I’m not sure if your post was intended as a humour and/or it is serious. But if you are seriously considering a major investment, definitely go in with your own eyes open and don’t rely purely on the advice or financial planners or others. I believe it is important to understand the numbers yourself rather than simply take the ”it’ll all be fine” from an advisor.
I’d suggest setting up a spreadsheet to model any possible scenarios, and to calculate all the income, outgoings, and all the taxes (and tax benefits) associated with each transaction. The taxation is probably the complicated part, but all the tax information should be available on the ATO website (along with how they are calculated). It can become quite involved, but I do think it is good to be full across all the numbers.
I would also suggest doing the same modelling but with using a standard industry fund superannuation as the investment vehicle and see how the numbers stack up as well. The tax on superannuation can be somewhat complex too as super can fall in to four different taxation buckets (’taxed-taxed’, ‘untaxed-taxed’, etc.) and have different tax implications for contribution, earnings, and the benefit at the time of withdrawal.
Or combine both and enter property investment under a superannuation umbrella.
Both property investment and superannuation have tax benefits, but they are quite different investments and quite different risks.
In a nutshell - go in with your own eyes wide open.
