Our 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.

Worth noting: this home has a walk-up basement, a premium feature (light, usable space, income potential) that comparable-sales math tends to under-price. I will factor it in when I pull your comparables.

On schools, this address is zoned for Lawrence Park 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.

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.
