Listed at $1,450,000. Going by how homes in Bullock and the wider GTA have actually closed against their asking prices (about 97%, 10 local closings in 90 days), the likely sale price is near $1.40M, if it sells. A realistic range is $1.31M to $1.58M.
Independent value check: $1.33M. Without looking at the asking price, our model values the home itself about 8% below the ask (homes like it typically land between $1.25M and $1.40M).
Why $1.33M. The typical detached home sold in Bullock over the past year went for about $1.16M (33 sales). What sets this one apart:
- ▲ Raises itThe listing describes it as fully renovated or newly built.
- ▲ Raises it3+2 bedrooms and 4 baths, against 3+1 and 2 typically.
- ▲ Raises itIt is 1,500 to 2,000 sq ft; the typical home sold here is 1,100 to 1,500.
Longer on the market than typical. 133 days on the market against about 30 for homes like it here, and asking 9% above where comparable closings put it.
Total price vs nearby homes. Likely closing about $1.40M, from 10 recent closings in this pocket.
The market behind the math:
About 2.4 months of inventory: 8 detached homes for sale in the area against 10 closings in the last 90 days. Under two months favours sellers, over four favours buyers.
Price per square foot: this home lists at $829/sqft against an area asking average of $761/sqft.
- Separate-entrance basement apartment features. A finished 2 bed basement apartment with a separate entrance and a second kitchen. A self-contained space for extended family, guests or potential income. Basements do rent in Bullock: 10 of the 64 detached leases here lately were basement units, around $1,975 a month. That makes the suite real income. Second-suite retrofit status is not verified. A buyer intending to rent should confirm requirements with the City of Markham.
- Park / green-space backing. The listing says this home backs onto or abuts a park or green space. That privacy is priced into the comparison. What is actually behind the fence, and how the lot sits against it, is my in-person call.
How this estimate is builtthe short version
This figure comes from a model built on about 44,000 recent GTA sales. It weighs this home’s tax assessment, size, age, location and features against what homes like it actually sold for, including sales in this neighbourhood.
It never sees the asking price. The 10 most comparable recent sales on their own, adjusted for size, beds, baths and lot, point to about $1.22M. Condition and finishes remain an in-person call.
What the listing highlights2 points to weigh
Claims from the listing, worth confirming in person. I can book you a private showing.
- Separate entrance / basement suite: rental or in-law income potential, if it is legally registered and retrofit-compliant. Income potential
- Hardwood floors: quality hardwood is durable and broadly desirable. Lifestyle

Investor snapshot
The suite is real income here: basements rent in Bullock (10 of 64 recent detached leases were basement units, around $1,975 a month). The figure above is the whole house on one lease; rented as two units, the suite alone brings about $1,975 a month on top of the upper floors. Permitted use is worth confirming with the city.
Thinking of this home as an investment? We will pull real comparable rents and run the full numbers with you.
Talk about the numbersThe last 23 whole-home leases in Bullock signed at a median of $3,626 a month; adjusted to this home for size, beds and baths, and for where rents stood the month each signed, that is $4,024. The gross yield above is on the asking price, before taxes and upkeep; the cap rate is after them. A finished basement or second suite can push real rent above it. Taxes, fees, and vacancy vary by property, and cap rate is before financing.
