similar story on gumtree rental scam, insist to make the payment in advance:

Email as below:
Thank you for replying to me. My name is Zhu Lan, 39 years old, a single and non-smoker lady. I am willing to rent the room. I am at sea at the moment as i work on a cruise ship as a Chef.

I will be living and working down there as my contract here is coming to an end that's why I am coming there. But due to the nature of my work of having a busy schedule, phone calls making and visiting of website are restricted, I only squeezed out time to check this advert and send you a message so I won't be able to come for the viewing myself.

I will like you to kindly calculate the total cost covering my first six months rent together with deposit and I will be staying for long as your room is available.

Please kindly get back to me with some pictures of the room and your address for me to forward it to my mover agent to calculate the total cost of moving my stuffs over there. I have attached my IC with this email for you to have a view of me. Looking forward to read back from you soon so I can provide you with my WhatsApp number
