Homebuyers in Success are mainly competing for larger detached homes, with 79.9% separate houses and 60.1% of dwellings having 4 or more bedrooms. The median house price is not available, so affordability is better read through repayments: the median mortgage is $1,950 a month and mortgage costs equal 20.9% of income. That is below a stress setting, because household income is high at $2,155 a week and sits in the 82nd percentile nationally.

For Investors
Success has a usable rental base rather than a pure investor market: 30.1% of homes are rented, compared with 53.4% under mortgage. Median rent is $400 a week and rent absorbs 18.6% of income, which supports tenant affordability. The caution is vacancy at 6.4%, higher than a tight rental setting, so pricing discipline matters. Demand is helped by forecast overseas migration of 378 people a year and net internal migration of 255 a year, while only 2 approvals in 12 months limit new local supply.

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.
