Sorry - didn't know you had already provided this information.
The problem you have is that you have more equity in the property than you owe to creditors. An IVA is therefore unlikely to work. I suggest that you look at an equity release now and try and offer a full and final reduced settlement to your creditors.
Do make sure that you can afford increased mortgage payments, however, otherwise a sale of the property might be more sensible.
