Recently bought an off the plan property, I paid the deposit (bank cheque). I request a receipt from the agent for my record, the agent just email me and put in writing that she acknowledge the recepient of the deposit. The email was sent from a gmail account, no ABN. Only my property detail and also the amount. Just a bit worry as it looks doggy and not professional. What can I do to protect myself? I just want to make sure everything goes well. Thanks for any advice.
