4,592 residents places Swanbourne squarely in the middle of the Western Australia suburb size distribution (state median 5,605), with market depth comparable to most WA localities. Median household income of $177,736/year runs 78% 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. Median rent of $470/week (~$2,037/month) covers only 58% of the median mortgage of $3,504/month — the remaining $1,467/month must be funded from other income, so this suburb tilts toward capital growth rather than yield. At 9 km from the Perth CBD, Swanbourne sits inside the high-demand inner ring — properties here compete directly with the city's employment, transport and amenity networks.
Middle-ring locations like this one historically reward patient holders — focus on homes near catchment-zone schools and major transport. Local rents consume roughly 14% of household income — a useful sanity check on tenant affordability.

That score is driven by a population of 4,592, median household income of $177,736/year and median weekly rent of $470. 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.
Swanbourne has a usual resident population of approximately 4,592, compared with a Western Australia suburb median of 5,605 — placing it in the lower half of the state's suburbs by size.

The median monthly mortgage repayment in Swanbourne is $3,504, or approximately $42,048/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 $470 works out to $2,037/month, covering 58% of the median mortgage repayment of $3,504/month. That leaves a $1,467/month shortfall (around $17,604/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 (4,592 residents), interest-rate sensitivity on the $3,504 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.
