  • Go to any Australian property portal website that listed properties for sale and sold. The most popular is: realestate⭷ and domain⭷).

  • Look for your suburb of interest (note: some websites by default has the "surrounding suburbs" option is on, so deselect that.

  • Go to their "sold" section, not "for sale" section.

  • Filter the options by choosing a similar attribute to your property (property type, number of bedrooms, land size, etc).

  • Sort the property list based on the newest sold date to the oldest (note: some websites by default sort the list based on most relevant).

  • Now you have comparable data of recently sold property in your suburb based on sales date.

When you do your research try to look for these characteristics:

  • The property sold within the last three to six months, the more recent the better.

Step 2: Get a list of sold properties that are comparable with yours.

You need to make a list of recently sold properties that are closely similar to yours. Consider the following characteristics in particular:

  • Location: Compare the distance from local amenities and public transport? Are the property has the same school catchment?

  • Size: Does the land size comparable? Are the building size or living area comparable?

  • Features: Is the number of bedrooms, bathrooms and parking spaces the same? How about the pool?

  • Presentation: Are the properties have the same presentation or style?

  • Age: Is the age of the building comparable?

Step 3: Compare the sold prices of comparable properties to get your property value price.

To get an accurate figure, you must compare properties that are as closely similar to yours as possible.

Let's start with something relatively simple. Imagine you want to sell a unit in a large, high-rise apartment complex. Chances are some of the units have recently sold, and a few of the sold might have a similar floorplan to the floorplan of your unit. Together with other factors discussed above, this sold unit will be the based for your comparable properties. The more comparable sales you find, the greater your confidence level that you are close to market price.

Physically inspecting open homes of another unit for sale allows a better comparison because you can see for yourself any differences. When you have done your research and inspected enough property over some time, you will be able to assess the market condition and use this knowledge to determine the price of your property.

The same principle applies to the house, but you have to do more thorough research. You need to look at all houses similar to yours that come on the market in the same neighbourhood as yours and record the prices they are sold for. After a long period of research and exposure to the market, you would become an expert in pricing by seeing what other people were prepared to pay for each house. The longer you did this, the better you would become. This is the best knowledge you can obtain because it is unbiased and unfiltered by any third party.


In summary, to get the likely selling price of your property, you can do online research of the recently sold price properties similar to yours. The steps are:

  • Step 1: Look for comparable local sales data.

  • Step 2: Get a list of sold properties that are comparable with yours.

  • Step 3: Compare the sold prices of comparable properties to get your property value price.
