What does this mean for me?

CoreLogic’s director of advisory and risk management, Dr Pierre Wiart, said coastal risks will crystallize over the next three decades, describing recent extreme weather events as “tangible effects of climate change”.

“This has direct physical and financial consequences. Coastal risk has far-reaching implications for the country’s property market and its supporting financial sector, including property valuations, home lending viability and insurance premiums.

CoreLogic Research Director Tim Lawless added that the shift to remote working has led to a significant acceleration in coastal property values ​​over the past two years, with Queensland’s Gold Coast and Sunshine Coast seeing year-on-year increases. median value of 33.0% and 34.4% respectively in the 12 months to January 2022.

According to Dr. Wiart, it is important that owners, potential buyers and the real estate and financial sectors understand the risks associated with coastal properties, which could include:

Lower home values ​​and riskier home loans

If you own or plan to buy property in a coastal area, it is possible that your property value will increase more slowly or even decrease over time due to the higher risk of being affected by coastal erosion, l sea ​​level rise or higher. It may also be more difficult to successfully apply for and/or refinance a home loan if lenders are concerned about the risk for these properties.

According to Dr. Wiart, “credit risk and long-term lending are directly impacted by these natural tendencies. Similarly, for any financial institution, it is important to assess the potential decline in real estate values ​​or the concentration of a portfolio at risk.

Less insurance coverage and higher premiums

It’s no secret that insurance costs more in some parts of Australia than others, with premiums quickly becoming unaffordable in areas most prone to natural disasters such as flooding.

According to Dr. Wiart, “the increase in coastal risk also increases the pressure on insurance. Homeowners face rising insurance premiums and limited insurance coverage, reducing the affordability of their insurance and the protection of their important assets.

What steps can I take?

Before applying for a mortgage to buy or refinance a coastal property, you might consider ordering a free property report to get an idea of ​​its approximate value and other important information.

Comparing home loans can help you find a suitable mortgage offer for your financial situation, but you can contact the lender to find out if they have any special conditions for risky properties on the coast or elsewhere. A mortgage broker may also be able to help you find a home loan and mortgage lender that suits your needs.
