Selling Note, swapping the lienholder on property status???

[Ty Ottaberry]

so I'm selling one of my owner financing notes to another BP member.   What needs to be done to update the property status showing that he's the new lienholder.   Dose the tenant need to be apart of the deal ? None of the turms are changing on the note he is just simply buying me out at fair price 

I'm sure there is a few note buyers out there that could shed some light on this situation
