Every property valuation rests on a method. The method is how the valuer turns market evidence into an opinion of value, and choosing the right one is a large part of getting the figure right.
Most owners never see this step. But when a valuation report is used in a family law matter, a tax calculation or a dispute, the method is often the first thing a lawyer or accountant will examine.
For Sydney properties, which range from harbourside apartments to Western Sydney industrial sheds, the appropriate method depends on what the property is and how buyers in that market price it.
What is a property valuation method?
A valuation method is a recognised approach for estimating market value. Australian valuers work within professional standards and guidance, including those of the Australian Property Institute and the International Valuation Standards.
The aim of every method is the same: to reflect how a typical, informed buyer would assess the property on the valuation date. Different property types call for different approaches.
The main valuation methods
Direct comparison
The most common method for houses, units and vacant land. The valuer analyses recent sales of similar properties and adjusts for differences in land size, building, condition, location and features.
In Sydney, this method works best where good evidence exists, such as a typical house in Castle Hill or a unit in a large Rhodes complex.
Summation
The summation approach adds the value of the land to the depreciated value of the improvements. It is often used as a check on direct comparison, or for properties with few comparable sales, such as a large rural-residential holding near Richmond or Camden.
Capitalisation ofincome
Used for income-producing property, such as shops, offices and industrial units. The valuer converts the net rental income into a capital value using a yield taken from comparable investment sales.
This is common for commercial property in the Sydney CBD, North Sydney, Parramatta and industrial precincts around Wetherill Park and Smeaton Grange.
Hypothetical development(residual)
Where land has redevelopment potential, the valuer estimates the value of the completed project, then deducts costs, risk and profit to arrive at the land value. It may apply to sites with uplift potential around new Metro stations or rezoned precincts.
Discounted cash flow
Used mainly for larger commercial assets. The valuer projects income and expenses over a holding period and discounts them back to a present value.
What makes a method accurate?
A method produces a reliable result when:
It matches how buyers in that market actually price the property
The evidence behind it is recent, relevant and properly analysed
Adjustments are explained and reasonable
Inputs such as rent, yield and building cost are supported by market data
A second method is used as a cross-check where appropriate
The property's zoning, condition and title have been correctly identified
A well-chosen method with poor evidence can still produce an unreliable figure. Both need to be right.
How a valuer chooses and checks the method
1.Identify the property and purpose
The valuer confirms what is being valued, the interest being valued, the valuation date and why the report is needed.
2. Determine how the market prices it
Owner-occupied homes are usually priced by comparison. Investment property is often priced on income and yield.
3. Gather and analyse evidence
The valuer researches sales, leases and costs relevant to the chosen method.
4. Apply a primary method
The main method produces the core opinion of value.
5. Cross-check and reconcile
Where suitable, a second method tests the result. Any difference is examined and explained in the report.

Example: a shop-top property in Marrickville
Consider a two-storey building in Marrickville with a leased shop below and a residence above. A buyer might be an investor looking at income, or an owner-occupier planning to live upstairs.
A valuer may apply the capitalisation method to the shop income and direct comparison against similar shop-top sales, then reconcile the two. Planning controls under the Inner West Local Environmental Plan, heritage constraints and the lease terms would all be considered.
How two methods are reconciled
When a valuer uses two methods, the results rarely match exactly. Reconciliation is the step where the valuer weighs them and settles on a single figure.
Take the Marrickville shop-top example above as a simple illustration. Suppose, hypothetically, the capitalisation approach points to around $1.9 million and direct comparison with other shop-top sales points to around $2.05 million. The valuer would not simply average the two. Instead, they would ask which approach better reflects the likely buyer. If most similar buildings in the area are bought by investors, more weight may go to the income approach. If owner-occupiers are active, comparison evidence may carry more weight. The report should explain that reasoning.
What happens when the wrong method is used
Choosing an unsuitable method is one of the most common reasons a valuation is challenged. The figure may be arithmetically correct and still fail to reflect how the market would actually price the property.
Some examples of a poor fit in Sydney include:
Valuing a leased warehouse only by direct comparison. If the comparable sales were owner-occupied buildings, the valuation may ignore the lease term, rent level and tenant quality that an investor would focus on.
Valuing a development site as an ordinary house. A large block near a new Metro station may be worth more to a developer than to a family. Using only house sales may understate the land.
Relying on summation for a typical suburban home. Building cost does not always equal market value. A home that cost a great deal to build may not sell for that amount if buyers in the area will not pay for it.
Applying a yield from the wrong market. A capitalisation rate taken from CBD office sales will not suit a neighbourhood shop in Western Sydney.
A well-prepared report explains why the chosen method suits the property, which makes it far easier for solicitors, accountants or the ATO to accept the conclusion.
Information that helps the valuer apply the method
The documents a valuer needs depend on the method. Useful material often includes:
For direct comparison: building approvals, renovation invoices, floor plans andcphotographs that show the property's condition and features
For capitalisation: current leases, rent rolls, outgoings statements and details of any rent reviews, incentives or vacancies
For hypothetical development: planning certificates, any development applications or approvals, site surveys and relevant planning proposals
For summation: building contracts, construction dates and details of any significant improvements
For strata property: strata levy notices, by-laws and recent strata reports
Supplying the right information at the start helps the valuer test the method properly and usually shortens the time needed to complete the report.
Frequently asked questions
Which valuation method is most common for Sydney homes?
Direct comparison. Most houses and units are valued by analysing recent comparable sales and adjusting for differences.
Why would a valuer use more than one method?
A second method acts as a check. If the results differ significantly, the valuer investigates why before settling on a figure.
Is the method shown in the valuation report?
Yes. A formal report should state the method used, the evidence relied on and how the valuer reached the final figure.
How are commercial properties in Sydney usually valued?
Often by capitalisation of income, supported by direct comparison. Larger assets may also use discounted cash flow. See our commercial and industrial valuations page.
Can I choose which valuation method is used?
You can tell the valuer what the report is for and provide relevant information, but the choice of method is part of the valuer's professional judgement. The valuer should select the method that best reflects how the market prices the property and explain that choice in the report.
Does the method change for a retrospective valuation?
The methods are the same, but the evidence must come from the market around the historical valuation date.
