Your borrowing capacity is the maximum amount a lender will approve based on your income, expenses, debts, and financial commitments.
Lenders assess this differently, and what one lender approves might be $50,000 to $100,000 less than another. If you're looking at properties in Hawthorne, where the median house price sits above Brisbane's broader average and many character homes come with renovation potential or higher price tags, understanding how to present your financial position can make a real difference to what you can borrow.
Why Two Applicants with the Same Income Borrow Different Amounts
Borrowing capacity is not just about your salary. Two buyers earning identical incomes can receive vastly different loan approvals depending on how lenders assess their living expenses, existing debts, and financial behaviour.
Consider a buyer who earns $95,000 annually with a car loan balance of $18,000 and monthly credit card repayments of $400. That buyer might be approved for $480,000 with one lender. Another buyer on the same income with no car loan and a credit card limit of $5,000 they rarely use could be approved for $540,000 or more. The difference comes down to how much of your income is already committed to other debts and how lenders calculate your living expenses.
Lenders also apply different serviceability buffers, which is the margin they add to the interest rate when calculating whether you can afford repayments. One lender might assess your application at 3% above the actual rate, while another uses 2.5%. That small difference changes how much you can borrow, sometimes significantly.
Reducing Your Debt Commitments Before You Apply
Paying down or clearing existing debts before you apply for a home loan increases the amount lenders will approve.
If you have a car loan with $12,000 remaining and monthly repayments of $550, that repayment reduces your borrowing capacity by roughly $110,000 depending on the lender. Paying out that loan before applying can lift your approval amount by a similar figure. The same applies to personal loans, buy now pay later accounts, and credit card limits.
Credit cards are assessed on their limit, not the balance. A card with a $15,000 limit that you never use still affects your borrowing capacity as if you owed the full amount. Closing cards you don't need or reducing limits to $2,000 or less can add tens of thousands to your approval.
If you're buying in Hawthorne and competing for a Queenslander or a renovated home near the river precinct, having that extra $50,000 or $80,000 in borrowing capacity might be the difference between making an offer or missing out.

How Lenders Assess Your Living Expenses
Lenders use either your declared expenses or a benchmark figure called the Household Expenditure Measure (HEM), whichever is higher. HEM is a standardised estimate of how much a household spends based on size and location.
If your actual spending is lower than HEM, the lender still uses HEM. If your spending is higher, they use your actual figure. This means cutting back on discretionary spending in the months before you apply can help, but only if your expenses are already above the benchmark.
A buyer who regularly spends $1,200 a month on dining out, subscriptions, and weekend purchases might show $4,500 in monthly living expenses when HEM for their household sits at $3,800. Reducing discretionary spending to align closer to HEM improves serviceability. That said, lenders review your bank statements and will notice if you've temporarily shifted spending just before applying. Sustained changes over three to six months carry more weight.
For dual-income households in Hawthorne, where both applicants work full-time and have stable employment, living expenses are often one of the few levers you can adjust quickly without changing your debt position.
The Role of Income Structure and Employment Type
Your employment type affects how lenders calculate your income, which directly impacts borrowing capacity.
Full-time employees with a salary and no variable income are the most straightforward. Lenders use your base salary plus any allowances that are guaranteed and ongoing. Casual employees typically need 12 months of consistent hours before lenders will include that income, and even then, some lenders discount casual earnings by 20%.
Self-employed applicants usually need two years of tax returns, and lenders average the income across those years. If your most recent year shows higher income than the previous year, some lenders allow you to use the latest year only or apply weighting to give more importance to recent earnings. This can lift your borrowing capacity if your business income has grown.
In a scenario like this, a self-employed buyer in Hawthorne with taxable income of $78,000 in the first year and $102,000 in the second year might be assessed on an average of $90,000. With the right lender, that same buyer could be assessed closer to $102,000, which might add another $60,000 to $80,000 in borrowing capacity.
Using Rental Income to Increase Serviceability
If you already own an investment property or plan to rent out your current home after buying in Hawthorne, rental income can be used to support your application.
Lenders typically shade rental income, meaning they only count 80% of the rent to allow for vacancy periods and maintenance costs. If your investment property generates $480 per week, the lender will assess $384 per week as usable income. That still adds to your serviceability, particularly if the property is generating positive cash flow or close to it.
Some lenders allow you to use 100% of the rental income if the property is in a high-demand area or if you can demonstrate consistent tenancy history. This is more common with portfolio lenders who specialise in investors holding multiple properties.
For buyers moving from another Brisbane suburb into Hawthorne and keeping their previous home as a rental, structuring the application to maximise rental income recognition can be the difference between approval and rejection, particularly if the new property comes with a higher loan amount.
Choosing the Right Lender for Your Situation
Not all lenders assess borrowing capacity the same way, and matching your financial profile to the right lender is one of the most effective ways to increase what you can borrow.
Some lenders are more generous with casual income, others allow higher debt-to-income ratios, and a few assess living expenses using lower benchmarks or apply smaller serviceability buffers. A lender that works for a PAYG employee with no dependents might not be the right fit for a self-employed buyer with two children and a rental property.
Running your application through a mortgage broker who has access to serviceability calculators across multiple lenders lets you identify which lender will give you the highest approval before you formally apply. That avoids the situation where you apply with one lender, receive a lower-than-expected approval, and then need to either reapply elsewhere or adjust your property search.
For Hawthorne buyers, where properties around Oxford Street and the riverside pockets often attract multiple offers, knowing your maximum borrowing capacity upfront through the right lender means you can move quickly when the right property comes up.
Timing Your Application Around Financial Changes
When you apply matters, particularly if you've recently changed jobs, cleared a debt, or received a pay rise.
Lenders typically want to see three months of payslips in your current role, and some require six months if you've moved industries or changed from casual to permanent employment. If you've just started a new job with higher income, waiting another month or two before applying might increase your approval by $30,000 to $50,000.
Similarly, if you've just paid out a car loan or closed a credit card, wait until that change appears on your credit file before applying. Lenders pull your credit report as part of the assessment, and if the closed account is still showing as open, it will be included in their serviceability calculations. That usually takes one to two reporting cycles, or roughly 30 to 60 days.
If you're planning to buy in Hawthorne within the next few months and you're on the edge of your borrowing capacity, using that time to clean up your financial position rather than rushing into an application can result in a stronger approval and access to a wider range of properties.

Frequently Asked Questions
What is borrowing capacity and how is it calculated?
Borrowing capacity is the maximum loan amount a lender will approve based on your income, expenses, debts, and financial commitments. Lenders assess this using your salary, living expenses, existing debt repayments, and a serviceability buffer applied to interest rates.
How much can paying off a car loan increase my borrowing capacity?
Paying off a car loan can increase your borrowing capacity by roughly $110,000 for every $550 in monthly repayments you eliminate, depending on the lender. Clearing debts before applying removes those commitments from serviceability calculations.
Do credit card limits affect borrowing capacity even if I have no balance?
Yes, lenders assess credit cards based on their limit, not the balance. A card with a $15,000 limit affects your borrowing capacity as if you owed the full amount, so closing unused cards or reducing limits can increase your approval.
How do lenders assess income for self-employed buyers?
Self-employed buyers usually need two years of tax returns, and lenders average the income across those years. Some lenders allow you to use only the most recent year or apply weighting to recent earnings if your income has grown.
Why do different lenders offer different borrowing amounts for the same applicant?
Lenders use different serviceability buffers, living expense benchmarks, and policies for assessing income and debts. One lender might apply a 3% buffer while another uses 2.5%, and those differences can change your approval by $50,000 to $100,000 or more.
