the difference between a $1,010,666 HonestDoor Price and whatever your last assessment says could be tens of thousands of dollars. That gap matters when you're refinancing, selling, or just trying to figure out if your home insurance coverage still makes sense. Check your HonestDoor Price now - don't wait for the city to catch up.
So What Does This Mean If You're Thinking About Selling This Summer?
Selling a house in Saint-Lambert this summer? The price floor looks firm at the $1.2M range, but volume is low - meaning you need your listing to stand out, not just sit there. Buyers are still in the market, but they're not in a panic. Price it right from day one. Overpricing in a low-volume market means sitting, and sitting kills deals.
For condo sellers, the -0.80% value drift is a signal to move sooner rather than later if you've been on the fence. A soft trend doesn't mean a collapse - it means the window for peak pricing may be narrowing. Get your HonestDoor Price, compare it to your assessment, and have a real conversation with your agent about timing before the summer market peaks and then quiets down in August.
Bottom line - Saint-Lambert is still a premium address on the South Shore. The numbers back that up. But this is not a market where you can set a price and wait. Know your real number, move with intention, and use every data point available to you.
