Frequently asked questions
Is SA a good place to buy an investment property in 2026?
Yes, SA continues to deliver above-average long-term capital growth, with the strongest fundamentals around Adelaide and well-connected regional centres. Buy-and-hold investors benefit from tight vacancy rates, infrastructure spend, and steady migration. Always model holding costs against your serviceability before committing.
What gross rental yield should I expect in SA?
Gross yields in SA typically sit between 3.5% and 6.5% depending on suburb, dwelling type and price point. Houses in middle-ring suburbs trend toward the lower end, while units in growth corridors and regional centres can sit comfortably above 5%.

Should I buy a house or an apartment in SA?
Houses generally deliver stronger long-term capital growth in SA thanks to land value. Apartments and townhouses can deliver better cashflow and lower entry prices, particularly within 10 km of Adelaide. The right answer depends on your strategy (growth, yield, or balanced), holding period and tax position.
What suburbs in SA have the strongest growth outlook?
Suburbs benefiting from new transport infrastructure, school catchments, employment hubs and gentrification typically outperform. See the "Top 10 Investment Suburbs in SA" table on this page for Shelby's current shortlist, refreshed using ABS, CoreLogic, Domain and SQM data.
