Are probate leads worth it?

[Sean Dezoysa]

Recently a wholesaler told me he doesn't like probates because they often come with liens. He says he prefers to wait until the liens are paid off instead of inheriting the mess.

I know probates also have issues arising from tracking down the Executor, and getting all family interests to be happy with the offer you present to him (though he has final authority). 

Does anyone think probate leads are worth it? If they are motivated I'd still think they're worth dealing with these types of issues. But I wanted to hear what active wholesalers thought.
