Listed at $6,999,000, this home is within the range of a wider set of listings, but with few close matches nearby, so worth confirming with 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 6 similar homes nearby, adjusted for size, beds, and baths.Median of 6 comparable active listings, adjusted for size, beds, and baths. The city (MPAC) assessment points to about $9.87M, higher than the comparables and worth a second look. 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 $10.80M
- Adjusts to $10.80M
That comparable adjusts to $10.80M; the $5.97M estimate above is the median of all 6 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 (Kettleby PS) tests around the provincial average, a steady, family-friendly draw. The full EQAO breakdown is below.
On location, this is a more car-dependent spot, so buyers here typically drive. Newmarket Bus Stop is about a 48-minute walk away. Worth weighing if transit access matters to you.
Total price vs nearby homes. Fair value about $5.97M, median of 6 comparables.

Estimates only, not a mortgage quote or pre-approval.

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.
