Access To Garage
Listed at $1,298,000, about 7% above our estimate of $1.22M (homes like it typically land between $1.14M and $1.28M).
Why $1.22M. The typical detached home sold in Armitage over the past year went for about $1.24M (21 sales). What sets this one apart:
- ▲ Raises itThe listing describes it as fully renovated or newly built.
- ▼ Lowers it slightlyIt is 2,000 to 2,500 sq ft; the typical home sold here is 2,500 to 3,000.
Longer on the market than typical. 105 days on the market, and asking 7% above where comparable closings put it.
Total price vs nearby homes. Fair value about $1.22M, learned from recent GTA sales.
The market behind the math:
Price per square foot: this home lists at $577/sqft against an area asking average of $514/sqft.
- Walk-out basement apartment features. A finished 1 bed walk-out basement apartment with a second kitchen. A self-contained space for extended family, guests or potential income. Basements do rent in Armitage: 11 of the 46 detached leases here lately were basement units, around $1,990 a month. That makes the suite real income. Second-suite retrofit status is not verified. A buyer intending to rent should confirm requirements with the Town of Newmarket.
How this estimate is builtthe short version
This figure comes from a model built on about 44,000 recent GTA sales. It weighs this home’s tax assessment, size, age, location and features against what homes like it actually sold for, including sales in this neighbourhood.
It never sees the asking price. The 12 most comparable recent sales on their own, adjusted for size, beds, baths and lot, point to about $1.19M. Condition and finishes remain an in-person call.

Claims from the listing, worth confirming in person. I can book you a private showing.

Investor snapshot
The suite is real income here: basements rent in Armitage (11 of 46 recent detached leases were basement units, around $1,990 a month). The figure above is the whole house on one lease; rented as two units, the suite alone brings about $1,990 a month on top of the upper floors. Permitted use is worth confirming with the city.
Thinking of this home as an investment? We will pull real comparable rents and run the full numbers with you.
Talk about the numbersThe last 9 whole-home leases in Armitage signed at a median of $3,911 a month; adjusted to this home for size, beds and baths, and for where rents stood the month each signed, that is $3,524. The gross yield above is on the asking price, before taxes and upkeep; the cap rate is after them. A finished basement or second suite can push real rent above it. Taxes, fees, and vacancy vary by property, and cap rate is before financing.
