Not sure I understand what you are doing, but it doesn't sound good.
Is all your non deductible debt paid off?
Yes, all non deductible debt from PPOR is paid off.
This will be refinanced and PPOR valued to draw equity from to use as a deposit.
1 loan will have the deposit in it for IP1
2nd Loan will be the investment loan (balance of purchase price for IP)
Same steps for IP2, IP3 etc
So each IP will have a deposit loan and the investment loan
