Can somebody review these deals?

[Napoleon Jones]

A friend of mine who is a real estate invest is offered me a couple of properties he has found. These are all to be held as rentals, but I am just not able to see how they would turn any profit at all. They all seem to be losing over $100 a month using the Rent/2 - PI Mortgage formula. He sees them as money making deals so I just that any other investor would jump on. I just wanted to see what you guys here think. Thanks in advance, reading posts on here has been very informational.
