The gap that keeps growing: houses and units are moving in opposite directions in Dandenong

The numbers are stark. Median house prices in Dandenong have climbed to approximately $685,000 as of the June 2026 quarter, while the median unit price has drifted to around $420,000, a gap of more than $260,000 that has widened by roughly 18 percent over the past 18 months. For buyers, renters and investors watching the suburb's fast-moving market, that divergence is no longer a footnote. It is the story.

The split matters right now because Dandenong is entering a period of concentrated supply change. The Dandenong Priority Precinct, designated under the Victorian Government's Plan Melbourne framework, has been pushing higher-density approvals through council for three years. Many of those approved projects, concentrated along Lonsdale Street and near the Dandenong train station precinct, are reaching settlement simultaneously, flooding the local unit market with new stock at a moment when detached house listings remain historically tight.

Why houses keep climbing while units stall

Demand for freestanding homes on Dandenong's residential streets, particularly around the Walker Street and Cleeland Street corridors, has not eased. Owner-occupiers competing with investors have kept auction clearance rates for three-bedroom houses above 72 percent through the first half of 2026. That competition has no equivalent in the unit segment, where a glut of one-bedroom apartments near the Central Square shopping precinct has given buyers real negotiating power for the first time since 2021.

The Greater Dandenong City Council's own housing strategy, adopted in late 2024, flagged this as a known risk. The strategy projected that between 1,400 and 1,800 new dwellings would be approved across the precinct by mid-2026, with the majority being medium and high-density product. Those projections appear to have been accurate. Real estate agencies operating out of the Dandenong central business district have reported average days-on-market for units sitting at 48 days in June 2026, compared with just 19 days for comparable houses.

First-home buyers are caught in the middle. The Victorian Homebuyer Fund, which allows eligible buyers to purchase with as little as a five percent deposit, has a price cap of $700,000 for established dwellings, a figure that puts most Dandenong houses within reach on paper, but leaves little margin when competition pushes final prices above reserve. Units, by contrast, are increasingly sitting below $500,000, making them eligible and theoretically accessible, but the resale uncertainty in an oversupplied segment is a genuine concern for buyers advised by local buyer's advocates.

What the divergence means for investors and renters

Investors watching yields tell a different story depending on which side of the divide they sit. Gross rental yields on Dandenong units have compressed to around 4.1 percent as asking rents have not kept pace with prices from two years ago. Houses, meanwhile, are returning gross yields of approximately 3.6 percent, lower in dollar terms, but backed by stronger capital growth expectations and land scarcity that no new apartment tower can replicate.

For renters, the oversupplied unit market has produced one concrete benefit: vacancy rates in the Thomas Street and Robinson Street apartment precincts have ticked up to 4.2 percent, the highest since 2019, giving tenants room to negotiate on price or conditions in a way that was unimaginable eighteen months ago.

The practical read for anyone making a decision in Dandenong's market before the end of 2026 is this: houses near the Dandenong North primary school zones and the Tirhatuan Park corridor are unlikely to soften, and buyers waiting for a correction may be disappointed. Units require sharper due diligence, especially off-the-plan stock where settlement risk and body corporate fees can erode the apparent affordability advantage. The gap between these two markets is a structural feature now, not a temporary blip, and anyone treating them as interchangeable assets is working from an outdated map.
