As Andy says, in an IVA, it is usual for the proposal to expressly exclude personal and domestic assets. So if you are selling this type of item, there is no need to hand over any of the sale proceeds.
If, however you are buying in to sell on, then you are trading, and hopefully generating profits. To this end you need to register with HMRC for tax purposes, ensure that you pay over tax on your profits, and then 50% of the income earned is payable to your IVA.
