Westmount, Montreal - September 2026 Real Estate Report

Westmount Real Estate Update: The Numbers Your Tax Bill Isn't Telling You

The Vibe Right Now

If you've been watching the "For Sale" signs on Westmount's tree-lined streets, here's what's actually happening. The market is taking a breather. House values are sitting at a predicted $2,872,094 - and that number is sliding. It's down from the 3-month moving average of $2,898,898, and the recent change clocks in at -2.15%. That's not a crash, but it's a signal worth paying attention to.

For those of us who own here, the honest read is this: we're in a softer patch. Westmount ranks 25 out of 27 comparable neighbourhoods in Montreal for growth right now. That puts us near the bottom of the leaderboard - not a comfortable spot, but knowing it is better than guessing.

The Numbers, Straight Up

• Predicted House Value: $2,872,094
• 3-Month Moving Average: $2,898,898 (values are trending down)
• Recent Value Change: -2.15%
• Average HonestDoor Price (houses): $6,105,300 (up 0.48% from the previous period)
• Estimated Monthly Rent: $8,682
• Rental Yield: 3.42% - moderate, but real income
• Airbnb Potential: $431 per month
• Growth Rank: 25 out of 27 in Montreal

The Secret Sauce - Why Your HonestDoor Price Matters More Than Your Tax Assessment

Here's the thing most Westmount homeowners don't realize. Your city tax assessment is a snapshot frozen in time. It doesn't know what happened in the market last month, last quarter, or even last year. It's a static number built on old data.

The HonestDoor Price is the real-world check. It updates in real time, pulling in actual market signals. Right now, the average HonestDoor Price for a house in Westmount is $6,105,300 - and it's up 0.48% from the previous period. That gap between what the city thinks your home is worth and what the market actually says it's worth? That's the number that matters when you're making a financial decision. Don't wait for the next assessment cycle to find out where you stand.

The "So What?" - Thinking About Selling This Summer?

If selling is on your mind, the data is giving you a clear message: don't wait for the market to come back to you. Values are drifting down, not up. Every month you wait, the 3-month average is working against your asking price.

The rental story does offer some cushion. At $8,682 per month in estimated rent and a 3.42% yield, holding the property as a rental is a real option - not just a fallback. And with Westmount ranking number 1 in all of Montreal for Airbnb potential, short-term rental income is a genuine lever if you want flexibility before committing to a sale.

But if selling is the goal, summer 2025 is a window worth taking seriously. Price it sharp, know your HonestDoor Price before you list, and don't let a stale tax assessment anchor your expectations in the wrong direction.

How Westmount Stacks Up Nearby

For context, Le Sud Ouest is sitting at an average HonestDoor Price of $900,220 with estimated rent of $3,848. Westmount is in a completely different price tier. That premium is real - but it also means our pool of buyers is smaller, and pricing precision matters more here than almost anywhere else in the city.
