As a Junior Doctor in Australia, you have a financial profile that standard bank algorithms hate: “messy” income with overtime and penalty rates, rotating 12-month contracts, and complex salary packaging arrangements.

How to Increase Borrowing Power as a Doctor

If you have used a standard borrowing power calculator and been disappointed, do not panic. Your “standard” borrowing capacity is often hundreds of thousands of dollars lower than your actual capacity.

While most advice focuses on the LMI Waiver for doctors (which helps with your deposit), this guide focuses on Serviceability: how to maximise the amount the bank will actually lend you.

Here is the ultimate guide to hacking the home loan policies for doctors in Australia for 2026.

🚀 1. Using Overtime to Increase Borrowing Power

Many doctors think they need to work overtime forever to afford a loan. You don’t. You simply need to demonstrate a higher income level during the assessment window. This includes the period leading up to pre-approval with a lender, as well as the final unconditional approval once you have found the property of interest.

The Strategy: Banks typically assess your income by “annualising” your last 2-3 payslips or your Year-To-Date (YTD) figure.

• Action: For the 3 months leading up to your pre-approval application, aggressively pick up high-yield shifts (Weekends and Public Holidays). You should aim to do the same during the period leading up making a purchase (making an offer or attending an auction), as lenders usually re-request proof of income.
• Result: The bank views this higher income level as your “permanent” salary, drastically increasing your borrowing limit.

Case Study: The PGY2 Resident “Sunday Boost”

Let’s look at the numbers for a standard PGY2 Resident in NSW.

• Base Salary: $89,000 (approx)
• Base Rate: ~$45.00 / hour
• The Shift: One extra 8-hour overtime shift per week (Sunday).
• Penalty Rate: 200% (Double Time for Sunday Overtime).

The Calculation:

Component	Math	Result
Gross Pay per Shift	($45 x 2.0) x 8 hours	$720 / week
Annualised Extra Income	$720 x 52 weeks	$37,440 / year
Total Assessable Income	$89,000 (Base) + $37,440 (OT)	$126,440 / year
Borrowing Power Boost	$37,440 x ~6 (Serviceability Multiplier)	+$224,640

💡 The Verdict: By working just one extra shift a week leading up to your application, you can increase your property budget by over $220,000. This is of course an overkill example.

🏦 2. Finding The Right Lender For Doctors

Working the overtime is only half the battle. You must ensure the bank counts it.

Generic lenders view overtime as unstable because for most professions they are inconsistent. They apply a risk filter called “shading,” often counting part of your penalty rates.

• The Risk: If you earn $40k in overtime, a generic bank might ignore $8k of it. That reduces your borrowing power by ~$50,000.

The Fix: Use a lender with a specific Doctor Loan Policy.

Fortunately, the major Australian banks are known to accept 100% of overtime and allowances for hospital-employed doctors, provided you can show consistency (e.g., 3 months of payslips).

ANZ Bank is known to accept only 1 year of tax return statement as proof of income for doctors with ABNs or side incomes (VMOs, GPs, dentists, private practice).

BOQ Specialist can offer home loans to doctors based on your future salary which is particularly useful if you have a contract for a higher role starting soon. For example, if you’re a senior registrar or fellow and already have an offer for a consultant specialist position.

📉 3. Reduce Your Expenses (But Don’t Starve Yourself)

A common myth is that living on instant noodles for 3 months will skyrocket your loan limit. This is often false because of the Household Expenditure Measure (HEM).

Banks do not just take your word for it. They use a “Greater Of” calculation to determine your monthly spending.

🧮 How Banks Calculate Your “Living Expense”

When assessing your borrowing power, the bank runs two numbers side-by-side and picks the highest one.

1. Your Declared Expenses: The budget you fill out in the application (groceries, transport, bills, insurance).
2. The HEM Benchmark: A statistical average of what a household of your size, in your location, with your income level spends.

What Factors Affect HEM?

The HEM is not a flat number; it is a dynamic benchmark that scales based on four main variables. Because you are a doctor (high-income earner), you are automatically placed in a higher “bracket” for several of these factors.

