You will need to wait until your completion letter arrives and your credit record is clear.
Sharing from experiences of dealing with debt
The greatness of a man is not in how much wealth he acquires, but in his integrity and his ability to affect those around him positively.

Until you get the completion certificate you are still in an IVA. And, while it is on record ( 6 years from the start) you will find it hard to get a loan and less than 'break your legs' rates.
My opinions are merely that .. opinions based on experience. Always seek professional advice.
IVA Completed 23rd July 2013 .... C.C. 10th January 2014
