I have not yet heard of a 2nd lien holder selling their lien to a 3rd party, because who would buy it? The 2nd lien holder's paper in a SS is essentially useless/worth very little. Being 2nd lien position means that any overage after the 1st lien is satisfied, might go to you. In a SS, there is little chance of the 1st lien being satisfied, so why would someone buy the 2nd lien position paper that likely has no ROI? Doesn't sound very smart.
