This sure does sound like a scam. When we were listing our house on Craigslist, someone hijacked our ad in much the same way. Fortunately for us, our personal phone number was listed in the body of the ad (which hijackers had obviously copy/pasted), so people were calling us directly asking about our home for rent. We had it listed for $3800, scammers had it listed for $1000. After the 3rd person called asking about our 4500sq ft home for $1000 rent (really? if it's too good to be true, it's probably a scam), I did a search on $1000 homes for rent, and there it was: our own ad! Apparently, according to a number of the potential victims who called us directly, the scammers were saying they were missionaries who were being called back to West Africa and wanted God-fearing folk to rent their home. They required a $600 deposit before they would send the key. I guess the scammers didn't check our ad carefully, though, because our location and phone number was listed so it was easy enough for people to drive by and check out our house (it was obviously not vacant, we were still living there!) or call us directly. One couple who walked up to our front door told us that "as soon as we drove up, we realized there was no way THIS house was going for only $1000". If you're renting a house through Craigslist, absolutely insist on seeing the house personally before signing anything or writing any checks. If the landlord refuses to show you the house, it's a scam.
