It’s not only note investing but I see a lot of posts on here and some of my favorites are:1. what book should I read to buy a 100 unit apartment building” when they have never been a landlord 2. how do I subdivide and develop a parcel of land and how much should I budget when they have never owned anything. 3.what should I do with my $100k. 4.

Everyone has their favorites.

@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. 

As I live in Hot Springs my favorites are the RE Investors meetup on the 3rd Sat. of the month and the Landlord meeting on the 3rd Thurs. of the month.
