If you own a home in Marlborough and the last number you checked was your city tax assessment, you are probably sitting on a very outdated picture of what your property is actually worth. Here is what the real-world data looks like right now.
Let us start with houses, because that is where the story gets interesting for most of us in Marlborough.
That growth rank is the number to pay attention to. Out of 99 comparable Ottawa neighbourhoods, Marlborough houses sit at number 10 on the leaderboard. That puts us in the top 10% for growth. Compare that to nearby Richmond at $824,479 or North Gower - Kars at $847,906, and Marlborough houses are holding a clear price advantage over both.
Now for condos - and we will be straight with you here, the picture is more mixed.
A rank of 79 out of 104 puts Marlborough condos in below-average territory for growth right now. The condo segment is taking a breather - possibly a longer one. If you own a condo here, that does not mean panic, but it does mean timing matters more than it does for house owners.
Here is the thing about city assessments in Ottawa - they are snapshots from the past. They get updated on a cycle, which means the number on your property tax bill could be reflecting a market that existed a year or two ago, not the one we are living in today.
The HonestDoor Price is updated in real time using actual market activity. Right now, it is showing Marlborough house values at $870,331 on average, with a predicted value climbing to $874,265 - sitting above the 3-month moving average of $844,356. That gap between what the city thinks your home is worth and what a buyer would actually pay today? That is money left on the table if you do not know about it.
Check your HonestDoor Price now. Do not wait for the city to catch up to your neighbourhood.
If you own a house in Marlborough and you have been on the fence about listing this summer, the data is nudging you toward action. A top-10 growth rank in Ottawa, a predicted value above the recent moving average, and a rental yield near 5% all signal that buyer demand for houses here is real. You are not selling into a soft market - you are selling from a position of strength relative to most of Ottawa.
For condo owners, the honest advice is this - move with intention. The 5.78% price dip and a below-average growth rank mean the window for peak pricing may be narrowing. If selling is on your radar, sooner is likely better than later while predicted values are still holding above $1.1 million.
Either way, the first step is the same. Pull your HonestDoor Price, compare it to what the city has on file, and you will immediately see the real gap between yesterday's assessment and today's market. That number is your starting point for every conversation with a realtor this summer.
