Kojaneerup South 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. Household income of $84,500/year is 15% below the Western Australia median of $99,736, typically translating into lower entry prices and a tenant base more sensitive to rent increases. The median weekly rent of $76 translates to approximately $3,952/year in gross rental income, setting the upper bound on yield before vacancy, rates, insurance and maintenance. Kojaneerup South is 370 km from Perth, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand. Only 23% 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.
