Quartier Cote-Saint-Louis, Sainte-Thérèse - October 2026 Real Estate Report
Quartier Cote-Saint-Louis, Sainte-Thrse: The Market Is Shifting - Here Is What Your Home Is Actually Worth Right Now
The Vibe on the Ground
If you have been watching the "For Sale" signs in Quartier Cote-Saint-Louis lately, here is the honest picture. The average HonestDoor Price sits at $633,567 - and it has dipped 4.87% from the previous period. That is not a crash. That is the market taking a breather. But it does mean the number on your last tax assessment is probably not the number you should be quoting at a dinner party right now.
One thing worth noting: Quartier Cote-Saint-Louis holds the number 1 Airbnb rank in all of Sainte-Thrse. If you have a spare unit or a basement suite, that is real money on the table - around $152 per night in estimated Airbnb income.
Houses vs. Condos - What Is Actually Happening
Let us break it down by property type, because the two stories here are pretty different.
Houses
- Average sale price: $670,000 - essentially flat month over month
- Price per square foot: $478
- Predicted market value: $962,346
- 3-month moving average: $964,650 - values are easing slightly, down 0.31%
- Estimated rent: $3,974 per month
- Rental yield: 4.90% - that is a solid return for this area
- Neighbourhood leaderboard: Growth ranks 2 out of 10 in Blainville - that puts us near the top of the pack
- Price rank: 4 out of 5 - we are on the more affordable end compared to similar neighbourhoods
One sale closed last month. That is a thin number, which means each transaction carries a lot of weight in how the averages move. Do not read too much into a single data point - but do pay attention to that predicted value of $962,346. That gap between sale price and predicted value is worth a conversation.
Condos
- Predicted market value: $675,538
- 3-month moving average: $670,451 - values are actually ticking up here
- Recent value change: up 0.04%
- Estimated rent: $3,165 per month
- Rental yield: 3.51% - moderate but steady
- Airbnb income potential: around $158 per month
- Neighbourhood leaderboard: Growth ranks 2 out of 10 in Blainville - same strong position as houses
- Compared to nearby Quartier Fontainebleau condos at $637,850 - our condos are priced higher right now
Condos are quietly holding their ground. While houses dip slightly, condo values here are nudging upward. That is not nothing. If you own a condo in Quartier Cote-Saint-Louis, the trend is moving in your favour.
The Secret Sauce - Why Your HonestDoor Price Matters More Than Your Tax Assessment
Here is the thing about your municipal assessment: it is a snapshot from the past. The city looks at sale data from a fixed window and locks in a number that can be 12 to 24 months out of date by the time it lands in your mailbox. A lot can change in that time - and in this market, it has.
The HonestDoor Price is updated in real time using current sales, local trends, and live market signals. Right now, that number is $633,567 for homes in Quartier Cote-Saint-Louis. That is the real-world check. If your assessment is sitting higher than that, you might be paying more in property taxes than you should. If it is lower, you could be leaving money on the table when you sell. Either way, you want to know the real number - not the government's old one.
The So What - Thinking About Selling This Summer?
Summer is historically when buyers come out. Families want to move before school starts. Inventory tightens. That usually works in a seller's favour. But here is the honest take for Quartier Cote-Saint-Louis right now.
The HonestDoor Price has pulled back 4.87%. That means if you were hoping to hit a peak-of-market number, that window may have passed for the moment. Waiting for values to climb back up is a gamble - and nobody can promise you that timeline.
What we can say is this: a growth rank of 2 out of 10 in Blainville means this neighbourhood is still outperforming most of the competition. Buyers looking at the area know that. A well-priced home - priced to the HonestDoor number, not wishful thinking - will move. One that is overpriced will sit, and sitting costs you money every month.
If you are serious about selling this summer, pull your HonestDoor Price today, compare it to your assessment, and have an honest conversation about where the market actually is. That is the move.
