Buyers Who Leave Lights On, Doors Unlocked, and the Garage Open After a Showing

You cleared out for the showing, drove around for an hour, and came back to find the house exactly as you left it except for one thing. Or several things. Every light in every room is on. The back door that you specifically remember locking is standing unlocked. The garage door is up and has been up for an hour while you were gone. Nothing was taken. Nobody lingered on purpose. The buyers and their agent simply walked out the way people walk out of a place that is not their home, without thinking much about what they left behind.

It sounds minor until you add it up across a listing period with multiple showings per week. Here is what this costs sellers and what can actually be done about it.

The Lights

Leaving lights on after a showing is the most universal version of this complaint. Sellers who leave lights on for showings, which is standard practice because a well-lit home shows better, come home to find that the buyers turned on additional lights in rooms they visited and left all of them on when they walked out. On a summer afternoon in Lubbock that is an inconvenience. Over the course of a listing with showings multiple days per week it is a real addition to the electric bill that the seller pays while someone else decides whether to buy their home.

The practical response is simple. Showing instructions that ask buyers and their agents to turn off any lights they turned on before leaving are worth including. Most buyer's agents will communicate this. Some will comply. The ones who do not are largely unavoidable without a more active solution, which for some sellers means smart lighting that can be checked and controlled remotely through their phone without having to come home and do it manually.

The Unlocked Doors

This one carries a security dimension that the lights do not. A back door or side door left unlocked after a showing is an entry point that has been left open to anyone who tries it between the time the buyer left and the time the seller returned. Most of the time nothing happens. That does not make it acceptable and it does not make it not a security concern. Sellers who have had this happen repeatedly describe a feeling of vulnerability that is disproportionate to the actual incident because the home is supposed to be secured and someone else's carelessness undermined that.

Showing instructions that specifically ask agents to verify all doors are locked before leaving are worth including for this reason. A lockbox that controls the key and an agent who is professionally accountable for the showing creates a clearer chain of responsibility than an unlocked door and a shrug. When an unlocked door happens once it is an oversight. When it becomes a pattern with the same agent it is worth a direct follow-up call.

The Garage Door

An open garage door after a showing is the most visible version of this problem and the one that carries the most combined exposure. An open garage is an invitation to look inside and potentially enter the home through the interior garage door, which is not always as secured as the exterior doors. A garage door that has been open for an hour while the seller was out means anyone passing by had a clear view of the contents and an easy path to the entry point.

Sellers who provide garage access for showings, either through a code or through the lockbox, should specifically note in showing instructions that the garage door must be closed and the interior garage door must be confirmed locked before the agent leaves. This is not paranoia. It is standard security practice for a home that is being shown to strangers on a regular basis.

Why It Keeps Happening

Buyer's agents who manage multiple showings in a day are often moving quickly between properties and the mental checklist for exit protocol at a home that is not yours is not as automatic as it is at your own home. The seller has a routine for leaving their own house. The buyer's agent does not have that same ingrained habit for a home they have visited once. That does not excuse the oversight but it explains why it is so common and why the solution is clear, explicit instructions rather than assuming professional courtesy will cover it.

How I Address This for My Sellers

Every listing I manage includes exit protocol in the showing instructions. Turn off any lights you turned on. Verify all exterior doors are locked. Close and confirm the garage door before leaving. These are three sentences that most agents read and follow. For sellers who have smart home technology I walk through how to use it to check and control these things remotely so they do not have to drive home to verify the showing left the home as it should be.

If you are selling your home in Lubbock or West Texas and you want showing instructions that include exit protocol alongside all the other expectations, that is a standard part of how I prepare every listing. The goal is a showing experience that works for both the buyer and the seller and that means the home should be in the same secure condition when they leave as it was when they arrived.

The Bottom Line

Lights left on, doors left unlocked, and garage doors left open are all the result of buyer's agents and buyers leaving a showing without the same exit habits they would have at their own home. Clear exit protocol in the showing instructions eliminates most of this before it becomes a pattern. It is not about assuming the worst of buyers. It is about recognizing that people do not automatically treat someone else's home the same way they treat their own and setting clear expectations bridges that gap before the seller comes home to a house that has been open to the world for an hour.
