At Corzly, we’ve managed well over 50,000 guests across dozens of properties in multiple cities. Through this experience, our team has learned that guest screening isn’t just important. It’s essential to protecting your property, maintaining your sanity, and keeping your short-term rental business running smoothly.
But difficult guests don’t just appear out of nowhere. They announce themselves through their booking patterns, communication style, and behavior long before they ever step foot in your property.
Guest screening can truly make or break your short-term rental business. When you get it right, you protect your property from damage, avoid stressful situations, and maintain positive relationships with your neighbors. When you miss the warning signs, you’re setting yourself up for problems that could have been prevented.
Most of these red flags are visible from the very beginning, often in the guest’s first message or booking behavior. You just need to know what to look for.
The 9 Red Flags We Always Watch For (#9 is VERY IMPORTANT)
Red Flag #1: Negative or Concerning Prior Reviews
This one seems obvious, but you’d be surprised how many hosts don’t check reviews on instant booked reservations.
What to do: Check the guest’s review history. Sometimes the truth is written right there in plain sight. Previous hosts may have flagged issues with house rules, cleanliness, or behavior.
If you spot concerning reviews and the guest instant-booked your property, contact platform support immediately. Explain that you’re not comfortable with their past behavior. This is one of the few legitimate reasons platforms will allow you to cancel without penalty.
Red Flag #2: Incomplete Profiles
An incomplete guest profile: no photo, minimal information, no verification—should immediately raise questions.
While online travel agencies claim to conduct thorough background checks, we all know the reality. They’re not going to catch 100% of problematic guests. That’s why you need to do your own verification.
Our approach: We always require a government ID before check-in for every reservation. This isn’t negotiable.
Think about it: when someone stays at a hotel, showing ID is standard practice. Your short-term rental should be no different. If a guest pushes back or refuses to send their ID, that tells you everything you need to know about how they’ll behave during their stay.
Pro tip: Make sure your rental agreement or house rules clearly state that ID verification is required before check-in. This gives you grounds to cancel penalty-free if a guest doesn’t comply.
Red Flag #3: Zero or Inconsistent Communication
Most guests follow a predictable communication pattern. They’re typically most active when they first make the reservation and then again a few hours before check-in.
If there’s no communication when trying to verify something suspicious like a party, that’s a problem.
Why this matters: Guests who won’t communicate before arrival often won’t communicate during their stay either—and that’s when issues escalate. Whether it’s unauthorized guests, undisclosed pets, or other rule violations, poor communicators tend to be problem guests.
If your house rules clearly outline communication requirements (this is also an Airbnb rule) and a guest isn’t responding, you have legitimate grounds for cancellation.
Red Flag #4: Oversharing Personal Information Upfront
We understand that guests come from all walks of life and may be dealing with difficult situations—divorces, family losses, job relocations, personal struggles.
But when someone leads with their entire life story before they’ve even booked, and none of it relates to their actual stay, it’s often a warning sign.
What we’ve learned: Guests who overshare personal drama upfront tend to be more emotionally demanding during their stay. They may have unrealistic expectations, require excessive reassurance, or become difficult to manage if anything goes wrong.
This doesn’t mean you should reject everyone going through a tough time. It just means you need to pay attention when someone’s communication focuses heavily on personal issues rather than the practical details of their reservation.
Red Flag #5: Excessive, Detailed Questioning
Yes, your listing should answer common questions clearly. And yes, most guests don’t read listings as thoroughly as they should.
A few clarifying questions are completely normal. But there’s a difference between normal questions and excessive interrogation about minute details.
Examples of concerning questions:
- “What thread count are the sheets?”
- “What’s the exact square footage of the bathroom?”
- “What brand of cleaning chemicals do you use?”
- “What color are the lightbulbs in the bedside lamps?”
When a guest is this fixated on tiny details before they’ve even arrived, you’re getting a preview of how demanding they’ll be during their stay. These are often the guests who will complain about everything, leave negative reviews over minor issues, or require constant attention.
Red Flag #6: Pushing Boundaries on Your Rules
Pay close attention to guests who try to negotiate your house rules before booking.
Common examples:
- Your property sleeps 4 people, they want to bring 6 or 8
- You allow one dog under 25 pounds, they ask about bringing two 50-pound dogs
- Check-in is at 4 PM, they request 10 PM arrival
- You have a no-party policy, they ask about having “just a small gathering”
Why this matters: When guests push boundaries before they arrive, they’re showing you they’ll push even harder once they’re in your property.
