Different Methods Of Property Valuation
7 Different Methods Of Property Valuation
Are you trying to understand how the value of a property is determined, whether for selling, buying, refinancing or investment purposes? Property valuation is a process used to estimate the market value of real estate based on several variables. Understanding the techniques involved can help property owners and investors make informed decisions—whether they’re in Brisbane, on the Sunshine Coast, or elsewhere in Queensland. In this blog, we’ll break down the seven commonly used
property valuation methods and explain how each one can be applied to different types of properties and situations.
1. Market Comparison Method
The Market Comparison Method—also known as the comparable sales method—is one of the most commonly used property valuation techniques in residential real estate. It works by comparing the property being assessed to other similar properties that have recently sold in the same or nearby locations.
When Is It Used?
This method is particularly relevant for houses, townhouses, and units where there is an active local market with recent sales data. It is used widely for both pre-purchase and pre-sale valuations.
How it works:
Valuers look at the sale price of similar properties and make adjustments based on factors such as:

- Location differences
- Size & layout
- Building condition
- Renovations or improvements
- Time of sale (market conditions at the time)
2. Income Capitalisation Method
The income capitalisation method is primarily used for commercial properties or residential investment properties that generate rental income. It bases the value of a property on the income it can produce, often applying a capitalisation rate (or “cap rate”) to determine its current worth.
When is it used?
This method is commonly applied to offices, retail spaces, apartment buildings, and industrial facilities. It may also be used for high-yield residential investments.
How it works:
- The property’s net income (after expenses) is calculated.
- A suitable capitalisation rate is selected based on market trends and comparable investment returns.
- The net income is divided by the cap rate to produce an estimate of value.
3. Summation Method
The summation method—also referred to as the cost approach—is based on the idea that a property’s value is equal to the value of the land plus the replacement cost of any buildings or improvements, less depreciation.
When is it used?
This method is often applied when there are limited comparable sales available. It’s commonly used for specialised properties such as rural dwellings, large estates, or properties with significant improvements like outbuildings or custom structures.
How it works:
- The land value is estimated using recent sales of similar vacant sites.
- The cost to replace any buildings or structures is calculated.
- Depreciation is subtracted to reflect wear and age.
4. Discounted Cash Flow (DCF) Method
The Discounted Cash Flow (DCF) Method is a forward-looking valuation approach used for properties with complex income streams. It projects the future income of a property over a specific period (typically 5–10 years) and discounts it back to present-day value using a chosen discount rate.
When is it used?
This technique is often used for large-scale commercial assets, developments, or properties where income may change significantly over time due to leases, vacancies, or operating costs.
How it works:
- Cash flows are projected year by year.
- A terminal value (final sale price) is estimated at the end of the projection.
- A discount rate is applied to all future cash flows and the terminal value.
5. Replacement Cost Method
The Replacement Cost Method values a property based on the cost of replacing the current structure with one of similar utility using modern construction techniques and materials, with less depreciation.
When is it used?
Often used for insurance valuations or when determining replacement cost for properties where market data is scarce or where uniqueness makes comparison difficult, such as public facilities, aged care properties or unique industrial buildings.
How it works:
- Determine the construction cost of a similar new structure.
- Apply depreciation based on age, wear, and obsolescence.
- Add the land value from recent sales of comparable vacant sites.
6. Residual Value Method
The Residual Value Method is often used in development feasibility studies. It estimates the value of land or property by deducting the total cost of development (including construction, fees, and margins) from the projected end sale value.
When is it used?
Typically applied in situations involving subdivisions, apartment buildings, or mixed-use developments.
How it works:
- Estimate the gross realisation value—what the completed development could sell for.
- Subtract all development and finance costs.
- The remainder is the residual land value—how much the development site is worth today.
7. Depreciated Replacement Cost (DRC) Method
The Depreciated Replacement Cost Method is a variation of the Replacement Cost Method used mainly for properties that are not bought and sold in the market. This includes public buildings like schools, community centres or infrastructure assets.
When is it used?
Most often in valuations for government reporting, or where the asset is unique and not income-producing.
How it works:
- Determine the cost to replace the asset.
- Deduct depreciation based on age, condition, and functional life.
- Consider land value separately if applicable.
Why Different Valuation Methods Are Used
The method chosen depends largely on the type of property, its use, available data, and the purpose of the valuation. For example:
- A homeowner seeking to refinance might receive a Market Comparison valuation.
- A property developer may require a residual value analysis.
- An investor might ask for both a market comparison and an income capitalisation assessment for a more complete picture.

Valuers often apply more than one method and reconcile the results to arrive at a final figure that reflects both market evidence and valuation theory.
