Short answer
Market value is the estimated amount for which a property would exchange at the valuation date between a willing buyer and a willing seller in an arm’s length transaction, after proper marketing, where both parties act knowledgeably, prudently and without compulsion.
It is not automatically the same as the contract price, an agent appraisal, an online estimate, the ACT unimproved value / UCV, a mortgage-security assessment, or the amount an owner expects to receive.
Why this matters
Market value is the foundation of most formal property valuation work.
It is commonly relevant to Family Law property settlements, Capital Gains Tax, Stamp Duty, deceased estates, SMSF reporting, pre-sale advice and general market value assessments.
The same property can require different valuation analysis depending on the purpose of the report and the relevant valuation date. A current valuation for pre-sale advice is different from a retrospective valuation prepared as at a past date for CGT or Family Law purposes.
How a valuer considers market value
A valuer does not simply ask what the owner wants, what an agent hopes to achieve, or what an online estimate suggests.
A proper market value assessment considers how the market would likely respond to the property as at the valuation date.
This includes consideration of:
- The property location
- Land size and site characteristics
- Building size, age, condition and layout
- Accommodation and car parking
- Planning controls and permitted use
- Comparable sales evidence
- Market conditions at the valuation date
- Any assumptions or limitations applying to the instruction
Comparable sales are central to the process, but market value is not a simple average of sale prices. Each sale needs to be considered for comparability, including location, land size, improvements, condition, sale date and sale circumstances.
Common misunderstandings
Market value is not the same as an agent appraisal.
An agent appraisal is usually prepared for selling or listing purposes. It may be helpful market commentary, but it is not the same as an independent valuation report prepared for a stated purpose, valuation date and intended user.
Market value is not always the contract price.
A contract price may be strong evidence, but it still needs to be considered in context. The transaction may be affected by related-party dealings, limited marketing, urgency, special purchaser interest, unusual terms or other non-market factors.
Market value is not the same as unimproved value.
In the ACT, unimproved value / UCV is a statutory land value used for government rating, land tax and related charging purposes. It is not the same as the market value of an improved residential property.
Market value is not a guaranteed sale price.
A valuation is an opinion formed from evidence and professional judgement at a specific date. The actual sale price may differ because market conditions, buyer behaviour, presentation, marketing and negotiation can all influence the final result.
When a formal valuation may be relevant
A formal market valuation may be requested where the value needs to be relied upon for a legal, taxation, revenue, accounting or dispute resolution purpose.
Common examples include:
- Family Law property settlement
- Capital Gains Tax reporting
- Stamp Duty or transfer duty
- Deceased estate administration
- SMSF reporting
- Related-party transfers
- Pre-sale assessment where independent advice is required
The relevant purpose should be clear before the valuation is prepared, because the report format, valuation date, evidence and assumptions may differ.
