If you have already consulted an insolvency practitioner, they ought to be advising you on these points as they have detailed knowledge of your case. Your main problem with all of this is that Northern Rock are unlikely to accept an IVA where they have the prospect of a Charging Order in their sights. And they are a creditor who hold more than 25% of the vote.
I would suggest that you get an offer in principle - where credit checks are undertaken but a formal valuation has not yet occured - to see how much you can borrow, and then try your luck. Personally I am suprised that you have found an IP willing to take this case on as an IVA, given the current climate with Northern Rock's voting policy.
