Purchasing a note in Ch. 13 bankruptcy

[Anh N.]

Hi,

I'm looking into purchasing a second lien note where the borrower is in Ch. 13 bankruptcy.  There's $80K in arrears and $100K principal owed. The seller of the note is asking for $85K.  Under Ch. 13, the borrower will pay back the $80K arrears over 5 years.  I start getting payment on the $100K principal and interest after the five years.  Is this a good buy?  It seems like I'll be making zero interest in the first 5 years which doesn't seem like a good strategy.  Any feedback would be appreciated.  Thanks!
