How to Check a Property’s Flood, Bushfire and Insurance Risk Before You Buy

Flooding is not just a problem for houses sitting right next to a river.

Heavy rain can cause flash flooding. Stormwater systems can become overwhelmed. Low-lying roads can flood and water can move across properties that look completely normal when you inspect them on a dry day.

I would first check whether the property is in a mapped flood area.

Each state has different mapping systems and terminology, so you need to look at the relevant government or council information for the actual address.

Do not rely on the agent saying that it has never flooded, it could be true. But it still does not tell you what the official mapping says or what could happen in a major weather event.

Look at the property, not just the suburb

A suburb can have a flood risk without every property in it having the same level of exposure.

One street can sit higher than another. One side of a road can be affected while the other is not.

The position of the house on the block matters too.

Look at the slope of the land, where water would naturally run, the position of drains and whether the house sits higher or lower than the road.

If you are buying an existing house, look for signs of previous water damage as well.

Staining, damaged flooring, mould, repaired walls or recently replaced lower sections of the house are things I would want explained.

A building inspection can help, but it does not replace checking the property’s flood history and official mapping.

Then check the bushfire risk

Bushfire risk is another one that can be easy to overlook when a property looks perfectly normal.

You do not have to be surrounded by dense bush for the risk to matter.

Grassland, forests, parks and large areas of vegetation can all be relevant depending on the location and conditions.

Again, I would check the actual property rather than making assumptions based on the suburb.

Each state has its own bushfire mapping and planning controls. Some properties can also have specific building or planning requirements because of their location.

If the property is near bushland, I would want to know what the official mapping says, what access is available and whether there are any restrictions or requirements attached to the property.

A pretty house backing onto bush might look great during an inspection. The same position can carry a very different level of risk during a major fire.

Insurance can tell you a lot

This is one of the checks I would do before getting too far into the buying process.

Get an insurance quote for the actual property. Not a rough estimate for the suburb. The actual address.

The insurer will assess the property based on its location and other risk factors. The result can tell you very quickly whether there are issues you need to investigate further.

You might find that the premium is much higher than expected.

You might find that certain conditions or exclusions apply.

Or you might have difficulty finding a policy that provides the level of cover you need.

That matters because insurance is an ongoing cost of owning the property.

A property that looks cheap to buy can become a very different investment once you add a large insurance bill to the annual holding costs.

Do not just look at the premium

The cheapest insurance policy is not automatically the right one. You need to understand what is actually covered.

Check the level of building cover, excesses and any exclusions or special conditions that apply.

For properties in areas exposed to flood or bushfire, I would pay particular attention to how those risks are treated under the policy.

The exact cover depends on the insurer and the policy, so this is something to confirm directly rather than assuming every policy works the same way.

If the insurance quote comes back much higher than expected, I would want to know why before buying.

Look at what has happened before

Past events can tell you something that a property listing cannot.

Search for flood history, previous bushfires and other major events affecting the area.

Talk to neighbours if you can.

Ask the selling agent direct questions about the property’s history.

If there has been previous damage, find out what happened, what was repaired and whether there are records of the work.

For flood affected properties, I would want to know whether water entered the house itself or whether flooding was limited to the street, yard or surrounding area.

For bushfire affected areas, I would want to know whether the property or nearby properties have previously been damaged.

You are trying to build a picture of what has actually happened at the property, not just what the agent says might happen.

The risk can affect more than the house

These risks can have an effect on the value and appeal of the property as well.

Some buyers will not want to live in a flood affected area.

Others will not want a property close to bushland because of bushfire exposure.

That reduces the pool of people who might want to buy the property from you later.

It can also affect rental demand.

A tenant looking for a home may have concerns about flooding, access during heavy rain or bushfire exposure, especially if they have other properties to choose from.

You need to understand what you are buying and who will want it in the future.

The cheapest house is not always the cheapest property

Say two similar houses are available for $550,000.

One has normal insurance costs and no major known environmental risk.

The other is in a flood affected area and costs several thousand dollars more each year to insure.

The purchase price might look similar, but the ongoing cost of owning them is not.

And that is before you consider potential repairs, higher excesses, difficulty getting cover or the effect the risk could have on future buyers.

I would rather know all of those costs before deciding what a property is worth.

What I would check before buying

Before I bought a property, I would want to know:

• Is the property in an official flood affected area?
• Has the property flooded before?
• What does the local flood mapping show?
• Is the property exposed to bushfire risk?
• Are there any bushfire planning or building requirements?
• What does the actual insurance quote look like?
• Are there any exclusions or unusually high excesses?
• Has the property had previous flood, fire or storm damage?
• What repairs have been carried out?
• Does the risk affect rental demand?
• Would future buyers have the same concerns?
• Does the property still make sense once all of these costs are included?

I would also have the usual building and pest inspections completed and speak with the relevant professionals where the property has a known risk.

The point is to find these things out before you commit, not after you own the property.

What I would focus on

I would not rule out every property with some level of flood or bushfire exposure.

There are plenty of properties across Australia where environmental risk forms part of the location and the property can still be owned successfully. But I would want the risk to be understood and reflected in the price.

If two properties are similar in every other way, I would want to know why one has a much higher insurance cost or a smaller pool of future buyers.

I would also be careful about buying a property because it looks cheap without finding out why it is cheaper.

Final word

Flood and bushfire risk are things you should check before buying, not after settlement.

Look at the official mapping, investigate the property’s history and get an insurance quote for the actual address.

Then work those costs and risks into the decision.

A property is more than the house you can see during the inspection. Where it sits, what has happened there before and how easy it is to insure all form part of what you are actually buying.
