What Really Drives Housing Affordability? Economic, Investor, and Policy Insights
Pina Brandi • October 30, 2024

In our previous post, we examined the structural barriers to Australia’s housing affordability. Here, we’ll delve deeper into the economic forces at play, how investor behavior affects affordability, and the potential for policy changes to create a balanced, accessible property market.


Economic Realities Shaping the Housing Market

Three primary economic factors contribute to the current affordability crisis:

  1. Income vs. Property Prices
    One of the biggest challenges is the widening gap between wages and property prices. While incomes have stagnated, property values have surged. Without either significant wage growth or a substantial drop in home prices, affordability will remain out of reach for many Australians.
  2. Interest Rates and Borrowing Costs
    Despite several recent rate hikes, housing demand has remained strong. As rates potentially decline in coming years, borrowing costs will fall, further increasing competition for property and driving prices up once again.
  3. Investor Activity in the Property Market
    Investors, especially “mum-and-dad” investors who own approximately one-third of Australia’s rental properties, play a significant role in shaping property demand. While often accused of pushing out first-home buyers, investors are also crucial in providing rental housing and supporting new development. Limiting investor activity could alleviate short-term demand but might also reduce rental availability, inflating rental prices.


Foreign Investment and Its Impact on Affordability

Foreign investors have long been a part of Australia’s housing market, particularly in urban and luxury segments. While their role is debated, foreign investments often help fund developments that increase housing supply. Striking a balance is essential to ensure they support the market without exacerbating affordability issues.


Social and Political Factors

  1. Homeowner Influence
    Approximately 70% of Australians either own their home outright or are paying off a mortgage. This group has a vested interest in preserving or growing property values, and policy changes that could threaten these values face strong opposition. Homeownership creates a "wealth effect" that encourages spending, driving economic growth.
  2. The Paradox of Affordability
    The paradox for first-home buyers is that they want affordable housing until they become homeowners. At that point, they, too, often desire property appreciation. This shift reflects a broader societal tension: while the goal of affordability is universally supported, there’s little appetite for policies that might lead to lower property values.


Policy Recommendations for a Balanced Market


For lasting improvements in housing affordability, coordinated policy and social efforts are necessary. Here are a few key approaches:

  • Comprehensive Urban Planning
    Planning should involve all levels of government and private partnerships to develop homes in strategic locations, supported by essential infrastructure.
  • Zoning Flexibility
    Relaxing zoning laws could promote higher-density development in desirable areas, increasing the housing supply without sprawling into distant suburbs.
  • Government Investment in Affordable Housing
    Public investment in affordable housing options could alleviate pressure on the private market, helping lower-income Australians secure homes without relying on market-rate options.
  • Addressing Development Costs
    Streamlining regulatory processes and reducing development costs can lower new housing prices, making outer suburb developments more accessible.



Australia’s housing market is shaped by various interwoven economic, social, and political factors. With balanced policies and coordinated efforts, affordable housing may be achievable, but it will require time, innovation, and collaboration at all levels.


Tackling this challenge could pave the way for future generations to achieve the dream of homeownership.

Around 2017–2018, growth stalls and dips modestly after APRA’s investor growth cap (2014) and interest‑only cap (2017), which is the effect you’re asking about.

Melrose Park’s transformation from an industrial precinct into a residential and mixed-use community has been a strategically significant shift for Sydney’s urban future. Historically, the area was home to pharmaceutical and light-industrial operations, but over time these industries declined, consolidated elsewhere, or simply outgrew the outdated warehouses and fragmented road layout. Keeping the land zoned industrial would have meant under-utilising a large, strategically located pocket of Sydney at a time when housing demand is at critical levels. Redeveloping Melrose Park allows Sydney to introduce thousands of new homes in an inner-suburban area without pushing growth further to the city’s outskirts. With capacity for around 10,000–11,000 dwellings, plus retail, open space, a new high school and community facilities, the precinct is envisioned as a self-contained, modern neighbourhood with liveability at its core. Instead of being an isolated residential pocket, Melrose Park is being planned as a walkable, amenity-rich town centre where green spaces, urban parks, and mixed-use buildings form a cohesive and sustainable environment. Its location is one of its strongest advantages. Positioned on the Parramatta River, the suburb sits almost exactly halfway between Sydney CBD and Parramatta CBD, making it highly attractive for commuters who want balance, convenience and lifestyle. It is minutes from major employment hubs, established transport corridors like Victoria Road, and future connections that will further integrate the precinct into Sydney’s broader network. The land parcel is also unusually large and contiguous for an inner-suburban area, enabling a full masterplan rather than piecemeal development.  Overall, the shift from industrial to residential in Melrose Park wasn’t just a rezoning exercise; it was a strategic realignment of land use to meet Sydney’s changing economic, demographic, and lifestyle needs. Its prime location ensures the precinct will continue to attract demand, support growth, and deliver long-term value for residents and investors alike.
