Rental yield on a Perth new build.
Yield is the rent divided by what you actually paid. A new build keeps the cost side honest, because the build price is fixed and current. Here is how to model it with real Perth numbers.

Rental yield is annual rent divided by total cost. On Perth new builds, gross yields commonly land in a 4% to 6% band against the build cost, with dual-income properties going higher. The Property Plug publishes the real all-in build cost for 102 suburbs, so you model yield on the number you actually pay, not a builder teaser.
Gross yield versus net yield
Gross yield is the headline figure: annual rent divided by total cost. Net yield is the honest figure: it subtracts your holding costs such as council rates, water rates, insurance, property management and maintenance, typically 1% to 1.5% off the gross. For a new build, maintenance runs near zero for the first several years and the builder warranty covers structural defects, so the gap between gross and net stays tight early on. That early-years advantage is one reason investors favour new over established stock.
- Find the build all-in. Take the design's from-price and add the suburb's real siteworks. For Horizon in Baldivis that is $314,760 plus $20,768, so $335,528.
- Add land. Land is a separate contract. Your true total cost is build all-in plus the land price, and that total is what your net yield is measured against.
- Apply the rent. Multiply the achievable weekly rent by 52. At $620 per week that is $32,240 a year.
- Divide. Annual rent divided by total cost, times 100, is your gross yield. Subtract holding costs for net yield.

| Suburb | Siteworks | Build all-in | Indicative rent | Gross yield on build |
|---|---|---|---|---|
| Baldivis | $20,768 | $335,528 | $620/wk | 9.6% |
| Wellard | $20,916 | $335,676 | $610/wk | 9.4% |
| Alkimos | $26,822 | $341,582 | $630/wk | 9.6% |
| Piara Waters | $21,236 | $335,996 | $650/wk | 10.1% |
Yield against build cost only. Add land for true net yield. Rents are indicative assumptions, not guarantees. Illustrative and general information only.
Want a higher yield? Add a second rent.
A single tenancy caps your gross yield at one rent. A granny flat or dual-key design collects two. As an indicative example, the Haven granny flat builds from $238,268 in Baldivis, adding a second rent on top of the main home. See the dual-income guide and dual-key homes. New builds also unlock a fresh depreciation schedule that lifts after-tax cashflow, and a turnkey contract means it lets the day it hands over.

What is a good rental yield in Perth in 2026?
Gross yields on Perth new builds commonly sit in a 4% to 6% band against the build cost, with dual-income properties reaching higher. As an indicative example, Horizon building from $335,528 in Baldivis at $620 per week is about 9.6% gross on build cost. Figures are illustrative, not a forecast.
How do I calculate rental yield?
Gross yield equals annual rent divided by total cost, times 100. Net yield subtracts holding costs such as rates, insurance, management and maintenance. For a new build the cost side is your build all-in plus land, and the rent side is the current achievable market rent.
Does a new build yield more than an established home?
Often yes on a like-for-like price, because the build cost is fixed and current, depreciation improves after-tax cashflow, and maintenance is low for years. Established homes hide deferred capital works that erode net yield.
Which Perth suburbs have the best yield for new builds?
Outer growth corridors such as Baldivis, Wellard, Alkimos and Piara Waters pair lower land and build costs with solid rental demand. We publish the real siteworks figure for every one so you can compare the all-in build cost directly.
Is rental yield the only number that matters?
No. Yield measures income return, not capital growth or after-tax cashflow. Model both, and stress-test your loan. We are paid by the builder, never by you.
