Markets do not usually break without warning.
They send signals first.
In commercial real estate, those signals are often subtle. They show up in conversations, in deal structures, in small changes to assumptions. Most people ignore them because things still look strong on the surface.
By the time the shift becomes obvious, pricing has already adjusted.
Over time, I have learned that market overconfidence follows patterns. It does not happen randomly. It builds slowly, then shows up all at once.
When Assumptions Start Stretching
One of the first signs of overconfidence is when assumptions begin to stretch beyond what the market has historically supported.
Rent growth projections start to feel aggressive. Vacancy assumptions become overly optimistic. Exit cap rates assume perfect conditions.
On paper, the deal still works.
That is the problem.
I remember reviewing a deal where projected rent growth was doing most of the heavy lifting. The current income was stable, but the value depended on rents increasing well above recent market trends.
I asked a simple question.
“What happens if rent growth slows down?”
The room went quiet for a moment. The model had not been tested under that scenario.
When assumptions stop being questioned, overconfidence starts to build.
Pricing Disconnects from Fundamentals
Another signal is when pricing moves faster than underlying performance.
Property values should be tied to income, risk, and market conditions. When prices rise significantly without a clear change in those fundamentals, something else is driving the market.
Often, that “something else” is capital.
When financing is easy and capital is abundant, buyers compete aggressively. They accept lower returns. They justify higher prices with optimistic assumptions.
I have seen buildings trade at values that did not reflect their current income or risk profile. At the time, those deals were supported by strong market sentiment.
Later, when conditions shifted, pricing adjusted quickly.
Lease Quality Gets Overlooked
In strong markets, people focus on occupancy and rent levels.
In overconfident markets, they stop paying attention to lease quality.
Short-term leases, tenant concentration, and early termination clauses begin to receive less scrutiny. As long as the building is full, the details feel less important.
That is a mistake.
I once worked on a property that was fully occupied with strong rents. It looked like a high-performing asset.
Then we reviewed the lease schedule.
A large portion of the space was set to expire within two years. Several tenants had flexible exit options.
“Everyone is focused on today’s occupancy,” I said during the review. “But from an operator’s perspective, this income is not as stable as it looks.”
Overconfidence often hides in the details people choose to ignore.
Speed Replaces Discipline
When markets heat up, deal velocity increases.
Transactions move quickly. Due diligence periods shorten. Negotiations become less detailed.
Speed can feel like progress, but it often replaces discipline.
I have seen situations where investors skipped deeper analysis because they were worried about losing a deal. The focus shifted from understanding risk to winning the transaction.
That mindset rarely ends well.
When decisions are made too quickly, important questions go unasked.
Everyone Starts Agreeing
Another signal is consensus.
When most people in the market share the same view, it often means the cycle is nearing a turning point.
You start to hear similar language across conversations. “This time is different.” “Demand will stay strong.” “There is too much capital for prices to fall.”
Those statements are usually based on recent trends, not long-term perspective.
Markets move in cycles. Conditions change.
When everyone agrees on the direction of the market, it is worth asking what might challenge that view.
Financing Becomes Too Easy
Access to capital plays a major role in market behavior.
When lenders are willing to offer favorable terms, higher leverage, or reduced scrutiny, it can fuel overconfidence.
Borrowers take on more risk because financing allows it. Investors accept thinner margins because debt is inexpensive.
This dynamic pushes pricing higher.
I have seen deals where the financing structure made the transaction possible, not the underlying fundamentals.
When capital conditions tighten, those deals become harder to support.
Early Warning Signs from the Ground
Some of the most reliable signals come from people working directly in the market.
Leasing agents notice when tenant demand starts to slow. Property managers see changes in tenant behavior. Lenders adjust underwriting before it becomes obvious.
I remember speaking with a leasing broker who said, “We’re still closing deals, but every tenant is pushing harder on concessions.”
That was an early sign.
The market had not corrected yet, but the tone was shifting.
These conversations often reveal changes before they appear in formal data.
How to Stay Grounded
Spotting overconfidence is not about predicting exact timing. It is about recognizing when risk is increasing.
There are practical ways to stay disciplined:
- Test assumptions under multiple scenarios
- Focus on lease structure, not just occupancy
- Compare pricing to historical trends
- Pay attention to financing conditions
- Listen to people working in the market
These steps help maintain perspective.
Why It Matters
Overconfidence does not mean a market is about to collapse.
It means expectations may be out of balance with reality.
When that happens, small changes can have larger effects.
Interest rates rise. Tenant demand shifts. Financing becomes more selective.
The market adjusts.
Those who recognize the signals early are better positioned to respond. They make more measured decisions. They avoid relying on assumptions that may not hold.
In commercial real estate, discipline tends to outperform optimism over time.
The signals are usually there.
You just have to pay attention to them.
