Above the wider set
$2.80Mest. value

Listed at $3,549,000, this home is tracking about 27% above a wider set of listings, though close matches were thin, so treat this as a rough read until I run a precise CMA. The number above is my independent estimate of value, not the asking price.

There are only a few closely comparable homes right here, so this is a broad read from wider listings in the area. Ask me for a precise CMA before relying on it.

Based on 16 similar homes nearby, adjusted for size, beds, and baths.Median of 16 comparable active listings, adjusted for size, beds, and baths. The city (MPAC) assessment points to about $3.90M, higher than the comparables and worth a second look.

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 $1.65M
  • Size difference +$944K
  • Bedrooms +$90K
  • Bathrooms +$75K
  • Adjusts to $2.76M

That comparable adjusts to $2.76M; the $2.80M estimate above is the median of all 16 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 schools, this address is zoned for David Suzuki PS, one of the higher-rated public schools in the area. A strong catchment tends to hold value and widen your resale pool, especially with family buyers.

On location, it is moderately walkable, so some daily errands are within reach and for the rest you will likely drive. Riverwalk Dr / Ninth Line is about a 4-minute walk away.

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.
  • Premium lot / gardens: lot size and privacy hold value and cannot be changed, verify frontage, depth, and any easements.
  • Elevator: rare and valuable for accessibility and resale.

Estimates only, not a mortgage quote or pre-approval.

Talk about the numbers

Estimates 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.
