Marlborough, Ottawa - September 2026 Real Estate Report

Marlborough, Ottawa: Your Neighbours Are Watching Their Home Values Climb

The Vibe Right Now

If you live in Marlborough and you haven't checked your property value lately, you're probably leaving money on the table. This is a neighbourhood that's quietly putting up strong numbers - and the data backs it up.

Let's break it down by property type, because houses and condos are telling two very different stories right now.

Houses: Steady and Climbing

For those of us in detached homes, the market is moving in the right direction. The average HonestDoor Price for a house in Marlborough sits at $874,265 - up 4.64% from the previous period. That's not a fluke. The predicted market value is $835,472, and it's ticking upward past the 3-month moving average of $833,718. Small gap, but the direction matters: up.

On the neighbourhood leaderboard, Marlborough houses rank 12 out of 98 comparable Ottawa neighbourhoods for growth. Top 15 in the city. That's a real number worth talking about at the fence.

• Average HonestDoor Price: $874,265
• Recent price change: up 4.64%
• Predicted market value: $835,472
• 3-month moving average: $833,718
• Estimated monthly rent: $3,739
• Rental yield: 4.98%
• Airbnb estimate: $192 per night
• Growth rank: 12 out of 98 Ottawa neighbourhoods

Compare that to nearby Richmond at $828,869 and North Gower - Kars at $858,640 - Marlborough houses are priced above both. Munster - Ashton edges us out at $928,405, but we're holding our own in a strong peer group.

Condos: The Wildcard - and It's a Big One

Here's where things get interesting. Condo values in Marlborough are ranked number 1 out of 103 Ottawa neighbourhoods for growth. First place. That's not a typo.

The predicted condo market value is $1,202,750 - a significant jump from the 3-month moving average of $866,754. The average HonestDoor Price is $1,139,662. Yes, that figure is down 5.25% from the previous period, but the predicted value is surging well past recent averages. This is a market in motion.

• Average HonestDoor Price: $1,139,662
• Recent price change: down 5.25%
• Predicted market value: $1,202,750
• 3-month moving average: $866,754
• Estimated monthly rent: $4,718
• Rental yield: 2.58%
• Airbnb estimate: $228 per night
• Airbnb rank in Ottawa: 7th
• Growth rank: 1 out of 103 Ottawa neighbourhoods

For context, nearby North Gower - Kars condos are sitting at $1,298,889 - slightly above us. But Marlborough is the one with the number-one growth rank. That gap could close fast.

The Secret Sauce: Your HonestDoor Price vs. Your Tax Assessment

Here's the honest truth about city assessments: they're snapshots from the past. Ottawa's property assessments don't update in real time. They can lag by years. So if you're using your last tax notice to guess what your home is worth today, you're almost certainly working with stale information.

The HonestDoor Price is different. It pulls from current market data and updates regularly - giving you a real-world check on what your property is actually worth right now, not what it was worth two or three years ago. In a neighbourhood like Marlborough, where house values are up over 4.6% and condos are ranked first in Ottawa for growth, that gap between your assessment and your real value could be significant. We're talking tens of thousands of dollars in some cases.

Check your HonestDoor Price before you make any decisions. It takes two minutes and it could change how you think about your next move.

The So What - Should You Sell This Summer?

If you've been on the fence, here's the straight answer: Marlborough is performing. Houses are in the top 15 in Ottawa for growth. Condos are number one. Values are trending upward heading into summer, which is historically the busiest selling season.

A few things worth keeping in mind before you call an agent:

• Your HonestDoor Price gives you a current baseline - use it as your starting point, not your city assessment.
• Rental demand is real here. At $3,739 per month estimated for houses, holding and renting is a legitimate option if selling doesn't feel right yet.
• Condo owners especially should pay attention. A number-one growth rank means buyer interest is high. That's leverage at the negotiating table.
• Airbnb potential is strong too - Marlborough ranks 7th in Ottawa for condo short-term rental income. That's worth knowing if you're weighing your options.

Bottom line: if you own in Marlborough right now, the numbers are working in your favour. The question is just whether you want to act on that - or wait and see how the fall market shapes up. Either way, know your real number first.
