Property management has weeks like this. Nobody posts about them.
It started with a pest report. A prospective tenant came to view a vacant basement unit at one of our properties. He happened to be an entomologist — someone who studies insects professionally. He did not take the apartment. What he left behind was a precise identification: German cockroaches, living in the wood and cardboard in the basement, in numbers that required a professional exterminator — not a spray can from the hardware store.
We called pest control. We coordinated prep instructions across everyone in the building: empty all cabinets above and below in the kitchen and bathroom, no open food, no garbage, vacate for four hours after treatment. That coordination alone — across multiple tenants, a property manager, and an on-site contact — took three days of back-and-forth messages.
The exterminator came, did the work, and handed the key to our commercial unit to our property manager on the way out.
This is where things got complicated.
The missing key
The commercial space on the ground floor was leased to a business tenant. They had a scheduled access appointment. Our property manager had the key — the exterminator had handed it directly to him — but by the time the tenant arrived, the key was gone.
They came back the next day. Still no key.
They came back a second time with their crew. Still no key. Workers had to be sent home. It cost them time and money. The tenant called me directly. We were in breach of the lease.
Nobody was lying. The key had been mistaken for an old key to a lock that had recently been changed, assumed to be the wrong key, and set aside. By the time we traced the chain — exterminator to property manager to confusion over old lock versus new lock — three days had passed and two appointments had been missed.
What this actually cost
The cockroaches cost us a fumigation, some coordination stress, and a temporarily disrupted basement. Fully recoverable.
The key cost us a commercial tenant relationship, two missed appointments, a breach conversation, and the kind of reputational damage with a business client that is harder to repair than a broken lock.
The pest issue was a discovery. The key issue was a system failure. Those are very different things.
A discovery you respond to. A system failure means the system was never built properly in the first place — and the only way to fix it is to build the system.
What we changed
Every space now has its own numbered lockbox. Codes are known only by the minimum number of people who need them. No key leaves a lockbox without a clear record of who has it and when it comes back. It sounds like more overhead than it is — in practice it takes about ten minutes to set up and almost no time to maintain.
The rule is simple: the key lives in the box. Always. The moment someone needs to take it out, they confirm where it is going and when it returns. No exceptions, no assumptions, no handing keys to whoever is nearest on their way out the door.
On the wider point
Property management is not passive. It is not a machine you build and walk away from. It is a series of small operational decisions, and the ones you defer are the ones that become crises.
The pest issue could have been worse — we caught it because a knowledgeable person walked through the building and told us exactly what we had. Most landlords would have bought a spray can and hoped for the best. German cockroaches in walls and cardboard do not respond to spray cans. They needed heat treatment and professional intervention.
The key issue could have been worse — it was a commercial tenant with a lease, not an Airbnb guest who could leave a one-star review and disappear. A commercial tenant has legal standing. The conversation about breach was uncomfortable enough; it could have become much more.
Both were recoverable. But only because we were paying attention and moved quickly once we understood what had happened.
If you own rental property — residential, commercial, or mixed — get your operational systems built before you need them. A lockbox protocol, a key log, a clear chain for who holds what. It takes an afternoon. The week you actually need it is not the week to build it.
The cockroaches, by the way, are gone.
