Refinance costs

We recently refinanced our loans, our PPOR loan was increased and then split into 3 separate loans - 1 for PPOR, other 2 for investment properties. I'm assuming with the discharge costs and refinance costs, I then split these 3 ways to claim the appropriate one for tax?

 

It depends how it was done. Where costs directly relate to an existing rental property they would be deductible in the year incurred.
