Can you spot the real ones?

A friend of mine put this on her blog awhile ago and I thought it was a cool idea, so I asked her if it would be okay if I copied her. She said...Of Course! So, here it is -

Below are pictures of houses - some are real houses that actually exist and some are fake pictures. Your job is to look at them and decide which ones are real and which ones are not. Post your answers in the comment section. In a few days, I will post the answers! Good Luck!
