Hi guys I was wondering if anybody could help me with my situation to see if there is anything I could improve/change. I have an IP with an IO loan in my name only. The interest for this loan is debited from an account which is in my name and my wife's name. Because the interest is deducted from an account which has dual ownership, does it mean that I can only claim half the interest expense as a deduction? Also, similarily I have a LOC for investing purposes (mainly shares) which is in my name and my wife's. The interest for this LOC is debited from another dual owned account. So who gets to claim the interest as a deduction?
