Listed at $2,799,000. Going by how homes in St. Andrew-Windfields and the wider GTA have actually closed against their asking prices (about 96%, 25 local closings in 90 days), the likely sale price is near $2.70M, if it sells. A realistic range is $2.53M to $3.04M.
Independent value check: no figure for this home. Going only by the sales record, our model lands more than 25% below the ask. At that distance an automated figure has rarely been close to the eventual sale price, so we are not printing one. The usual reason is something the record cannot show: a rebuild, a second unit, or a lot or setting unlike the homes around it.
Total price vs nearby homes. Likely closing about $2.70M, from 25 recent closings in this pocket.
The market behind the math:
About 0.6 months of inventory: 5 detached homes for sale in the area against 25 closings in the last 90 days. Under two months favours sellers, over four favours buyers.
Price per square foot: this home lists at $1,244/sqft against an area asking average of $834/sqft.
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 25 most comparable recent sales on their own, adjusted for size, beds, baths and lot, point to about $2.13M. Condition and finishes remain an in-person call.
