Listed at $1,149,900. Going by how homes in Summerhill Estates and the wider GTA have actually closed against their asking prices (about 98%, 14 local closings in 90 days), the likely sale price is near $1.12M, if it sells. A realistic range is $1.05M to $1.26M.
Independent value check: $1.23M. Without looking at the asking price, our model values the home itself about 7% above the ask (homes like it typically land between $1.15M and $1.29M).
Why $1.23M. The typical detached home sold in Summerhill Estates over the past year went for about $1.06M (49 sales). What sets this one apart:
- ▲ Raises it stronglyIts tax bill, which follows the city's own assessment, is $6,691 a year; the typical home sold here pays about $5,900.
- ▲ Raises itThe listing describes it as fully renovated or newly built.
- ▲ Raises it slightlyIt is 2,000 to 2,500 sq ft; the typical home sold here is 1,500 to 2,000.
Total price vs nearby homes. Likely closing about $1.12M, from 14 recent closings in this pocket.
The market behind the math:
About 2.6 months of inventory: 12 detached homes for sale in the area against 14 closings in the last 90 days. Under two months favours sellers, over four favours buyers.
Price per square foot: this home lists at $511/sqft against an area asking average of $576/sqft.
- Ravine / green setting. This home is described as backing onto a ravine or green setting. The ravine backing is priced into the comparison. How much it is really worth depends on whether the house sits on table land with the slope well behind it, or drops away right behind it, and that part 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 14 most comparable recent sales on their own, adjusted for size, beds, baths and lot, point to about $1.14M. Condition and finishes remain an in-person call.
