Was this a "fake" email response from craigslist regarding an apartment?

I’m really confused on this one. I recently posted an ad on craigslist for “apartment wanted”. A couple days ago I received an email regarding my post. The woman said she seen my post and thinks she can help. She told me she has an apartment for rent (which later turned out to be a house), in my area, for only $400. The first email sounded legitimate except for the fact that she mentioned she has relocated to Nigeria with her husband for some church thing which she put in bold letters, almost as if she were promoting the church…I asked for more information because it seemed too good to be true. She responded with an address and pictures. I put the address in my gps and the exact house number doesn’t exist. The street does but not the number. The pics she attached were very nice. There’s no way she’s renting it for $400. Not possible. So is this a scam of some sort? What is this person gaining out of this? Will they eventually try to get money from me? Are they promoting their religious beliefs? I’m confused! Why waste my time if you don’t really have an apartment for rent?!
