Portfolio Lending Strategies

Before the first purchase, it helps to have a rough picture of where you're heading. Are you aiming for two well-chosen properties you hold for decades, or a larger portfolio that you later reduce? Do you want growth, income, or a balance? Your answers shape whether you lean towards interest-only or principal and interest, which lenders suit you and how much buffer you need.

A plan doesn't have to be rigid. It just means each loan you take on supports the next step rather than blocking it.

It's also useful to think about how you'll eventually reduce debt. Some investors plan to sell one property later to pay down others, some aim to switch everything to principal and interest over time, and others focus on clearing the home loan first. Knowing your exit approach helps you choose the right loan types from the start.

Most of the portfolio problems we see come from structure set up in a hurry. The aim is that each property can be sold, refinanced or revalued without dragging the others along.

Early on, deposit or equity tends to be the barrier. As a portfolio grows, serviceability usually takes over. Each new loan is tested at a buffered rate, existing loans are assessed conservatively, and only part of the rent is counted. Eventually most lenders will say no, even if you have equity.

This is where lender order matters. Some lenders are more generous with rental income or assess existing debts differently. Using those lenders at the right time, and not using up your capacity with the most conservative lender first, can extend how far you can go. Policies change, so this needs regular review.

More properties means more exposure to vacancies, repairs, insurance increases, land tax and rate changes. A cash buffer, whether in an offset account or as undrawn equity, gives you time to respond without being forced to sell. We'd generally rather see an investor buy one property fewer and sleep well at night.

As a general guide, many investors aim to hold several months of total portfolio repayments and expenses in reserve, though the right amount depends on your income stability and the properties you own. Our cash buffers guide covers this in more detail.

Once a year is a good rhythm for a portfolio review. Check rates against the market, interest-only expiry dates, fixed rate expiry dates, valuations, rental income and your own goals. Small adjustments, such as a rate negotiation or a refinance, can add up over a portfolio.

A review is also the right time to ask whether the portfolio still suits your life. Family needs, work plans and risk tolerance change, and a portfolio that made sense five years ago may need adjusting. We review our own lending regularly for the same reason.
