If you are trying to buy a home on a casual or part-time income, you have probably noticed the biggest frustration. Plenty of lenders say “it depends”, but few explain what they actually mean.
The good news is that a home loan on a non-standard work pattern is often possible. The catch is that lenders usually want clearer evidence that your income is reliable and likely to continue, because casual hours can change and part-time roles can vary by industry.
In this guide, we will walk you through how Australian lender policies commonly assess casual and part-time income, what documents usually matter most, and how a mortgage broker for unusual employment loans can help you present your application in a way that aligns with lender rules. Along the way, we will also explain why your borrowing capacity can look different from one lender to another.
That sets the scene. Next, let’s get specific about what lenders mean by “casual” and “part-time”.
Casual vs part-time, what lenders are actually assessing
Before any calculator comes out, lenders generally focus on one thing, the quality of the income, not just the label on your contract, but how consistent and ongoing the income appears.
Part-time income
Part-time employment is usually viewed as more predictable than casual employment because the hours are often set or at least consistent. Many lenders will treat part-time base income similarly to full-time income, provided it is ongoing and supported by payslips and employment details.
Casual income
Casual income is usually assessed more cautiously for a casual employment home loan because the hours are not guaranteed. Some lenders may still use casual income, but they often want evidence that your earnings are consistent over time, and that you are likely to keep working at a similar level.
That’s the classification piece. Next, let’s look at why lenders can feel stricter now than they did years ago.
Why serviceability can be harder on variable hours
Even if your income looks strong, lenders must still assess whether you could manage repayments if rates rise.
APRA’s guidance requires banks to apply a minimum 3% serviceability buffer above the loan interest rate when testing affordability. In plain terms, lenders assess your ability to repay at a higher rate than you will actually pay, to allow for rate rises and changes in income or expenses.
For casual and part-time borrowers, this can matter because:
- your assessed income may be “shaded” or averaged
- your expenses may be tested in more detail if spending is variable
- the buffer reduces borrowing power even when your deposit is strong
That’s the “why” behind the rules. Next, we will break down how lenders usually calculate income for these employment types.
How lenders usually calculate casual and part-time income
There is no single standard method across all lenders. However, many lender policies tend to follow a few common patterns.
1) Base pay vs variable pay
Lenders often prefer income that is:
- contracted, ongoing, and consistent, and
- easy to verify from payslips and employment details
Where casual workers earn penalties, loadings, or overtime, some lenders may average those amounts over a period rather than taking the latest week at face value.
2) “Averaging” is common for casual income
For casual income, lenders may look at your year-to-date income on payslips and/or your income history over a longer period to form an average. Some lenders may want a longer track record if your hours move around a lot.
Some major lenders publicly acknowledge that casual and irregular income can be assessed, and their guidance focuses on showing stability and being able to explain fluctuations.
3) Part-time can still be assessed as stable
Part-time income is often simpler to assess when:
- it is ongoing
- you have a consistent pattern of earnings
- your role is not in a short-term probation scenario (policy varies)
That’s how income is often interpreted. Next, let’s cover the evidence lenders usually want, because documentation is where many applications succeed or fail.
The documents that usually matter most
If you want a lender to use your casual or part-time income, you typically need to make it easy for them to verify and “trust” the numbers.
Many lenders commonly ask for recent payslips, and may also want group certificates or ATO income summaries to support consistency over time.
Here is what is often helpful, depending on your situation.
Core documents lenders commonly request
- Recent payslips (showing year-to-date figures)
- Employment details (role, start date, basis of employment)
- Bank statements (to confirm salary credits)
- ATO income statement / PAYG summary history (where relevant)
- Evidence of deposit and savings conduct
Situations that may require extra clarity
- You recently changed employers but stayed in the same industry
- Your hours vary seasonally
- Your income includes allowances, penalties, or multiple employers
- You have gaps in your employment history
This is where a mortgage broker in Sydney can help guide the process. At Unconditional Finance, we often map your income evidence to the lenders most likely to accept that style of income assessment, rather than forcing your application into a policy that does not fit.
That’s the paperwork side. Next, let’s talk about the most common lender “speed bumps” for casual and part-time borrowers.
Common policy hurdles and how they are handled
Even when income evidence is strong, lenders still apply policy filters that can affect how much of that income they are willing to use. Understanding these common hurdles helps explain why outcomes can differ between lenders.
Short employment history
Some lenders may be comfortable with a shorter history if you have strong industry continuity, while others may want longer evidence of consistent earnings. This is one of the biggest reasons borrowing capacity can vary from lender to lender.
Probation periods
Some lenders may lend during probation, others may not, and some may require extra conditions. This can apply to both part-time and casual work, depending on your contract structure.
Multiple jobs
If you have two part-time jobs, or casual work plus a second job, lenders may:
- accept both, or
- accept one as primary and “shade” the other, or
- require a longer history for the secondary role
Taken together, these factors explain why income that looks strong on paper may still be assessed conservatively under certain lender policies.
Income that includes loadings and penalties
Casual loadings and shift penalties can help your real-world cash flow, but lender calculators may treat them differently. Some may average them. Some may want to see a longer run of consistent payments.
