The missing piece in Australia’s housing debate

Property Investment
The missing piece in Australia’s housing debate

Whether you rent, own your home or have never invested a dollar, private housing investment affects You.

Every rental home exists because someone chose to invest their savings in housing instead of somewhere else.

The biggest mistake in the housing debate is to treat housing as a fixed pie. It is not.

Demand alone does not magically create homes. Supply depends on the capital available to finance it.

Without that capital, demand simply turns into a housing shortage.

If Australia wants more homes, someone has to pay for them, either private investors or the government.

But we are talking about trillions of dollars of housing capital, far beyond what governments can realistically fund given existing debt and deficits.

When private investment leaves housing, it is not investors who suffer most. It is the millions of Australians looking for a place to live.

Housing Market

Housing for millions of Australians

Millions of Australians rent their homes.

For many, renting is not a short stop on the way to home ownership. It is the only practical way to live close to work, education or family.

Without private investors, governments would have to build and manage millions more homes.

No Australian government has ever provided housing on that scale. And if they did the tax burden to every Australian would be enormous.

The private rental market fills that gap similar to any other private businesses providing services we all rely every day. That means all community and renters have a direct interest in private investment.

A healthy rental market gives tenants more choice, more flexibility and more homes to choose from.

Why private housing investment matters

Investment capital is highly mobile.

People with savings can invest in shares, businesses, commercial property, overseas assets, or simply keep their money in the bank.

When investors choose residential property, they are directing private capital toward one of society’s most basic needs: housing.

If housing investment becomes unattractive, that capital does not disappear.

It moves in search of better returns into other sectors of the economy, whether productive or speculative.

The result is less private capital available to finance, build and maintain rental housing.

Over time this increases pressure on government housing systems and leaves tenants and first home buyers competing for a smaller pool of homes.

Private housing investment therefore does more than generate financial returns.

It channels private savings into providing homes that would otherwise require far greater public funding and higher taxes, or in some cases simply would not be built at all.

Housing as a social equaliser

A strong rental market helps people who cannot yet afford to buy a home live in established neighbourhoods alongside owner-occupiers.

It creates more socially mixed communities rather than dividing people by wealth.

Without enough private rental housing, many more households would depend on limited public housing or lower-quality accommodation.

Over time, this can lead to greater social segregation, where access to well-located neighbourhoods increasingly depends on wealth rather than equal opportunity.

A healthy rental market gives students, young families, key workers and people starting their careers the chance to live close to jobs, schools and essential services.

It helps people from different income levels share the same communities instead of separating them.

Private housing investment is therefore about more than providing a roof over heads.

It helps create stronger, more diverse and more inclusive neighbourhoods by making established communities accessible to more Australians.

Why existing property investors matter

There is a belief that only investors who buy newly built homes add to housing supply, while those purchasing existing homes simply push up prices.

That is a flawed view, and when ideology drives policy, it can contribute to a perfect storm of housing shortages, falling living standards, and higher inflation pressures.

Housing finance is not a one-off lump sum magically appearing when a home is built. Housing finance is a decade-long process.

A house is financed throughout its lifetime, with mortgages and ownership passing between several investors over many decades.

Each owner contributes capital, assumes financial risk, pays their share of financing costs and taxes, maintains the property and keeps it available for tenants.

If investment is not supported throughout a property's entire life cycle, it becomes less viable to finance at the very beginning directly reducing supply.

Indeed more tax on existing investors down the line becomes visible in reduced housing commencements shortly.

Investors in newly built housing rely on knowing they can eventually sell the property if their circumstances change.

Banks also rely on a liquid property market when assessing lending risk.

Without a healthy secondary market, lending becomes riskier, more expensive and less available. Many people would never invest in new housing in the first place.

The market for existing homes therefore does not compete with new housing. It makes new housing possible.

How housing investment benefits homeowners

Housing investment benefits everyone who owns a home because owner-occupiers and investors share the same housing market.

A popular claim is that investors simply take homes away from first home buyers. That wrongly assumes the supply homes stays the same whether people invest or not.

It does not. More housing needs more finance.

