The median house price reached $1,080,000 in Q1 2026, up 23.6% from $873,500 a year earlier in Q1 2025. That is strong appreciation for a suburb where separate houses account for 90.3% of stock, meaning most transactions are for standalone properties on real land. Three-bedroom homes are the dominant dwelling type at 57.5%, and 4-plus bedroom homes make up 33.7%, so buyers get genuine family-sized properties rather than compact stock. Monthly mortgage repayments average $1,733, producing a mortgage-to-income ratio of 23.1%, which sits below the 30% stress threshold. Ownership rates are high, with 43.6% owning outright and 39.5% on a mortgage, meaning only 16.9% of residents rent, lower than most Adelaide suburbs.

For Investors
The low renter share of 16.9% against weekly rent of $380 signals that Dernancourt is not primarily a rental suburb, and investors need to factor that into yield expectations against the $1,080,000 median. The 3.7% vacancy rate is moderate and not concerning. Development activity is active with 60 applications in the past 12 months, including land divisions and new dwellings, suggesting the suburb has room to gradually intensify. Population growth is driven mainly by overseas migration at a net average of 98 people per year, compared to net internal migration of only 16, providing a steady tenant pipeline. Rent grew 25.0% over the past period, well above inflation, which supports the investment case despite the thin renter base.

Tenure
Tenure in Dernancourt is heavily weighted toward ownership: 43.6% own outright and 39.5% carry a mortgage, leaving only 16.9% renting. Outright owners outnumbering mortgage holders at 43.6% vs 39.5% is unusual and indicates long-term, established residents with fully paid-off homes. Separate houses make up 90.3% of the housing stock, one of the most detached-dominant profiles in the region. The median house price rose from $873,500 to $1,080,000 in a single year, a 23.6% gain. Three-bedroom dwellings dominate at 57.5% and 4-plus bedroom homes at 33.7%, so the supply is family-oriented. Rent-to-income at 21.9% and mortgage-to-income at 23.1% are both below typical stress levels, reflecting solid household finances relative to housing costs.

Population Forecast
+0.6%/yr
(+71 people/yr)
EstablishedDernancourt's population grew 6.6% over 10 years, modest by metropolitan standards, and the current annual growth rate is 0.6% or approximately 71 persons per year. The primary driver is overseas migration at a net average of 98 per year, with internal migration adding only 16 net annually. Medium forecasts project the SA2 population reaching approximately 11,991 by 2031 from a current 11,781, implying continued steady growth rather than rapid expansion. The gentrification score is 18, classified as not gentrifying, which fits a suburb already at IRSD decile 9. Affordability improved from 47.0% in 2011 to 44.9% in 2021, a modest improvement. The aging trajectory means demand will shift gradually toward lower-maintenance dwellings over the next decade.

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 Valuer-General (house prices), Department of Jobs SALM (unemployment), ACARA (school ICSEA), state Crime Statistics agencies (offences), council DA portals (development applications). Population forecasts use a Hamilton-Perry cohort model calibrated to ABS ERP.
