Listed at $1,189,999. My estimate lands at $1.15M. The ask is about 3% ahead of that, which usually means the seller is pricing in the finishes, the lot, or simply room to negotiate. Worth a close look at what justifies it before you offer.
Total price vs nearby homes. Fair value about $1.15M, median of 5 comparables.
The market behind the math:
Price per square foot: this home lists at $433/sqft against an area asking average of $455/sqft. Size and $/sqft both feed the estimate above.
How this estimate is builtthe short version
I take the 5 most comparable recent listings nearby and adjust each one to this home for the real differences (size, beds, baths, garage, and standout features), 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 $1.20M, a close match.

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
- Finished basement: added living space, worth checking ceiling height and that the work was permitted. Value driver
- Tall ceilings: they transform how a home feels, worth confirming the actual heights room to room. Worth verifying
- Transit / schools nearby: convenience and resale support, verify the exact distances and school catchment. Value driver

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.

Talk to Team Asgarian about your options
Rates and programs change often. We will connect you with a trusted mortgage professional and build a plan that fits your budget and goals.
Estimates only, not a mortgage quote or pre-approval. Figures use Canadian semi-annual compounding, current minimum down-payment rules, CMHC premium tiers, and Ontario (plus Toronto, when selected) land transfer tax. Actual rates, taxes, insurance, and closing costs vary by lender and property. Confirm every number with your mortgage professional.
Investor snapshot
Income potential: the basement has a separate entrance, which often supports a rentable in-law or second suite. That can lift real rent well above the figure above and help carry the mortgage. Ask us about permitted use in this area.
Thinking of this home as an investment? We will pull real comparable rents and run the full numbers with you.
Talk about the numbersEstimates only. Rent is modelled on above-grade size and local norms, so a finished basement or second suite (a separate entrance often means one) can push real rent well above this. Taxes, fees, and vacancy vary by property, and cap rate is before financing. A starting point, not a final number, let us run the real ones with you.
