Gross yield is the number agents quote in marketing material. Net yield is the number that determines whether a property actually pays for itself. The gap between the two is where most investor disappointments are born.

Before signing a contract, every investor should work through the full holding cost stack. Not an estimate. Not a back-of-envelope figure. A line-by-line calculation that accounts for every recurring cost and a realistic vacancy allowance. A property that looks attractive at 5.2% gross yield can produce negative cash flow once the real numbers are applied.

## Gross Yield: The Starting Point, Not the Answer

Gross yield is calculated as annual rent divided by purchase price, expressed as a percentage. A property purchased for $550,000 returning $500 per week in rent produces a gross yield of 4.73%.

**Calculation:** ($500 x 52) / $550,000 = 4.73%

This figure is useful for comparing properties quickly across a suburb or market. It tells you nothing about what you will actually keep after costs. Agents use gross yield because it is the highest number available and requires no disclosure of expenses.

Net yield strips out the costs of ownership. For most Australian residential properties, those costs reduce gross yield by 1.5 to 2.5 percentage points depending on property type, age, location, and financing structure.

## The Full Holding Cost Stack

### Property Management Fees

Property managers typically charge between 7% and 12% of gross rent in Australian capital cities, plus a letting fee of one to two weeks' rent per new tenancy. On $26,000 annual rent, a 9% management fee costs $2,340 per year before the letting fee. This is the most predictable cost in the stack and the one investors most commonly underestimate by using the lower end of the range.

### Council Rates

Council rates vary by local government area and property value. In Brisbane, rates for a median-priced house run roughly $1,800 to $2,800 per year. In Sydney and Melbourne, the range is wider. Rates are not negotiable and increase annually. They are also not recoverable from tenants in residential leases.

### Water and Utilities

In most states, landlords pay water supply charges and tenants pay consumption. In Queensland, landlords can pass on water consumption costs if the property is individually metered and water-efficient. In New South Wales and Victoria, the rules differ. Budget $600 to $1,200 per year for water rates depending on state and property type.

### Insurance

Landlord insurance covers building, landlord contents, loss of rent, and tenant default. Annual premiums for a standalone house typically range from $1,500 to $2,800 depending on location, construction type, and flood or cyclone exposure. Properties in high-risk flood zones or cyclone-prone areas in Queensland can attract premiums materially above this range. Getting an insurance quote before exchange is not optional. It is part of the due diligence process.

### Strata Fees

For units and townhouses, body corporate levies add a layer of cost that varies enormously. A well-managed low-rise block might levy $3,000 to $5,000 per year. An older high-rise with a pool, lift, and deferred maintenance can levy $8,000 to $15,000 or more. The sinking fund balance matters as much as the current levy. A body corporate with a depleted sinking fund and ageing infrastructure is a liability that will eventually produce a special levy. Reviewing the last two years of meeting minutes and the sinking fund report is the only way to assess this risk.

### Maintenance and Repairs

A common rule of thumb is to budget 1% of property value per year for maintenance. On a $550,000 property, that is $5,500. For a newer property in good condition, actual costs may be lower. For a property built before 1980 with original plumbing, wiring, or roofing, actual costs will be higher. Maintenance is the most variable item in the holding cost stack and the one most likely to produce cash flow surprises in years two through five.

### Land Tax

Land tax is levied by state governments on the unimproved value of investment properties. Each state has different thresholds, rates, and exemption rules. In New South Wales, land tax applies above a threshold of around $1,075,000 (2026 figure, adjusted annually). In Victoria, the threshold is much lower at $300,000. Queensland applies land tax above $600,000 for individuals. Investors holding multiple properties in the same state can breach thresholds even if individual properties sit below them. Land tax is often overlooked by investors purchasing their first investment property and then becomes a recurring cost as the portfolio grows.

### Interest Costs

For most investors, the largest holding cost is mortgage interest. At a variable rate of 6.5% on an 80% LVR loan against a $550,000 purchase, the interest component in year one is approximately $28,600. This dwarfs every other cost in the stack. The relationship between interest rates and rental income determines whether a property is positively or negatively geared. At current rate levels, most Australian residential properties purchased in the last three years are negatively geared.

