Listed at $1,075,000. Going by how homes in Banbury-Don Mills and the wider GTA have actually closed against their asking prices (about 98%, 6 local closings in 90 days), the likely sale price is near $1.05M, if it sells. A realistic range is $987K to $1.13M.
Independent value check: $949K. Without looking at the asking price, our model values the home itself about 12% below the ask (homes like it typically land between $883K and $998K).
Why $949K. The typical townhouse sold in Banbury-Don Mills over the past year went for about $790K (12 sales). What sets this one apart:
- ▲ Raises it stronglyIts tax bill, which follows the city's own assessment, is $5,072 a year; the typical home sold here pays about $3,900.
- ▲ Raises itIt is 1,400 to 1,599 sq ft; the typical home sold here is 1,100 to 1,299.
Longer on the market than typical. 48 days on the market against about 32 for homes like it here, and asking 13% above where comparable closings put it.
Total price vs nearby homes. Likely closing about $1.05M, from 6 recent closings in this pocket.
The market behind the math:
Price per square foot: this home lists at $717/sqft against an area asking average of $608/sqft.
- Ravine / green setting. This home is described as backing onto a ravine or green setting. The ravine backing is priced into the comparison. How much it is really worth depends on whether the house sits on table land with the slope well behind it, or drops away right behind it, and that part is my in-person call.
- Walk-out basement. Extra light, usable space, and income potential, so the estimate is a conservative floor for it.
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 and this building.
It never sees the asking price. The 6 most comparable recent sales on their own, adjusted for size, beds, baths and lot, point to about $937K. Condition and finishes remain an in-person call.
What the listing highlights3 points to weigh
Claims from the listing, worth confirming in person. I can book you a private showing.
- Ravine lot: privacy and premium value, but confirm the buildable area and any conservation limits. Worth verifying
- Renovated / rebuilt: recent work can mean fewer upfront costs, worth confirming the scope, quality, and that permits were pulled. Value driver
- Premium lot / gardens: lot size and privacy hold value and cannot be changed, verify frontage, depth, and any easements. Value driver

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 numbersThe last 9 whole-home leases in Banbury-Don Mills signed at a median of $3,900 a month; adjusted to this home for size, beds and baths, and for where rents stood the month each signed, that is $3,900. 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.
