You out-earned the staff specialist whose list you covered in March. The bank still said no. Getting a locum doctor home loan in Australia rarely comes down to how much you earn: it comes down to how a lender reads the way you're paid, and most read it badly. Change the reader and the answer changes. Put the same income in front of a lender whose policy recognises locum work, structured the way their credit team expects to see it, and a declined file can become an approvable one.
The timing is better than the headlines suggest. The RBA's cash rate sits at 4.35% after hikes in February, March and May 2026, and Cotality's June 2026 data has national auction clearance rates stuck in the low 40s. That is a rising-rate market: fewer buyers at open homes, vendors meeting the market, more room to move on price. For a locum with a healthy day rate and a deposit taking shape, this is a preparation window. The next RBA decision lands on Tuesday 11 August 2026, and the doctors who spend the weeks before it getting their income evidence in order will be shopping with an advantage most buyers have surrendered.
Why do lenders misread locum income?
Most locums are paid one of three ways: through an agency's payroll as a casual employee, through their own ABN as a sole trader, or a mix of both depending on the placement. None of those look like a salary. That is the whole problem.
A credit assessor doesn't see "in-demand specialist covering a workforce shortage". They see casual income, or self-employed income, and each one triggers its own rulebook. Casual income usually needs three to six months of continuous history before it counts, and it is often averaged or shaded on the way through. Self-employed income is harsher again: most lenders want two full years of tax returns, and most Big 4 banks won't take locum income seriously without at least 12 months of history behind it. Your first ABN year, the lean one while you built up the circuit, drags the two-year average down long after your day rate has doubled.
Borrowing capacity is built from assessed income, not actual income. Once a lender shades $260,000 down to $160,000, the damage is done before the calculator even runs. Our guide to how borrowing capacity works covers the mechanics in full.
You're not a risky borrower. You're a misfiled one.
You've probably absorbed the story that locum work makes you unbankable. Flip it. A locum GP with standing offers from three agencies has more income security than most salaried workers, not less: if one hospital's budget tightens, two others are already calling. AHPRA registration doesn't lapse because a placement ends.
The risk story is a filing story. We've seen a locum anaesthetist's $2,400 day rate assessed under the same rule as weekend retail shifts, because nothing in the application explained what a locum is or how the bookings roll forward. Same doctor, same income, different lender and a properly built file: a very different answer.
Follow the chain through. Income gets misread, so it gets averaged and shaded. Capacity shrinks by six figures, so the doctor either waits years longer to buy or keeps renting through the highest-earning decade of their career. The fix costs nothing. Evidence the current run-rate properly, and choose the lender before the lender chooses the rule.
How does the way you're paid change what you can borrow?
The same $260,000 can be counted four different ways. This is where locum files are won or lost.
| How you're paid | How most lenders read it | What that does to your file |
|---|---|---|
| Agency payroll (PAYG casual) | Casual-employment rules: 3–6 months' minimum history, income often averaged or shaded | A strong recent run-rate gets diluted |
| Your own ABN (sole trader) | Self-employed rules: typically two full years of returns, start-up year included | Your worst year prices your best year |
| Mix of agency and ABN | Each stream assessed under its own rule, sometimes with the smaller one ignored | Complexity invites conservatism |
| Specialist medico policy available through Wity | Locum income evidenced from recent invoices, agency statements and BAS; future income can be considered for doctors where the pathway is documented | Assessed closer to what you earn now |
Two of those rows also apply to hospital doctors carrying heavy penalty shifts. If a chunk of your income is rostered extras rather than locum bookings, our piece on how lenders treat bonus and overtime income is the companion read. And for registrars whose earnings are about to step up sharply, future income policies can matter more than anything in that table.
What can a locum GP actually borrow? Same doctor, two paths.
Meet Dr Callum Reid: locum GP, Brisbane-based, two years on the Queensland circuit with regular blocks in Emerald and Longreach. Current-year income of $260,000, a first ABN year of $145,000 while the bookings built up, and $65,000 of HECS still on the books.
Path A, a typical bank. The two years get averaged to about $202,500, then shaded to roughly $162,000 of assessed income. His HECS repayments carve away more: under standard treatment, a debt that size typically costs a doctor $70,000 to $90,000 in borrowing power (HECS and borrowing power, explained). He's offered around $720,000, and with less than a 20% deposit saved he'd also wear an LMI premium that typically runs $12,000 to $18,000 at that loan size.
Path B, the Doctors & Dentists policy through Wity. His income is evidenced from agency statements, invoices and BAS at its current level. His HECS is excluded from the calculation entirely. His capacity models at roughly $1.1 million, he can borrow up to 95% with no LMI, and a 35-year term is available to keep repayments manageable while he keeps flying. On a $1 million home in Wavell Heights with a 5% deposit, the waived LMI alone is worth roughly $30,000, before counting the 30 years of interest he would have paid on it.
The gap: close to $400,000 in borrowing power, plus about $30,000 in LMI he keeps. Same doctor. Same bookings. Different reader.
Based on typical scenarios. Individual outcomes vary.
How do you strengthen a locum doctor home loan application in 2026?
Start ninety days out, not the week you find the house. Lenders approve what they can verify, so the job is making your income easy to verify:
- Keep the paper trail tight. Agency remittances, invoices, BAS, and your booking calendar for the next quarter. A forward diary of confirmed placements answers the continuity question before an assessor asks it.
- Don't restructure mid-stream. Switching from agency payroll to your own ABN three months before applying restarts the history clock with most lenders. Move after settlement, not before.
- Mind the 2026 rules. APRA held its 3% serviceability buffer at the 28 May 2026 review, and since 1 February 2026 lenders can write no more than 20% of new loans at debt-to-income ratios of six or above. High earners with thin evidence are exactly who gets squeezed, so lender choice matters more than it did a year ago.
- Model before you apply. The Wity Borrowing Power Assessment models your capacity across 45+ lenders rather than one bank's calculator, using your real locum income structure. That's how a locum psychiatrist discovers one lender reads her at $690,000 and another at $1.05 million, before a single credit enquiry touches her file.
If you're earlier in the process, the complete doctor home loan guide walks through the whole medico policy, from deposit tiers to settlement day.
