Hi there
We can deal with these sort of questions for you off-line - but so that other forum members can also benefit - here goes!
1 Where property prices are rising, get the valuation done as early as possible, if house prices are falling, it is better to hang on. You will have to take a decision on this at the time. Your IP will accept a valuation completed by the original agents.
2 You can renegotiate, but any deviation from the original IVA terms will need to be agreed by creditors at another creditors meeting.
3 Yes and if you can remortgage sufficient to pay creditors and costs in full the IVA will be brought to a satisfactory conclusion.
4 Your redemption figure has already been taken into account in the mortgage figure confirmed to creditors.
