Listed at $5,500,000 with no offer date, so the ask is the seller’s number, and homes priced this way sell close to it. My read is $5.47M, typically $5.06M to $6.54M. Comparable listings on their own put this home around $5.41M, which agrees with the ask, so this is a firm read.
Second read, from the city assessment: $6.40M. That is about 18% above the comparable-sales figure. When my two methods disagree this much, the answer usually sits between them and something about this home is not in the comparables (the lot, the condition, a rebuild). I would want to see it before leaning on either number.
Total price vs nearby homes. Fair value about $5.47M, median of 9 comparables.
The market behind the math:
About 3.3 months of inventory: 25 detached homes for sale in the area against 23 closings in the last 90 days. Under two months favours sellers, over four favours buyers.
Price per square foot: this home lists at $1,100/sqft against an area asking average of $1,242/sqft. Size and $/sqft both feed the estimate above.
- Walk-out basement apartment features. A finished 1 bed walk-out basement apartment. A self-contained space for extended family, guests or potential income. In St. Andrew-Windfields basements rarely rent out (5 of 133 recent detached leases were basement units), so buyers here treat a suite as family or nanny space rather than income. Value it for the living space, not the rent. Second-suite retrofit status is not verified. A buyer intending to rent should confirm requirements with the City of Toronto.
How this estimate is builtthe short version
I take the 9 most comparable recent listings nearby and adjust each one to this home for the real differences (size, beds, baths, garage, lot frontage, a ravine backing, an inground pool), then use the median, which is steadier than leaning on any single listing.
It’s grounded in comparable active listings. Lot, condition, and finishes are my in-person call, and the city (MPAC) assessment points to about $6.40M, a bit higher.

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.

Investor snapshot
About the suite: in St. Andrew-Windfields basements rarely rent out (5 of 133 recent detached leases were basement units), so the figure above does not count it as income. Buyers here use a suite as family or nanny space.
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 33 whole-home leases in St. Andrew-Windfields signed at a median of $7,041 a month; adjusted to this home for size, beds and baths, and for where rents stood the month each signed, that is $8,112. 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.
