Your borrowing capacity determines how much a lender will approve for your home loan, and that figure can vary significantly between lenders even when your financial position remains the same.
Lenders assess your income, expenses, existing debts, and financial commitments through their own serviceability calculators. Each institution applies different buffers and assessment rates to your application, which means the loan amount you qualify for with one bank may differ by tens or even hundreds of thousands of dollars compared to another.
How Lenders Calculate What You Can Borrow
Lenders use a serviceability assessment that takes your gross income and subtracts your declared living expenses, existing debt repayments, and any other financial commitments. They then test whether you can afford the loan repayments at an assessment rate that sits above the actual interest rate you would pay. This buffer accounts for potential rate rises during the loan term.
Consider a buyer in the Barossa Region earning $95,000 annually with a car loan repayment of $450 per month and typical living expenses for a single person. One lender might assess their borrowing capacity at $485,000, while another using a lower expense benchmark or different buffer rate could approve $520,000. The variation comes down to each lender's risk appetite and internal policy settings.
Income Sources That Strengthen Your Application
Permanent employment income receives full weighting in most serviceability calculations. Lenders typically require payslips covering the most recent pay cycle and may ask for employment contracts or a letter from your employer confirming your position and salary.
Casual and contract income usually requires a longer track record. Most lenders want to see at least six to twelve months of consistent earnings in the same role or industry before they will include that income at full value. Self-employed applicants generally need two years of tax returns and financial statements prepared by an accountant, though some lenders will consider one year of returns if your business shows strong, stable income.
Rental income from an investment property is typically assessed at 80% of the actual rent received to account for vacancy periods and maintenance costs. Overtime, bonuses, and commission income may be included if you can demonstrate a consistent pattern over at least six months, though policies vary between lenders.
Debt and Expenses That Reduce Borrowing Power
Credit card limits affect your application even when the balance is paid in full each month. Lenders assume you could draw the full limit at any time, so they factor in a minimum monthly repayment based on that limit when calculating your capacity. A card with a $15,000 limit might reduce your borrowing power by $40,000 or more, depending on the lender's calculation method.
Personal loans, car loans, and Buy Now Pay Later accounts all reduce the amount you can borrow. If you are close to your borrowing limit and have debts that will be cleared within six months, paying them out before applying can increase the loan amount available to you. Some lenders will exclude a debt from their assessment if you provide evidence that it has been closed and the final statement shows a zero balance.
Declared living expenses also play a role. Lenders use either your actual declared expenses or a benchmark figure based on the Household Expenditure Measure, whichever is higher. For a single applicant in regional South Australia, that benchmark typically sits between $1,800 and $2,200 per month depending on the lender. Families with dependents face higher benchmarks that increase with each child.
Loan Features That Affect How Much You Can Borrow
Interest-only repayments reduce your monthly commitment during the interest-only period but also reduce your maximum loan amount. Lenders assess interest-only applications more conservatively because you are not reducing the principal, which means the loan carries higher risk over time.
Some lenders apply a higher assessment rate or lower maximum loan-to-value ratio for interest-only requests. If your goal is to maximise borrowing capacity, switching to principal and interest repayments during the application process can increase the amount you qualify for, even if you plan to request interest-only terms after settlement.
An offset account does not typically affect your borrowing capacity, but choosing a loan package with higher fees or a packaged product with additional features may reduce the loan amount if those ongoing costs push you closer to your serviceability limit.
When to Seek Pre-Approval Before Property Hunting
A pre-approval provides a conditional commitment from a lender based on your financial position and the loan amount you have requested. This approval is subject to a satisfactory property valuation and confirmation that your circumstances have not changed.
For buyers in the Barossa Region where property stock can move quickly, having pre-approval in place means you can make an offer with confidence. It also gives you a clear understanding of your price range before you start attending inspections, which prevents the disappointment of finding a property you cannot afford or the inefficiency of looking at homes well below what you can borrow.
Pre-approval typically lasts between three and six months depending on the lender. If your settlement extends beyond that period, most lenders will extend the approval provided your income and debts remain unchanged.
Strategies to Increase Your Loan Amount
Reducing your credit card limits or closing unused accounts before applying can immediately increase your capacity. If you hold multiple cards, consolidating to a single card with a lower limit has the same effect.
Increasing your deposit also increases your borrowing power indirectly by reducing the loan amount required and potentially avoiding Lenders Mortgage Insurance. LMI premiums are capitalised into the loan in many cases, which increases the total amount you need to borrow and can push some applicants beyond their serviceability threshold.
If you are applying with a partner or co-borrower, including their income strengthens the application. Lenders assess joint applications based on combined income and combined debts, so provided the other applicant has stable income and minimal liabilities, their inclusion will increase the total loan amount available.
Switching lenders or working with a broker who has access to multiple lenders allows you to compare serviceability across different institutions. A lender that assesses casual income more favourably or applies a lower living expense benchmark may approve a significantly higher loan amount than the lender you approach directly. Our broking panel includes access to home loan options from banks and lenders across Australia, which allows us to match your circumstances to the lender most likely to provide the outcome you need.
The loan amount you qualify for depends on lender policy as much as your financial position. Call one of our team or book an appointment at a time that works for you to discuss your borrowing capacity and the options available to you in the Barossa Region.
Frequently Asked Questions
How do lenders calculate my borrowing capacity?
Lenders assess your gross income and subtract your living expenses, existing debt repayments, and other financial commitments. They then test your ability to service the loan at an assessment rate higher than the actual interest rate to account for potential rate rises.
Why does my credit card limit affect how much I can borrow?
Lenders assume you could draw the full credit limit at any time, so they factor in a minimum monthly repayment based on that limit when calculating your capacity. A high limit can reduce your borrowing power by tens of thousands of dollars even if the balance is always paid in full.
Does choosing interest-only repayments reduce my borrowing capacity?
Yes, lenders assess interest-only applications more conservatively because you are not reducing the principal during the interest-only period. Some lenders apply a higher assessment rate or lower maximum loan-to-value ratio for these requests.
How long does home loan pre-approval last?
Pre-approval typically lasts between three and six months depending on the lender. Most lenders will extend the approval beyond that period provided your income and debts remain unchanged.
Can I increase my borrowing capacity before applying?
Yes, reducing credit card limits, closing unused accounts, paying out short-term debts, and increasing your deposit can all increase the loan amount you qualify for. Switching to a lender with more favourable serviceability settings can also make a significant difference.
