Your borrowing capacity determines how much a lender will let you borrow, and in Eastwood where property demand remains strong near the train station and Rowe Street precinct, that figure can make the difference between securing a property or missing out.
What Actually Affects Your Borrowing Capacity
Lenders calculate how much you can borrow by assessing your income against your existing commitments and living expenses, then applying a buffer rate to ensure you could still afford repayments if interest rates rose. Your gross income forms the starting point, whether that's salary, rental income from investment property, or business income if you're self-employed. From there, lenders subtract your monthly commitments like credit card limits, personal loan repayments, HECS debt, and even childcare costs or school fees. What remains is your serviceability, the amount available to cover a mortgage repayment at a rate typically 3% higher than the actual variable rate you'd pay.
Consider a buyer earning $95,000 annually with a $12,000 credit card limit, a $15,000 car loan, and monthly living expenses that the lender estimates at around $2,200. Even if the credit card has a zero balance, lenders assess it at the full limit, assuming you could draw on it at any time. That $12,000 limit reduces borrowing capacity by roughly $50,000 to $60,000 depending on the lender. The car loan repayment of $350 per month might trim another $70,000 from what you can borrow. After running those numbers through their serviceability calculator, this buyer might be approved for $520,000 when they expected closer to $600,000. Closing the credit card and paying out the car loan before applying lifts that capacity back up, opening access to properties they couldn't previously reach.
How Lenders Treat Different Income Types
Salaried income is the most straightforward for lenders to assess, typically requiring two recent payslips and a letter of employment. Self-employed borrowers in Eastwood, whether running a business along Rowe Street or working as contractors in the surrounding commercial areas, face a different assessment. Most lenders require two years of tax returns and financials, averaging your net profit after deductions and add-backs. If your taxable income dropped between years due to purchasing equipment or other legitimate deductions, lenders may use the lower figure or average both years, which can compress your borrowing capacity even if your actual cash flow is strong.
Rental income from an investment property is generally assessed at 80% of the gross rent to account for vacancy periods and maintenance costs. If you're receiving $600 per week in rent, the lender includes $480 per week as income, but also factors in the existing mortgage repayment on that property as a commitment. The net effect on borrowing capacity depends on whether the rental income exceeds the assessed loan repayment.

The Impact of Existing Debt on What You Can Borrow
Every ongoing commitment reduces the amount a lender will approve. HECS debt doesn't require monthly repayments in the traditional sense, but lenders still factor it in by reducing your assessable income by the compulsory repayment percentage that applies at your income level. At an income of $80,000, that might be around 4% of your gross salary, which effectively lowers the income figure the lender uses to calculate serviceability.
Buy now, pay later accounts have come under closer scrutiny. Some lenders now treat these as ongoing commitments, particularly if your credit file shows multiple active accounts or recent missed payments. A $2,000 limit across two platforms might only shave $5,000 to $10,000 off your borrowing capacity, but if you're right on the edge of affording a property, that margin matters.
In our experience, buyers often underestimate how much their credit card limits affect their application. A couple with three credit cards totalling $35,000 in available credit might see their borrowing capacity drop by $150,000 or more compared to having no cards at all. If you're not using those cards regularly, closing them before you apply for a home loan delivers an immediate lift in what lenders will approve.
How Deposit Size Connects to Borrowing Power
A larger deposit doesn't increase your borrowing capacity directly, but it reduces the loan amount you need, which means you can access properties at higher price points without borrowing beyond your serviceability limit. Lenders also view a bigger deposit as lower risk. If you're borrowing above 80% of the property value, you'll pay Lenders Mortgage Insurance, which gets added to your loan amount and further reduces how much you can borrow for the actual property.
A buyer with $70,000 saved and borrowing capacity of $550,000 can target properties up to $620,000. If that same buyer increased their deposit to $100,000, they could now look at properties up to $650,000 without needing to borrow more or stretch their serviceability. For buyers relying on the First Home Guarantee Scheme, a 5% deposit avoids LMI, meaning more of your borrowing capacity goes toward the property rather than insurance premiums.
Using Loan Structure to Preserve Flexibility
Choosing between variable rate, fixed rate, or a split loan doesn't change your borrowing capacity, but the features attached to your loan structure can affect your financial position over time. An offset account linked to your owner occupied home loan lets you park savings against the loan balance, reducing interest without locking those funds away. That preserves access to cash if your circumstances change or if you want to build equity faster by making extra repayments when you can afford it.
Some buyers opt for interest only repayments to keep monthly costs lower in the short term, particularly if they expect income to rise or plan to sell within a few years. Lenders assess interest only loans more conservatively, so your borrowing capacity may be slightly lower compared to a principal and interest loan, but the reduced repayment can help with cash flow if you're managing other commitments.
Why Pre-Approval Matters Before You Start Looking
Getting home loan pre-approval before you attend inspections or make offers tells you exactly what you can borrow, not what you think you can borrow. Pre-approval involves a full assessment of your income, expenses, and credit history, giving you a clear borrowing limit that's valid for three to six months depending on the lender. In Eastwood, where properties near the station or within the Eastwood Public School catchment can attract multiple offers, knowing your limit means you can move quickly without the risk of discovering mid-process that you've overcommitted.
Pre-approval also highlights any issues with your borrowing capacity early enough to address them. If your credit report shows a default you'd forgotten about, or your living expenses are higher than the lender's benchmark, you'll know before you're emotionally invested in a property. That gives you time to clear the default, reduce your commitments, or adjust your budget.
When to Review Your Borrowing Position
Your borrowing capacity isn't static. Income changes, debt gets paid down, living expenses shift, and lender policies are regularly updated. If you've been pre-approved but haven't found a property within a few months, it's worth revisiting your position, particularly if interest rates have moved or your financial situation has changed. A loan health check can also identify whether your current loan structure still suits your circumstances, or if refinancing could improve your serviceability for future borrowing.

Frequently Asked Questions
What is borrowing capacity and how do lenders calculate it?
Borrowing capacity is the maximum amount a lender will let you borrow based on your income, existing debts, and living expenses. Lenders assess your gross income, subtract your commitments and expenses, then calculate how much you can afford to repay using a buffer rate that's typically 3% higher than current variable rates.
How much does a credit card limit reduce my borrowing capacity?
Even with a zero balance, a credit card limit is assessed as if fully drawn. A $10,000 credit card limit can reduce your borrowing capacity by approximately $40,000 to $50,000 depending on the lender. Closing unused cards before applying for a home loan can significantly increase what you're approved to borrow.
Does a larger deposit increase how much I can borrow?
A larger deposit doesn't increase your borrowing capacity directly, but it reduces the loan amount you need, allowing you to target higher-priced properties. It also helps you avoid Lenders Mortgage Insurance if you're borrowing 80% or less of the property value, meaning more of your borrowing power goes toward the property itself.
Why does home loan pre-approval matter before looking at properties?
Pre-approval gives you a confirmed borrowing limit after a full assessment of your finances, so you know exactly what you can afford before making an offer. It also identifies any issues with your credit or serviceability early, giving you time to address them before you're committed to a property.
How do lenders assess self-employed income for borrowing capacity?
Self-employed borrowers typically need two years of tax returns and financial statements. Lenders average your net profit after deductions, and if your income varied between years, they may use the lower figure or an average, which can reduce your borrowing capacity compared to salaried applicants.
