You mention that you are only on $70k. I'm not sure of your working situation, or if it is possible for you to raise that income in any way, and all the big income earners here would say to concentrate on earning more.
Anyway, I know that this is not possible for many people, and if this is true for you, then you will need to look closely at the numbers of anything you decide to purchase, because your serviceability will be hit hard if your next investment has a similar yield to your last.
I'm not saying that your first IP is/was a bad investment, it's probably had a fantastic CG, I'm just kind of asking how many properties do you think you can hold, on your income, if you are losing $100pw (or more) on each one. Now, think carefully, how many of them can you hold that cost you nothing each week? Or better yet, put even $10pw into your pocket?
