Personal Finance

Q I'm 25, single, earn $70,000 a year, and have no debt. I have $50,000 in a savings account and $120,000 in shares ($60,000 as a margin loan). For my next investment step, I am unsure as to whether I should invest more money into shares or should I diversify and buy an investment property? If buying an investment property, what is the minimum recommended deposit and what type of loan is the most suitable and why?
