What Your Home Is Worth — and How an Estimate Is Actually Built
A home's value isn't a number a website pulls from the air — it's a judgment built from comparable sold homes, adjusted for what makes yours different, and it's only as good as the sales behind it.
The only evidence that really counts: sold homes
Asking prices are opinions. Sold prices are facts. When agents, appraisers and serious buyers value a home, they start with comparable sales — "comps" — homes similar to yours, in your area, that have actually sold, ideally recently. A comp earns its name by being genuinely comparable: same neighbourhood or as close as possible, similar size, lot, age, style and bedroom count. Three strong comps usually say more than ten weak ones. A detached home two streets over that sold last month outweighs a similar-looking house across town that sold last year, because markets move and locations differ street by street.
This is also why your home's value has a date attached to it. A valuation built on spring sales describes the spring market. In a fast-moving market, comps older than a few months are seasoning, not the main ingredient.
Adjustments: where the judgment lives
No comp is identical to your home, so the estimate gets adjusted. If a comp has a finished basement and yours doesn't, its price is adjusted downward to stand in for your home. If yours has an extra bathroom, a larger lot, or a renovated kitchen, adjustments run the other way. Appraisers and experienced agents make these adjustments line by line — square footage, bedrooms, bathrooms, parking, lot size, condition, updates — and each adjustment is a small, debatable judgment. That's why two competent professionals can value the same home somewhat differently without either being wrong: the comps may be identical, but the adjustments are human.
Condition is the adjustment buyers most often overestimate in their own favour. A home that shows well and has been maintained supports the top of its range; a home with a tired roof, original mechanicals and dated finishes does not, no matter how good the street is.
Asking prices still matter — differently
Sold comps say what your home was worth in the recent past. Active listings say what you're competing with right now. If three similar homes on nearby streets are sitting for sale, buyers will compare yours to them, and a valuation that ignores current competition will produce a list price the market politely ignores. Good estimates use both: sold data to establish value, live listings to establish strategy. When a home sits unsold, it's usually not the market being wrong — it's the price disagreeing with both sets of evidence at once.
Why online estimates disagree with each other (and with reality)
Automated estimates are built by algorithms working from whatever data they can get. In Ontario, that data has real gaps and quirks:
- Asking vs. sold data. Some tools lean heavily on listing prices, which reflect sellers' hopes, not outcomes.
- They can't see inside. An algorithm doesn't know about your renovated kitchen — or your mould problem. It values the statistical average of your home, not your home.
- Boundaries fool them. A model may blend sales from a much pricier pocket a few streets away, or miss that your street itself carries a premium.
- Thin data, wide swings. In areas with few recent sales, a single unusual transaction can drag an automated estimate far off course.
Treat any instant online number as a rough range-finder, not a valuation. If two tools give you wildly different figures, that's the data telling you the honest answer is a range — and that a human needs to look at the actual comps.
What a proper estimate looks like
A full estimate prepared by the HomesFound team is built the way an appraiser builds one: we pull comparable homes that have actually sold near yours, adjust for the differences that matter, cross-check against what's currently listed in competition, and give you a range with the reasoning attached — which comps were used, and why. If the evidence is thin, we say so rather than dressing up a guess. The number is a starting point for a pricing conversation, not a promise of what a buyer will pay; the market renders the final verdict on closing day.
A few honest caveats apply to every estimate, ours included:
- An estimate is not an appraisal, and a lender's appraiser may land elsewhere.
- Value and list price are different decisions — strategy can justify pricing above or below the estimated value.
- Estimates age. One prepared months ago should be refreshed against new sales.
Next step
Get an estimate built from real comparable sales rather than an algorithm's guess — request yours at the HomesFound home estimator. Once you have the range, the next decision is what to do with it: list low, list at market, or hold offers — and if the sale is from an estate, how probate changes the process.
