With 18,202 residents, Adelaide is one of South Australia's more populous suburbs — roughly 4.9× the state median of 3,699 — giving it a deep buyer and tenant pool that typically supports higher transaction volumes and shorter average days on market. Household income of $70,980/year is 12% below the South Australia median of $80,964, typically translating into lower entry prices and a tenant base more sensitive to rent increases. Median weekly rent of $400 equates to $1,733/month — about 100% of the median mortgage repayment of $1,733/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits. At 0 km from the Adelaide CBD, Adelaide sits inside the high-demand inner ring — properties here compete directly with the city's employment, transport and amenity networks. Only 3% of dwellings are separate houses (vs 73% state median), so this is a unit-heavy market where body-corporate decisions and strata supply meaningfully shape investor returns.
This suburb suits investors prioritising tenant demand over capital-cost efficiency. Rents are supported by proximity to amenities, but strata fees and entry prices can eat into yield. Local rents consume roughly 29% of household income — a useful sanity check on tenant affordability.

Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
