I knew a couple that almost fell for this scam, but fortunately they were not that dumb. Report it to the FTC and he should contact Craigslist to have the ad pulled asap.

In this case the guy was brazen enough to meet them there (a lake house with no close neighbors) and show them around, but said they couldn't go in as the tenant hadn't moved out yet. He then asked for a deposit. The local police did get involved and it turns out the owners of the house were out of the country for a month.
