Hi jm and welcome to the forum
If your are seriously thinking about an IVA, the first thing to do is to work out what disposable income you would have each month to offer to creditors. This is worked out by taking your combined salaries, any child benefits you may have or other income, and deducting usual household and personal expenditure allowing for some contingencies.
You will also need to work out what equity (if any) you currently have in your property, as the creditors will expect some of this to be released to them during the IVA as well.
If you can post more information, then one of the experts will be able to help you further - or alternatively take specific advice from an insolvency practitioner.
