Locums & Contractors: Make Irregular Income Bankable for a Home Loan

Irregular income doesn’t disqualify you from getting a strong home loan.

If you’re a locum doctor, contractor engineer, IT consultant, allied health professional, or any kind of independent contractor, banks will lend – but only if your numbers tell a clear, stable story. The key is to translate lumpy, project‑based income into something that looks predictable and bankable.

This guide shows you how, with a focus on what you can do in the next 7 days to be genuinely application‑ready.

1. How banks really see locums and contractors

For credit teams, your job title matters less than one question: “Can this person reliably make repayments over the next 25–30 years, even if things get choppy?”

Because your income is irregular, banks generally:

1. Treat you as self‑employed, even if you get PAYG summaries from multiple agencies.
2. Average income over 1–2 years, and often use the lower figure if income is volatile.
3. Apply at least a 3% serviceability buffer above the current rate (APRA guideline).
4. Shade or ignore income they see as short‑term, unusual or poorly documented.

They are not trying to punish you for being flexible – they are trying to avoid approving a loan that would push you into mortgage stress if a contract ends or hours drop.

Roy Morgan research in 2026 shows mortgage stress at an 18‑year high, with roughly one‑third of borrowers ‘At Risk’. That makes banks more conservative with anyone whose pay is less predictable.

Bottom line: locums and contractors can often qualify for strong loans, but you must do more work than a simple PAYG employee to present your income.

2. What counts as “bankable income” for locums & contractors?

“Bankable” income is income a lender is prepared to rely on under its credit policy.

For locums and contractors, lenders usually group income into four buckets.

2.1 Core income (the backbone of your borrowing power)

This is what most lenders want to build your borrowing capacity from:

• Locum shifts or consulting days with at least 12–24 months’ history
• Hourly/day‑rate contracting with rolling contracts in the same field
• Private practice billings where you control your hours and pricing
• Regular part‑time PAYG work alongside locum/contracting

They’ll look for:

• A stable or upward trend over 2 years
• Reasonable explanation for any big dips
• Evidence that work is likely to continue (market demand, repeat clients, agency letters)

2.2 Supplementary income (used but often shaded)

This income may be counted, but often at a discount:

• Overtime and extra shifts beyond your usual pattern
• Short‑term project work or one‑off contracts
• Teaching, supervision, consulting or speaking gigs
• Side hustles and start‑ups with less than 2 years’ history

Lenders might only count 50–80% of these figures, or ignore them if they’re small or inconsistent.

For a deeper dive into these patterns across multiple roles, see "Turning Side Hustles, Start‑Ups and ESOPs Into Bankable Income".

2.3 Non‑bankable income (nice for you, invisible to credit)

Despite helping real‑world cashflow, many lenders ignore:

• Cash jobs with no invoices or bank trail
• Early‑stage business income without tax returns
• Irregular crypto or trading gains
• Sporadic family transfers or informal support

You can’t rely on these to boost borrowing capacity. They’re still useful for buffers, just not for the application itself.

2.4 Negative adjustments (what gets taken off)

Even high‑earning locums can see their usable income reduced for:

• HECS/HELP and other salary deductions
• Business expenses that run through personal accounts
• Existing loans and credit cards (limits, not just balances)
• Dependants and high living costs – lenders test against HEM benchmarks

This is why the same income can produce very different borrowing capacity for different people.

For complex professional income mixes (common for doctors, lawyers and consultants), there’s a detailed worked approach in "Turning Complex Professional Income Into Borrowing Power In Sydney’s East".

3. Typical locum and contractor borrower profiles (and how banks read them)

Let’s look at a few common patterns.

3.1 Locum doctor or allied health professional

Profile:

• 34‑year‑old GP locum across three clinics
• Mix of hourly and percentage‑of‑billings contracts
• Income last year: $320,000 gross; prior year: $260,000
• Has an ABN, invoices agencies and clinics

How a bank might read this:

• Treat as self‑employed, requiring 2 years of tax returns
• Start with taxable income, not gross billings
• Possibly average the two years: ($260k + $320k) ÷ 2 = $290k
• If latest year clearly sustainable and higher, some lenders might use $320k

The same pattern applies to locum anaesthetists, radiologists, pharmacists, dentists and allied health professionals.

