7 Regions Revealing the Largest Difference Between House and Unit Growth

7 Aussie Regions Investors Should Know

Australia’s property market is a beast of its own, but within it, a fascinating and growing chasm has emerged between the value of houses and units. While houses have consistently outperformed units for years, recent affordability pressures and changing buyer preferences are starting to reshape the landscape. However, the disparity in growth remains immense in specific regions, presenting both a challenge for aspiring homeowners and a potential opportunity for investors.

At Ash Buyers Agency, in this blog guide, here 7 regions in Australia revealing the largest and most significant differences in growth between houses and units.

1. Parramatta (Sydney)

Oversupply Slows Value Growth While Rentals Hold Steady, but Returns Lag 

Parramatta saw strong growth in unit approvals throughout the 2010s, while approvals for houses remained consistently low.

Units have shown relatively solid rental growth, just 6% less than the growth seen in houses.

2. Strathfield-Burwood-Ashfield (Sydney)

Oversupply Slowed Value Growth, While Rentals Outperformed, but Returns Still Lagged

Over the last ten years, unit building approvals in Strathfield, Burwood, and Ashfield have typically outpaced house approvals, with 2022 being the notable exception.

Apartments in the Strathfield, Burwood, and Ashfield areas have outperformed houses in the rental market, with rents increasing at a slightly faster pace.

3. Ryde-Hunters Hill (Sydney)

Oversupply Slowed Value Growth as Rentals Outperformed but Returns Still Lagged 

Although showing a downward trend, unit building approvals in Ryde-Hunters Hill have remained consistently high over the past decade, significantly outpacing approvals for houses.

Apartments in Ryde–Hunters Hill have shown stronger rental growth than houses, with rents increasing at a quicker rate. This trend is largely driven by the addition of new apartment developments, where higher rental prices have lifted the overall median.

4. South Canberra (ACT)

Oversupply Slowed Value Growth, with Rental Growth Lagging Despite Higher Yields

During the 2010s, South Canberra experienced high and fluctuating unit building approval rates. However, from 2022 onward, these approvals have become much lower and more stable. In contrast, house approval rates have remained consistently low across the entire period.

House rentals in South Canberra have grown n around 30% more than unit rentals over the past decade.

5. Brisbane Inner (Brisbane)

Oversupply Slowed Value Growth, Rentals Outperformed but Returns Still Lagged

Over the past decade, unit approvals in Brisbane’s inner suburbs have been considerably higher than those for houses, which have remained persistently low.

In Brisbane’s inner suburbs, units have outperformed houses in the rental market, recording rental growth around 50% higher over the past decade.

6. Yarra (Melbourne)

7. Melbourne City (Melbourne)

Oversupply Slowed Value Growth, Rentals Outperformed but Returns Lag

Implications for Investors

  • If you’re choosing between a house and a unit in a region with a large or growing gap, you need to decide whether you want capital growth potential (houses often deliver) or cash flow / lower entry cost (units may be easier to buy and manage, especially closer to cities).
  • Also, be mindful of where trends are heading: in some regions, unit growth is catching up (especially where units are well-designed, with amenities, good location), so there may be opportunities in units that many overlook.
  • Always check local specifics: suburb-level data, future infrastructure, demographic trends. That often matters more than the region name.


The gap between house and unit growth in Australia isn’t just a set of statistics; it’s a reflection of changing buyer behaviour, lifestyle priorities, and market dynamics. Sydney’s record-breaking disparities to each region tell a story of how demand for space, affordability, and long-term value plays out differently across the country.


For homeowners, these gaps highlight the affordability challenges of entering the housing market. For investors, they present a choice: pursue the long-term capital growth typically offered by houses, or target units in areas where affordability pressures may drive demand upward in the future.


No matter which path you take, the lesson is clear: understanding regional performance differences is critical to making informed, strategic decisions in today’s property market.
