Lenders approve home loans based on your capacity to repay, which means your income type and employment status directly determine both your loan amount and the interest rate you'll secure.
What Lenders Actually Assess Beyond Your Base Salary
Lenders calculate your borrowing capacity using your gross income, but the assessment extends far beyond your base wage. Overtime, bonuses, rental income, and self-employed earnings all receive different treatment when determining how much you can borrow.
Consider a buyer working in hospitality management near Ferntree Gully Village who earns a base salary of $75,000 with regular overtime averaging $15,000 annually. Most lenders will include 80% of that overtime figure if you can demonstrate at least six months of consistent payments through payslips. Some lenders require two years of history for overtime or commission income, which makes the choice of lender crucial before you lodge your home loan application.
Bonus income typically requires a longer track record. When assessing annual bonuses, lenders average the last two years and often apply only 80% of that average to your serviceability calculation. This conservative approach means a $20,000 annual bonus might contribute just $16,000 to your assessed income, reducing your potential loan amount by approximately $80,000 depending on current variable rates and your other commitments.
Self-Employed Borrowers Face Different Documentation Requirements
Self-employed applicants need two years of tax returns and financial statements to verify income, though some specialist lenders accept one year for established business owners.
In our experience working with self-employed buyers around the Ferntree Gully and Boronia areas, the figure lenders use isn't your take-home income but your taxable income plus any add-backs such as depreciation. As an example, a tradesperson operating as a sole trader might show $65,000 taxable income but after adding back $12,000 in depreciation and $8,000 in other allowable expenses, their assessed income becomes $85,000. This calculation substantially changes what you can borrow and which home loans become accessible.
Company directors present another layer of complexity. Lenders typically assess your director's salary plus dividends, averaged over two years. The timing of dividend payments can affect your application, particularly if you've recently started drawing more income through dividends rather than salary for tax efficiency.
How Casual and Contract Employment Affects Loan Approval
Casual employees can secure home loan approval, but lenders require at least six months of continuous employment with the same employer, though twelve months strengthens your position considerably.
The assessment focuses on consistency. A casual worker in retail at Mountain Gate Shopping Centre who demonstrates regular shifts and consistent hours over twelve months will receive full consideration of their income. Lenders review your payslips to calculate an average weekly income, then annualise that figure. Gaps in employment or irregular hours reduce the income figure lenders will use, directly affecting your borrowing capacity.
Contract workers with an Australian Business Number operating on multiple short-term contracts are generally treated as self-employed, requiring tax returns. Employees on fixed-term contracts through an employer receive different treatment. If you're between contracts at application time, most lenders won't proceed until you've commenced your next contract, even with a signed agreement in place.

Probation Periods and Recent Job Changes
Most lenders won't approve a home loan application while you're still within your probation period, though some will proceed if you've passed probation and can provide a letter from your employer confirming permanent status.
Changing jobs shortly before applying doesn't automatically disqualify you, particularly if you've moved within the same industry at the same or higher income level. A teacher moving between schools in the Knox area or an accountant changing firms typically proceeds without issue. Career changes into lower-paid roles or different industries receive closer scrutiny and may require you to wait until probation concludes.
The situation differs for first home buyers using guarantors. If your parents are guaranteeing part of your deposit and you're on probation, some lenders will proceed based on the reduced risk the guarantee provides, though this remains lender-specific.
Income Shading and How It Reduces Your Borrowing Power
Lenders don't assess your income at face value when calculating how much you can borrow. They apply a buffer to your potential repayments and assess whether you can service the loan at a rate typically 3% higher than the actual variable interest rate you'll pay.
This assessment rate means you're tested on your ability to repay at around 6-7% even if you're borrowing at current variable home loan rates closer to 4%. A loan amount of $600,000 might have actual monthly repayments around $3,200, but you'll be assessed on your ability to pay approximately $4,200 monthly. Your income must cover this higher figure plus your existing debts and living expenses.
Some lenders also shade certain income types by applying a percentage rather than using the full amount. Rental income from investment properties typically has 20% deducted to account for vacancy periods and maintenance costs, even if you've never had a vacancy. This reduces a $30,000 annual rental income to $24,000 for assessment purposes.
Positioning Your Application Around Employment Status
Knowing how lenders assess your specific employment type allows you to time your application strategically and choose lenders aligned with your income structure.
If you're self-employed and approaching your financial year end, waiting until you've lodged your tax return can strengthen your application if your most recent year shows higher income. Conversely, if you know your income will be lower this year, applying before you lodge that return keeps your assessment based on the stronger previous period.
For employees with variable income through overtime or commissions, building a longer track record before applying increases the income figure lenders will use. Six months of consistent overtime is minimum for many lenders, but twelve months of history can mean the difference between an 80% inclusion rate and 100% inclusion, potentially adding tens of thousands to your available loan amount.
Understanding your borrowing capacity before you start searching for property prevents disappointment. Our borrowing power calculator provides an initial indication, though a detailed assessment considers your specific circumstances and identifies which lenders will maximise your borrowing capacity based on your employment type.
Your employment status affects more than just loan approval. It influences the interest rate discount you can negotiate, whether you'll pay Lenders Mortgage Insurance, and which loan features become available. A detailed conversation about your income structure and how different lenders assess it positions you to secure a loan that matches both your current employment and your plans for the property.

Frequently Asked Questions
Can I get a home loan while on probation?
Most lenders require you to have passed probation before approving a home loan, though some will proceed if you can provide written confirmation from your employer that you've completed probation and are now permanent. If you're using a guarantor, some lenders may be more flexible during probation periods.
How do lenders assess overtime and bonus income?
Lenders typically include 80% of overtime income if you can demonstrate at least six months of consistent payments, though some require two years of history. Bonus income usually requires a two-year average, with lenders applying only 80% of that averaged figure to your borrowing capacity calculation.
What income documents do self-employed borrowers need?
Self-employed applicants generally need two years of tax returns and financial statements, though some specialist lenders accept one year for established business owners. Lenders assess your taxable income plus add-backs such as depreciation rather than your take-home income.
Can casual employees get approved for a home loan?
Yes, casual employees can secure home loan approval with at least six months of continuous employment with the same employer, though twelve months strengthens your position. Lenders assess the consistency of your hours and calculate an average weekly income to determine your borrowing capacity.
How does rental income from investment properties affect borrowing capacity?
Lenders typically shade rental income by deducting 20% to account for potential vacancy periods and maintenance costs, even if you've maintained full occupancy. This means $30,000 in annual rental income becomes $24,000 for assessment purposes when calculating how much you can borrow.
