Investment property loans in Australia

A sound investment property decision begins with the figures. This guide explains how rental yield, gearing, loan structure and equity work in Australia, and links to the calculators for testing a proposed purchase.

Key concepts in investment property finance

Investment lending builds on the same structures described in the guide to Australian home loan types. Investors comparing locations may also refer to the suburb guides.

01

Rental yield

Rental yield is annual rent expressed as a percentage of the property's value. Gross yield ignores costs. Net yield, calculated after rates, insurance, management and maintenance, is the figure that services the loan.

Gearing

Negative gearing means the property costs more to hold than it earns. From 1 July 2027, that loss can be offset against other income only for new builds and for properties held before 7:30pm AEST on 12 May 2026. For other established properties the loss is carried forward. Positive gearing means the rental income covers the holding costs.

Interest-only lending

Most investors begin with an interest-only loan, which offers lower repayments, maximum deductible interest and preserved cash flow. The trade-off is a higher rate and no reduction in debt, so the investment strategy must justify the additional cost.

Equity as a deposit

Where a home has grown in value, usable equity (up to 80% of value, minus the existing loan) can fund an investment deposit without the need to save a new one. Most Australian property portfolios begin in this way.

Worked example

Weekly holding costs of a $650,000 investment unit

Illustrative only: an 80% LVR interest-only loan at 6.4%, rented at $560/week, before tax effects and depreciation. Consider modelling your own scenario in the calculator.

Rent (gross)+$560 / week
Loan interest ($520,000 IO at 6.4%)−$640 / week
Property management (7%)−$39 / week
Rates, insurance, maintenance allowance−$95 / week
Pre-tax holding cost−$214 / week

The $214 a week is the central consideration. Negative gearing reduces it at tax time, but the purchase is worthwhile only if capital growth, or future rent, exceeds the shortfall. The investment property calculator, and an experienced broker, can test this calculation. Current investor pricing is summarised in the interest rates overview.

Investment property loans: frequently asked questions

How much deposit is required for an investment property?

Most lenders require 10 to 20% for investment lending, and the most competitive rates apply at 20% or more (80% LVR or below). Many investors use equity in an existing property instead of cash. Usable equity is typically 80% of the home's value minus the amount owing.

What is a good rental yield in Australia?

Gross yields on houses in the capital cities have historically ranged around 3 to 5%, with units and regional properties often higher. High yield and high growth are rarely found in the same postcode. The appropriate balance depends on whether the main constraint is cash flow or time in the market.

How does negative gearing work?

If deductible costs (loan interest, management, maintenance, depreciation) exceed the rent received, the property makes a tax loss. Under changes announced in the 2026-27 Budget, from 1 July 2027 that loss can be offset against other income only for new builds and for properties held before 7:30pm AEST on 12 May 2026. For established properties bought after that time, the loss is carried forward against future residential property income and gains. A registered tax agent can confirm how the rules apply.

Are investment loan rates higher than owner-occupier rates?

Yes, typically by around 0.2 to 0.6%, and interest-only lending adds a further margin. Regulators require banks to hold more capital against investor lending. For the same reason, investment loans are the segment in which a broker most often obtains a rate below the advertised rate.

Can an existing home be rented out when buying a new one?

Yes, and it is often the simplest way to begin investing. The existing loan can usually be converted to investment purposes, the interest becomes deductible, and the equity helps fund the next purchase. It is advisable to obtain tax advice on the structure before moving rather than afterwards.
