Why $1.32M. The typical detached home sold in Aileen-Willowbrook over the past year went for about $1.43M (35 sales). On tax assessment, size, rooms and lot, this one is close to that typical home.
Total price vs nearby homes. Fair value about $1.32M, learned from recent GTA sales.
The market behind the math:
About 6 months of inventory: 8 detached homes for sale in the area against 4 closings in the last 90 days. Under two months favours sellers, over four favours buyers.
Price per square foot: this home lists at $702/sqft against an area asking average of $818/sqft.
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 42 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.

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
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 14 whole-home leases in Aileen-Willowbrook signed at a median of $4,007 a month; adjusted to this home for size, beds and baths, and for where rents stood the month each signed, that is $4,030. 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.