A steady flow of private investment at each stage of housing life-cycle maintains the existing housing stock and funds new housing, increasing the overall number of homes available to both buyers and renters.

When housing investment becomes less attractive because of higher costs, taxes or regulatory burdens, fewer housing projects are financially viable.

Construction slows, fewer homes are built, and housing shortages become worse.

Ironically, discouraging investment can leave first home buyers facing even fewer homes to choose from.

Existing homeowners are directly influenced by the housing market.

Housing is the largest asset owned by many Australian families. A healthy level of investment supports construction, jobs and confidence in the housing market.

When building activity falls, employment declines, consumer spending weakens and the broader economy slows.

When housing investment collapses, it is not only investors who suffer.

Many families can find themselves in “negative equity” owing more on their mortgage than their home is worth.

Housing investment should therefore not be viewed as benefiting only investors.

It supports the entire housing system by increasing housing supply, creating jobs and helping provide a more stable market for renters, first home buyers and existing homeowners alike.

Benefits beyond housing

Property investment supports far more than landlords and tenants.

Every rental property creates work for builders, plumbers, electricians, property managers, accountants, insurers, banks and many other businesses.

Investors also contribute billions of dollars each year through stamp duty, land tax, council rates, income tax, capital gains tax and GST on construction and maintenance.

Australia's rental market is still dominated by "mum and dad" investors.

Unlike many large institutional investors, they typically spend their money close to home.

They employ local tradespeople, use local property managers, accountants and contractors, and pay taxes that help fund local services.

As a result, much of the economic benefit stays within Australian communities, supporting local businesses and local jobs.

Build-to-rent developments have an important place in Australia's housing market, but they operate under a different model similar to commercial investments.

Unlike the traditional "mum and dad" investor, they are often funded by large institutional investors, including overseas capital.

While they provide housing, more of the financial returns can leave local communities, whereas small Australian investors typically spend, invest and pay taxes close to home.

Tax incentives are not cash handouts

Negative gearing and the capital gains tax discount are often described as government handouts to wealthy investors. They are not.

These rules simply determine how investment income and expenses are taxed. Investors still pay tax. There is no government cheque being written to landlords.

Many rental properties cost more to own than they earn in rent, particularly in their early years.

Negative gearing allows investors to claim those losses against other taxable income, just as many other businesses can deduct their costs.

This encourages people to keep investing in rental housing even when rents do not fully cover the cost of providing it.

Tenants directly benefit because more investors are willing to supply rental homes below their cost.

The capital gains tax discount recognises that investors often accept years of losses or low returns before eventually making a profit when they sell.

It rewards long-term investment, while tenants benefit from the housing provided during those years.

Who really determines house prices?

Another common belief is that high house prices are simply the result of “greedy landlords” overpaying for existing dwellings.

In reality, investors are buyers just like owner-occupiers.

No sensible investor wants to pay more for a property than it is worth.

House prices are influenced by many factors including land supply, planning rules, infrastructure costs, taxes, construction costs, interest rates and government regulation. Investors pay these costs just like everyone else.

Investors do not decide what a house costs. They buy into a market shaped by many forces, most of which are outside their control.

A shared interest

Housing investment is often presented as a battle between landlords and tenants. It is much more than that.

Private housing investment affects everyone.

It provides homes for renters, helps finance new housing for future buyers, supports existing homeowners, creates local jobs, generates tax revenue and strengthens local communities.

Australians believe in a Fair Go.

Housing is more than an investment.

It is the foundation that helps people build a secure future, raise a family and get ahead.

A healthy housing system should create more opportunities, not fewer, by ensuring enough homes for people at every stage of life.

Good housing policy should not divide Australians into landlords and tenants, or investors and non-investors.

Renters, first home buyers, homeowners, workers and governments all depend on the same thing: a healthy flow of investment into housing.

Australia's housing challenges will not be solved by discouraging the people who finance homes. They will be solved by encouraging more investment, more diversity, more opportunities and more housing supply.

Whether you rent, own or invest, we all have a stake in a housing system that delivers enough homes, and a Fair Go, for every Australian.
