COJs are becoming increasingly common... YSC, Tyrian Bull, and many others are using them (typically on $10K+ deals). COJ sounds a little aggressive for the deal you are outlining though.

I haven't researched the actual value of a COJ from a funder's standpoint, but I would assume that it would allow you to sell non-performing MCA debt at a higher price? Does anyone have any COJ knowledge they would like to share (legally speaking).
