What Are Ghost Listings? The Short-Term Rentals Hiding in Plain Sight

Like vampires, some short-term rental listings only come out after dark.

A property appears on a rental platform in the evening and is gone by the time a compliance officer starts work the next morning. The next night, the property reappears, ready to accept bookings from prospective guests while remaining largely invisible to monitoring that happens during business hours.

These properties, sometimes called “ghost” or “vampire” listings, are short-term rentals (STRs) that appear online only during certain hours, often at night or outside normal government operating hours. By systematically publishing and removing listings, operators may be able to avoid detection while continuing to rent their properties without the registrations, licenses, or tax obligations required by their jurisdiction.

In a Cornell Journal of Law and Public Policy study, researchers Keri K. White and Jennifer Cordon Thor examined five mid-sized tourist cities, each with an active registration requirement. Across the cities where listing data could be verified, between 25% and 75% of short-term rentals carried no posted registration number. The authors note the real figure is likely higher: expired and fraudulent registration numbers are easy to post and difficult to verify without cross-referencing city records.

For local governments that have invested significant time and resources into creating STR ordinances, the practice exposes a difficult reality. An ordinance reaches only the properties governments know exist. With the STR market becoming more sophisticated, effective compliance increasingly depends on whether governments can see the same market their residents and visitors see, regardless of the time of day.

Why Ghost Listings Are So Difficult to Detect

STR platforms have created an unusually dynamic market for local governments to oversee. Listings can appear across multiple platforms, change names, use approximate locations, temporarily go inactive, or reappear later. Unlike a hotel or traditional business with a fixed physical presence, a short-term rental’s digital footprint can change almost instantly.

That flexibility is what makes ghost listings possible. As White and Thor put it, hosts “can easily list and de-list homes on STR platforms, creating a constantly changing regulatory environment that traditional enforcement methods cannot match.”

An operator attempting to avoid detection may make a property available when government offices are closed and remove or deactivate the listing before normal working hours resume. To a traveler searching for a place to stay at 9 p.m., the rental is very real. To a compliance team reviewing short-term rental listings the following morning, it may effectively not exist.

That creates a fundamental visibility problem. If a jurisdiction relies on manual searches, complaints, or monitoring that occurs on a predictable schedule, it may capture only a partial view of its short-term rental market rather than a complete one.

The more frequently listings change, the less reliable that view becomes. Governments may believe they know how many STRs are operating within their borders while an unknown number remain active outside the windows in which officials typically look for them.

What Goes Undetected Goes Uncollected

Finding an unregistered STR is rarely the end goal of a compliance program. Local governments need that information to determine whether operators are following local requirements around registration, licensing, taxation, zoning, occupancy, and other rules established by the jurisdiction. When properties escape detection, those processes never begin.

An unidentified operator may avoid registration fees or required permits. Depending on the jurisdiction, the property may also generate rental income without remitting applicable lodging or occupancy taxes. Over time, even a relatively small number of undetected properties can create a meaningful gap between the STR activity occurring within a community and the revenue the government actually collects.

The financial implications extend beyond the STR program itself. Lodging and tourism-related taxes often support services and priorities that benefit the broader community. When taxable activity goes unidentified, local governments have fewer resources available to put toward those needs.

More importantly, the problem can compound. A property that remains invisible for one night may remain invisible for months if the same monitoring approach continues to miss it. Without a more complete view of market activity, governments may have no way of knowing how large the gap has become.

Compliant Operators Pay the Price

Another consequence is harder to quantify but just as important: fairness.

Many STR operators follow the rules. They register their properties, obtain required licenses, collect and remit applicable taxes, respond to government communications, and pay the fees associated with operating legally.
When another operator can avoid those same obligations simply by making a listing harder to find, compliant property owners are placed at a disadvantage.

Registration fees and taxes become costs that rule-following operators pay while noncompliant competitors do not. Over time, inconsistent application can also weaken confidence in the STR program itself. Operators who have made the effort to comply may reasonably question why they alone are absorbing the cost of compliance when others appear able to operate outside the system.

Effective STR compliance therefore has implications beyond maximizing revenue. Consistency helps local governments demonstrate that the same rules apply across the market and that compliance is expected from every operator, not simply the easiest ones to identify.

That distinction matters for the credibility of an STR program. Regulations are far more effective when property owners believe they will be applied consistently.

Government Offices Close. Online Marketplaces Don’t.

