Most doctors can borrow between $1 million and $3.5 million, depending on career stage, income structure, and which lender you approach. Two doctors on the same salary can get very different results depending on the lender.
Key Takeaways
- Doctor borrowing capacity in Australia ranges from around $350,000 for interns to $3.5 million+ for established specialists, with career stage being the biggest driver.
- Two doctors on the same salary can get very different results from different lenders, largely due to how overtime, HECS, and employment type are assessed.
- HECS/HELP debt, credit card limits, and dependent children are the three most common factors that reduce borrowing capacity unexpectedly.
- Some lenders have medical professional policies that allow higher LVRs, broader income inclusion, and LMI waivers, but these policies vary significantly.
- Small changes before you apply, like closing unused credit cards or documenting overtime properly, can make a meaningful difference to your final number.
How Much Can a Doctor Borrow for a Home Loan in Australia?
Most doctors can borrow between $1 million and $3.5 million, depending on career stage, income structure, and which lender you approach. The gap between lenders is significant, and two doctors earning the same salary can end up with very different borrowing capacities based on how that income gets assessed.
The Number Changes Dramatically by Career Stage
There is no single "doctor borrowing capacity" figure because your income and employment type shift a lot across a medical career.
Here are rough indicative ranges based on a single applicant with no dependants and minimal other debt:
- Intern (PGY1): $350,000-$500,000. Base salary around $75,000-$85,000, limited serviceability.
- Resident (PGY2-PGY3): $500,000-$750,000. Income creeps up, overtime starts to factor in.
- Registrar: $750,000-$1.3 million. This is where lender policy diverges sharply.
- GP (salaried): $900,000-$1.4 million. Stable employment, lenders treat this favourably.
- GP practice owner: $1.2 million-$2.2 million. Business income adds complexity but also upside.
- Specialist/consultant: $1.5 million-$3.5 million+. High earners with private billing assessed very differently across lenders.
These are indicative, not guarantees. Your actual number depends on your specific situation.
Why Two Registrars Can Get Wildly Different Results
Take James and Priya. Both are surgical registrars on the same base salary, around $120,000. Both have a HECS debt of $85,000 and no dependants.
James goes to his bank directly. They assess his income at base salary only, apply a standard HECS repayment reduction of roughly $700 per month, and decline to include his overtime. His borrowing capacity comes out at $820,000.
Priya uses a broker who knows medical lending. That broker approaches a lender with a medical professional policy that includes a portion of overtime and penalty rates as regular income, applies a more generous HECS treatment, and factors in her career trajectory. Priya's capacity comes out at $1.15 million from the same gross income.
Same salary. Same debts. $330,000 difference. This is why lender selection matters as much as your income level.
The Variables That Actually Move the Number
HECS/HELP debt is one of the biggest reducers that doctors often underestimate. Lenders treat it as a liability that reduces your monthly disposable income. On an $85,000 HECS debt, you might lose $600-$800 per month in serviceability. Some lenders are more generous in how they model this; others apply the ATO's full compulsory repayment schedule upfront.
Overtime and penalty rates are assessed inconsistently. Standard lenders typically require two years of consistent overtime history shown on payslips and tax returns. Some medical specialist lenders will accept 12 months, or count a portion of regular overtime from payslips alone.
Dependent children reduce borrowing capacity meaningfully. Each child typically reduces capacity by $80,000-$150,000, depending on the lender's living expense models (HEM benchmarks versus actual declared expenses).
Existing loans and credit cards hurt more than most people realise. A $20,000 car loan can reduce borrowing capacity by $100,000 or more. Credit card limits, even on cards you pay off monthly, count as potential liabilities.
ABN or practice income for GP practice owners and specialists with private billing gets treated differently again. Lenders typically want two years of tax returns, and if your income has been growing, they often average the two years rather than using the most recent, which can pull the number down.
How Medical Income Gets Assessed Differently
Standard applicants get assessed on base PAYG salary, plus proven secondary income with a full history. Doctors get some advantages, but only with the right lender.
Some lenders have dedicated medical professional policies that allow:
- Higher loan-to-value ratios without lenders mortgage insurance (LMI), often up to 90% or even 95% of the property value. See more on LMI waivers for doctors.
- More generous inclusion of overtime and locum income.
- Acceptance of shorter employment history when the applicant has recently completed training.
- Consideration of future earnings for registrars about to move into consultant or specialist roles.
Not every lender does all of these things. Some do one or two. The difference between finding a lender with a strong medical policy versus going to a generalist lender can be hundreds of thousands of dollars in capacity, or access to LMI waivers that save $20,000-$40,000 upfront.

What Actually Maximises Your Borrowing Capacity
A few practical levers that make a real difference:
Reduce or close credit cards before applying. Even a $10,000 limit on a card you never use gets counted. Call the bank and reduce limits or close cards you do not need.
Document overtime properly. Make sure your payslips clearly show regular overtime and penalty rates, and keep them. Two years of consistent records gives brokers much more to work with.
Check your HECS balance. If you are close to paying it off, clearing it before applying can free up significant borrowing capacity.
Avoid new car loans in the 12 months before applying. Timing matters. A car loan taken out right before a mortgage application is a double hit: it reduces serviceability and adds to your liabilities.
Talk to a broker before approaching a lender directly. The right lender for your situation is not always obvious, and going to the wrong one first does not improve your credit file.
