This is the elephant in the room for any sale of us. The logical thing for any buyer is to buy Drumaville from Short, which keeps the amount owed to them internal to the group (it would also allow them to capitalise that loan at no real loss to themselves). However, they would need to repay or refinance the loan from SBC by July 2019, and this effectively raises the asking price by whatever it is at the moment (it was £70m in July 2016, but I suspect that, for a variety of reasons, priority has been given to paying at least part of it down). It's a fair comment that the effective price for us would be whatever Short wants plus SBC. However, in my opinion, that total plus necessary investment to get into the PL again would still be significantly lower than the amount Ashley appears to want for you.
As far as I can see, there's more potential upside for a potential investor in buying SAFC vs NUFC, but that upside might require more time to achieve.
