What To Do With Closed Files?

[Bill B.]

Hi!

I am very close to closing my third NPN note file.

So far, all have been profitable.  (Thanks to God, my mentors, and BP!!)

The immediate question I have is, what do I do with closed files?  I'm planning to keep them for tax purposes, but are there any other legal requirements that compel me to hold onto files that are closed?

I'm thinking of having some of the mortgages "mounted".  Specifically, in a frame with matting. I may possibly include a plate at the bottom with facts about the file: 

Deal#: X,XXX

Purchased XX/XX/XXXX  

Exit: XX/XX/XXXX 

Annualized ROI: XX.XX%

Exit Type: XXXXXXXX 

Investor Return XX.XX%

I figure if big game hunters can mount their "kills", I can mount mine!!!  (Elmer Fudd voice: "SShhhhh!!! I'm hunting bad debt!!!")

Being as my home is not a public space, I don't believe I'd be making the information "public".

Thoughts?

Concerns?

Ideas?

Criticisms? 

Thanks to all!

Bill
