Top Strategies to Maximise Your Borrowing Capacity

Lenders assess your borrowing capacity by comparing your income against your committed expenses and existing debts. For public health dentists, that calculation becomes more complex than it does for practice owners or purely private clinicians because your income structure sits somewhere between straightforward PAYG employment and variable contractor work.

Your base salary appears consistent on paper, but additional income from locum shifts, after-hours work, or sessional payments at different facilities can be treated inconsistently across lenders. Some will count the full amount after three months of consistent earnings. Others will average it over twelve months or exclude it entirely if they consider it variable or non-guaranteed income. That difference alone can shift your borrowing capacity by $100,000 or more.

How Income Verification Works for Public Health Dentists

Lenders verify your income using payslips, tax returns, and employment contracts, but the weight they place on each document changes depending on how your employer structures your pay. If your contract shows a guaranteed base plus overtime or locum provisions, some lenders will include the additional income immediately while others will want to see it paid consistently over six to twelve months.

Consider a public health dentist with a base salary of $140,000 who regularly works locum shifts that add another $30,000 annually. One lender might assess capacity on $140,000 only, while another with more flexible serviceability policies will use the full $170,000 after reviewing three consecutive payslips showing the additional income. That $30,000 difference translates to roughly $150,000 in additional borrowing capacity at current variable rates, which can determine whether a property is within reach or not.

We regularly see applications declined or approved for lower amounts than expected because the broker or applicant assumed all lenders would treat public health income the same way. They do not. Choosing the right lender upfront, based on how they assess your specific income structure, avoids wasted time and protects your credit file from unnecessary enquiries.

Reducing Committed Expenses Before You Apply

Your borrowing capacity is not just about how much you earn. Lenders subtract your committed monthly expenses, existing debts, and a buffer for living costs before calculating how much they will lend. A car loan with $600 monthly repayments reduces your borrowing capacity by around $120,000. A credit card with a $15,000 limit can reduce it by $30,000 to $45,000, even if the balance is zero, because lenders assume you could draw the full limit at any time.

Paying out a car loan, closing unused credit cards, or reducing limits on the cards you keep all increase your borrowing capacity without changing your income. If you are planning to apply for a home loan within the next few months, review your existing debts and credit products now. Closing accounts takes minutes but the impact on your serviceability can be significant.

Some lenders also assess your living expenses using either your actual declared spending or a benchmark figure based on the Household Expenditure Measure (HEM). If your actual spending is lower than HEM, declaring it accurately with supporting bank statements can improve your borrowing capacity. If your spending is higher, lenders will typically use HEM instead, which works in your favour.

Using Offset Accounts to Build Equity and Improve Future Capacity

An offset account linked to your home loan reduces the interest you pay without changing your repayment amount, which means more of each repayment goes toward reducing the principal. That builds equity faster, and equity becomes the foundation for future borrowing if you want to purchase an investment property, upgrade, or renovate.

If you are earning locum income irregularly, directing that income into an offset account keeps it accessible while reducing your interest costs. It also demonstrates savings discipline to lenders when you apply for refinancing or a second property loan, because they can see consistent deposits and a growing balance rather than irregular income disappearing into general spending.

Some lenders offer full 100% offset accounts while others offer partial offsets that only reduce interest on a percentage of the balance. The difference matters if you are holding significant cash reserves. Full offset accounts deliver better value and should be prioritised when comparing home loan features.

The Role of Loan Structure in Protecting Borrowing Capacity

How you structure your loan affects your financial flexibility and your ability to borrow again in the future. A variable rate loan with an offset account gives you full flexibility to make extra repayments and redraw funds if needed. A fixed rate loan locks in your rate but typically removes redraw access during the fixed period, which can limit your options if your circumstances change.

A split loan, where part of your loan is fixed and part is variable, balances rate certainty with flexibility. You can make extra repayments into the variable portion while protecting part of your loan from rate increases. That structure works well for public health dentists whose income includes both a stable base and variable additional earnings, because you can direct surplus income into the variable portion without penalty.

Getting loan pre-approval with the right structure in place gives you a clear borrowing limit and confidence when you start looking at properties. Pre-approval also signals to sellers that you are a serious buyer, which can strengthen your position in negotiations, particularly in markets where multiple offers are common.

How Lenders Assess Future Earning Potential

Some lenders take your profession into account when assessing risk, particularly for dentists. They recognise that dental professionals have strong earning trajectories, low unemployment rates, and stable career paths. That recognition can translate into more flexible serviceability policies, lower interest rate discounts, or LMI waivers at higher loan to value ratios.

For public health dentists, this matters because your income may increase as you take on additional sessional work, move into senior roles, or transition into private practice. Lenders who understand the dental profession are more likely to assess your application based on your current and projected earning capacity rather than treating your income as static. That difference can mean approval where another lender would decline, or a higher borrowing limit that reflects the full scope of your financial position.
