Allendale North is a smaller community of 162 — about 4% of the South Australia suburb median (3,699) — so investors should factor in the narrower buyer pool and longer average time-on-market. Households here earn $87,724/year on average — 8% above the SA suburb median of $80,964 — a modest premium that supports resilient owner-occupier demand. Median weekly rent of $319 equates to $1,382/month — about 97% of the median mortgage repayment of $1,428/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits. Allendale North is 78 km from Adelaide, so the local market tracks regional employment and lifestyle drivers more than CBD-driven commuter demand. Separate houses make up 94% of dwellings — 21 percentage points above the South Australia median of 73% — pointing to a family-oriented, land-rich market where value is concentrated in the underlying block.
