Splitting a Mortgage with a friend

Does anyone have experience with this?

I've been told by multiple people that it's a very bad idea, but at the same time it's a buyer's market in Atlanta right now and although I have some savings I don't have quite enough to feel comfortable buying alone.

My good friend and I have talked about it a lot, we both have our reservations and are leaning towards not, but I wanted to get reddit's opinion as well.
