Hi, I am after some clarification about what I need to do to ensure that my investment debt interest is deductible. Here is the hypothetical: - Investment loan of $200k with a lender (not CBA) - I have a CBA direct investment account (CDIA) with a $0 balance - My share portfolio is managed through CommSec. If I transfer money from the loan account directly into the CDIA and then buy shares through CommSec, will the interest definitely be deductible? I will make sure any left over funds are transferred back into the loan account after the share purchase is settled. Would it be better if I could settle the share purchase directly from the loan account (don't even know if it's possible). Also, should I have dividends paid directly into the CDIA also? Or direct them elsewhere? Thanks in advance, Bryce.
