One Doc Home Loans for Locum Doctors and Short-Contract Specialists
How Lenders Assess Locum and Short-Contract Medical Income
Locum doctors and short-contract specialists face a paradox: high income, unstable employment pattern. Lenders see the income but worry the gaps between contracts signal risk. The assessment hinges on whether lenders trust your professional credentials and income consistency.
Here's what happens inside the lender's assessment: they examine your ABN history, whether your income is smoothed across contract gaps, and whether your One Doc application is backed by solid professional evidence. Unlike permanent staff, locum income is variable month-to-month. Lenders need to see that you've built a buffer—either through savings, continuous contract flow, or explicit income averaging from your accountant.
The key difference between locum and permanent medical income is how lenders calculate your serviceability. Permanent staff show linear salary history. Locums show contract start/end dates, gaps, and variable weekly rates. The lender needs to understand: across the last 2 years, what's your average monthly take-home after gaps?
| Income Pattern | Lender View | Approval Likelihood |
|---|---|---|
| Continuous contracts, minimal gaps | Stable. Proves ongoing demand for your skills. | Strong |
| Contracts with short, predictable gaps, regular income | Normal. Expected in locum work. Needs income smoothing. | Good (with accountant letter) |
| Long gaps (1–2 months between contracts) | Risky. Suggests sporadic work. Raises serviceability questions. | Challenging |
| First contract or under 18 months ABN history | Too new. Insufficient track record. Most lenders reject. | Unlikely |
In March 2026, the RBA has continued rate adjustments with back-to-back hikes that split the board on voting. This tighter rate environment means lenders are stress-testing serviceability harder than ever. Your capacity to service a mortgage through contract gaps and income variability is now under closer scrutiny.
The Accountant's Letter for Variable Medical Income
Your accountant's letter is the single most important proof in a locum or short-contract One Doc application. It's not a tax document—it's a professional certification that your income is real, consistent, and repeatable across contract cycles.
Lenders expect the letter to address these specific points:
| What the Letter Must Cover | Why It Matters |
|---|---|
| ABN age and continuous operation How long has your ABN been active? |
Lenders want minimum 2 years. Newer ABNs carry higher assessment risk, even for experienced doctors. |
| Income trend (year-on-year) Is your net income growing, stable, or declining? |
Growth or stability signals ongoing demand. Decline is a red flag, especially in 2026 when medical work is tightening. |
| Average monthly or annual net income What's your typical take-home after contracts, gaps, and expenses? |
This is the figure lenders use for serviceability. Must account for contract gaps explicitly. |
| Income smoothing methodology How do you calculate income across variable contract cycles? |
Lenders need clarity: are you averaging across a rolling 12-month period? Smoothing contract payments against gaps? This justifies why your variable income should be trusted. |
| Nature of contracts Are contract lengths predictable? Are gaps foreseeable or irregular? |
Predictable contract cycles and known gaps are easier for lenders to underwrite. Random or lengthening gaps suggest demand is falling. |
A weak accountant's letter stalls the application immediately. If your letter is vague about income averaging, doesn't address contract gaps, or fails to justify why variable income is reliable, lenders will request clarification or reject outright. In 2026, the standard is higher: your letter must be detailed, specific, and professionally signed.
If you're thinking about a One Doc application, brief your accountant now. Tell them you're applying for a home loan and need a detailed letter covering ABN history, net income trend, income-smoothing method, and contract structure. The more specific, the faster the lender moves.
AHPRA Registration and What It Signals to Lenders
Your AHPRA registration status is your professional credential—lenders treat it as proof that you're a legitimate medical professional. For locums especially, it's the first signal that your income is real.
Lenders check your AHPRA standing for two reasons. First, it confirms you're legally registered to practice and that there are no disciplinary flags or restrictions that might affect your earning capacity. Second, it proves you're held to a professional standard and that your income claims can be backed by a regulated body.
What matters to lenders about your AHPRA status:
- Current registration: If your registration is expired or lapsed, lenders may pause the application until you renew. Some lenders require documentation showing renewal in progress.
- Full registration vs limited registration: Full registration is standard and preferred. Limited registration (e.g., for overseas-trained doctors in their first 10 years) is still acceptable but may trigger more questions about contract stability and income.
- No adverse findings: If your registration has conditions, restrictions, or pending investigations, disclosure is mandatory. Some lenders will still proceed; others won't. This is one of the few areas where lender appetite varies sharply.
