A current median house price is not stated, so monthly holding costs and housing structure are useful starting points. The typical mortgage repayment is $2,208 per month, with mortgage costs at 21.3% of household income, higher than the 19.2% rent-to-income measure. Buyers are primarily choosing detached stock: 91.9% of dwellings are separate houses, compared with 1.8% apartments, and 68.8% have four or more bedrooms. The 44.6% mortgage share is higher than the 11.9% renting share, indicating a market led by established owner-occupiers rather than short-term tenants. Household income at the 90.5 percentile is above the national middle, but buyers should still compare recent sales by street and dwelling condition.

For Investors
Duncraig presents a lower-turnover investment profile, with only 11.9% of households renting compared with 86.1% owning outright or with a mortgage. Weekly rent is $460 and vacancy is 4.9%, while rents have grown by 15.0%, giving landlords some income momentum without removing leasing risk. Overseas migration is the primary growth driver, which can support tenant demand, although the wider annual trend is only 0.5%. Eleven development applications in the past 12 months indicate ongoing infill activity, mostly involving grouped dwellings. The 16.2% resident turnover rate is lower than a highly transient market, so investors should prioritise well-presented family homes and assess competition from new townhouse supply.

Tenure
Duncraig is strongly detached and family-oriented: separate houses account for 91.9% of dwellings, higher than the 6.3% semi-detached share and far above the 1.8% apartment share. Four or more bedrooms make up 68.8% of homes, while three-bedroom dwellings account for 26.2%, so smaller formats are comparatively limited. Tenure is concentrated among owners, with 41.5% owning outright and 44.6% paying a mortgage, a combined 86.1% that is higher than the 11.9% renting share. Mortgage costs equal 21.3% of household income, higher than the 19.2% rent-to-income measure, while vacancy is 4.9%. Compared with more rental-oriented parts of the northern corridor, this profile should produce steadier occupancy and fewer rapid tenant changes.

The lower full-time rate is consistent with an aging suburb, where more residents are outside the labour force despite strong professional and managerial representation.

Gentrification signals are mixed, with a score of 28 classified as Early signs, while the separate shift measure records a score of 17 and a Not gentrifying stage. Eleven recent development applications suggest gradual infill, but the 0.5% annual rate remains below a high-growth suburban pattern.

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.
