I've been reading and doing the calculations. And I got more confused. My mortgage rate for investment property is higher than the OO property.
We should always pay off higher rate loan first. What do I do when higher rate loan has tax deduction? Shall I discount the higher rate by MTR (e.g. 30%) before comparing?
Another confusion is interest only option for negative geared investment property. We pay more interest over the term of the loan when doing interest only. But some articles says it does not matter as it has tax deduction.
Basically how does the tax deduction affect the repayment?
It doesn't, you may get a tax deduction when you submit your tax return.
