Is there a way for the loan to be closed in the name of his company? If not, this still may be doable given he's a doctor. Most any lender will know he has cash flow, he's got great credit, and more than likely plenty of assets.
Is this a purchase? If so, how much is the doctor putting down? Knowing the location helps as a lot of hard money lenders stick to their back yard.
I will say that 7% is probably not going to happen. 9% is more realistic in this market (it is hard money after all).
