@Csilla Veress A couple of books that may help with understanding PV (present value) calculations, as well as note investing in general, are:Invest in Debt by Jimmy NapierPaper Profits by @Joshua Andrews  (my personal favorite)This blog post by @Mike Hartzog may also be helpful:https://www.biggerpockets.com/blogs/5359/41924-doi...PV is the way most note investors do pricing for performing notes, but for non-performing, you'll want to build an ROI calculator as  @Chris Seveney suggested so you can look at various exit scenarios and take into account costs like servicing, legal fees, insurance, etc.
