So you have a relatively low level of debt, and low monthly disposable income. Given the level of your equity in the property, I am suprised that an IVA was suggested to you to be frank.
If you were to sell your property - either on the sale and leaseback option or a straight sale and new rental agreement elsewhere, the money that you would be saving would easily enable you to repay your debts under normal contractual terms. But with a sale and leaseback option, you may probably only be offered 80% of the value of your property, so this will not even cover the current mortgage.
A straight sale will give you enough money to relocate and pay a chunk off your creditors, leaving you with affordable repayments. I think that you could be debt free within three years.
Is your Supervisor saying that he will make you bankrupt due to your default with the IVA?
