The Four Cs of Credit

The Four Cs of Credit

The Four Cs — Character, Capacity, Capital, and Collateral — are the underlying analytical model of credit assessment. Every assessment procedure a lender runs maps to one of these four dimensions.

Character

Character is the borrower's track record of meeting financial obligations. In Australian lending, this is assessed through:

• The credit file: Accessed via Equifax, Illion, or Experian. The file shows active credit facilities, limits, repayment history, defaults, and credit enquiries.
• Comprehensive Credit Reporting (CCR): Since 2018, positive and negative repayment history is included in credit reports. A borrower who consistently pays on time builds positive CCR history; late payments are visible to subsequent lenders.
• Bank statement conduct: The most recent 3–6 months of bank statements are reviewed. Assessors look at how accounts are managed — recurring overdrafts, dishonoured payments, patterns of gambling transactions, and sustained BNPL usage are all relevant.

Character assessment is about reliability and financial management, not just the absence of defaults.

Capacity

Capacity is the ability to service the proposed debt from verified income. The core test: does the borrower's net assessed income exceed their verified expenses plus the new loan repayment — calculated at approximately 3% above the actual product rate (the APRA serviceability buffer)?

Every income source is classified and adjusted according to lender policy before it enters the calculation. Every existing liability — mortgage repayments, credit card limits, personal loans, leases, HECS — is stressed and deducted. The resulting Net Surplus Income (NSI) or Net Quality Ratio (NQR) must be positive. A negative NSI means the loan fails serviceability regardless of other factors.

Capacity is the most mechanically complex of the four Cs and the area where lender policy differences produce the most variation in outcomes.

Capital

Capital is the borrower's equity contribution. The key questions:

• What is the deposit, and where did it come from?
• Has it been genuinely saved over time, or assembled from other sources?
• Is there existing property equity that contributes to the LVR position?

The deposit size determines LVR. An LVR below 80% avoids LMI. At or above 80%, LMI is typically required. The accumulation method matters: lenders distinguish between genuine savings (gradually accumulated by the borrower) and other funds to complete (gifts, inheritances, tax refunds), which may require supplementary evidence or a holding period.

For property investors, capital also encompasses equity in existing properties — which can be accessed to fund future purchases, subject to serviceability.

Collateral

Collateral is the property offered as security. The lender's assessment of collateral is independent of the borrower's financial position — a strong borrower with weak collateral can still receive a constrained outcome.

The lender orders an independent valuation. This is the number used for LVR calculations, not the purchase price. If the valuation comes in below the contract price, the LVR calculation is based on the lower figure — and the borrower must fund the gap.

Property type, size, postcode, zoning, and market liquidity all affect what the lender is willing to lend against a specific property. Small apartments, regional locations, resort-style complexes, and non-standard property types attract LVR restrictions or may be outside policy entirely at some lenders.
