Avoid These Income Mistakes on Your Home Loan

Lenders don't assess your income the way you do.

What you earn on paper and what a lender will actually use to calculate your borrowing capacity are often two different numbers. The difference can cost you hundreds of thousands in purchasing power, or it can mean the difference between approval and decline. Understanding how lenders view your employment type and income structure matters before you fill out a home loan application.

Not All Income Counts the Same Way

Lenders apply different treatment depending on your employment type. Permanent full-time employees with a base salary typically see 100% of that income accepted without question. The moment your income includes bonuses, commissions, overtime, or shift allowances, lenders start applying discounts or requiring evidence of consistency.

Consider a professional in Bellevue Hill earning a base salary of $150,000 plus an annual bonus that's averaged $40,000 over the past two years. Some lenders will use 100% of that bonus if it's contractual and evidenced through tax returns and payslips. Others will discount it to 80% or require a three-year history before they include it at all. That $40,000 bonus might contribute $40,000 to your borrowing capacity with one lender and $32,000 with another, or nothing if you've only received it for one year. The property you can afford shifts accordingly.

Self-Employed Income Takes Longer to Prove

If you're self-employed, lenders want to see two years of tax returns showing consistent or increasing income. They'll typically use the average of those two years, and some will apply further reductions if your income trend is declining. A business owner who netted $200,000 last financial year but $160,000 the year before might find their income assessed at $180,000, or in some cases closer to the lower figure depending on the lender's policy.

Many self-employed applicants in Bellevue Hill run expenses through their business to reduce taxable income. That strategy works well for tax purposes but reduces what a lender will count. If you're planning to apply for a home loan within the next 12 to 24 months, the income you declare on your tax return becomes more important than the deductions you claim. Speak with your accountant about the trade-off before lodging your next return.

Casual and Contract Workers Need a Longer Paper Trail

Casual employees and contractors face similar scrutiny to the self-employed. Lenders want evidence that your income is stable and likely to continue. That usually means at least 12 months with the same employer or in the same field, supported by payslips, tax returns, and sometimes a letter from your employer confirming ongoing work.

If you've been contracting through your own company, lenders will treat you as self-employed and require two years of financials. If you're a PAYG contractor, some lenders will assess you as an employee after 12 months of consistent work, while others will still want two years. The structure of your employment matters as much as the amount you earn.

Investment Income and Rental Properties Add Complexity

Rental income is rarely counted dollar for dollar. Most lenders will use 80% of the rental amount shown on your lease agreement to account for vacancies, maintenance, and management costs. If you're purchasing an investment property and relying on future rental income to service the loan, many lenders won't include that income at all until the lease is signed and the tenant is in place.

Dividend income, trust distributions, and other investment returns are treated conservatively. Lenders want to see that the income is recurring and supported by tax returns or financial statements. One-off distributions or irregular payments are usually excluded.

Overtime and Allowances Aren't Automatic

Shift allowances, overtime, and car allowances often make up a significant portion of income for nurses, tradespeople, and emergency services workers around the eastern suburbs. Lenders will consider this income, but they'll want at least six to 12 months of payslips showing it's regular. They'll often average it over that period rather than using the most recent figure, so a strong couple of months won't compensate for a quieter period earlier in the year.

If your payslip separates base pay from allowances, be prepared to explain what each component represents and provide evidence it will continue. A car allowance that's conditional on your current role might not be counted if there's any doubt about its permanence.

Timing Your Application Around Employment Changes

Changing jobs or starting a new business just before applying for a home loan creates problems. Lenders view job changes as a risk, even if your new role pays more. If you're still in a probation period, many lenders won't assess your application until you've passed probation and can provide a letter confirming permanent employment.

Starting a new business means waiting at least two years before most lenders will consider your income. If you're planning a career shift or thinking about going out on your own, finalise your home loan pre-approval before you make the move, not after.

Documents You'll Need Before You Apply

Your income type determines what evidence the lender requires. Employees need recent payslips, usually the two most recent, plus either a letter of employment or access to your employer's verification system. Self-employed applicants need two years of tax returns, two years of financial statements, and often a letter from your accountant. If your business is structured through a company or trust, you'll need the business tax returns as well as your own.

If you're relying on rental income, bring signed lease agreements and evidence the rent is being paid, such as bank statements showing the deposits. If you're receiving child support or government benefits and need to include that income, bring the Centrelink statement or legal agreement confirming the amount and duration.

Missing documents delay the process. Gather everything before you start your application, especially if you're working to a settlement deadline.

How Lenders Calculate What You Can Borrow

Once your income is confirmed, lenders subtract your existing debts, living expenses, and a buffer to determine how much you can borrow. The buffer accounts for potential interest rate increases, typically adding 2% to 3% to the current variable rate. That means even if you're applying for a loan at a certain rate, the lender is testing whether you could still afford repayments if rates rose.

Living expenses are assessed using either your actual spending, shown through bank statements, or a benchmark figure based on your household size. In higher-cost areas like Bellevue Hill, lenders are more likely to accept declared expenses that exceed their benchmark, but they'll still want to see that your spending is sustainable relative to your income.

If your expenses are high relative to your income, or if you have existing debts like personal loans or car loans, your borrowing capacity drops. Paying down small debts before applying can improve your position more than increasing your deposit in some cases.

Why Some Applications Get Declined Despite Strong Income

A high income doesn't guarantee approval. Lenders also assess the stability and verifiability of that income. If your income fluctuates significantly from month to month, if you've recently changed jobs, or if you can't provide the required documentation, the application can be declined even if the dollar figure is well above what the loan requires.

Credit history, employment gaps, and the way you manage your existing accounts all factor into the decision. An applicant earning $300,000 a year can be declined if their bank statements show regular missed payments, frequent overdrafts, or unexplained cash deposits that suggest undeclared income or other complications.

Tidy up your accounts at least three months before applying. That means no missed payments, no new credit applications, and no large cash deposits or transfers that you can't explain.

Preparing your income documentation properly and understanding how lenders will assess it improves your chances of approval and often results in a higher borrowing capacity than you'd get by guessing what's required. Call one of our team or book an appointment at a time that works for you.
