If I pay the stamp duty upfront for an Investment Property, can I deduct it?

[tinky]

Hello all,

I'm hoping you can help. We are about to purchase an investment property and will be borrowing more money to assist in funding it.

We currently have money in our redraw account and I was told that if I paid the stamp duty portion of the new house with these funds (rather than including them in the new mortgage) I could claim it as a one off deduction in my tax return as it is for investment.

Can someone confirm if the above is true or where the ATO website might explain this (I've had a look but can't find anything specific).

thanks in advance