• Household Income: The HEM assumes that as you earn more, you spend more on discretionary items (better food, nicer clothes, more entertainment).
• Geography: Living costs vary by state and postcode. Living in Sydney or Melbourne triggers a higher HEM than living in regional NSW or Queensland due to higher cost of utility, transport and services.
• Household Composition: Every additional person adds a statistically calculated cost to the household.
• Lifestyle Standard: Banks categorise borrowers into bands such as Student, Basic, Moderate, and Lavish.

Scenario A (The Frugal Doctor): You declare you spend $1,500/month. The HEM for your income bracket is $2,400. The Bank uses $2,400. The result is that your frugality adds $0 to borrowing power, but of course will help you accumulate savings).

Scenario B (The Spender): You declare you spend $3,500/month. The HEM is $2,400. The Bank uses $3,500. The result is that your borrowing power drops).

The Takeaway: You cannot “budget” your way out of the included items (because the HEM floor applies). If you reduce your spending below these numbers, the bank ignores it and uses the HEM anyway. Focus on increasing income. However, you can improve borrowing power by minimising the Excluded items—for example, by closing credit cards or paying out a small HECS debt.

🍬 4. Salary Packaging

Salary Packaging allows you to pay for certain living expenses with pre-tax dollars.

Most Australian employees pay income tax on their entire salary, and then pay for bills with what is left. As a Public Hospital employee (JMO/Registrar/Staff Specialist), you have a special status (FBT Exemption) that allows you to take a portion of your salary out before tax is calculated. Therefore, salary packaging increases your net cash flow.

Read Salary Packaging for Doctors Guide.

However, when you salary package, your hospital payroll reduces your Gross Taxable Income on your payslip.

• Real Salary: $120,000
• Payslip Taxable Salary: $108,340 (because $11,660 was taken out)

If a generic bank algorithm looks at your payslip, it sees an income of $108,340. It calculates your borrowing power on that lower number, potentially costing you ~$70,000 in borrowing capacity.

A competent broker or Medico-specialist lender performs a manual calculation where they add back the salary packaging deduction to the taxable income to more accurately reflex your earning potential.

💡 Pro Tip: Inform your lender or broker that you are salary packaging. Always provide 3 months of bank statements alongside payslips. This proves your actual net take-home pay, which often overrides a confusing payslip.

🎓 5. HECS/HELP Debt

Should you pay off your HECS debt before applying for a doctor home loan?

A common confusion for doctors is thinking the size of the HECS debt matters. It does not.

• Doctor A: Owes $150,000, earns $100k.
• Doctor B: Owes $5,000, earns $100k.

Both doctors have the exact same reduction in borrowing power. The bank calculator only cares about the mandatory monthly repayment, which is based 100% on your Repayment Income, not the total HECS debt.

As of July 1, 2025, the HECS repayment system is now marginal. You only pay HECS on what you earn above the new threshold ($67,000).

Because of the new 15% marginal rate on income between $67k–$125k, the impact on JMOs is now manageable, while registrars face a significantly higher hurdle. Whether you should pay off your HECS debt depends on your financial and career situation.

Strategic Exclusion of HECS from Serviceability Assessments

Historically, even small HECS debts reduced borrowing power significantly because lenders treated the monthly repayment as a fixed financial commitment. However, recent policy shifts now allow certain major banks to remove HECS repayments from serviceability tests if the debt is deemed ‘low’ or is on track to be cleared soon. By ignoring this liability during the assessment phase, lenders can offer a much higher borrowing limit to eligible applicants.

🏠 6. Investment vs. PPOR: Understanding “Rentvesting”

For many junior doctors, the traditional goal of buying a “forever home” (PPOR) immediately is financially impossible or logistically unwise due to hospital rotations. T

An alternative strategy is “Rentvesting” – renting where you need to live (near the hospital) while buying an Investment Property (IP) where you can afford or where growth is better.

Applying for doctor home loans for IPs would increase your borrowing power. Here’s why:

1. Rental Income: Banks add ~80% of the rent to your income.
2. Negative Gearing: Tax deductions on interest can improve serviceability.

This is a popular strategy for JMOs: Buy a high-growth investment property now to lock in a price, while renting where you want to live near the hospital.
