Quartier Cote-Saint-Louis, Blainville: Here's What Your Home Is Actually Worth Right Now

If you own a place in Quartier Cote-Saint-Louis and you haven't checked your HonestDoor Price lately, this is your nudge. The market here is moving - not dramatically, but enough that the number on your last tax assessment is almost certainly out of date. Here's the real picture.

The Vibe: Houses vs. Condos

We're seeing two different stories play out on our streets right now, depending on what you own.

Houses: The average HonestDoor Price sits at $962,764, down a very modest 0.31% from last period. That's not a warning sign - it's a market taking a breather. The predicted market value is actually nudging up to $965,304, which is above the 3-month moving average of $963,914. So the short-term trend is quietly pointing in the right direction. Sales volume is thin - only 1 house sold recently - so we're not dealing with a flood of listings dragging prices down. Price per square foot is around $478, and if you're renting your place out, you're looking at roughly $3,985 per month in estimated rent. That works out to a rental yield of 4.89%, which is a solid, moderate return.

Condos: This is where things get a bit more interesting for us. The average HonestDoor Price for condos is $674,435, up 0.05% from last period. The predicted market value of $674,129 is running well above the 3-month moving average of $667,270 - that gap tells us momentum is building. Condo values have shifted 2.15% recently, which is the stronger move of the two property types right now. Estimated rent comes in at $3,169 per month, with a rental yield of 3.51%.

• House HonestDoor Price: $962,764 (down 0.31%)
• House predicted market value: $965,304
• House price per square foot: $478
• House rental estimate: $3,985/month - yield 4.89%
• House Airbnb estimate: $197/night - Blainville rank: 2nd
• Condo HonestDoor Price: $674,435 (up 0.05%)
• Condo predicted market value: $674,129
• Condo rental estimate: $3,169/month - yield 3.51%
• Condo Airbnb estimate: $158/night - Blainville rank: 1st

On the neighbourhood leaderboard, both houses and condos rank 7 out of 10 for growth among comparable Blainville neighbourhoods. That puts us in the below-average tier for growth right now. Houses also rank 4 out of 5 for price, meaning we sit on the higher end of the price scale locally. Nearby Quartier Fontainebleau is running higher on house prices at $1,126,417, but for condos, we're actually ahead of every comparable neighbourhood listed - Fontainebleau, Plan-Bouchard, and Lorraine all come in cheaper.

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

Here's the thing about your city assessment - it's a snapshot from the past. It gets updated on a fixed schedule, and by the time it lands in your mailbox, the market has already moved on. The HonestDoor Price is a real-time estimate that reflects what buyers are actually paying right now, not what they were paying a year or two ago.

For a house in Quartier Cote-Saint-Louis, the gap between the assessed value and the HonestDoor Price of $962,764 could be significant. If you're making any financial decision - refinancing, selling, even just figuring out your net worth - you want the current number, not the stale one. Think of the HonestDoor Price as the real-world check that keeps you from leaving money on the table or making a move based on outdated information.

For condo owners especially, with values up 2.15% recently and the predicted value climbing above the 3-month average, checking your HonestDoor Price today gives you a clearer read on where you actually stand heading into summer.

The So What: Thinking About Selling This Summer?

Selling in Quartier Cote-Saint-Louis this summer is a reasonable play, but go in with clear eyes. Here's what the data is telling us.

On the house side, prices are essentially flat with a slight dip of 0.31%. Volume is low. That means less competition from other sellers, but also fewer active buyers in the pool. If your house is priced right and shows well, you're not fighting a crowded market. The Airbnb rank of 2nd in Blainville at $197 per night is also a talking point for buyers who want income potential - use it.

On the condo side, the story is better. Values are trending up, the predicted price is above the moving average, and Quartier Cote-Saint-Louis condos are priced higher than every nearby neighbourhood we have data on. That's a positioning advantage. If you're a condo owner thinking about timing, the current momentum is working in your favour.

Either way, the move right now is simple - check your HonestDoor Price before you call an agent, set a list price, or make any assumptions based on what your neighbour sold for six months ago. The market in Cote-Saint-Louis is not standing still, and neither should your information.
