Listed at $2,949,000, this home is about 14% below comparable homes, worth a close look. The number above is my independent estimate of value, not the asking price.
Based on 7 similar homes nearby, adjusted for size, beds, and baths.Median of 7 comparable active listings, adjusted for size, beds, and baths. The city (MPAC) assessment points to about $3.43M, a close match.
How I got there
Here is the exact math behind the estimate. I start from the closest comparable listing and adjust for the real differences (size, beds, baths) to land on a like-for-like value for this home.
- Closest comparable, listed at $3.85M
- Bathrooms +$15K
- Adjusts to $3.86M
That comparable adjusts to $3.86M; the $3.44M estimate above is the median of all 7 comparables, which is steadier than any single home.This uses comparable active listings, not sold prices. Lot, condition, and finishes are my in-person call, and I can run a full CMA with recent solds.
On location, this is a very walkable address with everyday errands close by. Third Line + Tansley Dr is about a 3-minute walk away. Walkable, transit-friendly spots tend to hold value and widen your resale pool.
Total price vs nearby homes. Fair value about $3.44M, median of 7 comparables.
What the listing highlightsThese are claims from the listing. The only way to know for sure is to see it in person, and I am happy to book you a private showing.
- Upscale kitchen: a genuine value driver, verify the appliances, stone, and finishes in person.
- Pool: lifestyle appeal, but adds maintenance, insurance, and resale is mixed.
- Premium lot / gardens: lot size and privacy hold value and cannot be changed, verify frontage, depth, and any easements.
- Primary suite: a key comfort and resale feature.
- Sold as-is / needs work: budget for renovation, the price should reflect the condition.

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.

Actual rates, taxes, insurance, and closing costs vary by lender and property. Confirm every number with your mortgage professional.
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 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.
