Ther is always a final review, so no worries on that point.
Regarding the property: Have you submitted valuations as required by the terms of your IVA and are awaiting the outcome, or has nothing at all been done ?
If the former, give your firm a chivvy up, if the latter, better get the ball rolling now, as it will have to be dealt with before completion can proceed.
My opinions are merely that .. opinions based on experience. Always seek professional advice.
IVA Completed 23rd July 2013 .... C.C. 10th January 2014
