That's still an awful idea. He just told you why he can't do a lump payment. That right there should be a red flag. He will choose his family over paying you if he has to. I'm sorry but that's a bad deal all around, unless you go into it knowing there could be a possibility that he may never pay you in full. I'm not saying you are flakey matt, I'm just saying worst case that's what would happen. Lol thats what I would do if it came down to it.
