Many Australians earn through ABN work, side hustles or sole trading, which makes their income look irregular on paper. This guide explains how lenders assess that income and what you can provide to strengthen your home loan application.
Roughly two in three Australian businesses are run by sole operators, and survey data suggests that one quarter to one third of Australian adults currently have a side hustle or similar extra income stream. And the one thing each of these individuals have in common is irregular business income.
Australians who work under an ABN as a freelancer, sole trader, contractor or solopreneur don’t typically have traditional payslips to prove their income to potential lenders. Yet, they still want to own homes. And they should! There are many lenders that are open to lending to these types of borrowers. However, they still need to find a way to prove their income.
Understanding how lenders assess irregular income (from ABN work like side hustles or self-employment) is the first step. The next is documenting it properly.
Home lenders evaluate mortgage applications based on risk, and the biggest question they’re trying to answer is simple – can you comfortably repay the loan? Before they bring you on as a borrower, they need to be able to see that you can do just that.
When you don’t have the typical paperwork to supply to a home lender, it can feel like the process is stacked against you before you even begin. How do you show a lender that you’re a good bet for a home loan, when you can’t even show what you earn.
Another challenge is that self-employed and casual earners often have ‘lumpy’ income – this is income that tends to fluctuate month to month. One quarter might bring strong revenue while the next is leaner. This variability can raise questions, and lead lenders to scrutinise self-employed applications more closely to ensure your income is stable enough.
But just because your income is irregular, doesn’t mean that getting a home loan is impossible. With the right documentation and presentation, not traditional earners can absolutely get home loan approval.

When you don’t have regular payslips, lenders turn to other signals of financial stability. Here’s what lenders are looking for:
Because your income isn’t a regular wage, lenders often ask for more comprehensive paperwork to prove that your business, and income, is stable. Some of the documents they may ask for include:
Depending on the lender and loan type, they might ask you to supply all or just some of these.
For self-employed borrowers, or borrowers with irregular income, there are generally two pathways to getting a home loan – full doc or low/alt doc loans.
Full doc loans are the most straightforward from a lender risk perspective. But they’re also the most paperwork heavy. These are standard mortgages or loans, and so they require all the same documents to fully verify your income and ability to repay. So typically you’ll be required to provide most of the documents described above, including:
Though all the paperwork can be a downside to these types of loans, because they give lenders a full financial picture, you’re usually able to get a better deal. For example, full doc loans usually come with the best interest rates and the most favourable terms.
These loans are designed for people who struggle to produce all the paperwork required for a full-doc loan. This is usually true for newer ABN holders, freelancers or businesses with fluctuating income. Instead of tax returns and full financials, lenders may accept:
Because the documentation is less comprehensive, lenders view these loans as higher risk. And because of that they often come with higher interest rates, stricter borrowing limits and a more conservative income assessment.
However, low-doc lending still works well, especially if you’re organised with your financial records, maintain a clean credit history and can provide evidence of ongoing cash flow. And it’s a great way to get your home loan across the line when documentation is otherwise challenging.
If you have irregular or ABN-based income and are thinking about applying for a home loan, these actions can help you present a stronger application.
If you’re a contractor, freelancer, sole trader or side-hustler, don’t assume that you’re shut out from borrowing. Lenders are more willing to consider non-traditional income, but they need evidence that it’s stable, sustainable and well-documented.
