Listed at $1,988,800, about 4% below our estimate of $2.06M (homes like it typically land between $1.93M and $2.16M).
Why $2.06M. The typical detached home sold in Aileen-Willowbrook over the past year went for about $1.43M (35 sales). What sets this one apart:
- ▲ Raises it stronglyIts tax bill, which follows the city's own assessment, is $10,602 a year; the typical home sold here pays about $7,000.
- ▲ Raises itIt is 2,500 to 3,000 sq ft; the typical home sold here is 2,000 to 2,500.
Total price vs nearby homes. Fair value about $2.06M, 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 $723/sqft against an area asking average of $816/sqft.
- Separate-entrance basement apartment features. A finished 2 bed basement apartment with a separate entrance and a second kitchen. A self-contained space for extended family, guests or potential income. Basements do rent in Aileen-Willowbrook: 14 of the 50 detached leases here lately were basement units, around $1,998 a month. That makes the suite real income. Second-suite retrofit status is not verified. A buyer intending to rent should confirm requirements with the City of Markham.
- Ravine / green setting. This home is described as backing onto a ravine or green setting. The ravine backing is priced into the comparison. How much it is really worth depends on whether the house sits on table land with the slope well behind it, or drops away right behind it, and that part is my in-person call.
- Inground pool. Priced into the comparison on the assumption it is clean and modern. A pool costs more to build than resale pays back, and condition is the in-person call.
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 28 most comparable recent sales on their own, adjusted for size, beds, baths and lot, point to about $1.82M. Condition and finishes remain an in-person call.
What the listing highlights5 points to weigh
Claims from the listing, worth confirming in person. I can book you a private showing.
- Separate entrance / basement suite: rental or in-law income potential, if it is legally registered and retrofit-compliant. Income potential
- Ravine lot: privacy and premium value, but confirm the buildable area and any conservation limits. Worth verifying
- Pool: lifestyle appeal, but adds maintenance, insurance, and resale is mixed. Weigh carefully
- Transit / schools nearby: convenience and resale support, verify the exact distances and school catchment. Value driver
- Sold as-is / needs work: budget for renovation, the price should reflect the condition. Weigh carefully

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
The suite is real income here: basements rent in Aileen-Willowbrook (14 of 50 recent detached leases were basement units, around $1,998 a month). The figure above is the whole house on one lease; rented as two units, the suite alone brings about $1,998 a month on top of the upper floors. Permitted use is worth confirming with the city.
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 10 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 $4,357. 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.
