Same industry deal structure

I am looking at a company in the same industry as our current company. Hoping for some advice on ways to structure. A few questions have come up.
(Pardon my ignorance.)

1. I heard a podcast recently of a holdco bringing in an operator to carry the SBA note. Seems like that operator would hold quite a bit of equity for that to happen. Doesn't that defeat the purpose of the holdco?

2. Could you go the subsidiary route with a majority stock purchase if the owner wants to stay involved?

3. If an outright asset purchase, could one partner of the parent company carry the SBA note for the acquisition?
