What do Lenders See when a Locum Doctor Applies for a Loan?

Can Locom Doctors get a home loan?

To answer upfront, yes; locum doctors can get a home loan, but lenders will treat your income as variable, not salaried, which means the paperwork and the assessment look different from a standard PAYG applicant.

Locum Doctor Home Loans: What Lenders Actually See

Ask a locum doctor why they haven't bought yet and you'll often hear a version of the same sentence: "My income's too messy for a bank."

It usually isn't. Most of the time, the income has been perfectly adequate. What sinks attempts is generally the way it was presented and the lender it was presented to.

Here's the thing worth internalising before you ever fill in an application: a credit assessor is answering one question, and it isn't how much do you earn? It's will this income still be here in three years? Salaried applicants answer that with a single employment contract. Locums answer it with a stack of documents that, read without context, look like someone who changed jobs six times.

That gap is a presentation problem. Presentation problems are fixable.

What are the four things that actually trip the file up?

Multiple payers. Agency shifts, direct hospital bookings and practice sessions can all land in the same month from different sources. Individually, none of them services the loan. Collectively they do, but only if the assessor adds them up rather than picking the biggest one.

Gaps that aren't gaps. Annual leave, exam study, conference weeks, the fortnight between contracts. Each shows as a zero-income period. If a lender averages your earnings over a short window that happens to include one, the resulting figure can be dramatically below what you actually earn.

Rotation churn. A registrar changing hospital and term every few months looks, on a bare employment history, like chronic instability. It's the opposite: it's a structured training pathway with a defined endpoint.

Mixed classification. Some locum work is PAYG through an agency. Some is invoiced under your own ABN. These sit in completely different sections of a lender's policy manual, and plenty of doctors are doing both simultaneously without realising the distinction matters.

PAYG or ABN? Find out before you apply

This single question changes which lenders are viable, so settle it first.

If your agency pays you PAYG, you have payslips and tax withheld, and most lenders can assess you under standard casual or contract income rules. Many average the last twelve months. Some apply a discount to variable income on top of that, which is exactly the sort of policy detail worth knowing before submitting, not after.

If you invoice under an ABN, credit policy treats you as self-employed, no matter how clinical the work is. That generally means tax returns, notices of assessment and a longer trading history. The mechanics are the same as for any other professional in that position, and the way how lenders assess self-employed income works is worth understanding even if you only bill a portion of your work this way. If you're running both streams, the classification logic behind contractor and ABN home loans is the same one that will be applied to your file.

Prove continuity, not permanence

This is the mental reframe that wins locum applications. You will never be able to prove permanence, that's the nature of the work. You can absolutely prove continuity of income, which is what the policy actually requires.

What does that: current AHPRA registration. A twelve-month-plus income window rather than a recent snapshot, so leave and contract gaps wash out. A schedule of completed placements with dates. An agency letter confirming ongoing shift availability, which is frequently worth more than any individual payslip. Six to twelve months of statements showing the income arriving consistently.

For registrars, the strongest document in the file is often the one people leave out: the college training program details and rotation schedule. Attach those and a "six employers in two years" history reads instead as a doctor two years into an accredited pathway with a known completion date. Same facts, entirely different credit decision.

Does the medical LMI waiver still apply?

Frequently, yes; and this is the part locums most often assume they've forfeited.

The waiver policies that let eligible medical professionals borrow at high loan-to-value ratios without paying lenders mortgage insurance are keyed to profession and current AHPRA registration, not to employment type. As a general guide, doctors and dentists can access waiver policies up to around 95% of the property value with some lenders, while nurses, midwives and many allied health professions are typically capped nearer 90%.

Being a locum doesn't automatically disqualify you. What varies is how far an individual lender will stretch on the deposit side once the income is variable; some will hold a locum below their published maximum. That's a lender-selection question, and it's the reason medical professional home loans are worth mapping out properly rather than applying to whoever your colleague used.

The two rules that set your ceiling

Regardless of profession, two settings cap what any lender can advance.

The first is the serviceability buffer. Lenders must test your repayments at roughly three percentage points above the rate you'd actually pay. A loan priced in the low sixes is assessed as though it were in the low nines. This is why the number a lender gives you always lands well below what the real repayment would suggest you could handle.

The second is the debt-to-income cap. Since 1 February 2026, APRA has limited high debt-to-income lending, with six times gross income the practical threshold most lenders now work to. For variable income, the figure entering the top of that ratio is the lender's assessed income after averaging and any discount - not your best month annualised. It's the single biggest reason two lenders can quote the same locum wildly different maximums.

A borrowing power calculator will give you a rough range to work with, but treat it as an indication only. The real number comes out of a specific lender's calculator run against your actual documents.

And one more thing: HECS

Almost every doctor carries a HELP balance, and it does reduce capacity, because the compulsory repayment comes off assessable income before servicing is calculated. On a registrar salary that bite is meaningful.

Two useful nuances. The impact is driven by the repayment rate, not the size of the balance. Aggressively paying it down isn't always the fastest route to a larger loan. And if you're within a year of a significant pay step, timing matters: getting the structure right before the step and reviewing after it usually beats simply waiting.

The mistake that costs the most

The expensive move is a well-intentioned application to a single lender whose averaging policy doesn't suit variable income. It lands on a figure that doesn't reflect reality and either declines you or approves you far below capacity, and the enquiry sits on your credit file for the next lender to see.

Match the doctor to the policy first. Submit second. On locum and rotating-contract files, that order is most of the outcome.
