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 19 most comparable recent sales on their own, adjusted for size, beds, baths and lot, point to about $947K. Condition and finishes remain an in-person call.

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 132 whole-home leases in Cornell signed at a median of $3,188 a month; adjusted to this home for size, beds and baths, and for where rents stood the month each signed, that is $3,304. 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.
