Hi
Firstly, as you probably already realise, you ought not to be in a DMP and using other credit, so in that instance IVA's are probably a better way forward for you.
With regard to your property, it is likely that creditors will ask you to release equity based upon a property revaluation carried out in the final year of an IVA (when your house may have increased in value), and then release equity based upon 85% of the value of the property, less your existing mortgage.
CCCS now have their own internal IP I understand, but you also may wish to speak to an independent insolvency practititioner as well. An IVA should take no more than 6 - 8 weeks to put together, if all of your information is correct and present. Contributions based IVAs generally run over at least 5 years.
