You are correct that there may have been a change in the debtor's circumstances, but the post does not make this clear - and I suspect it would have done if there had been an issue. Perhaps the original poster could make this clear so that we may understand his case a little better.
My point - as an IP with extensive experience of managing IVA's for the benefit of the last poster - is that creditors are increasingly not accepting full and final offers which are put forward by debtors who simply wish to conclude their IVA early. Some IPs may not be aware of this - and at the end of the day the decision is not the IPs but the creditors.
From the creditors point of view, who have the benefit of the next three years of property appreciation (and accepted the counter risk of devaluation) and ongoing monthly contributions, there is a risk that this will not be viewed as a commercial settlement.
