Single-Income Budgeting for Home Loans

Managing finances on a single income while pursuing homeownership requires strategic planning and understanding of lender requirements. This comprehensive guide will help you optimize your financial position for loan approval.

What Australian Lenders Assess

The Four Pillars of Single-Income Assessment

1. Income Adequacy and Stability

• Employment Type: Permanent positions strongly preferred
• Length of Employment: Minimum 3-6 months, ideally 2+ years
• Income Growth: Evidence of career progression
• Supplementary Income: Child support, government benefits, investment returns

2. Debt-to-Income Ratio (DTI) Most major Australian banks now use DTI caps:

• Commonwealth Bank: 6 times gross income
• Westpac: 7 times gross income
• ANZ: 6-7 times gross income
• NAB: 6-7 times gross income
• Regional lenders: Often more flexible up to 8 times

3. Serviceability Assessment

• Net Income After Tax: Your take-home pay calculation
• Living Expenses: Household Expenditure Measure (HEM) plus actual expenses
• Interest Rate Buffer: Lenders test at 2-3% above actual rate
• Other Debt Commitments: Credit cards, personal loans, car loans

4. Creditworthiness

• Credit Score: Minimum 600, preferably 700+
• Payment History: 24 months of clean payment behavior
• Credit Utilization: Keep credit cards under 30% of limits

Debt-to-Income Ratio Benchmarks

Major Bank DTI Caps (2025)

Tier 1 Banks:

• CBA: 6x gross income (strictly enforced)

• If you want a $550,000 loan: Exceeds CBA but may qualify with Suncorp

Example 2: $60,000 Income + $20,000 Child Support

• Total assessed income: $80,000 (assuming 100% of child support counted)
• Most lenders cap: $480,000-$640,000 depending on institution
• Child support documentation crucial for maximizing capacity

Credit Score Requirements and Improvement

Minimum Credit Score Thresholds

Prime Lenders (Major Banks):

• 700+: Best rates and terms available
• 650-699: Standard products with competitive rates
• 600-649: Limited products, higher rates
• Below 600: Specialist lenders required

Specialist Lenders:

• 550-599: Options available but at premium rates
• 500-549: Very limited options, significant restrictions

Borrowing Capacity Calculations

Basic Calculation Method

Step 1: Calculate Net Income

• Gross salary: $70,000
• Less tax and Medicare levy: ~$14,500
• Add family tax benefits: ~$3,000
• Add child support: $15,000
• Net monthly income: ~$6,125

Step 2: Calculate Living Expenses

• Lender's Household Expenditure Measure: ~$2,800
• Actual declared expenses (if higher): Use actual
• Add dependent children costs: ~$500 per child
• Total monthly expenses: ~$3,800

Step 3: Apply Interest Rate Buffer

• Current rate: 6.5%
• Buffer rate: 8.5-9.5%
• Assessment rate: 8.5%

Step 4: Calculate Borrowing Capacity

• Available for loan repayments: $6,125 - $3,800 = $2,325
• Maximum monthly repayment at 8.5%: ~$2,200 (including buffer)
• Estimated borrowing capacity: ~$290,000

Factors That Increase Borrowing Capacity

Income Enhancements:

• Rental income: 70-80% typically counted
