An appraisal is one qualified professional’s supported estimate of that value, produced for a specific purpose — usually a lender’s security. The two disagree most often at the top of the market for one structural reason: the appraiser is working from the same tiny set of comparable sales you are, and is required to support a conclusion with evidence rather than with conviction.
With roughly 300 GTA sales above $3 million across four months of 2026, an appraiser may have two or three usable comparables. If your price was set by competition rather than by evidence, the appraisal can land below it. That gap becomes your problem, because a lender advances against the appraised value, not the contract price.
Two different questions
| Market value | Appraised value | |
|---|---|---|
| Who decides | A buyer and a seller | A qualified appraiser |
| Based on | What someone will actually pay | Evidence the appraiser can support |
| Purpose | A transaction | Usually a lender’s security |
| Effect of competition | Can push it up substantially | Cannot be relied on as support |
| Effect of thin comparables | Widens the plausible range | Pulls the conclusion toward the evidence |
Neither is wrong. They are answering different questions, and the gap between them is largest exactly where the data is thinnest.
Why the gap opens above $3 million
Three hundred GTA sales above $3 million across four months. In one neighbourhood in one price band, an appraiser may find two or three usable comparables, none of them a close match. Every adjustment they make — for lot size, for age, for quality, for time — introduces judgement, and the discipline requires that judgement be supportable.
Now add competition. If a property attracted two determined buyers and closed $1.5 million over asking — as the Forest Hill house that sold in August 2026 did, at $23.5 million against a $22 million list — the price reflects a bidding outcome. An appraiser cannot use “two people wanted it badly” as evidence.
What actually reduces the risk
Establish the range before you offer
Work out what an appraiser is likely to be able to support, using the same three-part approach a good valuation uses: land value, depreciated replacement cost, and the short list of true comparables. If your intended price sits well above that range, know it before you sign, not after.
Keep a financing condition where you can
Competition sometimes makes this impossible. Where it is possible, it is the cleanest protection available.
Hold more liquidity than the minimum
The practical answer to appraisal risk at this level is cash on hand. If you are stretching to the exact down payment, an appraisal gap becomes a crisis rather than an inconvenience.
Give the appraiser something to work with
Appraisers are not adversaries. Documentation genuinely helps: the survey, permits, dates and scope of renovations, mechanical ages, and comparable sales that support the value including ones that may not surface in a routine search.
Where sellers should pay attention
If your buyer is financing, an appraisal gap can kill or delay your closing even after a firm agreement. Two things help. First, price against evidence, so that an appraiser can support your number. Second, prepare the documentation package before you list — the same survey, permit and mechanical documentation that reassures a buyer also supports the appraisal.
The practical takeaway
Assume the appraisal will be conservative and plan for it. At the top of the Toronto market, evidence is scarce and appraisers are required to rely on it. The buyers who get into trouble are not the ones who paid a strong price; they are the ones who paid a strong price with no financing condition and no spare liquidity.
Frequently asked questions
What happens if the appraisal comes in below my purchase price?
The lender advances against the lower of the appraised value and the purchase price, so the shortfall has to be covered from your own funds. On a firm offer with no financing condition, you are still bound to complete. This is the single most common financing problem in high-value Ontario purchases.
Why would an appraiser disagree with the market?
Because an appraisal must be supported by evidence. If a price was set by two determined buyers competing on a property with no close comparables, the appraiser has no data to support that number and will conclude at what the evidence carries.
How do I reduce appraisal risk?
Establish the likely appraised range before you write the offer rather than after, keep a financing condition where competition allows it, hold more liquidity than the minimum down payment requires, and give the appraiser the documentation that supports value — survey, permits, mechanical ages, renovation scope and dates.
Do lenders appraise every luxury property?
Where there is financing, effectively yes, and scrutiny increases with value and with how unusual the property is. Cash purchases have no appraisal requirement, which is one reason cash offers are treated as lower risk by sellers.
Is an appraisal the same as a home inspection?
No. An appraisal estimates value. An inspection assesses condition. They answer different questions and neither substitutes for the other.
Can I challenge an appraisal?
You can provide additional information — comparable sales the appraiser may not have considered, corrected square footage, documentation of recent work — through the appropriate channel with your lender. Whether it changes the conclusion is up to the appraiser.
