The typical mortgage payment is listed at $2,200 per month, and mortgage costs equal 19.8% of household income, below the level usually associated with mortgage stress. Housing choice is concentrated in 100.0% separate houses, including 50.3% with 4 or more bedrooms and 42.6% with 3 bedrooms. The outright ownership rate is lower than the mortgage rate, 45.7% versus 47.6%, because the suburb combines long-term owners with affluent households still financing substantial homes.
For Buyers
The typical mortgage payment is listed at $2,200 per month, and mortgage costs equal 19.8% of household income, below the level usually associated with mortgage stress. Housing choice is concentrated in 100.0% separate houses, including 50.3% with 4 or more bedrooms and 42.6% with 3 bedrooms. The outright ownership rate is lower than the mortgage rate, 45.7% versus 47.6%, because the suburb combines long-term owners with affluent households still financing substantial homes.
For Investors
Investment conditions are shaped by limited rental participation rather than a large tenant pool. Only 6.0% of households rent, well below the 45.7% owning outright, while the weekly rent is $500 and vacancy is 5.2%. Rent growth of 32.3% points to stronger recent rental momentum than the slow 0.36% annual population trend. The 68 development applications recorded over 12 months include outbuildings and alterations, so activity appears more focused on existing properties than a large pipeline of new dwellings. With 85.6% of residents staying at the same address and 14.4% turnover, the market is less mobile than a typical high-churn rental suburb.

Tenure
Aldgate's housing market is expensive, spacious and overwhelmingly detached. The stock is 100.0% separate houses, with 50.3% containing 4 or more bedrooms and 42.6% containing 3 bedrooms. Tenure is split between 45.7% owned outright, 47.6% mortgaged and just 6.0% rented. The mortgage share is higher than outright ownership by 1.9 percentage points, indicating that buyers are still using finance despite high household resources. Mortgage costs equal 19.8% of household income and rent costs 19.5%, both below stress thresholds, which helps explain the suburb's strong retention and low rental share.

Real income growth is 8.9% and rent growth is 32.3%, which can sustain property demand even as household composition changes.

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), SA Department for Housing and Urban Development (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.
