Kilburn's population of 5,633 sits 52% above the South Australia suburb median of 3,699, giving it a wider tenant and buyer catchment than the average SA locality. Kilburn's median household income of $61,308/year is 24% below the South Australia suburb median ($80,964) — this is an affordability play where returns lean on yield and patient capital growth rather than demographic premium. Rent of $270/week (79% coverage of the $1,472/month median mortgage) leaves a gap of roughly $302/month that a typical investor bridges with negative gearing, depreciation and capital growth. At 8 km from the Adelaide CBD, Kilburn sits inside the high-demand inner ring — properties here compete directly with the city's employment, transport and amenity networks. Only 42% 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 long-term investors looking for a balance of rental yield and capital growth. Schools and transport underpin family demand. Local rents consume roughly 23% of household income — a useful sanity check on tenant affordability.

Kilburn has a usual resident population of approximately 5,633, compared with a South Australia suburb median of 3,699 — placing it in the upper half of the state's suburbs by size.

The median monthly mortgage repayment in Kilburn is $1,472, or approximately $17,664/year (vs $1,616/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 $270 works out to $1,170/month, covering 79% of the median mortgage repayment of $1,472/month. That leaves a $302/month shortfall (around $3,624/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.
The main risks are interest-rate sensitivity on the $1,472 median mortgage, below-median household incomes ($61,308 vs $80,964 state median), the broader South Australia market cycle. Each of these is covered in the Risk Factors section above with suburb-specific numbers rather than generic warnings.
