Investment Property Finance 101

Getting started with investment property loans - deposits, structuring, interest-only options, and portfolio building.

Last updated: January 2025

Financing an investment property is different from buying your home. This guide covers what you need to know about investment loans, structuring, and building a portfolio.

Key Differences from Owner-Occupied Loans

  • Higher interest rates: Typically 0.2-0.5% higher than owner-occupied
  • Larger deposits: Most lenders require minimum 10%, prefer 20%
  • Rental income counted: Usually at 80% (to allow for vacancies)
  • Interest-only available: Up to 5 years for cash flow management

How Much Deposit Do You Need?

  • 10% deposit: Possible but you'll pay LMI and have limited lender options
  • 20% deposit: Recommended to avoid LMI and access better rates
  • Using equity: You may be able to use equity from your home instead of cash

Principal & Interest vs Interest-Only

Interest-Only (IO)

  • Lower repayments during the IO period
  • Maximizes cash flow
  • You're not paying down the loan
  • Typically available for up to 5 years

Principal & Interest (P&I)

  • Higher repayments but builds equity
  • Lower total interest over loan life
  • Better rates than IO

Strategic Tip

Many investors use IO on investment loans while paying P&I on their home loan. This maximizes tax-deductible debt while paying down non-deductible debt faster.

Loan Structuring

How you structure your loans matters for flexibility and tax efficiency:

Avoid Cross-Collateralization

Cross-collateralization is when multiple properties secure one loan. It can limit your flexibility and complicate selling or refinancing. We typically recommend separate loans for each property.

Use Offset on Owner-Occupied, Redraw on Investment

Offset accounts on your home loan reduce non-deductible interest. For investment properties, a redraw facility achieves similar benefits without the ATO complications.

Using Equity to Invest

If your home has increased in value, you can release equity to fund your investment deposit:

  1. Get your property valued
  2. Calculate usable equity (typically up to 80% of value minus current loan)
  3. Set up an equity release or line of credit
  4. Use funds for investment deposit and costs

Tax Considerations

Note: We're not tax advisers. Consult your accountant for specific advice.

  • Interest deductions: Interest on investment loans is tax-deductible
  • Negative gearing: When expenses exceed income, reducing taxable income
  • Depreciation: Building and fixtures can be depreciated
  • Capital gains: 50% discount after 12 months
