Investment Property Expenses Checklist Australia

Short answer

A useful investment-property estimate starts with actual rent and current annual bills. Collect vacancy, management, council and water rates, insurance, strata, maintenance, land tax and loan figures before comparing properties.

Keep three groups separate:

1. recurring property costs used in net rental yield;
2. finance costs used in pre-tax cash flow; and
3. one-off buying and selling costs.

Use the Rental Yield Calculator after gathering the figures. Its net yield uses the annual property costs entered. Its cash-flow result then subtracts an interest-only loan-cost estimate. It does not provide tax advice or model principal repayments.

The checklist

The list is a starting point. Property type, age, location, lease terms, ownership and state rules can create other costs.

Rent and vacancy

Use the rent actually received where available. If the property is not yet leased, record the source and date of any rental estimate and test a lower figure.

Vacancy is an assumption, not a forecast. A 2% annual allowance is about one week of gross rent. A 4% allowance is about two weeks. Turnover can also involve advertising, letting, cleaning or compliance costs that a simple percentage does not capture.

ASIC Moneysmart warns that there may be periods when an investor has to cover costs without a tenant. A high advertised rent should not be treated as 52 guaranteed paid weeks.

Annual operating costs

Management fees

Check whether the quoted percentage includes GST and whether it applies to collected rent. Record separate letting, advertising, statement, inspection or tribunal fees if they are material.

Council and water rates

Annualise the latest notices. Separate owner charges from amounts a tenant may pay under the applicable tenancy rules and lease. Do not assume water treatment is identical across states.

Insurance

Use a current quote or renewal amount. Building insurance, landlord cover and strata insurance are different. A strata levy may fund the building policy while the lot owner still needs other cover.

Strata or body corporate

Use the current administrative and capital works levies. Read recent records for special levies or major works. A known one-off special levy should be shown separately rather than smoothed into a permanent annual assumption without explanation.

Repairs and maintenance

A zero maintenance allowance is rarely a neutral assumption. Use recent invoices, an inspection report and the condition of roofs, services, appliances, gardens, pools and common property.

The calculator accepts either a fixed annual amount or a percentage of purchase price. A property-specific fixed estimate is usually easier to explain than a broad percentage.

Land tax needs ownership information

Land tax generally depends on taxable land value, state, ownership type, exemptions and the owner's other landholdings. It is not calculated from the property's market price alone.

Use the Land Tax by State tool with the relevant ownership details, then enter the indicative annual result in the yield calculator. Check the assessment and current revenue-office rules before relying on an exemption or owner classification.

Financing cost is not net yield

Net rental yield is useful for comparing the property's operating return before financing. Loan interest belongs in a separate leveraged cash-flow result.

The Rental Yield Calculator approximates annual interest as:

Loan balance x annual interest rate

That is an interest-only estimate. A principal-and-interest repayment is higher because it also reduces the loan balance. Use the Mortgage Repayment Calculator for a scheduled repayment estimate.

Loan fees, offsets, redraw, rate changes and daily interest calculations can also change actual cash flow.

Depreciation and tax deductions are separate

Depreciation is non-cash, so the Rental Yield Calculator does not subtract it from cash net yield or pre-tax cash flow.

The Australian Taxation Office separates expenses that may be immediately deductible, deductible over time, private, capital or otherwise not deductible. Tax treatment also depends on ownership, use of borrowed funds, private use and whether the property is rented or genuinely available for rent.

Do not treat a cash expense as fully recovered because it may be deductible. A deduction generally reduces taxable income; it is not a dollar-for-dollar reimbursement. Use the Negative Gearing Calculator only as a general scenario and check the actual treatment with a registered tax agent.

One-off costs belong in a separate calculation

Stamp duty, conveyancing, searches, inspections, lender establishment fees and moving costs affect the cash needed to buy. They do not belong in an annual net rental yield unless the chosen methodology explicitly annualises acquisition costs and explains the period.

Use the Property Purchase Cost Calculator for buying costs. Use the Property Selling Costs Calculator for an indicative sale scenario.

Worked example

Assume an investment property has:

• purchase price: $650,000;
• rent: $600 per week;
• vacancy allowance: 2%;
• management fee: 7% of collected rent;
• council rates: $2,000;
• water rates: $800;
• insurance: $1,200;
• maintenance: $2,000;
• land tax: $1,500;
• loan balance: $520,000; and
• interest rate: 6.2%.

Gross annual rent is $31,200. After the vacancy allowance, effective rent is $30,576.

The entered annual property costs total about $9,640, including about $2,140 of management fees. Net income before interest is about $20,936, producing a net yield of about 3.22%.

The interest-only estimate is $32,240 a year. After that amount, the modelled pre-tax cash flow is a shortfall of about $11,304 a year, or about $217 a week.

This example is arithmetic, not a recommendation. It excludes principal repayments, buying costs, selling costs, tax outcomes, depreciation and capital growth.

Common omissions

• Using advertised rent without a vacancy allowance.
• Entering a management percentage but forgetting letting and advertising fees.
• Omitting water, insurance or land tax because they are paid less often than monthly.
• Treating strata as one current quarter without checking the annual budget.
• Using zero for maintenance on an older property.
• Calling an interest-only estimate the actual mortgage repayment.
• Deducting depreciation as if it were cash paid.
• Mixing stamp duty into annual property expenses.
