If you are insolvent - ie you have recognised that you cannot continue to service your debts on time - then you ought to take specialist advice as to your options - and IVA will be just one of them. Your house will be safe under IVA proceedings, but you will be required to raise some money from the equity during the final year. If the equity is less than £5,000 - having sought refinance based upon 85% loan to value - then you will not be required to do this, but of course you will have to fund contributions over a five year period, and this may be difficult to afford without your wife's contribution and the fact that you will be paying child maintenance.