Travelers search for rentals early in the morning, during lunch breaks, late at night, and throughout weekends and holidays. Hosts can update availability, modify listings, or change how a property appears online just as easily.

Trying to oversee that environment through manual searches alone creates an inherent mismatch. Even a diligent compliance team cannot continuously search every platform at every hour of the day, nor is that a productive use of limited staff resources.

Predictable monitoring can create another vulnerability. If listings are consistently reviewed at similar times, operators who understand that pattern may have an opportunity to work around it. A process designed to identify noncompliance can inadvertently become easier to evade simply because its timing is known.

The answer is not asking compliance officers to work around the clock. Instead, it calls for monitoring that better reflects the environment they are responsible for overseeing. Technology can continuously gather and compare STR listing data across different times, helping to surface properties that disappear before a traditional workday begins.

Detection Improves When the Timing Changes

Identifying ghost listings requires governments to move beyond a single, predictable view of the market.

Modern STR monitoring technology can use automated web crawling and data matching to identify active rentals and compare those listings against government registration and licensing records. When monitoring occurs at staggered times, local governments gain visibility into listings that may only appear during evenings, weekends, or other periods when manual compliance efforts are unlikely to be underway.

That broader view makes it much more difficult for a property to remain invisible simply by changing when its listing appears.

The right solution can also help governments turn discovery into action. Once a potentially unregistered property has been identified, staff need to determine its location, compare it with existing records, communicate requirements to the operator, track its compliance status, and, when necessary, connect licensing information with tax obligations.

Bringing those processes together reduces the risk that a listing is discovered but then lost somewhere between identification and follow-through.

A Complete Inventory Informs More Than Compliance

Accurate identification creates value well beyond catching an operator attempting to avoid registration. A reliable inventory of active STRs gives government leaders better information about what is happening within their communities. They can understand where rentals are concentrated, compare active properties with registration records, identify patterns in noncompliance, and make more informed decisions about staffing, outreach, compliance, and policy.

That visibility becomes increasingly important as an STR program matures. A community with a small number of occasional rentals may be able to rely heavily on manual oversight. As the market grows, however, listings become more difficult to track across platforms, and the distance between what staff can manually observe diverges from what is actually happening.

More complete data also helps local governments distinguish between different types of STR issues. An unregistered property presents a licensing problem. Unpaid lodging taxes create a revenue compliance issue. Noise or parking complaints may require a separate response. Understanding which properties are active and connecting them with the appropriate records provides a stronger foundation for addressing each issue appropriately.

Consistency Builds Community Trust

STR regulations often sit at the intersection of competing interests. Visitors want places to stay. Property owners want the ability to generate income. Neighbors want safe, livable communities. Local governments must balance those priorities while administering regulations fairly and efficiently.

Inconsistent oversight can make that balance more difficult. Residents may lose confidence when they repeatedly see a nearby property operating as an STR but cannot find evidence that it is registered. Compliant hosts may become frustrated when competitors appear to avoid fees or taxes. Government staff can spend significant time responding to complaints about properties that were never captured through existing monitoring efforts.

A strong compliance program creates greater transparency for everyone involved. Local governments know which properties are operating. Owners understand what is required of them. Residents have clearer channels for raising concerns. Compliance teams can focus their attention where it is actually needed.

Technology alone cannot create trust, but reliable information makes consistent administration possible. Consistency is one of the strongest signals a local government can send that its STR rules are more than requirements on paper.

Ghost Listings Don’t Have to Stay Invisible

Ghost listings expose a larger challenge facing modern STR programs. Jurisdictions are overseeing a market that can change by the hour.

A short-term rental property does not stop operating simply because its listing disappears before the workday begins. The booking activity, potential tax obligations, neighborhood impacts, and regulatory requirements remain. When monitoring captures only a portion of that activity, local governments are left administering their ordinances with an incomplete picture.

Closing that distance requires a compliance strategy designed for the way the STR market actually operates. Automated identification, varied monitoring schedules, data matching, centralized registration and licensing information, and clear compliance workflows can give staff a more complete view without requiring around-the-clock manual oversight.

For governments, that visibility creates consistency, something increasingly difficult to achieve in a fast-moving online marketplace. Compliant operators can compete on a more level playing field, jurisdictions can better protect the revenue their ordinances account for, and staff can apply local requirements based on what is happening in their communities. Ghost listings may be designed to disappear, but a modern STR compliance program can make sure they do not stay hidden for long.
