If your neighbour just got their tax assessment and felt a little underwhelmed, you are not alone. The city has Thornhill houses pegged at an average of $1,829,681. The HonestDoor Price says the real number is closer to $1,959,535. That is a $129,854 gap - and that gap matters when you are making decisions about selling, refinancing, or just figuring out where you stand.
We are working with a houses-only market here, and the honest picture is this: things have cooled a little, but Thornhill is still holding its ground better than most people realize.
One home sold last month. That is a thin market, which means pricing it right is everything. When volume is low, one bad listing price can define how buyers see the whole street.
On the leaderboard, Thornhill ranks 4 out of 24 neighbourhoods in Maple Ridge for growth rate. That puts us in the top tier. Price rank sits at 7 out of 18 - above average. We are not the cheapest option in the district, and the numbers say we have earned that position.
Here is the thing about government assessments: they are a snapshot from the past. The city looks at sale data from months ago, runs it through a formula, and mails you a number that is already out of date by the time it hits your mailbox.
The HonestDoor Price is a live, real-world check. Right now it is sitting 7.10% above the average assessed value in Maple Ridge. For a Thornhill homeowner, that is not a small rounding error - that is nearly $130,000 in equity that the tax assessment is not giving you credit for.
Yes, the HonestDoor Price has dipped 2.08% from the previous period. That is worth knowing. But a current, market-calibrated number - even one that has softened slightly - is still a far more honest starting point than a static government figure that does not reflect what buyers are actually paying today.
If you are using your assessment to make any financial decision right now, you are working with the wrong number.
Summer is when buyers are motivated and listings move. Here is what the data is telling us for Thornhill right now.
That last point is important. Buyers who get priced out of Thornhill do not disappear - they move to Spilsbury or Albion. That means your competition is not just other Thornhill listings. It is the entire surrounding area offering a lower entry point.
The move this summer is to price with precision. Not aggressive, not timid. The market is thin, buyers are comparing neighbourhoods side by side, and a well-priced Thornhill home - backed by a current HonestDoor Price rather than a stale assessment - is the one that closes.
Check your HonestDoor Price before you do anything else. It is free, it is current, and right now it is telling a better story about your home than the city is.
