Rooms
Listed at $2,000,000. Going by how homes in Rural King and the wider GTA have actually closed against their asking prices (about 96%, 13 local closings in 90 days), the likely sale price is near $1.91M, if it sells. A realistic range is $1.79M to $2.16M.
Independent value check: $1.66M. Without looking at the asking price, our model values the home itself about 17% below the ask (homes like it typically land between $1.55M and $1.74M).
Why $1.66M. The typical detached home sold in Rural King over the past year went for about $2.33M (40 sales). What sets this one apart:
- ▲ Raises it stronglyIt is 3,500 to 5,000 sq ft; the typical home sold here is 2,500 to 3,000.
- ▼ Lowers it stronglyIts tax bill, which follows the city's own assessment, is $6,855 a year; the typical home sold here pays about $8,900.
- ▲ Raises itThe listing describes it as fully renovated or newly built.
Total price vs nearby homes. Likely closing about $1.91M, from 13 recent closings in this pocket.
The market behind the math:
About 1.2 months of inventory: 5 detached homes for sale in the area against 13 closings in the last 90 days. Under two months favours sellers, over four favours buyers.
Price per square foot: this home lists at $471/sqft against an area asking average of $1,013/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 13 most comparable recent sales on their own, adjusted for size, beds, baths and lot, point to about $3.16M. Condition and finishes remain an in-person call.

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
- Renovated / rebuilt: recent work can mean fewer upfront costs, worth confirming the scope, quality, and that permits were pulled. Value driver
- Addition / added square footage: more space lifts value when it is permitted and well integrated, verify the permits. Value driver
Read this with carewhy it’s an estimate, not an appraisal
Priced above comparable homes overall, but the price per square foot ($471/sqft) is below the area, so you are paying for extra space rather than a premium.
The listing states size as a wide range, so the size adjustment is approximate and this estimate is a rough read. I can confirm exact square footage to tighten it.
Based on 13 comparable homes that sold in Rural King over the past two years, from 110 closings there.
Nothing closely matching this home is listed nearby right now, so these are the nearest detached listings on the market. Homes like this one have recently closed around $1.66M, which is where my estimate comes from.
Per square foot, these ask about $976/sqft; this home lists at $471/sqft. Size is part of the price story, not just the sticker.

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.

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 8 whole-home leases in Rural King signed at a median of $4,417 a month; adjusted to this home for size, beds and baths, and for where rents stood the month each signed, that is $5,439. 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.
