Listed at $2,280,000, this home is about 4% below comparable homes, worth a close look. The number above is my independent estimate of value, not the asking price.
Below comparable homes on total price, yet the price per square foot ($702/sqft) is above the area, which usually points to a smaller or more efficient layout.
Based on 5 similar homes nearby, adjusted for size, beds, and baths.Median of 5 comparable active listings, adjusted for size, beds, and baths. The city (MPAC) assessment points to about $2.74M, 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 $2.39M
- Bedrooms −$30K
- Adjusts to $2.36M
That comparable adjusts to $2.36M; the $2.38M estimate above is the median of all 5 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 Pierre Elliott Trudeau HS, 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. Rodick Rd / Macrill Rd is about a 9-minute walk away.
Total price vs nearby homes. Fair value about $2.38M, median of 5 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.

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.

Actual rates, taxes, insurance, and closing costs vary by lender and property. Confirm every number with your mortgage professional.
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.
