When buying, how to discount NPN/Lien offers and then justify?

[Cameron Elliott]

Hello,

I am new to NPN buying, and am wondering if any old hands want to share their know-how.

I am going to be buying rights for liens for debts that are not current, and could need forclosure to recover.

I am curious how others set the discount price they offer on a NPN or lien from the full value of the debt,all fees & interest?

I am also curious how experienced pros justify their discount figure, ie, how do experienced NPN/lien buyers justify their offer. Is it something along the lines of: "Sometimes it takes years from the time of a foreclosure filing to remove an occupant, sell, and recover funds. And in some cases the expenses for legal fees can be double or treble the original judgement amount by the time the debt is recovered."

Any thoughts on doing this well are appreciated.
