Listed at $1,550,000. Going by how homes in King City and the wider GTA have actually closed against their asking prices (about 97%, 17 local closings in 90 days), the likely sale price is near $1.50M, if it sells. A realistic range is $1.40M to $1.69M.
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 $1.50M, from 17 recent closings in this pocket.
The market behind the math:
About 1.4 months of inventory: 8 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 $1,192/sqft against an area asking average of $1,698/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 $1.66M. Condition and finishes remain an in-person call.
What the listing highlights3 points to weigh
Claims from the listing, worth confirming in person. I can book you a private showing.
- Renovated / rebuilt: recent work can mean fewer upfront costs, worth confirming the scope, quality, and that permits were pulled. Value driver
- Pool: lifestyle appeal, but adds maintenance, insurance, and resale is mixed. Weigh carefully
- Development potential: upside only if zoning permits, verify with the city before relying on it. Worth verifying
Read this with carewhy it’s an estimate, not an appraisal

Affordability & Mortgage
Income needed assumes a ~32% GDS ratio; weekly is mortgage principal & interest only. Price ÷ income is the home price over the income needed. Fixed reference assumptions so listings compare on equal footing, not a lending decision.

Estimates only, not a mortgage quote or pre-approval.

Actual rates, taxes, insurance, and closing costs vary by lender and property. Confirm every number with your mortgage professional.
Investor snapshot
About the suite: in King City basements rarely rent out (4 of 61 recent detached leases were basement units), so the figure above does not count it as income. Buyers here use a suite as family or nanny space.
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 10 whole-home leases in King City signed at a median of $3,276 a month; adjusted to this home for size, beds and baths, and for where rents stood the month each signed, that is $3,100. 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.
