I can understand your desire to keep your home. There are lots of questions that need asking, and a lot of answers will unfortunately beget more questions - a non-exhaustive list is :
How much equity (as asked)
Are any of the £83k creditors secured (presumably not). If not and you were attempt an IVA your other creditors would probably out-vote MBNA.
Do you have a partner? If so do you jointly own your home and does your partner have any debts? Does he/she have an income? Is the contribution you make based solely on your income?
As a general principle, without something more (eg the introduction of equity) I would have difficulty recommending an an IVA to you if your disposable income is only £254 with debts of £83k. The answers you give to the above questions (which I imagine Payplan must have asked you before they recommended the DMP to you) will give us all a clue as to what you ought to be doing.

PS Sorry I started to reply before you issued your last post - hence I couldn't take into account your last posting. Your circumstances are not straightforward and it will be highly dangerous for you to rely solely on advice from this forum without any one of us having full knowledge of all material facts. You should seek a face to face meeting with an Insolvency Practitioner where your position and all your options must be fully discussed.
