Rooms
Heads up: the asking price here sits well above what comparable listings suggest. That can point to premium finishes, a bigger lot, or simply an ambitious ask, so it is worth a close look before you offer. I would not put an automatic figure on this one. Tell me you are interested and I will pull the most comparable recent sales and give you a straight answer on what it will really take.
Ask Moe if this price is fairIts public catchment (Aurora HS) tests around the provincial average, a steady, family-friendly draw. The full EQAO breakdown is below.
On location, this is a more car-dependent spot, so buyers here typically drive. Wellington St / Bathurst St is about a 29-minute walk away. Worth weighing if transit access matters to you.
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.
- Renovated / rebuilt: recent work can mean fewer upfront costs, worth confirming the scope, quality, and that permits were pulled.
- 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.
- Elevator: rare and valuable for accessibility and resale.

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.
