Catch yourself: Markets change. Human behaviour doesn't.

We've written a lot about the property market this year. In fact, at times we’re asking ourselves what is actually left to say?

We've covered property prices, interest rates, auction clearance rates, economic conditions, buyer confidence, seller expectations, stock levels and just about every forecast from the RBA, the banks and economists about what could, should or might happen next.

But there are parts of a property cycle that receive remarkably little attention, and one of the most important is human behaviour. It doesn’t show up on any spreadsheet, yet sentiment is one of, if not the most valuable things to understand.

In our world, we're hearing all the same conversations that we’ve heard time and time again. We're observing the same behavioural patterns buyers and sellers display in these conditions and, while the circumstances surrounding every property cycle are different, the human response to them is remarkably familiar.

After more than three decades working through different property cycles, we've read this book plenty of times before. The characters change, the economic backdrop changes and the headlines slightly adjust, but the plot has a habit of following a familiar course.

Fear gives way to confidence; confidence can then become excess. Conditions change, denial follows, then acceptance, adjustment and overreaction. Eventually things stabilise and the cycle begins rebuilding again.

As we’ve mentioned many times, there will be no bell ringing when one stage finishes and another begins, which is precisely why understanding behaviour matters. History won't tell us the exact day a market reaches its bottom, but it gives us an extraordinary catalogue of how humans respond when fear, uncertainty and money collide.

And we've seen it all.

Remember the toilet paper madness during COVID? There was never a rational need for Australian households to fill cupboards and garages with months of toilet paper, yet shelves were stripped bare, and people were fighting over rolls because everyone else appeared to be doing the same thing.

More recently, concerns emerged about petrol supply, queues formed at service stations, jerry cans came out and increasingly catastrophic predictions quickly followed.

These aren't stories about unintelligent people, although that could be well argued. They're prime examples of what people do when uncertainty spreads through a crowd. We see people protecting themselves, headlines reinforce the perceived threat, and instinct tells many to do something before it's too late.

So, the key takeaway is that we don't simply respond to risk, we overcorrect.

Property markets are no different.

Think back only six years. When COVID arrived, there were forecasts that substantial property price falls were imminent. Then interest rates collapsed to never-before-seen lows, Australians were told rates were unlikely to rise for years, lockdowns changed how we lived, and attention shifted heavily towards our homes.

Very quickly, the perceived risk changed. It was no longer a fear of paying too much, it became a fear of missing out and the headlines went into overdrive.

Buyers stretched budgets, auctions became fiercely competitive, properties sold immediately and prices rapidly accelerated. People routinely paid hundreds of thousands above expectations because recent price growth was projected forward and waiting suddenly felt more dangerous than buying.

Perfectly intelligent people became caught in collective behaviour. The market wasn't simply rising, human behaviour was amplifying it.

The same thing has happened throughout financial history. Investors chased technology companies during the dot-com boom because extraordinary growth was expected to continue. American housing became a seemingly one-way bet before the Global Financial Crisis. After major share market crashes, investors have repeatedly become most fearful after enormous amounts of value had already disappeared.

Different asset classes, different countries, different decades, yet human behaviour and reactions barely change.

And now the pendulum has swung the other way.

Sydney's correction is no longer something being debated or forecast, it is now well established.

Sellers have adjusted. Transactions are accumulating at lower price outcomes, creating new comparable evidence. Buyers increasingly understand where the new value line sits and, for many properties, that alignment is allowing transactions to occur again.

In fact, correctly positioned quality property is still attracting significant competition. Properties that offer genuine scarcity and strong buyer depth can perform extremely well, even in this environment. While other properties require considerably greater sensitivity around price, presentation and strategy. 

One thing, though, has become brutally clear: anything materially overpriced now stands out and such properties are being ignored by buyers.

We're also seeing something emerge that would have been difficult to comprehend during the COVID boom. There is a significant list of properties purchased in the peak of 2021 and 2022 now reselling for less than their original purchase price. When you also account for the substantial inflation experienced over the same period, the deterioration in real value is seriously significant.

There are also genuine economic reasons for why we are here today. Household finances are under pressure, productivity is pathetic in Australia, borrowing costs remain restrictive, we’ve had a material shift in Government policy from the Federal Budget and another interest-rate increase remains a genuine possibility. If financial conditions tighten again, another step down in property values is entirely possible. 

But buyer psychology has now moved into another stage. For much of this correction, buyers were trying to assess if sellers were lowering prices and by how much before they found some comfort.

They're not asking that anymore. They now know it’s happening.

The question increasingly being considered is how much further prices will fall, and that's where rational caution can begin turning into something else.

Buyers are continuing to price tomorrow’s fear into today’s offers.

When a $5m property became $5.5m during the boom, buyers worried it might soon become $6m. Today, after a significant correction, the same behavioural mechanism works in reverse. Whatever a property is worth today, there is an assumption it will be worth less tomorrow.

During the boom, people extrapolated rising prices.

Today, they're extrapolating falling prices.

During the boom, fear said buy before you miss out.

Today, fear says wait because it will be cheaper later.

Same human being, same protective instinct, but in the opposite direction.

Importantly, buyers can be directionally right and still overcorrect. Property values may fall further, but that doesn't mean every property needs another arbitrary 10 or 20 per cent margin built into its value today. At that point, the buyer is no longer simply pricing the property on the available evidence, they're attempting to insure themselves against an unknown future.

That is where caution morphs straight into fear, and we've seen this before.

So where are we in the cycle?

Sydney has now well and truly moved through the denial phase.

The repricing is well underway.

The majority of sellers have adjusted, new comparable evidence is accumulating, and buyers are more accepting of a different value line. Transactions are occurring around those new levels and competition is returning selectively where the property, price and buyer depth align.

The next behavioural stage is already appearing, and that is overcorrection.

That doesn't mean we’re declaring the bottom of the market is in. With a further rate increase or deterioration in economic conditions, we can absolutely see another repricing event occur. But every correction eventually reaches a stage where people move beyond pricing known risk and begin pricing increasingly extreme versions of what might happen next.

That's the behaviour worth watching now.

Not another economist's prediction.

Not another headline forecasting where Sydney property prices might be in 12 months.

Watch people.

Watch what happens when another piece of bad news lands. Watch whether correctly priced properties continue to transact. Watch whether quality homes continue attracting multiple buyers. Watch whether buyers who have spent six or twelve months waiting begin competing again. Watch whether bad news continues producing the same negative reaction it did six months earlier.

Because eventually something changes. The news can remain bad while human behaviour starts improving. That's when you know the cycle is about to turn.

We've seen people hoard toilet paper they didn't need. We've watched people queue for petrol because they feared there wouldn't be any tomorrow. We watched buyers chase property during COVID because they believed prices might keep running away from them.

At the time, people reasoned with the evidence and had an explanation to convince themselves to behave in that way. In hindsight, the pattern is obvious. The challenge is recognising it while you're standing inside it.

Markets change. Human behaviour doesn't.

So perhaps the most valuable question this spring isn't where property prices will be in six or twelve months. Nobody knows that with certainty.

Maybe you’re better asking: are you making decisions from ego or fear and becoming part of a pattern, we've seen play out for generations, or are you reading the conditions clearly, weighing the evidence and making a measured decision based on what is actually happening?
