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.

On schools, this address is zoned for York Mills Collegiate Institute, 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. Bannatyne Dr at Dunlace Dr 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.

  • Upscale kitchen: a genuine value driver, verify the appliances, stone, and finishes in person.
  • Heated floors: comfort and a premium-finish signal.
  • 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.
  • Premium lot / gardens: lot size and privacy hold value and cannot be changed, verify frontage, depth, and any easements.
  • Value driver
  • Lifestyle
  • Weigh carefully
  • Worth verifying

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.
