Listed at $1,298,000, this home is tracking about 5% below a wider set of listings, though close matches were thin, so it is worth confirming with a precise CMA rather than reading it as a clear deal. 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 8 similar homes nearby, adjusted for size, beds, and baths.Median of 8 comparable active listings, adjusted for size, beds, and baths. The city (MPAC) assessment points to about $1.54M, a bit higher.
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 $999K
- Bedrooms −$30K
- Bathrooms −$30K
- Adjusts to $939K
That comparable adjusts to $939K; the $1.37M estimate above is the median of all 8 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.

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.
