Rental yield Perth numbers decide whether an investment pays for itself. Yet many buyers compare yields the way they compare paint colours, without reading the label. In other words, gross and net yield are different numbers that tell different stories.
This guide explains both, with a worked example you can copy. No jargon, just arithmetic.
Numbers first, feelings second.

Rental Yield Perth: The Gross Number
Gross yield is the simple fraction every listing quotes. First, take the annual rent. Then, divide it by the purchase price and multiply by one hundred.
For example, a home renting at four hundred dollars a week earns twenty thousand eight hundred dollars a year. A four hundred thousand dollar purchase price therefore gives a gross yield of about five point two percent. However, that number ignores every cost you will actually pay.
The Net Number, Where Truth Lives
Net yield subtracts the real costs, such as management fees, rates, insurance, levies, repairs and vacancy weeks. As a result, a five point two gross can shrink to a four percent net in a flash.
Two identical gross yields can produce wildly different nets. For instance, an apartment with high levies may net far less than a house with none. Because of that, always compare nets, not grosses.
The Costs New Investors Forget
- Management fees, often a slice of every rent payment.
- Rates, water service charges and strata levies.
- Insurance, including landlord cover.
- Repairs, which average out over the years even in good years.
- Vacancy, which is rent you never see.
Add vacancy at two weeks per year as a starting point. However, some Perth pockets run tighter and some looser. In addition, a free rental appraisal gives you a realistic rent figure rather than a hopeful one.
Yield Versus Growth, The Real Choice
High yield suburbs usually offer slower capital growth, and that is a fair trade for cash flow investors. Meanwhile, low yield blue chips usually bank on growth instead. Neither is wrong, but mixing them up is.
Match the strategy to your finances, not to your ego. As a result, a five percent net that you can hold comfortably beats a seven percent gross that starves you. Overall, yield is oxygen, and growth is the prize, so choose the mix you can actually breathe on.
Do This Before Any Offer
Write down the real rent, the real costs and the real vacancy for that specific property. Then, and only then, compare it with alternatives.