### Vacancy Allowance

Vacancy is a cost that does not appear on any invoice but is real. A property vacant for three weeks per year represents a 5.8% reduction in gross rental income. In markets with low vacancy rates, this might be conservative. In oversupplied markets or in properties with seasonal demand, vacancy can run higher. Budget at least two to three weeks per year as a baseline and adjust for local conditions.

## Running the Net Yield Calculation

Using the $550,000 example with $500 per week rent, here is what the net yield calculation looks like:

**Gross annual rent:** $26,000

**Less holding costs:**
- Property management (9%): $2,340
- Council rates: $2,200
- Water rates: $900
- Landlord insurance: $1,800
- Maintenance and repairs (0.8%): $4,400
- Vacancy allowance (3 weeks): $1,500

**Total non-finance costs:** $13,140

**Net rental income before interest:** $12,860

**Net yield before interest:** 2.34%

**Annual interest at 6.5% on $440,000 loan:** $28,600

**Annual cash deficit:** $15,740

This is a negatively geared property producing a cash shortfall of over $300 per week. Whether that is acceptable depends on the investor's tax position, capital growth expectations, and cash reserves. The point is that the 4.73% gross yield headline obscured a $15,740 annual cash requirement.

## Why Cheaper Properties Can Still Have Weak Cash Flow

A $320,000 regional property returning $380 per week looks attractive at 6.17% gross yield. Run the same analysis and the picture can shift.

Older properties in regional markets often carry higher maintenance costs per dollar of value. Insurance premiums in flood-prone or cyclone-exposed areas can be two to three times the metropolitan equivalent. Property managers in thin rental markets may charge higher fees and have less leverage to fill vacancies quickly. Council rates in smaller local government areas are not always lower. And if the property sits on a septic system, has a corrugated iron roof, or has original electrical wiring, the 1% maintenance rule understates the likely cost.

A $320,000 property with $6,000 in insurance, $4,500 in maintenance, $3,200 in management fees, $2,000 in council rates, and a four-week vacancy allowance produces net rental income of roughly $4,100 before interest. That is a pre-finance net yield of 1.28%. The gross yield headline was 6.17%.

Price alone does not determine cash flow quality. Cost structure does.

## What to Check Before Committing

Before making an offer on any investment property, the following checks are worth completing:

- Get an insurance quote for the specific property. Do not use a generic estimate.
- Request the last two years of body corporate financials for any strata property.
- Check the council rates notice or ask the agent for the current rates figure.
- Research local property management fee structures by calling two or three local agencies.
- Assess the property's age, construction type, and maintenance history against a realistic annual cost.
- Calculate land tax liability based on your existing portfolio and the relevant state threshold.
- Model the cash flow at current interest rates, not at a rate you hope to negotiate.
- Apply a vacancy allowance based on suburb-level vacancy data, not the agent's optimism.

PropertyLens publishes suburb-level rental yield data, vacancy trends, and supply pipeline analysis for Brisbane, Sydney, Melbourne, and the Gold Coast. The platform draws on public sales records, ABS demographic data, and council planning information to provide context that goes beyond the headline yield figure. When assessing whether a suburb's rental market is tightening or softening, having access to days-on-market trends and rental supply data changes the quality of the vacancy assumption you build into your model.

## The Cash Flow Model Is Not Optional

Negative gearing can be a deliberate and rational strategy for investors in higher tax brackets who are confident in long-term capital growth. It is not a strategy that works by accident. Running the full holding cost calculation before purchase is the difference between a deliberate position and an unpleasant surprise.

The investors who get into difficulty are rarely those who modelled the costs and accepted the cash shortfall knowingly. They are the ones who relied on the gross yield figure, assumed costs would be modest, and discovered the reality in year two when the hot water system failed, the tenancy ended, and the insurance renewal arrived.

Run the numbers before you sign. All of them.
