Let's just assume you are 30 years old and have dual citizenship (Aus and another country) and accumulated a savings of AUD400,000 cash.
Buy a property in Melbourne which costs ~AUD800,000 (3BR townhouse) and continue paying off the mortgage for "X" number of years.
Buy a property in country "Y" which costs ~AUD250,000 (3BR landed house) in cash. You will have an excess of ~AUD150,000 with a low cost of living. (3x lower cost of living)
Your salary will still be paid in AUD as most companies allow remote working now. Worst come to worst, you will have to find a remote job elsewhere.
My preferred option will be B as I don't have a huge financial burden and I can live and travel as I wish.
What do you think?
