Given the equity in your property, I would seriously consider re-mortgaging to pull out your share and then use the money to make a full and final settlement with creditors.
A 95% loan to value mortgage will raise approximately £202k after costs, thus releasing £26k, which would enable a decent offer to be made to creditors. The additional borrowings would cost approximately £140 per month on an interest only basis, which I imaging is far less that you are paying in monthly repayments.
The think to be careful of here, is that your income will fluctuate with the start up of your new business. If you are tempted to take out further secured borrowings, then you must be convinced that these can be repaid, as your home is at risk if you default. You will also need to get your wife to agree to this as she is a joint owner.
I do a lot of these types of voluntary arrangements in my practice, as creditors like them because they get paid earlier and it is a good way for you to put your debts behind you and move forward.
