Adelaide Suburbs Under $700k: Where to Buy Right Now

Quick Answer

Adelaide still has suburbs where you can buy a house under $700,000 -- but you need to look beyond the inner ring. The northern corridor, southern suburbs, and parts of the eastern foothills offer genuine value, with medians well under this threshold. Act with solid research because prices in these areas have been moving upward.

Adelaide's Affordable Suburbs in 2025

Adelaide has long been regarded as the most affordable of Australia's major capitals, and while that gap has narrowed, the city still delivers options that Sydney and Melbourne buyers can only dream about. Suburbs within 20-35 kilometres of the CBD can still be purchased below $700,000.

The key is understanding which corridors still offer real affordability. Adelaide's price growth has been uneven -- inner and coastal suburbs have surged, while the northern corridor and outer south have seen more moderate increases.

Northern Corridor

The northern suburbs from Salisbury through to Elizabeth offer some of the most affordable housing in any Australian capital. These areas benefit from significant infrastructure investment, including the Torrens to Torrens motorway upgrades and the Gawler rail line electrification.

Salisbury sits around 20 kilometres north of the CBD with a median house price near $580,000. It has schools, shops, and direct rail access to the city. Salisbury East and Salisbury North offer similar value.

Parafield Gardens has a median around $590,000. It is a well-established suburb with parks, good primary schools, and easy access to the northern expressway for those who commute by car.

Mawson Lakes is a master-planned suburb about 16 kilometres from the CBD with a median around $660,000. It has the University of South Australia campus, a town centre, and its own train station. The infrastructure here is strong for the price.

Elizabeth Grove and Davoren Park are the most affordable options in the corridor, with medians under $500,000. These are working-class suburbs with solid rental demand, making them popular with investors.

Southern Suburbs

The southern Adelaide suburbs offer a different lifestyle proposition -- coastal access, established character, and proximity to the Fleurieu Peninsula.

Morphett Vale sits around 25 kilometres south of the CBD with a median near $640,000. It has a large shopping centre, schools, and a mix of older homes and newer infill development. The suburb has seen solid price growth as buyers are priced out of suburbs closer to the city.

Christie's Beach is a coastal southern suburb with a median around $620,000. It sits on Gulf St Vincent with a relaxed beach lifestyle that would cost double in northern beachside markets.

Reynella and Old Reynella are established southern suburbs with medians around $630,000. Old Reynella in particular has heritage streetscapes and a village feel that punches above its price point.

Seaford and Seaford Meadows are newer southern coastal suburbs with medians around $620,000-$650,000. Modern housing stock, walking distance to the beach, and access to the Noarlunga train line make these appealing for families.

Eastern Foothills Fringe

Modbury and Modbury North sit in the north-eastern suburbs about 16 kilometres from the CBD. Medians hover around $640,000-$660,000. The Tea Tree Plaza shopping precinct is close by and the area has strong community infrastructure.

Golden Grove is a planned community in the north-east with good schools and open space. The median sits around $680,000 -- towards the top of this budget but offering larger blocks and modern streetscapes.

Tea Tree Gully is a gateway to the Adelaide Hills with a median around $650,000. It has significant green space, a strong community, and a cooler microclimate in summer.

Example

Sophie and Marcus are a couple in their early 30s with a combined income of $180,000 and a deposit of $120,000. Pre-approved for $640,000, they looked at suburbs within 25 kilometres of the CBD.

They started in Mawson Lakes, drawn by the university precinct and train station. After viewing several properties, they found a three-bedroom home on a 400-square-metre block listed at $655,000. The sellers accepted $641,000. Sophie works in healthcare in the northern suburbs and Marcus commutes into the city by train -- the location suited both.

They are now in their second year of ownership and the suburb's median has moved to approximately $675,000.

Checklist: Buying Under $700k in Adelaide

• Set a firm budget ceiling that includes stamp duty (~$26,000 on a $650k purchase for owner-occupiers), conveyancing, and building inspection costs
• Research each suburb's median price trend over 12 months to understand whether values are rising quickly
• Check proximity to the train or tram network -- transport access strongly influences future resale value
• Inspect the property for asbestos in homes built before 1985, common in the northern and southern corridors
• Verify flood and bushfire overlays on the SA Planning Portal for any eastern foothills property
• Request a building and pest inspection before making a formal offer
• Confirm school zones if schooling is a factor -- zone boundaries matter in suburbs with sought-after schools
• Compare similar recent sales in the suburb rather than relying on agent price guides
