Listed at $1,799,000, this home is within the range of comparable homes, on the lower side. The number above is my independent estimate of value, not the asking price.
There were not many closely comparable homes right in Box Grove, so I widened the search to the surrounding area.
Based on 16 similar homes nearby, adjusted for size, beds, and baths.Median of 16 comparable active listings, adjusted for size, beds, and baths. The city (MPAC) assessment points to about $1.74M, a bit lower. 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 $1.77M
- Bedrooms −$30K
- Bathrooms +$15K
- Adjusts to $1.75M
That comparable adjusts to $1.75M; the $1.96M estimate above is the median of all 16 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 Legacy 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, this is a very walkable address with everyday errands close by. Copper Creek Dr / Boswell Rd is about a 2-minute walk away. Walkable, transit-friendly spots tend to hold value and widen your resale pool.
Total price vs nearby homes. Fair value about $1.96M, median of 16 comparables.

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.
