Sunbury, VIC 3429

What the market data is signalling

Sunbury shows clear capital-growth momentum: prices are up +8.5% over the last year while rents have lifted a more modest +2.0%. The indicative gross yield of 3.33% (median weekly rent $513) is above the minimum recommended threshold of 3%, so investors can still expect acceptable cash returns — but the primary driver here is price appreciation.

Low Stock on Market (0.34%), tight Inventory (1.98 months) and a fast 29-day median time on market point to competitive buyer conditions. Data confidence: High. For a live view of similar momentum across markets see the Markets in the Moment (MiM™) heatmap.

Who lives in Sunbury — and why it matters for investors

Sunbury records an IRSAD decile of 6, indicating a modestly advantaged socio-economic profile. That mix tends to support steady demand with moderate volatility; it favours long-cycle capital growth rather than highly cyclical price swings. For more on how socio-economic bands link to property performance see the IRSAD Crossover study.

The local tenure mix is neutral — renter/owner at 20% — while the Units/Houses ratio is only 9% (opportune), meaning the market is housing-dominant. Note also affordability sits at 41 years, above the 30-year threshold, which can constrain entry-buyers and support a longer hold strategy.

Why suburb-level data matters for Sunbury

Council-level averages can hide distinctive pockets: Sunbury’s own metrics — a typical house price of $800,481, gross yield of 3.33%, Stock on Market 0.34%, Inventory 1.98 months and median days on market 29 — tell a different story than a generic LGA summary might. Use suburb-level figures to match strategy to real local conditions rather than relying on broad averages. Read more in our LGA vs Suburb research.

What's behind the RCS™ score of 90

HtAG’s RCS™ bundles three independent dimensions — risk minimisation, capital-growth potential and cashflow resilience — into a single composite so you can compare markets quickly. A score of 90 indicates strong overall suitability for investors seeking capital growth with acceptable yield; however, the sub-score breakdown matters when matching to a specific strategy (for example, yield-first versus growth-first approaches).

Forward signals to watch

The vacancy rate — currently 2.36%: at this balanced level rental availability is not exceptionally tight, so expect modest, steady rental growth rather than sharp jumps unless vacancy trends fall below 1%.

The building approvals ratio — currently 2.11%: this elevated approvals reading is unfavourable from a supply-pressure viewpoint; sustained high approvals can add stock and cap some price upside over a 12–36 month horizon.

The wider Melbourne cycle phase: a city-wide shift into a weaker phase would likely temper Sunbury’s local momentum, while expansion across Melbourne would amplify its current growth drivers.
