What comes from where
Data refreshes daily rather than continuously. For the live status of one property, the listing agent is the only reliable source.
| What you see | Where it comes from |
|---|---|
| Listings and their details | TRREB board data through a RESO-compliant pipeline. |
| Market statistics and trends | Aggregated sold and active data for the area you are viewing. |
| Home value estimates | Comparable sales near the property, adjusted, with a confidence rating based on how many were found. |
| Calculator figures | Your inputs, plus statutory rates — tax brackets, rebate thresholds, the stress-test rate — and our stated assumptions where you did not supply something. |
What an automated estimate is blind to
- Condition. A home stripped to the studs and one freshly renovated look identical in the data.
- What has been done without a permit, which can reduce value rather than add it.
- Aspect, noise, and what is behind the fence.
- Anything that made the last comparable sale unusual — a private sale, a family transfer, a power of sale.
- A street that is genuinely different from the street one over.
Why we show a range and a confidence rating
A single number implies a precision that comparable-sales estimation does not have. The range is the honest output; the point estimate inside it is just the middle. The confidence rating tells you how many comparable sales the estimate rests on — under three, it is leaning on city-wide averages and should be read as a very wide range.
This is also why every calculator separates what you entered from what it assumed. An estimate built on six of your figures and two of ours is a different thing from one built on one of yours and seven of ours, and you cannot tell which you have unless we say.
