Gross vs Net Rental Yield: The Number That Actually Matters

Most investors can quote their gross yield. Far fewer can quote their net yield. That gap is the problem, because the first number is the one on the advertisement and the second is the one you actually live with.

Here is the size of the difference. On a realistic investment purchase, a gross yield of 4.7% becomes a net yield of roughly 3.2% once real holding costs are counted. Same property, same rent, same day. About a third of the headline income disappears into costs that were always going to be there. If you buy on the gross number, you are buying on a figure that overstates your return by close to 50%.

Two numbers, defined

Gross rental yield is annual rent divided by the property value, expressed as a percentage. A property bought for $700,000 that rents for $630 a week earns $32,760 a year, which is a gross yield of 4.68%. It is easy to calculate, which is exactly why it is the number that gets advertised.

Net rental yield is what remains after the costs of owning the property, divided by the same value. It deliberately leaves out your mortgage interest, because interest is a financing cost, not a property cost, and it belongs in your gearing position rather than the yield calculation. Net yield answers a narrower and more useful question: before any borrowing, does this asset actually pay to hold?

The same property, run properly

Take that $700,000 purchase at $630 a week and put every real cost on the table.

Line	Amount
Annual gross rent ($630/week)	$32,760
Property management (approx 8%)	($2,620)
Council rates	($1,900)
Water and sewerage (landlord portion)	($800)
Landlord insurance	($1,400)
Maintenance allowance	($2,200)
Vacancy allowance (two weeks)	($1,260)
Net operating income	$22,580

Gross yield: 4.68%. Net yield: 3.23%.

Nothing in that list is exotic. Management sits at roughly 6% to 8% of rent in most markets. Maintenance is budgeted here at about 0.3% of value, which is conservative, and older stock should carry more. A two-week vacancy allowance is prudent even in a tight rental market. None of it is optional, and all of it was knowable before the contract was signed.

Where the gap hides

The costs that quietly erode a "high yield" property are rarely the obvious ones.

Strata is the clearest example. A unit that advertises a 5.3% gross yield can hand back close to half its rental income once a body corporate levy is counted, and buildings with pools, lifts or gyms can carry levies above $1,500 a quarter. That is how a headline high-yield unit lands on a net yield below a plain house.

Land tax is the second trap, because it is charged on unimproved land value rather than the purchase price and it changes by state and by threshold. A property that looks positively geared on paper can move once land tax applies across a growing portfolio.

The point is not that these costs are hidden. It is that gross yield is designed not to show them, and an advertised figure will never volunteer them.

Why the gap matters more in 2026

In a market of double-digit yields, a percentage point of leakage is an irritation. In this market it is the whole decision.

Gross rental yields across the combined capital cities are averaging around 3.5%, recovering slowly from a cyclical low, while the average new investor mortgage rate sits near 6.4%. Vacancy is tight at roughly 1.6% and rents are still growing near 5.9% a year, which supports the income side, but the distance between a 3.5% gross yield and a 6.4% borrowing cost means the net number is no longer a detail. It is the difference between a property you can comfortably hold through a soft patch and one that quietly drains cash every month it is owned.

Buying on gross yield in this environment is not optimism. It is a miscalculation with a monthly cost.

How we run it

At CQB Partners, the net number is modelled before a property is shortlisted, not after it is bought. Every line above is estimated for the specific asset, in the specific location, at the specific price, and the result is tested against the investor's mapped strategy under the Yield Security key. A property that does not clear a defensible net yield does not proceed on a yield mandate, regardless of how the gross figure reads on the listing.

That is the difference between sourcing a property and modelling one. The gross number sells the property. The net number tells you whether it belongs in your portfolio.

The number even this one misses

Net yield fixes the first blind spot. It does not fix the second.

Net yield is still a single-year snapshot. It says nothing about capital growth, nothing about when your money goes in and comes back out, and nothing about the actual return on the cash you personally invested across the full hold. Two properties can share an identical net yield and deliver completely different outcomes once time and growth are counted.

The number that captures all of that is the internal rate of return, and it is the one most buyer's agents never put in front of a client. That is the subject of the next piece in this series.
