What Banks Look at When Assessing a Home Loan Application (Australia 2026)
When you apply for a home loan, lenders conduct a comprehensive assessment of your ability and willingness to repay. Understanding what they look at can help you present the strongest application.
The 5 Cs of Home Loan Assessment
Australian lenders — guided by responsible lending obligations under the National Consumer Credit Protection Act (NCCP) — typically assess applications across five dimensions:
| C | What it means |
|---|---|
| Capacity | Can you afford the repayments? (income, expenses, serviceability) |
| Capital | How much deposit do you have? (LVR, equity) |
| Credit | How have you managed debt in the past? (credit file, score) |
| Character | Stability and reliability (employment history, residential history) |
| Collateral | Is the security property suitable? (type, location, value) |
1. Income — Capacity to Repay
Lenders verify your income to assess how much you can service. Different income types are treated differently:
| Income type | Typical lender treatment |
|---|---|
| PAYG salary (full-time) | 100% of gross income |
| PAYG salary (part-time) | 100% if established (12+ months) |
| PAYG casual | 100% if 12+ months continuous |
| Self-employed | 2 years’ average net business income (with tax returns) |
| Rental income | 70–80% of rental income (to allow for vacancies, expenses) |
| Investment dividends | Varies — 2 years’ average, discounted |
| Government benefits | Varies — Centrelink income typically only partially accepted |
Income documents required: Pay slips (last 2), bank statements (last 3–6 months), most recent group certificate or tax return, ATO Notice of Assessment.
2. Expenses — Actual vs Declared
Since the banking Royal Commission and APRA guidance, lenders have significantly tightened expense verification. They now look beyond what you declare to also check your bank statements.
Lenders assess two sets of expenses:
- Declared living expenses — what you tell them you spend (HEM benchmark as a minimum)
- Actual bank statement expenses — 3–6 months of real spending data
Household Expenditure Measure (HEM): A benchmark of minimum household spending based on ABS data. Lenders use the higher of your declared expenses or the HEM benchmark. If your actual expenses shown in bank statements exceed the HEM, they use actual.
What shows up on bank statements that lenders notice:
- Regular gambling transactions
- BNPL (Afterpay, Zip) accounts
- Subscriptions and memberships
- High restaurant/entertainment spending
- Regular loan/lease repayments not declared
- Paywave and casual spending patterns
3. Serviceability Buffer
Under APRA guidelines, all Australian ADIs (banks, building societies, credit unions) must add a minimum 3 percentage point buffer above the actual loan rate when assessing serviceability.
Example:
- Actual interest rate: 6.00%
- Assessment rate: 6.00% + 3.00% = 9.00%
Your income must be sufficient to service the full loan at the assessment rate of 9.00%, not 6.00%. This is a significant constraint on borrowing capacity.
4. Deposit and LVR
| LVR | Deposit | Lender tier |
|---|---|---|
| ≤60% | 40%+ | Best rates, easiest approval |
| 60–80% | 20–40% | Standard approval, no LMI |
| 80–90% | 10–20% | LMI required (added to loan) |
| 90–95% | 5–10% | LMI required; stricter criteria |
| >95% | <5% | Very limited options; guarantor or government schemes |
Lenders also look for genuine savings — typically at least 5% of the purchase price held in savings for 3+ months (not a gift or windfall). This demonstrates financial discipline.
5. Credit History
- Credit score (Equifax, Experian, or illion)
- Any defaults, court judgements, or bankruptcy
- Number and recency of credit enquiries
- Repayment history on existing credit (CCR data)

6. Employment Stability
| Employment situation | Lender assessment |
|---|---|
| Full-time PAYG, long-term employment | Strongest position |
| Full-time PAYG, <3 months at new job | May be accepted if in same industry; some lenders require probation to pass |
| Casual, 12+ months | Generally accepted with evidence of continuity |
| Self-employed, 2+ years | Standard — requires 2 years’ ATO assessments |
| Self-employed, <2 years | Very limited options; some non-bank lenders |
| Contractor | Depends on contract type and duration |
7. The Security Property
Lenders assess the property as security:
- Location: Some postcodes or regions are on restricted lists (e.g., mining towns, remote areas, very small towns) — lenders may not lend or apply lower LVRs
- Property type: Houses preferred; apartments (particularly high-density or studio) may attract lower LVR limits
- Valuation: Lender orders independent valuation — if lower than purchase price, LVR is calculated on the lower figure
- Construction: Off-the-plan apartments, owner-builder homes, and unusual construction types may have restrictions
Frequently Asked Questions
Can I borrow more if I have a co-borrower?
Yes — combined income is assessed. However, both borrowers’ credit histories are also assessed.
Does having HECS-HELP debt affect my borrowing capacity?
Yes — HECS-HELP repayments are included in your monthly expense obligations. The compulsory repayment threshold for FY2024–25 is $54,435. Lenders add the estimated HECS repayment to your obligations when calculating serviceability.
Do banks check social media or other data sources?
Not systematically — lenders rely on documented financial data (bank statements, payslips, credit files). However, bank statement analysis is comprehensive and may reveal spending patterns you hadn’t considered.
