Your income determines how much you can borrow, but proving that income to a lender's satisfaction is where most applications slow down or fail.
Lenders don't just check that you earn enough. They verify the type of income you receive, how stable it is, and whether they can rely on it continuing for the life of the loan. The same annual figure can be treated very differently depending on whether it comes from a permanent salary, shift allowances, or self-employment.
How Lenders Calculate Your Borrowing Power
Lenders assess your borrowing capacity by comparing your verified income against your living expenses and existing debts. Most lenders use a debt-to-income ratio, which compares your total monthly debt repayments to your gross monthly income. While no legislated DTI limit exists in Australia, many lenders cap lending at six times your annual income, and some use lower thresholds depending on their internal risk settings.
Consider a buyer in Ringwood earning $95,000 annually with a car loan repayment of $450 per month and a credit card limit of $10,000. Even if the card is paid off in full each month, the lender will calculate a minimum repayment based on the limit, usually around 3% of the balance or $300. Combined with the car loan, that's $750 in monthly commitments before the home loan is added. The lender then applies a serviceability buffer, typically 3%, on top of the current variable rate to stress-test whether you could afford repayments if rates rose. This calculation directly affects your borrowing capacity.
Permanent Employment and PAYG Income
Permanent full-time or part-time employment with a consistent salary is the most straightforward income type for lenders to verify. You'll need recent payslips, typically the two most recent, and a letter of employment or contract showing your role, salary, and employment start date. If you've been in the role for less than six months, some lenders may ask for additional documentation or apply a higher interest rate.
Shift allowances, overtime, and bonuses are treated differently depending on consistency. If you've received the same allowance for at least three months and it's a regular part of your roster, most lenders will include it. Sporadic overtime or one-off bonuses are usually excluded unless you can demonstrate a pattern over 12 months or more, supported by payslips and a letter from your employer.
Self-Employment and ABN Income
If you're self-employed, lenders typically require two years of tax returns and Notices of Assessment from the ATO. They use your taxable income, not your turnover, to assess what you can borrow. This means deductions that reduce your tax liability also reduce your borrowing capacity.
In our experience, this is where many self-employed buyers in Ringwood, particularly those running small businesses along Maroondah Highway or in the Eastland precinct, encounter unexpected limits. A buyer earning $120,000 in turnover but claiming $40,000 in deductions will be assessed on $80,000 of income. Some lenders allow add-backs for certain non-cash deductions like depreciation, but policies vary widely between lenders. Working with a broker who knows which lenders offer the most favourable treatment for self-employed applicants can meaningfully increase your borrowing capacity.

Casual and Contract Income
Casual and contract workers can absolutely qualify for a home loan, but the documentation burden is higher. Lenders want to see at least six months of consistent income, though 12 months is preferred. You'll need payslips covering that period, a letter from your employer confirming ongoing work, and often a contract or roster showing future shifts.
Some lenders will assess the average of your income over the period, while others take a more conservative approach and use the lowest month. If your income fluctuates significantly between months, choosing the right lender becomes critical. A buyer working casual retail shifts in Eastland earning between $3,200 and $4,800 per month might be assessed on $3,200 by one lender and $4,000 by another, which translates to a borrowing difference of tens of thousands of dollars.
Probationary Periods and Recent Job Changes
Changing jobs doesn't automatically disqualify you, but it does require explanation. If you've moved to a new employer in the same industry with the same or higher income, most lenders will accept your application once probation is complete. Some lenders will approve during probation if you can provide an unconditional offer letter and a strong employment history in the same field.
Moving industries or taking a pay cut raises more questions. Lenders may ask for a statutory declaration explaining the change and evidence that your new income is stable. If you've recently returned to work after a career break, expect to provide at least three months of payslips and a letter confirming your ongoing employment.
Income From Rental Properties and Investments
If you own an investment property, lenders will include the rental income in their assessment, but not at 100%. Most lenders use 80% of the gross rent to account for vacancy periods and maintenance costs. If you're purchasing another property as an investment loan, the rent from the new property can sometimes be used to help service that loan, depending on the lender and your overall financial position.
Dividend income and distributions from trusts are assessed based on your tax return and Notice of Assessment. Lenders typically average this income over two years unless you can demonstrate it's ongoing and reliable.
Centrelink and Government Payments
Some lenders will accept certain Centrelink payments as part of your income, including Family Tax Benefit, Carer Payment, and the Disability Support Pension. Parental Leave Pay is generally not accepted because it's temporary. The portion of income from government payments that lenders will use varies, with some lenders accepting up to 100% and others capping it at 80%.
If Centrelink payments make up a significant portion of your household income, it's worth knowing which lenders have the most supportive policies before you apply. Not all lenders will consider this income, and applying to the wrong one can result in a declined application that then appears on your credit file.
What Happens If Your Income Doesn't Fit the Standard Model
Lenders operate on policy matrices that favour consistent, verifiable, long-term income. If your income comes from multiple sources, includes foreign currency, or involves trust distributions, commission, or seasonal work, your application will take longer and require more documentation. This doesn't mean you can't borrow, but it does mean you need to present your financial situation in a way that meets the lender's verification requirements.
As an example, a buyer in Ringwood working part-time in aged care while building a consulting business might have $55,000 in PAYG income and $30,000 in ABN income. One lender might assess only the PAYG component because the business is less than two years old. Another might accept both income streams if the business has consistent invoicing and a strong pipeline. Knowing which lender to approach with which documentation is the difference between borrowing $400,000 and $550,000.
Documents You'll Need to Provide
The exact documents required depend on your income type, but you should be prepared to provide recent payslips, a letter of employment or contract, tax returns and Notices of Assessment if self-employed, bank statements showing salary deposits, and evidence of any additional income like rental payments or dividends. Lenders may also request a separation certificate if you've recently left a job, or a statutory declaration explaining any gaps in employment.
Having these documents ready before you apply speeds up the process and reduces the chance of your home loan application being delayed or declined due to incomplete information.

Frequently Asked Questions
Can I get a home loan if I'm self-employed?
Yes, self-employed buyers can qualify for a home loan by providing two years of tax returns and Notices of Assessment. Lenders assess your taxable income, so deductions that reduce your tax also reduce your borrowing capacity, though some lenders allow add-backs for non-cash expenses like depreciation.
Do lenders accept casual or contract income for home loans?
Lenders will accept casual and contract income if you can show at least six months of consistent work, though 12 months is preferred. You'll need payslips, a letter confirming ongoing employment, and often a contract or roster showing future shifts.
How does changing jobs affect my home loan application?
Changing jobs in the same industry with similar or higher income is generally accepted once probation ends. Some lenders will approve during probation with an unconditional offer letter and strong employment history in the same field.
Will rental income from an investment property help me borrow more?
Lenders include rental income in their assessment but typically use only 80% of the gross rent to account for vacancies and maintenance. This income is added to your other earnings when calculating borrowing capacity.
What documents do I need to prove my income for a home loan?
You'll generally need recent payslips, a letter of employment or contract, and bank statements showing salary deposits. Self-employed applicants must provide two years of tax returns and Notices of Assessment, while casual workers need payslips covering at least six months.
