Right now, I'm leaning towards the fact that Sherlock is his own father.
It's his house, his money, he hired Joan, and he fired Joan.
I think the most recent episode with Holmes' drug dealer makes the "Holmes' father doesn't exist and is actually Holmes himself" theory, which I myself held for a long time, not possible -- Holmes called his father and got the 2.2 million that Rhys needed to pay off the Dominican cartel. If Holmes had the money himself, he wouldn't have needed to make that phone call.
