Listed at $2,388,000, this home is about 26% 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 ($735/sqft) is in line with the area, so you are paying for extra space rather than a premium.
There were not many closely comparable homes right in Thornlea, so I widened the search to the surrounding area.
Based on 20 similar homes nearby, adjusted for size, beds, and baths.Median of 20 comparable active listings, adjusted for size, beds, and baths. The city (MPAC) assessment points to about $2.39M, higher than the comparables and worth a second look.
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 $1.50M
- Bathrooms +$15K
- Adjusts to $1.51M
That comparable adjusts to $1.51M; the $1.89M estimate above is the median of all 20 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.
On schools, this address is zoned for Bayview Glen PS, one of the higher-rated public schools in the area. A strong catchment tends to hold value and widen your resale pool, especially with family buyers.
On location, it is moderately walkable, so some daily errands are within reach and for the rest you will likely drive. Leslie St / Tanglewood Trl is about a 2-minute walk away.
Total price vs nearby homes. Fair value about $1.89M, median of 20 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.
- Ravine lot: privacy and premium value, but confirm the buildable area and any conservation limits.
- Pool: lifestyle appeal, but adds maintenance, insurance, and resale is mixed.
- Premium lot / gardens: lot size and privacy hold value and cannot be changed, verify frontage, depth, and any easements.
- Primary suite: a key comfort and resale feature.

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.
