If this property is on Craigslist listed as a rental for a better than average price and they are "promising" to send you the keys or some other crap. Think of it as a scam. Get a hold of a local Realtor to have them check the listing. DO NOT believe all Craigslist ads. IF you do wish to continue to check it out. Then get the information of who the owner(s) is supposed to be and if you meet the person face to face, ask for their ID (not a business card) and make sure that it's the same person as what the county records show. If there is any tap dancing, get out of there.
