If your IVA completes next July then you shouldn't be worrying about debt management quite yet!
As long as you keep up to date on your secured payments / mortgage then your home would most likely be safe on a debt management plan- talk to your IP though, as they will already know the terms of your IVA and if anything is secured against your property.
It sounds like you should phone your IP anyway, just to find out exactly what they need and the quickest way to get them the information. Explain what the advisor told you and insist that they write to your creditors.
Which company are you with, if you don't mind me asking? We might be able to put you in touch with someone helpful!
