Step One: Research,Deposit & Savings
Always do your research and have your deposit ready. You may find your current assets are enough for you to borrow but always seek more than one opinion when it comes to borrowing.
What are you goals? When? Where? How?
Step Two: Tax benefits
Purchase your first investment and understand the tax benefits VS no tax.
Step Three: Strategy
Have a strategy to paydown your mortgage and consider this against the benefits of leveraging off tax benefits.
