Darch's population of 7,347 sits 31% above the Western Australia suburb median of 5,605, giving it a wider tenant and buyer catchment than the average WA locality. Median household income of $124,956/year runs 25% 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 weekly rent of $460 equates to $1,993/month — about 100% of the median mortgage repayment of $2,000/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits. 15 km from Perth places Darch in the middle commuter belt, close enough for daily trips by car or rail but at a materially lower price point than inner suburbs.
Middle-ring locations like this one historically reward patient holders — focus on homes near catchment-zone schools and major transport. Local rents consume roughly 19% of household income — a useful sanity check on tenant affordability.
