Moe’s TakeTeam Asgarian · Broker
Worth a personal read

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.

Its public catchment (York Mills Collegiate Institute) tests around the provincial average, a steady, family-friendly draw. The full EQAO breakdown is below.

On location, it is moderately walkable, so some daily errands are within reach and for the rest you will likely drive. Lawrence Ave East at The Bridle Path is about a 5-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.

  • Ravine lot: privacy and premium value, but confirm the buildable area and any conservation limits.
  • 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.
  • Tall ceilings: they transform how a home feels, worth confirming the actual heights room to room.
  • Hardwood floors: quality hardwood is durable and broadly desirable.
  • Worth verifying
  • Value driver
  • Weigh carefully

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.

Income potential: the basement has a separate entrance, which often supports a rentable in-law or second suite. That can lift real rent well above the figure above and help carry the mortgage. Ask us about permitted use in this area.

Thinking of this home as an investment? We will pull real comparable rents and run the full numbers with you.

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.
