The phone rings on a Wednesday at 2:12 PM. On the other end is someone looking for 400 square meters of office space for a new branch office, with a budget, a deadline, and a decision to make this week. Nobody picks up. The caller waits through four rings, hangs up, and opens their browser again. Three minutes later, they're talking to your competitor.
This scenario repeats itself in commercial real estate firms every business day, but rarely does anyone translate it into hard numbers. It can be calculated, and the result usually surprises even companies that consider their phone handling well organized.
Why this hurts more in commercial real estate than elsewhere
In retail or mass-market services, a lost call is often a single sale you can make up next time. In commercial real estate the stakes are different, for three reasons.
- High value per transaction. Leasing office, warehouse, or retail space is typically a contract worth tens, often hundreds of thousands of dollars over the full lease term, not counting the potential for repeat business across future locations.
- A narrow market with real competition one call away. A company looking for space usually has a short list of specific listings and specific phone numbers it has already noted down. If one doesn't answer, the next is a click away, and a decision-maker rarely goes back to a number that failed once.
- The phone is still the first real point of contact. Despite digitization, forms, and listing portals, decisions worth hundreds of thousands of dollars are still usually started with a conversation, not by filling out a form and waiting hours for an email reply.
How many calls actually slip through, and when
Most commercial real estate firms genuinely believe they answer nearly every call. What phone system statistics usually show is different, because most missed calls aren't caused by poor organization — they're caused by the natural rhythm of the job: an agent is out doing a property viewing with another client, the phone rings in the evening after office hours, or two people try to call at the same time and the second one gets a busy signal. None of these situations is a mistake on the company's part, but each one costs exactly the same as a plain oversight.
What the cost of a missed call is actually made of
Before we calculate a concrete figure, it's worth breaking it into four components — each one a company can estimate on its own from its own data, without relying on any external industry benchmarks that rarely map one-to-one onto a specific location or market segment anyway.
- Cost of acquiring the contact. How much it costs to reach a single prospective tenant or buyer: marketing budget, listing portal commission, and the agent's time spent on research and initial outreach before a call even happens.
- Deal value, if it closes. Usually calculated as the broker's commission or the annual rent value, depending on the company's billing model.
- Call-to-deal conversion rate. What percentage of phone calls actually turn into a signed contract. This is the one factor that genuinely differs between companies, and it's worth checking in your own CRM rather than assuming a single universal figure for the whole industry.
- Missed-call rate. How many calls are actually lost each month: outside business hours, during a property viewing, while someone is on leave, or when a second incoming call overlaps with the first.
A simple formula any company can plug its own numbers into
The formula is deliberately simple, so it can be worked out in a few minutes on the back of an envelope — no spreadsheet with dozens of variables, and no consultant sending you an invoice for it.
Monthly cost of missed calls = number of missed calls per month × estimated call-to-deal conversion rate × average deal value
A company usually already has each of the three factors on the right side of the equation somewhere in its own systems — it's just rare that anyone puts them together in one place. The phone system or carrier will show the number of missed calls, the CRM will show the conversion rate, and finance (or the owner, from memory) will know the average deal value.
A worked example: a brokerage with three agents
The figures below are illustrative only, meant to show the method, not a forecast for any specific company. Every firm should plug in its own numbers from the previous section.
Sample calculation — a three-agent brokerage
~130 missed calls per month × 2–4% call-to-deal conversion × ~$3,800 average deal value:
~$9,900–$14,800 per monthEven under a conservative assumption, the lower end of this range works out to roughly $120,000 a year in lost potential revenue. This isn't a forecast for every company in the industry — it's a demonstration of the method: it's worth plugging in your own numbers and checking your own result, since depending on the scale and market segment your company operates in, it could come out both lower and considerably higher than in this example.
It's also worth noting that the same formula works in both directions. If a company cuts its number of missed calls even by half, the result doesn't drop proportionally to zero — it drops to half the calculated figure, which in the example above still means tens of thousands of dollars a year, this time on the revenue side rather than the loss side.
The cost you won't find in any spreadsheet
Beyond the lost transaction itself, there's a second side to this problem — harder to quantify, but just as real. A corporate client looking for space judges a company's professionalism from the very first contact, and a missed call in a B2B relationship is often read as a signal about the whole organization, not just one person's momentary workload. In an industry where recommendations and opinions circulate among the same handful of players, that's a reputational cost that's hard to translate directly into dollars, but that compounds over time with every additional missed call.
How to work this out for your own firm: four steps
- Check with your phone system or carrier how many calls per month actually go unanswered. Most modern phone systems show this directly in their statistics, with no extra configuration needed.
- Check your CRM for what percentage of phone contacts in your company actually turn into a signed deal, instead of assuming a figure from an article like this one.
- Work out the average deal value your company actually earns per signed lease or sale, averaged over the last dozen or so months.
- Plug those three numbers into the formula from this article, check your own result, and then decide whether it's worth acting on.
What you can actually do about it
There are several solutions, and they differ in effectiveness and cost. It's worth knowing all of them before settling on one, because none of them is universally the best choice for every company size.
An extra person on reception or the phone line
Effective during standard business hours, costs the employer roughly a few thousand dollars a month fully loaded, and doesn't solve the problem outside business hours or during time off and sick leave.
Forwarding calls to an agent's mobile phone
Zero implementation cost, but in practice often fails: an agent in the middle of showing a property to one client simply won't pick up a second call — and if they do, it interrupts the client who's already on site.
An automated answering service or voicemail
Cheap and simple to set up, but most B2B callers hang up rather than leave a message and wait for a callback, so in practice it's not much different from no answer at all.
Outsourcing the phone line to an external call center
Effective at high call volumes, but relatively expensive for a smaller, few-person firm, and requires handing an external team knowledge of your current listings.
An AI-powered voice assistant
Answers every call twenty-four hours a day, holds a natural conversation, provides information about available space, can book a viewing directly in a calendar, and — if the matter needs a human — transfers the call live to a specific, designated person at the company. Solutions of this kind, such as voice.oriondial.com, are increasingly showing up as a complement to the team, especially where the phone rings outside standard hours or agents spend most of the day in the field.
Frequently asked questions
Does every commercial real estate company actually lose real money on missed calls?
Not every one, and not to the same degree. Companies with a low monthly call volume, or with well-staffed round-the-clock reception, may find this problem marginal. The only way to know is to work out your own numbers using the formula in this article, rather than assuming either scenario upfront.
If a prospect can't get through once, will they definitely never call back?
Some callers will try again, but a significant share — especially in B2B — simply move on to the next item on their list, since they usually have several alternatives to check the same day.
Is it worth calculating the cost of a missed call if a company only gets a handful of calls a day?
Yes, because given the high value of a single transaction in commercial real estate, even one or two lost calls a month can add up to a figure worth knowing before making any decision about changing how you handle your phone line.
Summary
A missed call at a commercial real estate firm rarely shows up on a cost sheet, because it doesn't generate an invoice or any document anyone has to book. And yet, as the example above shows, over a year it can cost more than many a company's entire marketing budget. The biggest risk here isn't the fact that the phone sometimes rings unanswered — it's that most companies never check how much that actually costs. It takes a piece of paper, four numbers, and five minutes to change that, and it's a lot easier to decide what to do next when you know the actual figure, rather than just a hunch that the problem exists somewhere.
