17. The classic classified scam
If you see something, a car, a house, with a ridiculously low price, something that stands out, then really question whether it is genuine. This type of scam is extremely common. The house itself, or car etc, may be for sale, but not with the person you are dealing with – they have just stolen the photo. If you never get to see it yourself, and they request an up-front deposit, don’t pay a dime. It’s a con.
