Its defiantly a good idea to do as much due diligence as you can on the seller if you are looking at doing a partial or a note fund.If it goes non-performing you need to make sure you can trust the person who will be responsible for getting the note re-performing and you need to understand the contract so you understand how the event of a non-performer should play out.I would definitely put Chris in the upper echelon of note investors based on my research and experience.

We will see how it plays out.
