Assignment Fees

[Terry Royce]

I guess I am a bit confused on this assignment fee thing.
If I put a house under contract for 30k, and then assign it to my end buyer through an assignment contract for 39k, does my end buyer have to cut me a check for 9k right there, or does that amount get wrapped into the loan?

How do I get paid is the main question? It seems like that would be a large amount for many people to just pay upfront on the spot.

Thanks
