Listed at $1,238,888, this home is about 28% above what comparable homes suggest. The number above is my independent estimate of value, not the asking price.
Priced above comparable homes overall, but the price per square foot ($708/sqft) is in line with the area, so you are paying for extra space rather than a premium.
There were not many closely comparable homes right in Rouge River Estates, so I widened the search to the surrounding area.
Based on 9 similar homes nearby, adjusted for size, beds, and baths.Median of 9 comparable active listings, adjusted for size, beds, and baths. The city (MPAC) assessment points to about $954K, 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 $900K
- Bedrooms +$30K
- Adjusts to $930K
That comparable adjusts to $930K; the $969K estimate above is the median of all 9 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.
Its public catchment (Markham District HS) tests around the provincial average, a steady, family-friendly draw. The full EQAO breakdown is below.
On location, this is a very walkable address with everyday errands close by. 14th Av / Horstman St is about a 1-minute walk away. Walkable, transit-friendly spots tend to hold value and widen your resale pool.
Total price vs nearby homes. Fair value about $969K, median of 9 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.
