Property Investing, Done Right.

Investment property finance is more complex than owner-occupier lending. Loan structure, interest-only periods, offset accounts and rental income treatment all affect your outcome significantly.

Quick Answer

How should I structure finance for an investment property in Australia?

Investment finance is structured very differently to owner-occupier loans. Interest-only on the investment portion improves cash flow and maximises tax-deductible interest (ATO), while offset accounts concentrate savings against non-deductible owner-occupier debt first. Rental income is typically assessed at 70–80% to buffer vacancy and expenses. Ownership name (individual, trust, SMSF) materially affects land tax, CGT and future borrowing capacity — the wrong structure costs tens of thousands across a portfolio. A depreciation schedule ($600–$800 one-off) usually unlocks $3K–$8K/yr in deductions.

01
Interest-only loans for investors
Interest-only loans reduce your repayments during the interest-only period — you pay only the interest, not the principal. This improves cash flow and maximises negative gearing benefits. Most lenders allow 5-year interest-only periods for investors, with some offering up to 10 years.
02
How rental income is assessed
Most lenders use 70–80% of your rental income when calculating serviceability — they apply a buffer to account for vacancy and expenses. Some lenders are more generous with rental income assessment, which can significantly increase your borrowing capacity.
03
Loan structure and offset accounts
For investors, structuring your loan correctly is crucial. An offset account on your investment loan reduces interest while keeping funds accessible — important for tax purposes. Using equity in your existing home as security for an investment loan is also a common strategy.
04
Negative gearing implications
If your investment property expenses (including loan interest) exceed your rental income, you have a negatively geared property. This loss is deductible against your other income, reducing your tax. Your lender and specialist consider this when assessing your overall position.
05
Portfolio lending — multiple properties
If you already own investment properties, lenders assess your entire portfolio — total debt, total rental income, total expenses. Some lenders cap the number of investment properties they will finance. A specialist who works with investors knows which lenders have portfolio-friendly policies.

What people get wrong

Not separating investment debt from personal debt
Mixing investment and personal borrowings in one loan can create tax complications. Investment loan interest is generally deductible; personal loan interest is not. Keep them separate from the start.
Choosing interest-only without understanding the switch
At the end of your interest-only period, repayments jump significantly as you begin paying principal. Make sure you understand what your repayments will look like when the interest-only period ends.
Using redraw instead of offset for investment properties
Redrawing from an investment loan can change the tax deductibility of the interest. Using an offset account achieves similar interest savings without this risk. Always discuss with your accountant.
Not getting pre-approval before making an offer
Investment property markets move fast. Having finance pre-approved means you can act quickly and make unconditional offers — a significant advantage when competing against other buyers.

💡 Structure before you buy

The structure of your investment loan affects your tax position, borrowing capacity for future purchases, and overall return. Getting specialist advice before you buy — not after — is one of the most important things an investor can do. A specialist will work with your accountant to get the structure right from the start.

Frequently asked questions

With interest-only, you pay only the interest each month — your loan balance stays the same. With principal and interest, you pay both — your balance reduces over time. Interest-only has lower repayments but you build no equity through repayments.

Yes — if you have sufficient equity in your existing property, you can use it as security for an investment loan without needing a cash deposit. The lender assesses the combined LVR across both properties.

Most lenders accept 70–80% of your expected gross rental income. Some specialist lenders use higher percentages for experienced investors with strong rental histories. Your specialist will find the lender with the most favourable rental income policy for your situation.

Negative gearing reduces your taxable income by the amount of your net rental loss. Whether it makes overall financial sense depends on your tax rate, the property's capital growth prospects, and your cash flow position. Always discuss with your accountant.

Most lenders require at least 10% deposit for investment properties, plus costs. If you have equity in an existing property, this can substitute for a cash deposit. Some lenders will lend 90% for investment with LMI, though this becomes more restrictive for investment properties.
