Short answer
A property valuation is a formal assessment of market value prepared by a qualified valuer for a stated purpose, valuation date and intended use.
An agent appraisal is usually an estimate of likely selling price or price range, prepared by a real estate agent for marketing or selling purposes.
Both can be useful, but they are not the same thing.
Why the distinction matters
Many property owners first receive an agent appraisal because they are thinking about selling. That can be useful for understanding likely buyer interest and current market sentiment.
However, an agent appraisal is not usually prepared as independent valuation evidence. It may not be suitable for Family Law, Capital Gains Tax, Stamp Duty, deceased estate, SMSF or other formal purposes.
A formal valuation is prepared on a different basis. The valuer must consider the property, the instructions, the valuation purpose, the valuation date, the available market evidence and any relevant assumptions or limitations.
The difference matters because the report may later be relied upon by a solicitor, accountant, court, revenue authority, auditor, trustee or other professional adviser.
In the ACT, a formal valuation may also require consideration of lease purpose clauses, planning controls, unit title or strata attributes, government unimproved value / UCV, building approvals, energy efficiency, renovation standard and local market evidence.
What an agent appraisal usually does
An agent appraisal is commonly prepared to help an owner understand a likely selling range if the property were placed on the market.
It may consider recent sales, buyer enquiry, presentation, local competition and the agent’s experience in that suburb or property type.
An appraisal may also be influenced by the agent’s role in trying to win a listing, set a campaign strategy, or encourage the owner to test the market.
That does not mean the appraisal is wrong. It means its purpose is different.
What a formal valuation does
A formal valuation is prepared to provide an independent opinion of value as at a stated date.
The valuer considers the property’s location, land, zoning, legal attributes, accommodation, condition, improvements, market demand and comparable sales evidence.
The valuer then forms an opinion of market value having regard to the stated purpose of the report.
In the ACT, this may also require consideration of lease purpose clauses, planning controls, unit title or strata attributes, government unimproved value / UCV, building approvals, energy efficiency, renovation standard and local market evidence.
The valuation date is important
An agent appraisal usually reflects the agent’s view of the current selling environment.
A formal valuation may be current or retrospective.
For example, a Capital Gains Tax valuation may require a market value as at a past date. A deceased estate valuation may require a date of death assessment. A Family Law matter may require a valuation as at a date agreed by the parties or their lawyers.
In those situations, the current market is not the only issue. The valuer must analyse the evidence relevant to the required valuation date.
Independence and intended use
A formal valuation is prepared for a defined purpose and intended use. It should identify who can rely on the report and what the report is being prepared for.
An agent appraisal is generally not prepared with the same reliance framework. It is usually not intended to be relied upon as formal valuation evidence by a court, revenue authority, auditor or taxation adviser.
This is one of the main reasons an agent appraisal may not be enough where value has legal, taxation or financial consequences.
Common misunderstanding
A common misunderstanding is that a high agent appraisal proves the property is worth that amount.
It does not necessarily do so.
Likewise, a low agent appraisal does not automatically prove that market value is lower.
A valuer may agree with an agent’s view, partly agree with it, or form a different opinion after inspecting the property and analysing the sales evidence.
The issue is not whether the agent is experienced. The issue is whether the document is a formal valuation prepared for the correct purpose, valuation date and intended users.
When an agent appraisal may be enough
An agent appraisal may be enough where the owner is only seeking informal selling advice or wants to understand possible market interest before deciding whether to sell.
It may also be useful as general background information.
However, where the value will be relied upon for Family Law, Capital Gains Tax, Stamp Duty, deceased estate, SMSF, litigation, accounting or formal reporting purposes, a valuation prepared by a qualified valuer is usually more appropriate.
A formal valuation may be required where the value needs to be relied upon by another party or adviser.
When a formal valuation is required
Examples include:
- Family Law property settlement
- Capital Gains Tax reporting
- Stamp Duty or transfer duty matters
- Deceased estate administration
- SMSF reporting or audit requirements
- Related-party transfers
- Pre-sale advice where an independent value is required
- Disputes about value
- Professional or accounting records
In those cases, the valuation should be prepared for the correct purpose, valuation date and intended use.
When an agent appraisal may be enough
An agent appraisal may be sufficient where the owner is seeking informal selling advice, considering whether to list the property, or wanting to understand a possible sale campaign. It may also be useful as general market background. It should not be treated as a formal valuation report unless the issue only requires informal selling guidance.

Valuer’s note
In practice, agent appraisals and valuations are often confused because both discuss property value. The difference is not only the final number. The real difference is purpose, independence, evidence, valuation date and reliance. A document prepared to help sell a property is not the same as a valuation report prepared for a formal legal, taxation, accounting or reporting purpose.
Disclaimer
This information is general in nature and should not be relied upon as valuation, legal, taxation or financial advice. Every valuation depends on the specific property, purpose, valuation date, evidence and instructions. For a formal opinion of value, written instructions and a valuation report are required.
