You should not contact your creditors directly, and I would be suprised if you would find anyone prepared to talk to you to be frank. Or anyone with the ability to make a decision.
Depending upon this lady's level in the food chain of your IP firm - it is impossible to tell whether the IP will put the offer forward.
Nothing like the horse's mouth when you want a decision, and to be quite frank I am getting fed up of reading on this forum that members of my profession "do not take calls".
If the offer is acceptable, you will need to get a firm offer of re-mortgage before the IP will put this to creditors.
