For Investors
Heidelberg Heights has a large renter base, with 42.4% of households renting compared with 24.1% owning outright. Weekly rent is $381, creating an established tenant market, although the 10.8% vacancy rate is high and may mean leasing conditions vary between properties. Three-bedroom homes make up 46.4% of the housing stock, which aligns with demand from households seeking more space than a small apartment. Development activity is also material, with 24 applications recorded over 12 months, including examples for 6-lot and 7-lot subdivisions. Compared with the suburb's earlier price base, the current value is stronger, but investors should allow for competition from new subdivision supply and vacancy risk.

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), Valuer-General Victoria (house prices), 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.
