Hi there! I've seen many Craigslist scams. Normally I see someone who takes a home that is listed for sale and use the pictures taken by the sales agent, and posted on Craigslist as a rental. So you would find the house on Craigslist as "for rent" but on trulia, zillow, ri living as "for sale".
Often times when you inquire about a scam property, you receive an email response by someone who claims to be out of town and sends you a legitimate looking application for apartment rental. Many times they claim that they are in another country doing some heart warming charity type of work. They also Telly you that since they cannot yet meet you in person, to go ahead and drive by.. Look in the windows.. Etc.
How to avoid getting scammed? Never send money to your supposed new landlord. Make sure the owner or property manager meets you at the property, has the keys to the space, and lets you in to see in person.
I hope this helps! Happy hunting!
