4,429 residents places Glen Alpine squarely in the middle of the New South Wales suburb size distribution (state median 5,325), with market depth comparable to most NSW localities. Median household income of $138,788/year runs 42% above the New South Wales suburb median of $97,552, indicating strong purchasing power and the type of demographic profile that tends to sustain premium property prices through market cycles. Median weekly rent of $570 equates to $2,470/month — about 114% of the median mortgage repayment of $2,167/month — meaning rental income covers most of a typical owner's repayment and this is a genuine cash-flow suburb before tax benefits. At 47 km from Sydney, Glen Alpine is an outer-metro location where buyers are typically trading commute time for floor space and a lower entry price. Separate houses make up 96% of dwellings — 20 percentage points above the New South Wales median of 76% — pointing to a family-oriented, land-rich market where value is concentrated in the underlying block.
This suburb suits yield-focused investors who are comfortable with lower liquidity. Employment concentration and local population trends matter more here than in metro markets. Local rents consume roughly 21% of household income — a useful sanity check on tenant affordability.
