There is a phrase that gets used more than any other in commercial property when a landlord asks why their unit is still empty. You will have heard it. You may have said it yourself.
It's just the market.
It is the most convenient explanation in the industry, and the least honest. Because here is the reality. In every market, in every economic climate, properties still let and sell. Sometimes quickly, sometimes slowly. Sometimes for strong money, sometimes for less than the landlord hoped. But they move.
The question worth asking is not what the market is doing. It is why some properties get taken whilst others sit empty for months and years, gathering blight and quietly losing value.
The market is not a single thing that affects all properties equally. It is a collection of individual decisions made by individual occupiers and investors, each of whom is looking for something specific. When a property sits empty whilst others around it are being taken, the market is telling you something. Most landlords and their agents aren't listening.
There is always a reason why a property isn't being absorbed. Always. Sometimes it is price. Sometimes it is condition or presentation. Sometimes it is a mismatch between what the landlord is offering and what occupiers in that area actually need. Sometimes it is simply that nobody knows the property exists, or the way it has been presented makes it look like more trouble than it is worth. The job of a good agent is to find that reason, say it plainly, and fix it. The job of a good landlord is to listen.
What tends to happen instead is this. The property sits on the market for a few months with no serious interest. The agent, not wanting an awkward conversation about price or presentation or their own lack of activity, tells the landlord it is a difficult market. The landlord, who doesn't know enough to challenge that, accepts it. The board stays up. The details stay online. Nothing changes. And the property starts to age.
This is where the real damage begins.
Tenants and buyers who are actively looking for commercial property typically start their search three to six months before they begin viewing. By the time they walk through a door, they have seen everything available in their target area. They know the competition. They know what has been sitting there for six months and what came to the market last week. They know more about the supply in their particular niche than any agent, surveyor or accountant ever could, because they are living it every day.
When those people see a property that has been available for a long time with nothing changed, they draw a conclusion. If nobody else has taken it, there must be a reason. Maybe the landlord is difficult. Maybe there is something wrong with the building. Maybe the area doesn't work. They don't know exactly what the problem is, but they assume there is one. And they move on.
This is how blight sets in. Not dramatically, but gradually. The property that was slightly overpriced or slightly poorly presented six months ago becomes the property the market has quietly decided to ignore. The longer it sits, the harder it becomes to shift, not because the fundamentals have changed, but because perception has.
Commercial property ages in the shop window like bread, not wine. The longer it sits there, the less appealing it becomes. Unlike wine, it does not improve with time.
Douglas Parker of Montbart, an independent commercial asset manager, describes this shift with a precision worth pausing on. In the first month or two of a vacancy, passers-by are curious. They notice the empty unit, wonder what is coming, perhaps glance at the board. That curiosity is not damaging. It is neutral. But by months four to six, something has changed.
The curiosity has become what Doug calls grim observance. People are no longer wondering what is coming. They are asking themselves why it still has not been taken. And that question, asked often enough, quietly settles into an assumption. There must be something wrong with it.
Interest begins to wane significantly after around three to six months. By that point the stigma of the property that still has not been let has taken hold. Prospective occupiers assume something must be wrong — with the building, the terms, the landlord, or some combination of all three. They do not know exactly what the problem is. They assume there is one. And they move on.
The vacancy that feels static from the landlord's side of the relationship is moving through phases on the public's side — from curiosity to suspicion to dismissal. By the time dismissal sets in, the agent's job has become three or four times harder than it was at the start. Not because the property has changed. Because perception has.
Time is not neutral. The landlord who treats a property available for a year as simply one that has not yet found its tenant is misreading what is happening. Every month without a result is a month in which the pool of genuinely interested parties shrinks and the assumption that something is wrong deepens. The property is not waiting. It is ageing.
Let's be honest about something that most people in this industry won't say in public. A significant number of commercial agents are part of the reason commercial property stays empty. Not all of them. But enough that it is worth saying plainly, because landlords deserve to understand what poor agency actually looks like before they hand over an instruction and wait for results that never come.
I have worked in this industry for over two decades. I have worked in firms where poor agency was not the exception but the norm, where the culture was built around avoiding difficult conversations rather than having them, and where the measure of success was how many boards were up rather than how many deals were done. I know what bad agency looks like from the inside. I have watched it grind good people down. And I know how much it costs the landlords on the other end of it.
In a typical firm that offers both residential and commercial property services, the commercial department tends to occupy a floor or a wing somewhere removed from the main office. Away from the activity, the phones ringing, the energy of a busy residential team. The admin staff sit in an open area. The chartered surveyors have offices with doors, and the doors stay shut.
When calls come in, the surveyors don't pick them up. They are too senior for that. If a landlord calls asking for the person handling their property, the call gets put through, and nine times out of ten the response from behind the closed door is the same: Can you tell them I'm busy please.
This is not an exaggeration. I spent a significant part of my early career in firms like this, and I can tell you that the landlord waiting for a call back about their vacant property was rarely at the top of anyone's priority list. Because in a firm where the fee earners are chartered surveyors first and agents second, there is always something more urgent to deal with. Something that pays today rather than in six months' time, if it pays at all.
Commercial agency operates on a no sale, no fee basis. The agent earns nothing until the transaction completes. Not when they take on the instruction. Not when they find a tenant or buyer. Not when heads of terms are agreed. Only when contracts are exchanged and the deal is legally binding.
Think about what that means in practice. The agent invests time, effort and money from the moment they take on an instruction. Portal listings, CRM systems, phone systems, fuel costs for viewings, photography, marketing. All of it carries on regardless of the outcome. None of it gets recovered unless the deal completes.
And completion can take a very long time. Finding the right tenant or buyer might take months. Then the legal process begins, and with cheaper solicitors involved, that process can take another four to eight months. At any point during that entire period, either the owner or the incoming occupier can change their mind. The deal falls apart. The agent receives nothing. The costs carry on.
Compare that to the other professionals involved in the same transaction. The solicitor gets paid for their time regardless of whether the deal completes. The surveyor or valuer gets paid for producing their report. The agent gets nothing unless everyone else does their job properly and neither party gets cold feet.
In a firm where the fee earners have a choice between working on a property transaction that might pay in six months or might never pay at all, and completing a valuation report that generates a fee this week, the choice is not a difficult one. The valuation report wins. Every time.
This is not laziness. It is rational behaviour given the structure of the business. But the landlord with a vacant property waiting for a call back doesn't see the economics. They see silence.
Understanding this dynamic doesn't excuse poor agency. But it explains it. And once you understand it, you can see clearly what to look for when appointing an agent — and what to demand from the one you already have.
Chapters 3 to 11 cover the owner problem, the policy problem, the high street, hidden costs, what good agency looks like in practice, the legal process, what to do when it goes wrong, and the questions every landlord should be sitting with honestly.
