I provided an unsecured loan to a inc. Company (and former client who is the CEO) that is now overdue. A large capital repayment will be missed.

He brought on new investors to refinance his company. These new investors are conducting due diligence and expected to agree to terms soon. I am told by the new investors, that there is a list of other creditors and that my loan will be "considered" after their review.

The new investor's nebulous statement does not provide me with any comfort. And now the CEO, and my former client, seems to be MIA behind the new investors. Which specific questions should I ask these new investors to size up the situation?

No new questions, you should be demanding payment, explain that a law suit will be forth coming very quickly if they do not pay.
