The website gives you a number. It looks precise, and it is tempting to build your next move around it. But a number on a screen is not an offer from a buyer—and it is not a promise about what will be left in your account after selling.
Precision is not the same as certainty
An automated valuation model uses data and a model to estimate a property's value. The result depends on the information available and the way the model uses it. A detailed-looking figure does not tell you, by itself, whether the model has the right floor area, current condition or suitable comparison properties.
That does not make every online estimate wrong. It means you should ask what supports this one. The Appraisal Institute of Canada’s professional standards address analysis, assumptions and limitations in valuation work, including the use of automated models. The underlying lesson for a homeowner is straightforward: examine the evidence behind the conclusion.
Give the estimate a five-question check
| Ask | What to look for |
|---|---|
| Is it the right property? | Check the address, property type and basic physical details. |
| What date does it represent? | Distinguish the valuation date from the date you opened the website. |
| Which homes support it? | Ask whether the comparison sales match the location, size, servicing and condition. |
| What information is uncertain? | Identify missing records or features that need an in-person review. |
| What decision am I making? | A listing plan, a lending decision and a net-proceeds budget are different tasks. |
Do not average away the questions
Suppose two websites give noticeably different answers. Taking their average feels like a compromise, but it does not establish that either input is sound. First compare the property details and dates. Then ask which sales are relevant and what differences need explaining.
In Greater Sudbury, your comparison should reflect the home you actually own. A house with private services should not be treated as interchangeable with a municipally serviced property simply because their bedroom counts match. The same applies to substantial differences in lot, layout and condition. Those differences call for investigation, not an automatic adjustment guessed from a photograph.
Use the right support for the job
For a possible sale, ask for a reasoned market analysis and a discussion of the competition buyers can choose from. If you need an appraisal for a particular financial or legal purpose, confirm the requirements with the recipient and a qualified appraiser. A marketing discussion is not a substitute for a report the lender or lawyer specifically requires. The AIC’s homeowner resources explain how an appraisal can support property decisions.
Keep the sale-price estimate separate from your moving budget. Mortgage payout, selling expenses and the next purchase affect the money available for your move. Do not spend an estimated gain before those numbers have been checked.
The next useful step
Save the estimate and its date, write down the details you want checked, and bring both to a pricing conversation. You do not need to defend the number. You need to understand it.