Now, context matters here. A property that sleeps 12 and someone asking to bring 13 is very different from a studio that sleeps 2 and someone wanting to bring 4 additional people.
But as a general rule, guests who don’t respect your clearly stated rules upfront are unlikely to respect them during their stay. And if you’re flexible on your rules before they arrive, they’ll often take advantage and push even further.
Our recommendation: If someone is trying to bend major rules, politely decline or direct them to a property that better fits their needs. And yes, if they book anyway despite you saying no to their request, check your security cameras when they first arrive.
Red Flag #7: Excessive Flexibility Requests on Check-in/Check-out
This red flag is closely related to #6, but it’s worth highlighting separately because it’s so common.
You have a check-in window that ends at 8 PM, but a guest asks to arrive at 9 PM. Seems reasonable, right? Here’s what we’ve found from managing hundreds of properties:
When you’re flexible upfront, guests push further. Someone who says they’ll arrive at 9 PM (when your limit is 8 PM) often shows up at 10, 11, midnight, or even 1 AM.
This creates several problems:
- Your cleaning team can’t prepare the property on schedule
- Neighbors may complain about late-night arrivals
- Key exchanges become complicated
- You or your team lose sleep waiting for late arrivals
Special circumstances: Some properties genuinely have more restrictive check-in requirements. For example, we manage a property in Brazil with biometric entry that requires an in-person key exchange. For that property, we accept check-ins until 8 PM, but we get requests all the time for later arrivals.
The solution? Set your boundaries clearly and stick to them. If you make exceptions, do so rarely and with clear, agreed-upon time limits.
Red Flag #8: Uncertain Travel Plans
We always ask guests why they’re visiting and what time they expect to arrive. It’s a simple screening question that reveals a lot.
Red flag responses:
- “Not sure yet”
- “We’ll figure it out when we get there”
- “Plans might change”
- Constantly shifting arrival times or trip purposes
If someone is flying in from another city, they should have some idea of their flight schedule. If their plans are vague and uncertain upfront, that often leads to:
- Last-minute reservation changes
- Cancellation disputes
- Requests for refunds based on “miscommunication”
- Unclear expectations about their stay
Vague travel plans usually mean vague guests—and vague guests tend to cause problems.
Red Flag #9: Local Guests (The Big One)
This is perhaps the most important red flag, and it’s also the trickiest to navigate.
The question you need to ask: Why does someone who lives 15-20 minutes away need to rent your property for the weekend?
The reality: Most of the time, locals want to use your property for something they don’t want to do at their own home. This could be:
- Throwing a party
- Hosting an event that violates your rules
- Having more guests than allowed
- Activities that could damage your property
Important note: You cannot legally discriminate against local guests. Airbnb and other platforms are very clear about this. However, you can ask questions.
Our approach: Include language in your house rules that says: “If you’re a local resident, please contact us first before booking so we can gather additional information about your stay.”
This gives you the opportunity to:
- Ask why they need the property
- Clarify house rules upfront
- Assess whether their plans align with your property’s use
- Decline if their answers raise concerns
Yes, there are legitimate reasons locals might need a rental—home renovations, family visiting, property issues, special occasions. We’re not trying to exclude everyone. But this screening step helps separate genuine guests from potential problems.
How to Use These Red Flags Effectively
The more red flags you spot together, the more likely you’re dealing with a difficult guest.
One red flag alone? Maybe not a dealbreaker. But if you’re seeing three, four, or five of these warning signs in a single reservation, trust your instincts.
Best practices for guest screening:
- Document everything in your house rules. Make your requirements crystal clear—ID verification, communication expectations, occupancy limits, pet policies, check-in windows. When these are properly documented, you can cancel penalty-free if guests don’t comply.
- Respond to red flags immediately. Don’t wait until the day before check-in to request ID or ask clarifying questions. The sooner you spot issues, the more options you have.
- Use instant book strategically. If you use instant booking, make sure your settings require verified IDs and positive reviews. You can always add additional screening after the booking is confirmed.
- Set up proper systems. Whether you manage properties yourself or work with a management company, you need reliable systems for guest verification, communication tracking, and screening protocols.
- Trust your gut. If something feels off about a reservation, there’s probably a reason. We’ve learned to trust those instincts after 50,000+ guest interactions.
Thankfully, difficult guests are actually pretty rare.
When you’re properly screening reservations and watching for these nine red flags, problematic guests become even rarer. Most of your guests will be wonderful people who respect your property, follow your rules, and leave positive reviews.
Guest screening isn’t about being suspicious of everyone. It’s about being smart and proactive, catching the small percentage of problem reservations before they impact your business.
