Where did you find this listing? What is the property address? It has been my experience that many rentals that are posted on craigslist.com with low rents, requiring you to e-mail the owner who is out of the country, and then get a response that his wife or someone will meet you at the property, then they ask you to send cashiers checks out of the country are scams. Go with your gut...if it appears to you to be fraudulent, then it probably is!
Your best bet is to speak with a Realtor to help you find a rental property. Feel free to contact me directly if I may be of service.
All the best,
