In Australia, many cities have enjoyed a prolonged period of house price increases. As a result, it is safe to say that a large number of Australians have fallen in love with residential investment property as an asset class. The housing price increases that so many investors have enjoyed has also led to a popular perception that residential property is a relatively low risk way to invest.

However, is investing in residential property really that low risk particularly if house prices start declining?

The following information does not take into account your personal objectives, financial situation or needs. You should consider if the relevant investment is appropriate having regard to your own objectives, financial situation and needs.


Let’s compare the risks involved when investing in residential property versus another popular asset class, listed shares. Since the analysis to follow will be focused on risks, it will be looking at what could happen when things go wrong particular when prices decline. It is not meant to be a pessimistic one-sided analysis of investment property versus shares but rather presenting some facts about downside risks which are not often quoted in glossy marketing brochures.

Borrowing Risks

Borrowing money to buy an investment property has become somewhat of a national pastime. While debt on an investment property can significantly increase investment returns when property prices are rising, the opposite is also true. The table below shows how much an investor would lose in principal capital value for a given level of decline in prices and loan to value ratio.

Investment Principal Capital Loss Table

Investment principal and capital loss table

At a 90% loan to value ratio, a house price decline of a mere 5% would result in an investor losing 50% of the equity they have in that investment. Is it possible Australian residential property prices can decline by 5%?

The short answer is yes. In fact, in cities such as Perth and Darwin, the average house prices have already declined by this amount or more over the last 12 months.

Although it is also possible to borrow money for investing in listed shares, the maximum a bank will normally lend against listed shares is much lower than what they will lend against an investment property. For example, many banks will lend up to 90% or more of the value of an investment property but will only lend up to 70% against large blue chip shares. As a result, investors are not able to gear their share investments as much as property investments which leads to a measurably lower risk of suffering substantial losses on principal capital value if prices decline.

Liquidity Risks

During a housing price downturn, it usually takes a longer period to sell a house. Again, let’s take Perth as an example where publicly available statistics show the average number of days for a house to sell has increased from under 50 days when house prices were rising rapidly to over 70 days when house prices started to fall.

If you have an unexpected life event which requires access to cash at short notice, having the majority of your investments in residential property can be an issue. This is an even greater risk if the property has a high loan to value ratio in a declining house price environment as the banks are unlikely to lend any more money against that property.

In comparison, most listed shares (particularly blue chip shares) are highly liquid and can be sold for cash within a few days. Whether it is due to an unplanned need for cash or if you simply want to rapidly de-risk your investment portfolio during a market downturn, listed shares tend to have substantially less liquidity risk than a direct investment in residential investment properties.

Investment Concentration Risk

Do you know someone who owns a residential investment property in the same city or even suburb that they live in?

If that person’s only substantial investment is in one or two residential investment properties, they are likely to have significant investment concentration risk. For example, someone who works in Sydney, lives in in Sydney and invests only in residential property in Sydney is completely exposed to how the Sydney economy performs.

Let’s look at Detroit in the US as an example. The city suffered greatly during the depths of the global financial crisis when the unemployment rate more than doubled and house prices fell by approximately 50%. Undoubtedly there would have been a lot of people in Detroit who lost the regular income from their job and also lost tremendous amounts of money on their Detroit investment properties.

Yes, Detroit is an extreme example and in no way are there any suggestions this could happen in Australia on the same scale but it does show the real danger of potential investment concentration risk.

Even if you decide only to invest in a handful of blue chip listed shares, you are likely to be much better diversified than buying one or two investment properties near where you live. Many large listed companies usually have operations across Australia (or even globally) with multiple revenue streams and provide a much better diversified investment compared to a concentrated investment property portfolio.

For all the reasons above, investing in a diversified portfolio of shares can be less risky than buying 1 or 2 investment properties particularly during periods of price declines.
