Rooms
Listed at $2,000,000, this home is about 24% below comparable homes, worth a close look. The number above is my independent estimate of value, not the asking price.
There were not many closely comparable homes right in Rural King, 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 $1.38M, lower 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 $3.36M
- Bedrooms +$30K
- Adjusts to $3.39M
That comparable adjusts to $3.39M; the $2.63M 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.
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 24-minute walk away. Worth weighing if transit access matters to you.
Total price vs nearby homes. Fair value about $2.63M, median of 16 comparables.
What the listing highlightsThese are claims from the listing. The only way to know for sure is to see it in person, and I am happy to book you a private showing.
- Separate entrance / basement suite: rental or in-law income potential, if it is legally registered and retrofit-compliant.
- Renovated / rebuilt: recent work can mean fewer upfront costs, worth confirming the scope, quality, and that permits were pulled.
- Addition / added square footage: more space lifts value when it is permitted and well integrated, verify the permits.

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.
