Whether you need to have a pre-prepared contract of sale before listing, simply depends on your state.
NSW and ACT sellers are required by law to have a contract of sale ready, prior to listing.
SA sellers will have to have the section 32 form filled out prior to listing also.
It's a great idea for sellers in any state to be as prepared as possible for a potential sale. We recommend having a solicitor/conveyancer ready and where able, pre-prepared forms. Please feel free to speak to our staff if you're unsure on what process is required for your state.
