Selling a note to another buyer

[Horacio Gutierrez]

Hello,

Say I do some seller finance where I carry a note for $100000 for 30 years at 5%. I decide to sell the note in 10 years will as a seller need to sell the note at a discount and can loose money or even if a seller sells the note a discount he shouldnt looks his principal if he can how should he avoid this, would he have to lower interest and increase the payments before 5 years?
