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 10 most comparable recent sales on their own, adjusted for size, beds, baths and lot, point to about $1.05M. Condition and finishes remain an in-person call.

Read this with carewhy it’s an estimate, not an appraisal
Priced above comparable homes overall, but the price per square foot ($542/sqft) is in line with the area, so you are paying for extra space rather than a premium.
There were not many closely comparable homes right in Sonoma Heights, so I widened the search to the surrounding area.
Based on 10 comparable homes that sold in Sonoma Heights over the past two years, from 37 closings there.
Nothing closely matching this home is listed nearby right now, so these are the nearest semi-detached listings on the market. Homes like this one have recently closed around $1.07M, which is where my estimate comes from.
Per square foot, these ask about $597/sqft; this home lists at $542/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 11 whole-home leases in Sonoma Heights signed at a median of $3,565 a month; adjusted to this home for size, beds and baths, and for where rents stood the month each signed, that is $4,284. 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.