- Professional indemnity insurance: Lenders often ask whether you carry PI insurance (most locums do). If you don't, it's a red flag—lenders worry that uninsured medical professionals may be higher risk or less professional in their approach.
In summary: your AHPRA registration is what separates a locum doctor from a gig worker in a lender's eyes. Keep it current, carry PI insurance, and disclose any conditions upfront. Your registration is proof that your income is legitimate. Check your eligibility to see how your registration status affects your borrowing capacity.
When Locum Income Alone Isn't Enough—Structuring Around the Gap
Some locums and short-contract doctors have strong enough income to qualify on their own. Others find that variable income limits their borrowing capacity even if their annual take-home is solid. You have three structural options.
The first option is One Doc on locum income only. If your ABN is 2+ years old, your income is smoothed, and your accountant's letter is detailed, lenders will assess you as a self-employed professional. No co-borrower needed. This is the cleanest path if your income is genuinely sufficient.
The second option is co-borrowing with a partner who has PAYG income. If you have a spouse or partner earning salary, you can blend both incomes. The PAYG income adds stability and may lift your total borrowing capacity. However, lenders often discount locum income by 15–25% when it's blended with PAYG—so co-borrowing doesn't always increase your power as much as you'd expect. You need to model this with a broker before committing to the structure.
The third option is using a guarantor. If your locum income is strong enough to service the loan but you want additional security or flexibility, a guarantor (partner, parent, or trusted professional) can back the loan without being a co-borrower. This keeps your income assessment separate and focused, while the guarantor provides a safety net. Guarantors must have assets, income, or financial standing that's credible to the lender.
✓ Stronger Locum Application
- 2+ years continuous ABN history
- Consistent contract flow with predictable gaps
- Detailed accountant's letter with income smoothing
- Current AHPRA registration, no restrictions
- PI insurance in place
- Growing or stable year-on-year income
✗ Weaker Locum Application
- ABN under 18 months old
- Long or unpredictable gaps between contracts
- Vague accountant's letter or no letter
- AHPRA registration with restrictions
- No PI insurance
- Declining year-on-year income
Which structure is best? That depends on your specific situation. If your locum income is strong, consistent, and well-documented, One Doc on your own income is fastest and gives you full control. If you have doubts, or if co-borrowing with a partner lifts your capacity significantly, model both scenarios with a specialist broker familiar with medical lending.

Frequently Asked Questions
Yes. One Doc loans don't require permanent employment—they're designed for self-employed and variable-income earners. If you have an ABN, consistent contract work, and a solid accountant's letter, you can qualify. What you can't do is apply with less than 18 months of ABN history (most lenders require 2 years). Permanent contracts help, but they're not mandatory. The lender wants proof of income consistency and professional legitimacy, which your One Doc application provides.
Lenders use one of two methods. First, they look at your last 2 years of tax returns and calculate average annual income, then divide by 12 to get a monthly figure. This method assumes contract flow will continue. Second, they ask your accountant to provide a smoothed income figure in their letter—explicit justification for why variable income is reliable. Some lenders apply a discount to locum income (10–20%) to account for contract risk. Others accept it at face value if your ABN history is strong and gaps are predictable. Ask a broker which method your target lender uses—it affects your borrowing capacity.
AHPRA registration status matters to some lenders more than others. Full registration is always preferred. Limited registration (common for overseas-trained doctors or those in the first 10 years of practice) is still acceptable but may trigger additional questions about income stability and future earning capacity. If your registration has conditions or restrictions (e.g., you're required to work under supervision), you must disclose this. Some lenders will proceed; others may decline or impose conditions. Check with your broker about lender appetite for limited registration before you apply.
Working across multiple facilities is normal for locums and doesn't hurt your application—it actually proves your skills are in demand. However, you need to document it clearly. Your ABN, tax returns, and accountant's letter should show all sources of income. If you're doing private work, hospital contracts, and agency work, lenders want to see them bundled into one net income figure. Asset finance and finance lease for vehicles can be handled separately. The key is clarity: lenders should understand where your income comes from and that it's diversified across stable sources, not dependent on a single hospital or contract.
If your ABN is under 18 months old, yes, wait. Most lenders won't assess seriously. If you're between 18 and 24 months, you can apply, but approval odds are lower and lenders will scrutinise your contract pipeline closely. If you're 2+ years in with consistent income and smooth contracts, apply now. The time cost of waiting outweighs the marginal benefit of an extra 3–6 months of history. Lenders care more about consistency and income smoothing than absolute ABN age. Get a broker to assess your current eligibility—it's free and gives you a realistic timeline.
