Our TakeTeam Asgarian · Broker
A small discount is typical
$2.34Mlikely sale price

Listed at $2,388,888. Going by how homes in Bayview Northeast 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 $2.34M, if it sells. A realistic range is $2.19M to $2.63M.

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 listing describes a new or newly built home, and the public record (tax bill, size) can still describe what stood on the lot before.

  • 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.
  • Walk-out basement. Extra light, usable space, and income potential, so the estimate is a conservative floor for it.
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 $1.86M. Condition and finishes remain an in-person call.

  • Ravine lot: privacy and premium value, but confirm the buildable area and any conservation limits. Worth verifying

Read this with carewhy it’s an estimate, not an appraisal

Priced above comparable homes overall, but the price per square foot ($562/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.

There were not many closely comparable homes right in Bayview Northeast, so I widened the search to the surrounding area.

Based on 14 comparable homes that sold in Bayview Northeast over the past two years, from 71 closings there.
