Listed at $2,238,000. Going by how homes in Banbury-Don Mills and the wider GTA have actually closed against their asking prices (about 96%, 21 local closings in 90 days), the likely sale price is near $2.15M, if it sells. A realistic range is $2.01M to $2.42M.
Independent value check: $2.28M. Without looking at the asking price, our model values the home itself in line with the ask (homes like it typically land between $2.14M and $2.39M).
Why $2.28M. The typical detached home sold in Banbury-Don Mills over the past year went for about $2.30M (83 sales). What sets this one apart:
- ▼ Lowers itIt is 2,000 to 2,500 sq ft; the typical home sold here is 2,500 to 3,000.
- ▼ Lowers it slightlyIts lot is 45 by 112 ft; the typical lot sold here is 60 by 120.
Total price vs nearby homes. Likely closing about $2.15M, from 21 recent closings in this pocket.
The market behind the math:
About 5.6 months of inventory: 39 detached homes for sale in the area against 21 closings in the last 90 days. Under two months favours sellers, over four favours buyers.
Price per square foot: this home lists at $995/sqft against an area asking average of $1,147/sqft.
- Walk-out basement apartment features. A finished 1 bed walk-out basement apartment. A self-contained space for extended family, guests or potential income. In Banbury-Don Mills basements rarely rent out (7 of 155 recent detached leases were basement units), so buyers here treat a suite as family or nanny space rather than income. Value it for the living space, not the rent. Second-suite retrofit status is not verified. A buyer intending to rent should confirm requirements with the City of Toronto.
- Park / green-space backing. The listing says this home backs onto or abuts a park or green space. That privacy is priced into the comparison. What is actually behind the fence, and how the lot sits against it, is my in-person call.
- Inground pool. Priced into the comparison on the assumption it is clean and modern. A pool costs more to build than resale pays back, and condition is the in-person call.
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 21 most comparable recent sales on their own, adjusted for size, beds, baths and lot, point to about $2.21M. Condition and finishes remain an in-person call.
What the listing highlights5 points to weigh
Claims from the listing, worth confirming in person. I can book you a private showing.
- Renovated / rebuilt: recent work can mean fewer upfront costs, worth confirming the scope, quality, and that permits were pulled. Value driver
- Pool: lifestyle appeal, but adds maintenance, insurance, and resale is mixed. Weigh carefully
- Premium lot / gardens: lot size and privacy hold value and cannot be changed, verify frontage, depth, and any easements. Value driver
- Primary suite: a key comfort and resale feature. Lifestyle
- Hardwood floors: quality hardwood is durable and broadly desirable. Lifestyle

Investor snapshot
About the suite: in Banbury-Don Mills basements rarely rent out (7 of 155 recent detached leases were basement units), so the figure above does not count it as income. Buyers here use a suite as family or nanny space.
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 37 whole-home leases in Banbury-Don Mills signed at a median of $5,714 a month; adjusted to this home for size, beds and baths, and for where rents stood the month each signed, that is $5,343. 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.
