What Is a Home Appraisal?
A home appraisal is an independent, certified opinion of a property's fair market value on a specific date, prepared by a professional appraiser. In Canada it is completed to recognized professional standards (CUSPAP) and relied on by lenders, lawyers, accountants, and homeowners who need a defensible value, not just an estimate.

The short version
What a home appraisal actually is
An appraisal answers a sharper question than "what might this home be worth?" It asks what the most supportable market value is for this exact property, on a specific date, for a specific purpose. That focus is what makes it useful in mortgage underwriting, refinancing, estate work, and separation files.
It is also why an appraisal is not the same as a sale price. Buyers and sellers agree on numbers for many reasons. An appraisal steps back and tests value against comparable sales, property characteristics, and current market evidence.
On-site context
Value starts here.
Why a current value matters right now
In a softening market, a value from months ago can age badly, which is exactly why a value tied to a specific date beats a stale estimate. In 2026 Canada's banking regulator (OSFI) warned lenders that valuing some condos at an older date rather than at closing can leave loans under-collateralized when prices fall, and national benchmark prices have continued to soften. A current, assignment-specific appraisal helps you avoid acting on an outdated number.
Appraisal vs CMA vs online estimate
Three kinds of "home value," three different jobs
A professional appraisal, a realtor's pricing opinion (CMA), and an online estimate can all be useful, but they are not interchangeable. An appraisal is the document you reach for when the value has to stand up to scrutiny.
| Home appraisal | Realtor CMA | Online estimate | |
|---|---|---|---|
| Prepared by | Designated independent appraiser (CRA / AIC) | Real estate agent | Algorithm |
| Based on | Inspection + verified comparables + analysis | Recent comparable listings and sales | Public data, no inspection |
| Independent of the deal | Yes | Has a role in the transaction | n/a |
| Written standards | CUSPAP-compliant report | None required | None |
| Relied on for financing, legal, tax files | Yes | Generally no | No |
How it works
How a home appraisal works
The process is methodical, not a quick walk-through and a guess. For the full step-by-step version, see our complete home appraisal guide.
Confirm the assignment
We confirm the property, the intended use, and the effective date the value applies to.
Inspect the property
An on-site review of accessible areas, improvements, condition, layout, and mechanical spaces.
Gather the evidence
Recent comparable sales and current market data for the area are collected and verified.
Analyze and reconcile
We weigh location, condition, and comparables, led by the Direct Comparison Approach.
Deliver the report
A written, CUSPAP-compliant report with a supported opinion of value.
Inspection evidence
Condition tells the story.
From the appraiser
What I look at first when I walk in
When I walk into a home, I first look at it the way the market will. Before the cosmetic finishes, I pay attention to the street, the lot, parking, exterior condition, the layout, and whether the property is typical for the neighbourhood. Inside, I focus on the condition and quality of improvements, basement use, and mechanical areas. I am asking a market question: compared with similar homes that recently sold, would a typical buyer pay more, less, or about the same?
Location and lot
The street, the lot, parking, and whether the property is typical for the neighbourhood.
Size and layout
Usable space and a functional layout, which buyers reward more than owners expect.
Condition and quality
The condition and quality of improvements, basement use, and mechanical areas.
Comparable sales
Recent sales of similar nearby homes, reconciled against the subject property.
Common blind spots
What homeowners overvalue, and what they miss
Often over-valued
Upgrades that were expensive or personal but do not transfer dollar-for-dollar: a custom feature wall, luxury fixtures, or a very specific renovation style. The market may give only partial recognition if buyers there mainly pay for location, lot, layout, parking, and condition.
Often under-valued
The practical things buyers and appraisers notice quickly: a workable layout, a clean maintenance history, usable basement space, good parking, and sound mechanical systems. A well-maintained home with a strong layout can compete better than one with expensive finishes but functional problems.
What surprises people
The value is not what you spent, or hoped
An appraisal is not based on what the owner spent, what a neighbour is asking, or what the owner hopes the property is worth. It is a supported opinion of value as of a specific effective date, built from the property's characteristics, location, market conditions, and comparable sales. In most residential assignments the Direct Comparison Approach carries the most weight.
Illustrative example
Consider a newer York Region single-family home that transferred from the builder at about $1.13 million in 2022. By a 2026 effective date, the supported value was closer to $1.04 million. The home was not worse. The local market had softened from the post-pandemic peak, and the comparable sales on the effective date supported a lower value than the earlier purchase price. The effective date and the comparable evidence control the value, not the original cost.
When you need one
When you actually need a home appraisal
A simple rule: when the value could materially affect money, taxes, financing, or a dispute, an appraisal becomes more useful than a casual estimate. The appraiser provides the independent value opinion; your lawyer or accountant decides how it is used.
Cost and timing
How much it costs and how long it takes
Residential appraisal fees vary by property type, purpose, complexity, and turnaround. In 2026, many residential appraisal reports in Toronto, Mississauga, Etobicoke, and across the Greater Toronto Area fall around $900 to $2,500+ CAD, with complex, urgent, retrospective, high-value, or litigation-related properties costing more and taking longer. A standard report is usually ready about four to six business days after the inspection and required documents. For current pricing and what affects the fee, see our home appraisal cost guide.
Who performs it
Who can perform a home appraisal in Ontario
In Canada, residential appraisals are completed by designated members of the Appraisal Institute of Canada (AIC), most commonly a CRA (Canadian Residential Appraiser), working to CUSPAP professional standards (2026, effective April 1, 2026). A designated, independent appraiser produces a written report that lenders, lawyers, and accountants rely on, which is the practical difference between an appraisal and an estimate.
AIC designation
CRA members follow a formal professional designation path for residential valuation work.
CUSPAP standards
The report is written to Canadian Uniform Standards of Professional Appraisal Practice.
Independent opinion
The value is prepared for the assignment purpose, not to help a transaction hit a target.
Common questions
Home appraisal FAQ
Is a home appraisal the same as a home inspection?+
No. An appraisal is an opinion of market value; a home inspection assesses the property's physical condition and defects. Condition affects value, but the two reports answer different questions and are usually done by different professionals.
Who pays for a home appraisal?+
It depends on who orders it and why. In financing, the borrower typically pays even though the lender often receives the report. For estate, divorce, or tax work, the party who orders the appraisal usually pays. See our guide on who owns the appraisal report for the details.
How long is a home appraisal good for?+
An appraisal reflects market value as of a specific effective date, so it is most reliable close to that date. In a moving market its usefulness can fade within a few months, which is why timing matters for financing, tax, and legal files.
What happens if the appraisal comes in lower than the purchase price?+
Lenders generally base financing on the lower of the purchase price and the appraised value, so a lower appraisal can change the down payment or financing terms. It is one reason lenders treat the report as a risk document, not a marketing one.
Do I need an appraisal to refinance?+
Often, yes. Lenders frequently require a current value to confirm the property supports the new loan amount, especially when prices are shifting.
How accurate is a home appraisal?+
An appraisal is a supported professional opinion, not a guarantee, but it is built from a physical inspection plus verified comparable sales and market analysis, which makes it far more reliable than an automated online estimate, particularly for atypical homes.
