Most investors focus on the rate. Experienced ones focus on structure, because the way a portfolio is arranged determines how much you can borrow next time, how exposed you are if one property underperforms, and how much flexibility you have when circumstances change.
When lenders secure multiple properties against each other, it feels efficient and often is, in the short term. The problem appears later: selling one property, refinancing, or releasing equity becomes tangled, because every decision touches every property.
Keeping securities separate – sometimes across different lenders – costs a little more effort up front and preserves a great deal of flexibility. Whether it's right for you depends on your plans, but it should be a deliberate decision rather than something that happens by default.
Interest-only periods improve short-term cash flow and can have tax implications worth discussing with your accountant. They also mean you aren't reducing the debt, and repayments step up noticeably when the interest-only period ends.
Lenders assess interest-only applications differently and often price them higher. It's a legitimate tool used deliberately, and a problem when used to make an unaffordable purchase look affordable.
Investment applications live or die on how income is presented – rental income treatment, negative gearing, existing commitments, and how each lender applies its serviceability assessment. Lenders differ substantially here, and knowing which ones treat your situation favourably is most of the work.
Often yes. Accessing available equity is one of the most common ways investors fund a deposit. How much is available depends on your property's value, your current loan balance and the lender's lending limits. See our page on equity and cash-out.
Not necessarily. Spreading a portfolio across lenders can preserve flexibility and avoid concentration limits, though it adds administration. The right answer depends on how many properties you plan to hold.
Lenders typically apply a discount to rental income rather than counting it in full, and the discount varies by lender. This is one of the main reasons borrowing capacity differs so much between lenders for the same borrower.
