This is a rare parcel: about 1.87 acres. Comparable-sales math works on size and bedrooms, and here the lot is what is being sold, so no automatic estimate is shown.
Considering this property? Request a written price readThe assigned public school is R.L. Graham PS. EQAO is only one input, and families here also look at French Immersion, boundary, and private options, the full breakdown is below.
Nothing closely matching this home is listed nearby right now, so these are the nearest detached listings on the market. Homes like this one have recently closed around $1.57M, which is where my estimate comes from.
Per square foot, these ask about $426/sqft; this home lists at $1,571/sqft. Size is part of the price story, not just the sticker.

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 39 whole-home leases in Keswick South signed at a median of $3,529 a month; adjusted to this home for size, beds and baths, and for where rents stood the month each signed, that is $3,371. 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.
