Listed at $1,298,000 with no offer date. Homes here have been closing close to ask, so my read is $1.21M, typically $1.16M to $1.26M. Comparable closings on their own put this home around $1.33M, which supports the ask, so this is a firm read.
Total price vs nearby homes. Likely closing about $1.21M, from 5 recent closings in this pocket.
The market behind the math:
About 8.4 months of inventory: 14 detached homes for sale in the area against 5 closings in the last 90 days. Under two months favours sellers, over four favours buyers.
Price per square foot: this home lists at $742/sqft against an area asking average of $1,016/sqft. Size and $/sqft both feed the estimate above.
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 5 most comparable recent sales on their own, adjusted for size, beds, baths and lot, point to about $1.34M. Condition and finishes remain an in-person call.
Schools & getting aroundcatchment and transit
Its public catchment (Thornhill SS) tests around the provincial average, a steady, family-friendly draw. The full EQAO breakdown is below.
Read this with carewhy it’s an estimate, not an appraisal
There were not many closely comparable homes right in Thornhill, so I widened the search to the surrounding area.
Based on 5 comparable homes that sold in Thornhill over the past two years, from 32 closings there.
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 $1.33M, which is where my estimate comes from.
Per square foot, these ask about $970/sqft; this home lists at $742/sqft. Size is part of the price story, not just the sticker.

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 7 whole-home leases in Thornhill signed at a median of $4,424 a month; adjusted to this home for size, beds and baths, and for where rents stood the month each signed, that is $4,524. 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.
