Peppermint Grove is a smaller community of 1,597 — about 28% 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 $237,380/year runs 138% 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 $440 covers just 46% of the median $4,167/month mortgage repayment, leaving a $2,260/month gap — investors should only pursue this suburb with a clear capital-growth thesis and sufficient external income to fund the shortfall. At 10 km from the Perth CBD, Peppermint Grove sits inside the high-demand inner ring — properties here compete directly with the city's employment, transport and amenity networks.

Strong buy-and-hold fundamentals: household incomes run 138% above the Western Australia suburb median ($237,380 vs $99,736), and the 10 km CBD distance keeps this suburb in the primary demand zone. In Western Australia, suburbs with this profile have historically clustered in the upper tercile of 10-year capital growth.
Weak cash flow: $440/week rent covers only 46% of the $4,167/month median mortgage — a $2,260/month gap that must be funded from other income. This suburb is a capital-growth play, not a yield play.
Only 68% of dwellings are separate houses (vs 79% WA median) — this is a unit and townhouse market, where cosmetic flips struggle against body-corporate restrictions, thinner after-reno uplift and competing new supply.

That score is driven by a population of 1,597, median household income of $237,380/year and median weekly rent of $440.

The median monthly mortgage repayment in Peppermint Grove is $4,167, or approximately $50,004/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 $440 works out to $1,907/month, covering 46% of the median mortgage repayment of $4,167/month. That leaves a $2,260/month shortfall (around $27,120/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.
