Given that you are "waiting for the other shoe to drop" I would encourage you to refrain from a Cash Out Refi.Opening a HELOC, on the other hand, can't hurt, because you don't have to use it, and once you open it it's available for a period of time should another investment opportunity arise.

Thanks Kevin, appreciate the encouragement.

I would encourage your buddy to do the same. 

This will encourage them to sign for the certified mail.
