Mount Sheridan is a smaller community of 23 — about 0% 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 $168,948/year runs 69% 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. The median weekly rent of $85 translates to approximately $4,420/year in gross rental income, setting the upper bound on yield before vacancy, rates, insurance and maintenance. Mount Sheridan is 332 km from Perth, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand. Only 55% 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.