3.2 IT contractor or engineer on rolling contracts

Profile:

• 41‑year‑old contractor on 6‑month rolling contracts
• Day rate $1,200 + GST
• Works through a Pty Ltd, pays themselves a salary and some dividends
• 3–4 week gap between some contracts over the last 2 years

How a bank might read this:

• Look at company financials + personal tax returns
• Focus on total cash available to the individual (salary + dividends)
• Expect explanation for each gap – was it voluntary? Industry‑wide slowdown?
• Tilt toward a conservative average to reflect contract risk

3.3 Consultant with mixed PAYG + ABN income

Profile:

• 37‑year‑old management consultant
• 3 days/week PAYG for a firm; 2 days/week under an ABN for startup clients
• PAYG income $150,000; ABN net $70,000 in the latest year

How a bank might read this:

• PAYG income usually accepted easily with payslips and a group certificate
• ABN income assessed like a small business: tax returns, profit & loss, bank statements
• If ABN income is new, lender might heavily shade it or require two years’ history

The pattern is similar to many discussed in "Home Loans on Irregular Mining, Construction and FIFO Income": good money, but the structure matters.

4. The one‑week plan: make your income bank‑ready

In a perfect world you’d optimise this over 6–12 months. In reality, many locums and contractors decide to buy or refinance quickly.

Here’s what you can realistically do this week.

4.1 Day 1–2: Get your documents in order

You want to make it dead simple for a credit assessor to see your income story.

Core documents:

• Last two years’ personal tax returns and ATO notices of assessment
• Last two years’ business or trust tax returns (if relevant)
• 6–12 months of personal bank statements
• 6–12 months of business account statements
• Current contracts, rosters or engagement letters
• Any PAYG payslips and year‑to‑date summaries

Nice‑to‑have extras:

• Brief CV showing industry experience and years practising
• Letter from agency or practice manager about work availability
• Explanation notes for any significant gaps in work

If your books are messy, practical fixes like those in "Turn Chaotic Self‑Employed Accounts Into a Bank‑Ready Story Fast" can help you clean the worst up quickly.

4.2 Day 3: Clean your bank statements

Underwriters will comb through your accounts. You want them to see stable, sensible behaviour.

Quick wins:

• Stop transferring money in circles between accounts – keep it simple
• Minimise obviously discretionary spending for at least 3–6 months before applying
• Avoid overdrawn accounts and dishonours – they’re a red flag
• Make sure tax instalments are up‑to‑date (it signals discipline)

You don’t need to live like a monk, but you do want your statements to look boring.

4.3 Day 4: Build a one‑page income story

Write a simple summary that explains:

• What you do and in which speciality/industry
• How you get paid (day rate, billings %, consulting fees)
• How long you’ve been doing this kind of work
• Why any income dips or gaps occurred – holidays, maternity/paternity leave, study, COVID, industry change

This isn’t a formal document, but it helps your broker position your file. It’s the narrative spine that turns raw numbers into a story.

4.4 Day 5–7: Align tax, cashflow and borrowing goals

High‑income locums often get tripped up here.

Your accountant might be doing a great job minimising tax, but that can mean:

• Pushing income into companies or trusts
• Maximising deductions that lower taxable income on paper
• Taking income as irregular dividends or distributions

Banks lend against taxable income (and sometimes add‑backs). If everything is pushed down, your borrowing power can shrink at the exact moment you want to buy.

The solution is coordinated planning. As we’ve covered in "Structuring Income from Your Practice to Maximise Borrowing Power", your accountant and broker should work off a shared cashflow model so tax planning and borrowing capacity don’t fight each other.

5. How lender policies differ for locums & contractors

Not all lenders treat locum or contract income the same. The differences can be worth hundreds of thousands of dollars in borrowing capacity.

5.1 Key policy levers

Common points of divergence:

• Minimum history: some want 2 years; others accept 12 months in the same field
• Use of latest year: some use the latest year if clearly sustainable; others average two years
• Treatment of gaps: some are comfortable with short, explained gaps; others are rigid
• Professional recognition: some offer more flexible policies for certain professions (e.g. medical, legal, accounting, engineering)
• Alt‑doc options: some allow bank statements or accountant letters instead of full tax returns, at the cost of higher rates and/or fees

5.2 Example: income averaging in practice

Assume you’re a contractor with:

• Year 1 taxable income: $180,000
• Year 2 taxable income: $240,000

Two lenders might do this:

That $30,000 difference can translate into a significantly higher or lower borrowing capacity.

5.3 Example: day‑rate contractor assessment

A lender might convert a day rate into an annual income like this:

• Day rate: $1,200
• Days per week counted: 5
• Weeks per year counted: 46 (allowing for gaps, holidays etc.)

Annualised income = $1,200 × 5 × 46 = $276,000

Some lenders might only use 44 weeks; others will use your actual contract terms if you can evidence continuous work.
