Listed at $1,649,900. Going by how homes in Cornell and the wider GTA have actually closed against their asking prices (about 99%, 14 local closings in 90 days), the likely sale price is near $1.63M, if it sells. A realistic range is $1.53M to $1.84M.
Independent value check: $1.48M. Without looking at the asking price, our model values the home itself about 10% below the ask (homes like it typically land between $1.39M and $1.55M).
Why $1.48M. The typical detached home sold in Cornell over the past year went for about $1.27M (66 sales). What sets this one apart:
- ▲ Raises itIts tax bill, which follows the city's own assessment, is $7,710 a year; the typical home sold here pays about $5,800.
- ▲ Raises itThe listing describes it as fully renovated or newly built.
- ▲ Raises it slightlyIt is 3,000 to 3,500 sq ft; the typical home sold here is 2,000 to 2,500.
Total price vs nearby homes. Likely closing about $1.63M, from 14 recent closings in this pocket.
The market behind the math:
About 4.3 months of inventory: 20 detached homes for sale in the area against 14 closings in the last 90 days. Under two months favours sellers, over four favours buyers.
Price per square foot: this home lists at $508/sqft against an area asking average of $565/sqft.
- Corner lot. Two street frontages: more to landscape, shovel and mow, and more exposure to traffic, wind and headlights at night. Buyers price that against an interior lot on the same street, so I read this one on the cautious side and confirm the setting in person.
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 14 most comparable recent sales on their own, adjusted for size, beds, baths and lot, point to about $1.46M. 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.
- Open-concept layout: modern, sought-after flow. Lifestyle
- Hardwood floors: quality hardwood is durable and broadly desirable. Lifestyle
- Corner lot: more light and frontage, sometimes at the cost of privacy. Weigh carefully
Read this with carewhy it’s an estimate, not an appraisal
Priced above comparable homes overall, but the price per square foot ($508/sqft) is below the area, so you are paying for extra space rather than a premium.

Affordability & Mortgage
Income needed assumes a ~32% GDS ratio; weekly is mortgage principal & interest only. Price ÷ income is the home price over the income needed. Fixed reference assumptions so listings compare on equal footing, not a lending decision.

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
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 50 whole-home leases in Cornell signed at a median of $3,608 a month; adjusted to this home for size, beds and baths, and for where rents stood the month each signed, that is $4,238. 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.
