Price and status history from the listing board. Deemed reliable but not guaranteed.
Listed at $3,950,000, this home is tracking about 28% 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 45 similar homes nearby, adjusted for size, beds, and baths.Median of 45 comparable active listings, adjusted for size, beds, and baths. The city (MPAC) assessment points to about $5.61M, 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 $2.45M
- Bathrooms −$45K
- Adjusts to $2.40M
That comparable adjusts to $2.40M; the $3.08M estimate above is the median of all 45 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 Franklin Street 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. Main St Markham North at Robinson St 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 $3.08M, median of 45 comparables.

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.
