Listed at $1,250,000. Going by how homes in Middlefield and the wider GTA have actually closed against their asking prices (about 99%, 17 local closings in 90 days), the likely sale price is near $1.24M, if it sells. A realistic range is $1.16M to $1.39M.
Independent value check: $1.20M. Without looking at the asking price, our model values the home itself about 4% below the ask (homes like it typically land between $1.12M and $1.25M).
Why $1.20M. The typical detached home sold in Middlefield over the past year went for about $1.21M (79 sales). What sets this one apart:
- ▲ Raises it slightlyIts tax bill, which follows the city's own assessment, is $5,750 a year; the typical home sold here pays about $5,300.
Longer on the market than typical. 230 days on the market against about 17 for homes like it here, and asking 5% above where comparable closings put it.
Total price vs nearby homes. Likely closing about $1.24M, from 17 recent closings in this pocket.
The market behind the math:
About 1.1 months of inventory: 6 detached homes for sale in the area against 17 closings in the last 90 days. Under two months favours sellers, over four favours buyers.
Price per square foot: this home lists at $556/sqft against an area asking average of $552/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 17 most comparable recent sales on their own, adjusted for size, beds, baths and lot, point to about $1.12M. Condition and finishes remain an in-person call.

Investor snapshot
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 11 whole-home leases in Middlefield signed at a median of $3,803 a month; adjusted to this home for size, beds and baths, and for where rents stood the month each signed, that is $3,806. 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.
