Assignment fee paid outside of closing?

[Carlyn Dodson]

Anyone wholesaling in Colorado, can you tell me what you know? I was recently asked if an assignment fee can be paid outside of a closing, where as the contract assignment would show assignment fee of $0,  but a separate contract between wholesaler and buyer existed on the side labeled a "finder's fee". What's the law on that? and is there a benefit to the buyer tax-wise if it is legal? I don't know anyone who has done a deal this way, and was caught off guard when asked.
