Listed at $4,265,000, this home is about 21% above what comparable homes suggest. The number above is my independent estimate of value, not the asking price.
Priced above comparable homes overall, but the price per square foot ($1,312/sqft) is in line with the area, so you are paying for extra space rather than a premium.
There were not many closely comparable homes right in Old Oakville, so I widened the search to the surrounding area.
Based on 5 similar homes nearby, adjusted for size, beds, and baths.Median of 5 comparable active listings, adjusted for size, beds, and baths. The city (MPAC) assessment points to about $2.16M, lower 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 $3.50M
- Bathrooms +$15K
- Adjusts to $3.51M
That comparable adjusts to $3.51M; the $3.51M estimate above is the median of all 5 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. MacDonald Rd + Watson Ave is about a 1-minute walk away. Walkable, transit-friendly spots tend to hold value and widen your resale pool.
Total price vs nearby homes. Fair value about $3.51M, median of 5 comparables.

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.

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.
