Leinster is a smaller community of 716 — about 13% of the Western Australia suburb median (5,605) — so investors should factor in the narrower buyer pool and longer average time-on-market. Median household income of $133,224/year runs 34% above the Western Australia suburb median of $99,736, indicating strong purchasing power and the type of demographic profile that tends to sustain premium property prices through market cycles. Weekly rent of $46 covers just 38% of the median $520/month mortgage repayment, leaving a $321/month gap — investors should only pursue this suburb with a clear capital-growth thesis and sufficient external income to fund the shortfall. Leinster is 630 km from Perth, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand. Only 51% of dwellings are separate houses (vs 79% state median), so this is a unit-heavy market where body-corporate decisions and strata supply meaningfully shape investor returns.

That score is driven by a population of 716, median household income of $133,224/year and median weekly rent of $46. Whether it fits your portfolio depends on whether you are targeting cash flow, capital growth, or a value-add renovation — all three are scored with suburb-specific numbers elsewhere on this page.

Together these shape both owner-occupier and tenant demand and are the factors we weight most heavily in the suburb's investment score.
Leinster has a usual resident population of approximately 716, compared with a Western Australia suburb median of 5,605 — placing it in the lower half of the state's suburbs by size. Population is the clearest proxy for market depth: more residents mean more transactions and typically a shorter average days-on-market on resale.
Leinster sits 630 km straight-line from the Perth CBD. This is a regional market where CBD distance is only indicative — local industry diversity and commute alternatives matter more.
The most recent census recorded a median weekly rent of $46 in Leinster, equating to approximately $2,392/year in gross rental income (state median $350/week).

The median monthly mortgage repayment in Leinster is $520, or approximately $6,240/year (vs $1,902/month state median). Stress-test your own borrowing at rates 1–2 percentage points above today's to make sure you can still service the loan through an RBA tightening cycle.
A median weekly rent of $46 works out to $199/month, covering 38% of the median mortgage repayment of $520/month. That leaves a $321/month shortfall (around $3,852/year before tax benefits), so a typical owner-occupier-priced property here is negatively geared. Actual cash flow depends on your deposit, loan terms, ownership costs and marginal tax rate — run the full numbers in our rental yield calculator.
The main risks are a thin buyer pool (716 residents), interest-rate sensitivity on the $520 median mortgage, the broader Western Australia market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
