Rooms
Listed at $5,750,000, this home is about 22% below comparable homes, worth a close look. The number above is my independent estimate of value, not the asking price.
Based on 13 similar homes nearby, adjusted for size, beds, and baths.Median of 13 comparable active listings, adjusted for size, beds, and baths. The city (MPAC) assessment points to about $7.67M, a close match.
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 $5.89M
- Bathrooms +$15K
- Adjusts to $5.90M
That comparable adjusts to $5.90M; the $7.35M estimate above is the median of all 13 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 location, it is moderately walkable, so some daily errands are within reach and for the rest you will likely drive. Devon Rd + Morrison Rd is about a 12-minute walk away.
Total price vs nearby homes. Fair value about $7.35M, median of 13 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.

Actual rates, taxes, insurance, and closing costs vary by lender and property. Confirm every number with your mortgage professional.
Investor snapshot
Income potential: the basement has a separate entrance, which often supports a rentable in-law or second suite. That can lift real rent well above the figure above and help carry the mortgage. Ask us about permitted use in this area.
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.
