I'll add a few more things that can have a huge financial impact: required reserves, LTC (loan to cost), application or other upfront fees, and prepayment penalties.As a fellow flipper, I think it's important to have reserves, but they shouldn't be required as part of your funding.

The requirement to do this generally involves an experienced GC signing on the borrowing entity as a 20+% owner thus making them a signatory on the loan and responsible for the debt which in most cases is not very easy to find.
