Thank you so much Richard for your great thought.
I am not at high income level at this stage. If I use my existing equity to buy IP then I should have 3 separate loans, my PPOR + equity+ the rest for covering IP price, So my main concern is if I am eligible to get such amount of the loans?

and second question: could you please explain this more for me:”Remember it likely if your IP loan is > 80% it will have to principal & interest so why not maximize the deductions”.

Thank you so much for your time.
