Hi all. I am planning to buy a PPOR soon and would be grateful for some clarification about how to maximise the tax-deductibility of my debt. My situation: Partner and I both have $500k loans on one IP each, both with $300k in the offset accounts. We were looking to buy a $1.5m PPOR, using 20% deposit and $1.2m home loan The $300k deposit for the PPOR purchase would be taken from our funds in the offset account. Could we move the remaining $300k we have in our IP offset accounts into the PPOR offset account, such that we are maximising the debt in the IP loans and minimizing non-deductible interest repayments for the PPOR loan? The IPs are currently P&I loans for a lower rate. Presumably it would be prudent to refinance the IPs to IO before purchasing the PPOR and have the PPOR as P&I if we wanted to reduce repayments for the next 5 years? I have read that the tax-deductibility of debt is determined by the purpose of that loan, which I assume would still refer to purchase of the IP to generate rental income, and therefore it would be tax-deductible? If not, what should the approach be to achieve this, given this? If this is not able to be advised over a forum, what professional should I be seeing about this? (Someone who is an accountant and tax agent?) Thanks for any advice you can provide!
