For Investors
Alexander Heights presents a lower-rental, established investment profile: 16.1% of occupied dwellings are rented, weekly rent is $360 and vacancy is 4.0%. That combination can limit the depth of the tenant pool compared with suburbs with higher rental shares, although the detached-house base may appeal to families seeking 4 or more bedrooms, which account for 68.5% of stock. Development activity is recorded at 0 projects in the past 12 months, reducing near-term construction competition but also limiting new product. Forecast growth is 0.02% annually and is driven primarily by overseas migration, so investors should prioritise tenant demand and maintenance rather than assume rapid capital growth. A gross yield cannot be calculated without a current median house price.

The trajectory is labelled Aging, with the senior share up 5.5 points and the young share down 1.9 points.

How to read these comparisons
Phrases like "above the national average" reference the unweighted median across Australian suburbs with more than 1,000 residents, not population-weighted national figures. Suburb-level medians are more useful for ranking suburbs against each other; ABS census headlines are population-weighted (so dominated by Sydney and Melbourne) and can read very differently.
Current baseline (refreshed 2026-05-10): median age 40, university-educated 30.1%, born overseas 21.6%, average household size 2.5 people.
Data sources: ABS 2021 Census (demographics, income, tenure), state education open registers (school locations), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
