My partner and I are buying a second property at the moment and it's going in her name (FHB concessions). My current property will become an IP and the new one will be our PPOR for the short term. When getting the loan, I am using the equity in my current property as a deposit on the new one. The bank has structured the loan so that I have a second mortgage on my house to pay 20% of the new place. The bank wants it setup like this: Property 1 - Owned By Me - $400k loan (just my name), $700k value Property 2 - Owned by partner - $400k loan (both names), $500k value Loan for $100k deposit to be added to Property 1 in MY name. My problem is that I assume that the $100k loan will NEVER be tax deductable for me as Property 2 will be in my partners name. We intend on refinancing the house 100% to her name before we move out but if she pays out my $100k loan then can she claim that interest? If I add her name to the $100k second mortgage then does that act as proof of anything or can she refinance that into property 2 later? What do we need to do to make it that in the future all of the interest on both properties is claimable. Please remember that the properties are each in only 1 name! Thanks!
