Lenders approve or decline your home loan based on how they interpret your income and employment stability. Understanding what they look for lets you present your situation more clearly and address potential concerns before they become obstacles.
How Lenders Calculate Your Usable Income
Lenders don't use your gross salary as the basis for lending. They calculate your net income after tax, then deduct ongoing liabilities like personal loans, credit card limits, and living expenses. The amount left over determines what you can borrow.
Consider a buyer in Oakleigh earning $95,000 annually as a full-time graphic designer. After tax and a $12,000 personal loan, her take-home income might support a loan amount around $520,000, depending on other commitments. If she pays down that personal loan before applying, her borrowing capacity could increase by $60,000 or more. That difference can determine whether a property in the Oakleigh catchment is within reach.
Lenders apply a buffer to the interest rate when testing your repayment capacity, typically adding 3% to the current rate. This means even if variable rate products sit around 6%, your serviceability is tested at 9% or higher. The calculation is conservative by design, which is why clearing smaller debts and reducing credit limits has such a pronounced effect on what you can borrow.
The Employment Type That Lenders Prefer
Permanent full-time employment is the most straightforward income type to verify. Lenders typically require a recent payslip and an employment contract or letter confirming your role and salary. If you've been in the same role for more than six months, most lenders will assess your application without additional documentation.
Part-time and casual workers face more scrutiny. Lenders want to see consistent hours over at least 12 months, sometimes 24. If your hours fluctuate week to week, they may average your income over two years of tax returns rather than relying on recent payslips. This can work in your favour if your income has been stable or growing, but it delays your application if you've only recently increased your hours.
Contract workers and those in probationary periods are assessed case by case. Some lenders will accept your income once probation ends, while others require you to pass probation and provide evidence of ongoing employment. If you're moving between contracts in the same industry, demonstrating a consistent pattern of work helps offset the lack of permanent tenure.

Self-Employed and ABN Income: What Lenders Need to See
If you operate under an ABN, lenders will ask for two years of tax returns and often a notice of assessment from the ATO. They calculate your income by taking your taxable income and adding back certain deductions like depreciation. The goal is to establish a sustainable income figure rather than a one-off profitable year.
A buyer running a small online retail business from Oakleigh earned $78,000 in taxable income last financial year, but his accountant had written off $18,000 in vehicle and equipment depreciation. The lender added back $15,000 of those deductions, lifting his assessed income to $93,000. That adjustment increased his loan amount by roughly $75,000, giving him access to properties he initially thought were out of range.
If your business is structured as a company, lenders may require company financials, a profit and loss statement, and evidence of dividends or director's salary. The documentation is more involved, but the principle remains the same: they need to verify consistent, ongoing income. If your business is newer than two years old, some specialist lenders will assess you with one year of financials and evidence of forward contracts or recurring revenue, though interest rates may be slightly higher.
Bonus, Commission, and Overtime: When Lenders Count It
Lenders treat variable income components differently depending on consistency. Overtime and allowances are generally included if they appear on every payslip over at least three months, sometimes six. If your payslips show irregular overtime, lenders may exclude it entirely or average it over a longer period.
Commission and bonus income usually requires 12 to 24 months of history. Lenders calculate an average across that period and apply a discount, often 80%, to account for variability. If you earned $25,000 in commissions last year but only $15,000 the year before, they may use $16,000 as your assessable commission income. The longer your track record and the more stable the pattern, the more weight lenders place on that income.
If you've recently moved into a commission-based role, lenders may not count that income at all until you have at least one full financial year of earnings. In those situations, your base salary becomes the limiting factor. Paying down existing debts or adding a co-applicant with stable income can bridge the gap while you build your commission history.
How Multiple Income Sources Affect Your Application
Rental income from an investment property, government benefits, child support, and income from a second job can all contribute to your borrowing capacity, but lenders apply different rules to each. Rental income is typically shaded by 20% to account for vacancies and maintenance costs, so if you receive $500 per week in rent, lenders may only count $400.
Centrelink payments are generally acceptable if they're ongoing and verifiable, but short-term payments or those subject to review may be excluded. Child support requires a formal agreement and evidence of consistent payments over at least three months, sometimes six. Income from a second job is treated the same way as your primary employment: lenders want to see history and stability, not a one-off arrangement.
If you're combining several income streams, the application becomes more document-intensive. Gathering payslips, tax returns, rental statements, and Centrelink letters in advance speeds up the process. A broker can help structure your home loan application so that each income source is presented in the format lenders expect, reducing the chance of delays or requests for further information.
Why Your Employment History Matters as Much as Your Current Role
Lenders review not just your current job but your recent employment pattern. Frequent job changes, particularly across different industries, can raise concerns about income stability. If you've had three roles in the past 18 months, lenders may ask for an explanation or apply more conservative serviceability criteria.
Gaps in employment are scrutinised closely. If you took time off for parental leave, study, or travel, providing a clear explanation and evidence of your return to work helps. Lenders are more concerned with unexplained gaps or patterns that suggest inconsistent work history. If you've recently returned to the workforce after a break, having at least three months of payslips and a letter from your employer confirming ongoing employment strengthens your position.
Career progression within the same field is viewed positively, even if you've changed employers. Moving from a junior role to a senior position with higher income demonstrates stability and growing capacity. If you've recently been promoted or taken on additional responsibilities, updating your employment letter to reflect your new salary and role title ensures lenders assess you based on current circumstances.
Structuring Your Application to Match Your Income Type
How you present your income can make the difference between conditional approval and a decline. If you're on a visa with work rights, confirming the visa term and providing evidence of your intention to remain in Australia adds confidence to your application. If your income is paid in a foreign currency, lenders will convert it at a discounted exchange rate, so understanding that impact early helps you set realistic borrowing expectations.
For Oakleigh buyers working locally in sectors like healthcare, education, or trades around the Monash employment precinct, employment verification is usually direct. If you're working remotely for an interstate or overseas employer, lenders may request additional documentation such as contracts, bank statements showing salary deposits, and evidence of your employer's legitimacy. Preparing these documents before lodging your application avoids unnecessary delays.
If your income is complex or non-standard, working with a broker who understands lender policies across the panel gives you access to options you wouldn't find by approaching a single bank. Some lenders specialise in self-employed applicants, others in casual or contract workers. Matching your circumstances to the right lender improves your chances of approval at a rate that reflects your actual risk profile.
