A vacant space makes calls whether or not anyone is answering.
An empty suite is not passive. From the day the panel goes up it is generating inbound — from people driving past, from the flyer, from the portals, and from everyone who scrapes the portals. That continues, every week, until it leases.
Somebody is answering those calls, or nobody is. Either way that was a decision about the listing, and on most assignments it never gets made deliberately.
How it usually gets decided
By whatever number was easiest to put on the sign. Often a cell, because it is the one you know by heart and the sign order was due. Sometimes a main office line that rings a desk nobody sits at any more. Sometimes a portal's masked number that routes to an inbox checked twice a week.
None of those were chosen against the question of what a drive-by caller needs. They were chosen because a number had to go in the box.
What the vacancy is actually costing
This is the arithmetic worth doing on your own numbers rather than accepting from a vendor. Take the monthly rent on the space. Every month it sits empty, that is the carry — to the owner directly, and to you as a commission that has not happened yet.
Against that, count how many calls the listing gets in a month and guess honestly at how many were answered. On most retail suites with a sign up, it is not a small number of calls and it is not a high answer rate. You do not need many of the missed ones to have been real for the answer to be obvious.
The point is not that every missed call was a tenant. Most were not. It is that a vacancy is expensive enough that even a low hit rate on the ones you are currently dropping is worth more than the cost of catching them.
Making it a decision
When a space goes to market, the number goes on the list with the photos, the flyer, and the portal syndication. It is a piece of the marketing package, not a phone setting.
It belongs to the listing, so it goes on every surface — panel, flyer, OM, LoopNet, Crexi, property site — and it comes down when the space leases. One number, one screen, one place all the inbound on that assignment lands.
$99/mo per listing. Cancel when it leases.
Questions brokers ask
Who should answer calls on a vacant commercial space?
Somebody who knows the space. The caller is asking about suite sizes, uses, and timing on one specific property, and a message taker cannot answer any of it.
Is it worth it on a small vacancy?
That depends on what the vacancy costs the owner every month it sits, not on what the space rents for. Even a low hit rate on calls you are currently dropping is worth more than the cost of catching them.
What happens to the calls that are not tenants?
Filed, not forwarded. You can look at the volume when you want to; it does not reach your phone.
