Is your investment property loan on principle and interest payments?
basically the way I would make the decision for myself would be by looking at the following.
1, If I keep the money in the offset account, I am reducing the interest on the loan, but therefore increasing the principle payments and paying the loan off faster, which means the property will become positive cashflow faster.
2, if I take the money and invest else where the investment property will continue paying itself off just at a slower rate, but I would have more cashflow coming in from the franked dividends, that can be used to continue to build your share portfolio.
on a side note do you understand what franked dividends are and how they work? (sorry it seems like a simple topic but you would be surprised by how many people don’t understand them)
