Thank you for the question.
I'm not familiar with debt dumping or double dipping specifically, but I can comment that the deductibility of interest and the rules surrounding it are one of the most extremely frustrating issues we have to deal with.
We would like to see the expert panel that we suggested address this particular issue as well as the many other issues on simplification. And the other issues are actually suggesting the expert panel.... When you're advising a client who asks you, “Is my interest going to be deductible because I've refinanced, I've done this, that, and the other thing”, it's very difficult to give him a solid answer and know that you're absolutely right under those circumstances.
It is an issue, however, that our association would be pleased to address, and we can bring more information to the table.
