Having personally been a victim of such a scam and done research within the RE industry and outside municipal contacts, the primary targets appear to be homes that appear to be or are advertised as vacant and as mentioned below are listed with RE agencies. These jokesters copy the company pics and description and count on the listing agents to be too busy with selling homes than renting (as small ROI) to notice. . . . joke is on them, we are noticing!
Having said that, I'd offer you the following advice whether you give craigslist a try or list with a RE company.
(1) Do not publish the actual address and/or advise the agency that you do not want the address to be included in any advertisements (except the local MLS).
(2) Do not state that the property is vacant and/or advise the agency.
(3) If the property is in fact vacant, do not publish pics of the interior (if it is not furnished).
In closing, I'll share another success story . . . just this past May a fellow agent had multiple rentals that "just weren't moving." On a Thursday, she placed ads on Craigslist . . . by Saturday, she filled the vacanies in 3 of 4 properties with people that contact her through those ads.
Unfortunately, Nigerian scams are all to common and advisements against them have been plentiful for many years.
Love and Peace,
