Sorry, maybe we're talking at crossed purposes.
I was assuming that any cash paid for CCFC would be nominal, the real negotiation happens around the repayment of the loan from SISU.
As I see it the only valid exit strategy for SISU and their investors is to negotiate the best deal possible on the debt. IIRC the original Hoffman offer was quite a poor one (repayment deferred until we went up and if that didn't happen in 3 years it was written off). SISU will want more than that, probably something up front and some more over time, maybe as well as clauses related to club performance.
Hoffman's group will want to pay as little of the debt as possible. The bigger that debt gets and the less CCFC are bringing in, the more twitchy SISU and their investors will get about never seeing any cash again and the more likely they are to accept a lower amount, or less preferential terms on the repayment.
That's what I mean by it being worth Hoffman's while to wait it out. The debt may be bigger at the end of the season, but chances are SISU will be more willing to write some of it off.
EDIT: Interesting you say SISU won't grow the loan. How are we paying the bills at the moment then? Surely it's in SISU's interests to be the sole creditor as then they are the only ones who can put the club into admin. Otherwise (as I understand it, please correct if wrong) some CCFC fan florist owed a tenner could call in admin with the express aim of forcing SISU out.
