How to sell a note/lease purchase option?

[Jacob Price]

I have an odd lease-purchase option that the courts have effectively deemed a note. It has about $60k left on the equity, it's 100k house, and is accruing 6.875% interest. It's not clearly written as a note, but nonetheless when going for an eviction they decided that the tenant had equity. 

I'm not the first lien as I had seller financing on it when I bought it in a package, only owe 20k, so I'm curious if anyone has any insight into this type of situation. Is this something I could sell or am I stuck with it for another 16 years.
