I would add, when mixing money and friends/family is unavoidable absolutely insist on a well worded contract. I know many people think that this is some sort of taboo among people you are close to, but it is essential all parties are very clear about what to expect from one another once money enters the picture.

It doesn't guarantee a trouble free time, but it at least avoids the tragic and very common "miscommunications".
