The Biggest Risks Property Investors Tend to Ignore

The possibility that property prices may fall is often the biggest risk for property investors. But the truth is that the greatest risks are the less obvious ones.

Here are some property investment hazards to consider before you take the plunge, or before you expand your existing property portfolio.

Today’s tax rules are not guaranteed to be tomorrow’s rules

Property investors may be making decisions that cover long time horizons, possibly stretching into decades. But the regulatory and tax environment may undergo significant changes in the years following a property purchase.

Two prime examples of this are the proposed changes to CGT and negative gearing, planned to come into effect from 1st July 2027. Property investors are likely to need to consult their financial adviser to discuss the effects on their property portfolio of the scrapping of the potential 50% CGT discount in favour of an inflation-based indexation system for taxing capital gains, and the limiting of negative gearing to newly-built residential properties if purchased after 12th May 2026.

However, these are only illustrations of the types of rule changes that can occur during the life of a property investment. A good rule for investors is to not buy a property simply because the tax treatment today makes the numbers work. Buy it instead because the underlying investment makes sense, with the tax benefits treated as an advantage rather than the foundation of the strategy.

Interest rates can change quickly

Rather than focusing on whether you can afford a loan at current interest rates, as an investor you should ask yourself whether you could comfortably cope if your repayments became substantially higher.

The Australian Prudential Regulation Authority (APRA) has already identified high debt-to-income lending to investors as an area of increasing risk. Since February 2026, banks have been subject to limits on new lending where debt is six or more times income.

Remember, too, that interest-only loans do not reduce the loan principal, and that if you have an interest-only introductory period, the higher repayments when it expires can be a significant cash flow shock.

The rent may not always cover the mortgage

Rental income is not guaranteed. A good property investment strategy should survive a bad rental year, not just an average one. You may experience failures to pay rent when due, vacancies between tenants, tenant damage, unexpected repairs and even falling rents.

Capital growth prospects should not eclipse cash flow considerations

Many investors accept a negative cash flow because they expect capital growth to compensate for it. This can work, but it makes you vulnerable. If a property costs you $200 a week more than it generates in income, you are into negative territory by more than $10,000 per year, before any unexpected expenses. You could become very dependent on your employment income to sustain your property portfolio.

Don’t forget to diversify

If your property portfolio is doing well, it can be tempting to concentrate too much of your wealth in property to the exclusion of other assets. As well as diversifying your property portfolio itself by spreading the risk amongst different property types in separate areas, invest in other asset categories as well, so that you are not exposed to the same broad asset class, property cycle and taxation rules.

Also keep enough of your capital in cash to give you the capacity to deal with an extended vacancy, major repairs, higher interest rates or an unexpected loss of employment income. Property is a non- liquid asset. If you suddenly need cash, it can take time to sell a property, and you may have to sell during a market downturn.

Look before you leap

Owning an investment property can be an important part of your wealth strategy, but consult your financial adviser for guidance to ensure you are prepared for when rental income falls, interest rates rise, property values stagnate, or your personal circumstances change.
