Make clear to yourself, what you are looking for and what your budget is.
Often times it is really helpful, to write down, what you want and don’t want. You can split it up into four categories for example: Must have (e.g. ocean view); Would be nice (e.g. granny flat); do not need it (e.g. pool); do not want it (e.g. huge garden)
On online portals like realestate.com.au, you can now search for your preferences (for example: ocean view) and indicate your price range. It is also helpful to talk to different brokers and tell them, what you are looking for.
Actions you might want to take
In case, you need a loan to purchase a property, it is often times helpful to speak to your bank or to your mortgage broker first, in order to get a feeling for, on how much they would lend you to purchase a property (watch video with mortgage broker)
In case you have pets and you want to purchase a unit in a complex for example, you should always check if there are certain rules.
Information to exchange
If you are really interested in a property, the agency can send you the sales contract for the property and you can make an offer on the property in the next step.
