I would probably ask to see pictures of his collection, if not view them in person. I'm sorry but if someone says they have multiple snakes but can't afford to pay a rehoming fee, I see an issue and I would not adopt out to them. You could probably just as easily find someone else to take the snake.
This is where I'm at. How can you not afford a new one, but expect me to believe you can properly care for her?
So, before anything happens I'll be getting some more information.
