From what I gathered from to court reports, the house was bought in Feb 17 for £435k with a £300k mortgage attached so there will be some equity to cover the existing debts. It was re-valued at £505k for the purpose of the fraudulent loan.
Given that the mortgage will have probably gone unpaid since Sept 2017 and all other debts will be accumulating interest and the house will be sold at rock bottom price, there won't be much left by the time it is all settled. As house where a murder occurs won't be catching top price at a sale, probably will be auctioned for much less than real value.
I don't think he will have a penny left when everything is finally sorted out.
