A senior registrar recently told us she’d been turned down by her bank’s online application before she’d even spoken to a human. Her income was “inconsistent” according to their algorithm. She earned $310,000 last financial year, but the problem wasn’t her finances. It was that standard mortgage assessments are built for people with nine-to-five salaries, and mortgages for doctors require a completely different approach.
This article explains exactly what that approach looks like, which lenders get it right, and what your file actually qualifies for.
Mortgages for doctors are specialist home loan products offered by select Australian lenders who recognise the income complexity, earning trajectory, and professional stability unique to the medical profession. These lenders apply modified assessment criteria, including LMI waivers up to 90-95% LVR, flexible treatment of overtime, on-call, and locum income, and in some cases higher loan-to-income ratios than standard applicants receive.
Why standard mortgages fail doctors at every stage
Most mortgage applications assume a simple payslip. One employer, consistent hours, no gaps. For a GP working across 3 clinics, a registrar mid-rotation, or a specialist with a mix of public and private billings, that framework breaks immediately.
The income assessment problem
Banks assess borrowing power using a “gross income” figure, then apply the APRA-mandated serviceability buffer of 3% on top of the assessment rate. That buffer is fixed. But how your income is classified before the buffer is applied makes an enormous difference.
Standard lenders typically shade locum income by 20%, exclude on-call allowances entirely, and won’t touch overtime unless it’s been consistent for 24 months. Lenders with specific doctor mortgage programs treat the same income differently. Some accept 100% of locum income from the day you start. Others include overtime after 3 months of payslips.
The difference in assessed borrowing power can be $150,000 or more on the same gross income.
The deposit and LMI trap
Lenders Mortgage Insurance exists to protect the bank, not you, and you are the one who pays for it. Therefore, for most borrowers, it kicks in when their deposit falls below 20% of the property value. For example, on a $1.2 million purchase, that’s a $24,000 insurance premium you pay, which the bank keeps.
Most major Australian banks waive LMI for doctors entirely, up to 90% LVR. Some extend that to 95% LVR. As a result, a doctor buying a $1.2 million property could buy with a $60,000 deposit instead of $240,000, with no LMI cost whatsoever.
This is not a minor benefit. It is, frequently, the difference between buying now and waiting four more years.
How doctors qualify for LMI waivers on their home mortgage
The LMI waiver is available to doctors at most stages of their career; however, most lenders do apply specific eligibility criteria.
Most lenders require you to hold an MBBS or equivalent and be registered with AHPRA as a medical practitioner. Beyond those two requirements, the criteria diverge significantly across lenders.
| Lender type | LMI waiver threshold | Eligible roles | Income requirement |
|---|---|---|---|
| Major bank (LMI specialist programs) | Up to 90% LVR | GP, registrar, specialist, intern | No minimum income floor at some lenders |
| Second-tier bank | Up to 85% LVR | GP, specialist | Minimum $150k income at some lenders |
| Non-bank lender | Up to 90% LVR | Broader allied health + doctors | AHPRA registration required |
Interns and first-year residents often assume they don’t qualify, and several lenders disagree, because as long as you hold provisional AHPRA registration and have a signed employment contract; therefore, some lenders will extend an LMI waiver from day one.
For specialists, the LVR limit is sometimes higher. A specialist earning above $250,000 per year may qualify for a no-LMI product up to 95% LVR at select lenders.
The best mortgage lenders for doctors: what actually separates them
There is no single “best” lender, because the right lender depends on your income structure, career stage, and whether you’re buying owner-occupied or investment, and what features matter most to you.
Therefore, several meaningful distinctions separate lenders worth considering from those worth avoiding.
Income treatment
This is the biggest variable. When comparing mortgage lenders for doctors, ask each one specifically how they assess these income types:
- Locum and contract income: Some lenders require 2 years of history. Others accept 3 months, or even just a contract.
- On-call and overtime: The best programs include these in full after a short seasoning period.
- Private practice income (company or trust): Most standard lenders treat this as self-employed income and apply much tighter criteria. A small number of doctor-specific programs assess it as professional income, with a materially different result.
Loan features that matter for doctors
Beyond the rate, consider which features align with how doctors actually use money. Most doctors in their 30s are in accumulation mode, often carrying HECS debt and building practice equity simultaneously. These features become more valuable:
- Offset accounts: An 100% offset account against your variable rate means every dollar in your everyday banking reduces your loan interest, without locking away money you might need for a practice purchase or investment.
