Strategy 1 and 2: Remove Unused Credit Cards and Reduce Limits
The fastest way to how to increase borrowing capacity Perth is to cancel credit cards you do not use and reduce limits on cards you do keep. Here is why this has such a disproportionate impact:
Lenders assess credit card limits — not balances — as potential monthly liabilities. A $10,000 credit card limit is treated by most lenders as though you could draw the full $10,000 tomorrow. At a standard assessment of 3.8% per month of the limit, a $10,000 limit reduces your assessed monthly income by approximately $380. Over a 30-year loan at a serviceability rate of 8.9%, this translates to approximately $40,000 in reduced borrowing capacity.
Action: Before applying for a home loan, cancel every credit card you do not actively use. For cards you keep, reduce the limit to the minimum you genuinely need. A borrower with three cards at $10,000 limits who cancels them all can increase their maximum borrowing by approximately $120,000 with a single administrative action.
Strategy 3: Reduce Existing Debts Before Applying
Every existing debt – car loan, personal loan, BNPL account, student debt – reduces your assessed borrowing capacity directly. For a car loan with $15,000 remaining at $500/month in repayments, lenders reduce your assessed income by $500 every month. Over 30 years at serviceability rate, that $500/month reduction translates to approximately $55,000 less in home loan capacity.
If you have savings earmarked for a house deposit, consider whether using some of those savings to eliminate a car loan or personal loan first would increase your borrowing capacity by more than the deposit reduction costs you. In many cases, eliminating a debt increases your maximum loan by significantly more than the repayment amount suggests.
Strategy 4: Income Add-Backs for Self-Employed Perth Borrowers
One of the most powerful ways to how to increase borrowing capacity Perth for self-employed buyers is the income add-back analysis – and it requires a broker with accounting expertise to execute correctly. When a self-employed borrower’s taxable income is used for loan assessment, it reflects all legitimate tax deductions. But many of those deductions – depreciation, one-off expenses, non-cash charges – do not reduce the borrower’s actual cash available for mortgage repayments.
By identifying and adding back these non-cash deductions, a CA-qualified broker can increase the assessed income figure used by the lender. A self-employed Perth buyer with $120,000 in taxable income but $25,000 in legitimate add-backs may be assessed by a lender at $145,000 – increasing their borrowing capacity by approximately $100,000–$120,000 depending on the lender’s add-back policy. This is one of the single largest levers available to self-employed buyers and one that a standard broker without accounting knowledge cannot execute effectively.
Strategy 5: Manage Your HECS-HELP Debt Strategically
HECS-HELP debt is assessed by lenders based on your gross income, not your actual repayment amount. If your gross income is $120,000, your HECS repayment is approximately 6.5% or $7,800 per year – regardless of your actual loan balance. Lenders treat this as a mandatory commitment that reduces your capacity by the full repayment amount.
The strategic question is whether paying down your HECS debt before applying for a home loan is worthwhile. If your HECS balance is small – say under $20,000 – paying it off entirely removes the annual $7,800 repayment from lender assessment. Depending on lender policy, this can increase borrowing capacity by $30,000–$40,000.
Strategies 6 and 7: Choose the Right Lender and Timing
One of the most impactful ways to how to increase borrowing capacity Perth is simply choosing the lender whose policy is most favourable for your income type. The same borrower – identical income, identical expenses, identical deposit – can receive a maximum loan offer that varies by $50,000–$80,000 between different lenders. This variation comes from:
Timing also matters. Applying just after receiving a payslip that includes a bonus or overtime payment is better than applying the month before. Applying after a year of strong self-employment income with complete financials is better than applying mid-year with an incomplete picture.
Strategy 8: Increase Your Deposit or Access Equity
The final strategy to how to increase borrowing capacity Perth is the most straightforward: a larger deposit reduces your loan-to-value ratio, which can unlock lenders who cap borrowing at 80% LVR and reduce or eliminate LMI premium loading that some lenders apply to high-LVR loans.
For Perth buyers with family members who own property, a Guarantor Home Loan Perth strategy can effectively increase the deposit without requiring additional cash savings. A limited guarantor structure, where parents offer equity in their own property as additional security, can bring your LVR below 80%- unlocking the full lender panel and removing LMI from the equation entirely.
