Listing history
- Jun 4, 2026Listed$9,800
Price and status history from the listing board. Deemed reliable but not guaranteed.
Listed at $3,338,000, this home is about 34% above what comparable homes suggest. The number above is my independent estimate of value, not the asking price.
Priced above comparable homes overall, but the price per square foot ($785/sqft) is below the area, so you are paying for extra space rather than a premium.
There were not many closely comparable homes right in Thornhill, so I widened the search to the surrounding area.
Based on 7 similar homes nearby, adjusted for size, beds, and baths.Median of 7 comparable active listings, adjusted for size, beds, and baths. The city (MPAC) assessment points to about $3.70M, higher than the comparables and worth a second look. The comparable range is wide here, so treat this as a rough read until I run a full CMA.
How I got there
Here is the exact math behind the estimate. I start from the closest comparable listing and adjust for the real differences (size, beds, baths) to land on a like-for-like value for this home.
- Closest comparable, listed at $2.45M
- Bedrooms +$30K
- Bathrooms +$15K
- Adjusts to $2.50M
That comparable adjusts to $2.50M; the $2.50M estimate above is the median of all 7 comparables, which is steadier than any single home.This uses comparable active listings, not sold prices. Lot, condition, and finishes are my in-person call, and I can run a full CMA with recent solds.
Its public catchment (Thornhill SS) tests around the provincial average, a steady, family-friendly draw. The full EQAO breakdown is below.
On location, it is moderately walkable, so some daily errands are within reach and for the rest you will likely drive. Henderson Av / Elgin St is about a 2-minute walk away.
Total price vs nearby homes. Fair value about $2.50M, median of 7 comparables.
What the listing highlightsThese are claims from the listing. The only way to know for sure is to see it in person, and I am happy to book you a private showing.
- Finished basement: added living space, worth checking ceiling height and that the work was permitted.
- Pool: lifestyle appeal, but adds maintenance, insurance, and resale is mixed.
- Tall ceilings: they transform how a home feels, worth confirming the actual heights room to room.
- Primary suite: a key comfort and resale feature.
- Open-concept layout: modern, sought-after flow.

Estimates only, not a mortgage quote or pre-approval.

Investor snapshot
Thinking of this home as an investment? We will pull real comparable rents and run the full numbers with you.
Talk about the numbersEstimates only. Rent is modelled on above-grade size and local norms, so a finished basement or second suite (a separate entrance often means one) can push real rent well above this. Taxes, fees, and vacancy vary by property, and cap rate is before financing. A starting point, not a final number, let us run the real ones with you.