- Interest-only periods: Useful for investors and practice owners who want to direct cash flow elsewhere. Some doctor mortgage programs allow up to 5 years interest-only on investment loans.
- Portable loans: If your training requires you to move cities, a portable loan lets you take the loan to a new property without breaking and reapplying.

Mortgage advice for doctors: the income types most brokers misread
Generic mortgage brokers encounter a doctor’s file once every few months, and the result is predictable. They default to the most conservative interpretation of your income, place you with whichever lender they use most, and present that as your only option.
On the other hand, a specialist broker encounters these files daily. They know which lender accepts contract income after one payslip, which one counts 100% of your Public Health Award overtime, and which one will approve a registrar mid-contract at 90% LVR without flinching.
What your file actually looks like to a lender
Most doctors don’t realise that their application file is genuinely attractive to the right lenders. Historically low default rates. Guaranteed income trajectory. A regulated profession. Professional registrations that create accountability.
Some lenders have entire divisions dedicated to medical professionals for exactly this reason, and they compete for your business. Therefore, a good specialist broker knows where the competition is sharpest and uses it to their advantage.
HECS debt and how it affects your borrowing power
HECS (technically HELP debt) is the tax-specific liability most doctors are still carrying into their 30s. Lenders include your compulsory HECS repayment in their serviceability assessment, which reduces your available borrowing power.
At $80,000 of HECS debt, your compulsory annual repayment is approximately $6,400, and lenders include that in your expenses. Across a 30-year loan term, the compound effect on borrowing power can be $40,000 to $60,000. That’s a solvable problem with the right lender and loan structure, but you need a broker who has done this calculation before, and not one doing it for the first time on your file.

Home mortgage for doctors at different career stages
The right approach to a doctor home mortgage changes significantly depending on where you sit in your career. Here is how that typically plays out.
Intern and resident (PGY1-PGY2)
Your income is lower, but your employment is guaranteed and your trajectory is clear. Several lenders view interns as exactly the right risk profile: low current income, very high future income, professional stability, and an AHPRA registration that creates accountability.
You may qualify for an LMI waiver from your first payslip. Your borrowing power will reflect your current salary, typically $85,000 to $110,000 depending on your award, state, and hospital type. However, a joint application with a partner can materially change this.
Registrar (prevocational and vocational training)
This is where income complexity peaks. You may be rotating hospitals, adding locum shifts on weekends, earning Public Health Award overtime, and receiving education allowances. Standard assessments miss most of this.
A specialist lender will assess your base salary plus a reasonable portion of demonstrable additional income. In practice, a registrar earning $180,000 in total remuneration can often be assessed close to that figure, not just their base award.
Additionally, an investment property loan may be worth considering at this stage. Buying an investment property during training, rather than waiting until you’re settled post-fellowship, can give you two to three years of capital growth and debt reduction before your income peaks.
Specialist and consultant
By this stage, your income is high but often complex: hospital employment, private billings, a company or trust structure, perhaps a share in a practice. Most lenders won’t know what to do with this file. A handful will compete aggressively for it.
At specialist income levels, the limiting factor is usually not serviceability but LVR. Some lenders will extend high-LVR products to specialists at loan amounts above $2 million, recognising the low risk profile of the borrower.
What to compare when choosing mortgages for doctors
When you are comparing doctor home mortgages, rate is one input. Here is the full comparison framework.
| Feature | What to look for |
|---|---|
| LMI waiver threshold | 90% LVR minimum; 95% available at some lenders |
| Income assessment | Locum included after 3 months; on-call counted |
| Offset account | 100% offset against variable rate |
| Serviceability assessment rate | Lower assessment rate = higher borrowing power |
| Portability | Essential if you may need to relocate during training |
| Interest-only availability | Up to 5 years for investment loans |
| Debt consolidation flexibility | Useful if you carry HECS and car finance |
Rate comparisons alone are misleading. A 0.05% lower rate on a loan assessed $200,000 below your actual capacity is a worse outcome than a slightly higher rate on the right loan size.
According to ASIC’s MoneySmart, comparison rates exist to account for fees beyond the headline rate. For doctor mortgages, even the comparison rate doesn’t capture income assessment policy differences. That’s what a specialist broker’s assessment does.