That’s the hurdles. Next, we’ll cover what lenders look for beyond income, because approval is never only about your payslips.
What lenders check besides your income
Even with perfect income documents, your finance approval can still turn on the broader risk picture.
Expenses and living costs
Lenders typically review your declared expenses and may compare them to transaction history. If your spending changes month to month, they may ask for context.
Existing debts
Credit cards, personal loans, HECS HELP, and car finance can all impact borrowing capacity. Even unused credit card limits can reduce serviceability.
Savings conduct and buffers
Regular savings, stable account conduct, and having some funds left after purchase (depending on the lender) can support your application, especially when income is variable.
The serviceability buffer
Even if you qualify today, lenders must assess affordability with the 3% buffer applied, which can reduce the amount you can borrow compared to what your budget suggests.
That’s the full assessment lens. Next, let’s make this practical, what can you do before applying that is actually helpful and not just generic advice.
Practical steps that can improve how your application is assessed
These are not “approval hacks”. They are preparation steps that often make your file easier to assess under the lender policy.
Keep your income evidence clean and consistent
- Avoid missing payslips or unclear payroll descriptions where possible
- Keep bank salary credits easy to match to payslips
- If you have variable hours, having a longer evidence trail can help some lenders
Reduce avoidable serviceability drains
- Review credit card limits, unused limits can still reduce borrowing power
- Avoid taking on new debt before and during assessment
- Keep repayments and bills paid on time
Be ready to explain changes
If your hours jumped recently, or dropped temporarily, lenders may ask why. A clear, truthful explanation supported by documents can prevent delays.
That’s the prep work. Next, let’s look at the big question many borrowers ask, “is casual income treated differently depending on the industry?”
Does your industry matter for casual or part-time borrowing?
Sometimes, yes, because lenders may consider how likely your income is to continue.
For example:
- Some industries have predictable casual patterns (healthcare, education relief pools, hospitality with stable rosters).
- Other industries can be more seasonal or project-based.
This does not mean one industry is “good” and another is “bad”. It simply means evidence expectations can change depending on how variable the work is.
NAB’s consumer guidance on casual and irregular income also reflects this idea of showing the lender stability and context around irregular earnings.
That’s the industry nuance. Next, we’ll cover how pre-approval typically works when your income is not a standard full-time salary.
Pre-approval with casual or part-time income, what to expect
A home loan pre-approval with casual income or part-time income can still be possible, but you may find:
- the lender asks for more history or clearer income verification upfront
- the assessed income is averaged rather than based on a recent high-paying period
- conditions can be tighter if the lender needs additional confirmation before formal approval
This is one reason many borrowers use a mortgage broker when exploring non-standard income home loans. The goal is not to “push” a lender. It is to match your situation to lender rules, and submit an application that is consistent, complete, and verifiable.
That’s how the process often plays out. Next, let’s address a few fast “myth checks” we hear all the time.
Quick myth checks
There is a lot of misinformation around casual and part-time income home loans. These clarifications help reset expectations before you rely on assumptions that may not hold up under lender assessment.
“Casual workers can’t get a home loan”
Some lenders may accept casual income, provided you can show consistency and meet serviceability, deposit, and credit criteria.
“Part-time income is always discounted”
Not always. Some lenders may use part-time base income fully if it is ongoing and verifiable, but policies differ.
“If one bank says no, they all will”
Not necessarily. Lender policies can vary, especially for income types that are assessed with discretion.
That clears up the noise. Next, we’ll wrap this into a realistic next step if you want to move forward.
A realistic way to move forward without guessing
If you are paid casually or work part-time and you want to know what may be possible, the most useful next step is usually to compare lender policy treatment of your income type before you apply, not after a decline.
If you would like to see what options may be available for your situation, Unconditional Finance can help you compare lender policies, check what documents you will likely need, and guide you through the next steps in a clear, lender-aligned way.

Frequently Asked Questions (FAQs)
Some lenders may consider it, but they often want evidence that your income is consistent and likely to continue. If you are new to the role, lenders may look more closely at your prior work history in the same industry and how steady your hours and pays are so far. Eligibility can vary depending on the lender’s policy.
Some lenders may include certain ongoing Centrelink payments, while others may exclude them or apply limits depending on the payment type and your overall situation. It usually depends on whether the payment is considered stable and how long it is expected to continue. You may need to provide supporting statements and confirmation notes where relevant.
It could. A job change can trigger a reassessment, especially if your income structure, hours, or industry changes. Some lenders may still proceed if the new role is similar and your income remains consistent, but policies and evidence requirements vary.
Some lenders may consider multiple income sources, but they often apply stricter verification and may require a longer track record for secondary or gig income. They may also average income over time rather than using your most recent higher weeks. Lending criteria and documentation requirements can change depending on the lender.
Yes, because lender treatment of variable income can differ, even when your overall earnings are healthy. A broker such as Unconditional Finance may help you compare policy approaches and package your evidence clearly so the lender can assess it consistently. This does not guarantee approval, but it can reduce guesswork and avoid avoidable policy mismatches.
