Listed at $2,239,000, this home is within the range of comparable homes, on the higher side. The number above is my independent estimate of value, not the asking price.
In Banbury-Don Mills lately, sellers have been getting about 95% of asking and homes sell in about 43 days.
There were not many closely comparable homes right in Banbury-Don Mills, so I widened the search to the surrounding area.
Based on 44 similar homes that recently sold nearby, adjusted for size, beds, and baths.Median of 44 recently sold comparable homes — actual closing prices, not asks — adjusted for size, beds, and baths. The city (MPAC) assessment points to about $2.40M, a bit higher.
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, sold for $1.81M
- Adjusts to $1.81M
That comparable adjusts to $1.81M; the $2.07M estimate above is the median of all 44 comparables, which is steadier than any single home.This estimate is grounded in actual closing prices from the last 15 months, not asking prices. Lot, condition, and finishes are still my in-person call.
On schools, this address is zoned for York Mills Collegiate Institute, one of the higher-rated public schools in the area. A strong catchment tends to hold value and widen your resale pool, especially with family buyers.
Total price vs nearby homes. Fair value about $2.07M, median of 44 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.

- 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
- Hardwood floors: quality hardwood is durable and broadly desirable. Lifestyle
- Transit / schools nearby: convenience and resale support, verify the exact distances and school catchment. Value driver

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

Actual rates, taxes, insurance, and closing costs vary by lender and property. Confirm every number with your mortgage professional.
Investor snapshot
Income potential: the basement has a separate entrance, which often supports a rentable in-law or second suite. That can lift real rent well above the figure above and help carry the mortgage. Ask us about permitted use in this area.
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.
