Listed at $1,518,000, this home is tracking about 21% above a wider set of listings, though close matches were thin, so treat this as a rough read until I run a precise CMA. The number above is my independent estimate of value, not the asking price.
There are only a few closely comparable homes right here, so this is a broad read from wider listings in the area. Ask me for a precise CMA before relying on it.
Based on 14 similar homes nearby, adjusted for size, beds, and baths.Median of 14 comparable active listings, adjusted for size, beds, and baths. The city (MPAC) assessment points to about $1.42M, a bit higher.
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 $1.36M
- Bedrooms +$30K
- Bathrooms +$15K
- Adjusts to $1.40M
That comparable adjusts to $1.40M; the $1.26M estimate above is the median of all 14 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 Bill Hogarth SS, 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. Ninth Line / Donald Cousens Pkwy is about a 2-minute walk away.
Total price vs nearby homes. Fair value about $1.26M, median of 14 comparables.

Rates and programs change often. We will connect you with a trusted mortgage professional and build a plan that fits your budget and goals.
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.
