1. How Lenders Assess Investment Property Loans

Financing an investment property in Australia differs significantly from purchasing an owner-occupied home. Lenders assess both your personal earned income and the property's projected rental income.

To account for vacancy periods, property management fees, and council rates, lenders apply a 20% to 30% shading factor to rental income, assessing only 70% to 80% of gross rental yields in serviceability calculations.

2. Principal & Interest (P&I) vs Interest-Only (IO) Structures

Choosing between P&I and Interest-Only is a critical tax and cash flow decision for property investors:

• Interest-Only Loans: Minimize monthly cash commitments, maximizing tax-deductible interest deductions against rental income while directing surplus cash flow toward non-deductible owner-occupied debt or high-growth offsets.
• Principal & Interest Loans: Offer lower interest rate pricing (typically 0.20% to 0.40% lower than IO rates) and steadily build property equity over time.

3. Using Existing Home Equity as an Investment Deposit

Seasoned Australian investors rarely use physical cash savings for investment deposits. By establishing a separate supplementary equity loan (split loan) against their owner-occupied property, they fund the 20% deposit plus stamp duty while keeping the main investment loan isolated, avoiding cross-collateralization.
