breathe happy. good evening. thanks for joining us. we begin tonight with some horrifying rental disasters. if you're thinking of having a

mini vaca in someone else's home or letting a stranger stay in your this is summer, listen up. here's gio benitez. >> reporter: you're watching a home burglary in action, police say, but this is no break in. this woman actually rented out this home from its owner on airbnb. the guest turned alleged burglar caught on surveillance camera, stealing over $35,000 in valuables, according to authorities, after being told to stay out of the locked closet and office. >> she basically the doorknob and door itself. >> reporter: theft is just one nightmare for homeowners. >> this is awful. >> reporter: mark and starr king, parents to two young sons headed over the keys to their calgary home to rerntss who were supposedly in town for a wedding. >> anything imaginable that would violate a home has happened here. >> reporter: according to

neighbors, the guests started their own party. >> within three or four hours that we exchanged keys, a party bus was here. >> reporter: a party that lasted several days and left their once-immaculate home unrecognizable. >> we don't want to touch anything. broken glass everywhere. there's barbecue sauce on the ceiling. >> reporter: the total amount of damage, roughly $50,000 worth. according to the kings. air airbnb covers up to $1 million in property damage and they say that situations like this are incredly rare but we have zero tolerance for this kind of behavior. but sometimes those nightmares can play out while you're still at home. >> worst thing i've ever spearsed. >> reporter: she rented out her master bedroom but agreed to switch to cash-only payments.

and that's when trouble started. >> i asked, it's time for you to go. >> reporter: but her renters refused to leave. and that's when she installed these security cameras. her unwelcome guests helped themselves to anything in her refrigerator and cabinets. this man is seen wandering through the house at night. >> in a lot of states, if you stay in a place for at least 30 days, it's deemed to be a rental. to get someone out who doesn't want to leave, you effectively have to evict them. >> reporter: ultimately, the owner paid them more than $1700 to gts them to leave her house rather than engage in a potentially lengthy evision process. >> these laws are generally intended to prevent people for losing their homes, from getting kicked out on a day's notice. they're not supposed to be for people who want to stay longer

for an airbnb rental. most of the time the system works, but it takes just a few people exploiting the system, stealing, damaging, staying, fighting, to make everyone worry about renting out their home. >> reporter: despite these horror stories, airbnb is growing in popularity. there are 1.5 million listings nationwide. and 40 million guests have booked a place. >> not only renting my places but other enabling other people to get into the industry and start to make some extra income. >> reporter: scott shatford is an airbnb host. >> one thing is really selling yourself. >> reporter: he's made a six-figure salary renting multiple properties in the santa monica area to over 1,000 people, even writing an e-book on the subject. >> and they want to like you just as much as they want to like the place that they're

staying at. >> reporter: he says airbnb can be safe and ruk rative. beware of last-minute bookings. >> i tend to scrutinize more, people that are staying at my property that live in my same city. because i, i know they're not going on vacation. i don't really know what the purpose of their travel is. >> reporter: also, set up your airbnb account so that only experienced, verified renters can book your place. >> this is really, really important. because if somebody trashes your house or steals your stuff, you know exactly who you're going to be chasing down. >> reporter: and finally, doing some social stalking. >> if, you know, the picture on facebook of your guests is, you know, somebody doing a keg stand, you probably don't want them coming to your spring break rental, right? >> reporter: when it comes to

home renters renters should beware too. >> this house is amazing. how could that be? and i thought maybe we were lucky. >> reporter: aseemingly perfect vacation home for cherry mchalfry's extended family, 14 members, her husband and daughter were the first to arrive. >> kind of like a bali style. >> reporter: followed shortly by the actual homeowner. >> i took a peek through the slats of this window here and recognized there were total strangers in my house. >> all of a sudden, we saw a man come in. >> the little girl sort of screamed. >> i was kind of surprised. i didn't know who it was. >> i informed them that i was the owner of the house. >> he basically said, sorry to tell you this, but you guys have been scammed. >> reporter: turns out. the mchalfries fell for a fake listing.

less than one in 10,000 listings are fake. all sides of this growing rental business ripe for ex-employ tarks but at least one alleged thief is no longer a threat. >> she was quickly and easily recognizable by one of our investigators who put it together and once we were able to see her photo and match it with the video surveillance, you could tell that it was her. >> reporter: the suspected sticky-fingered san francisco renter in police custody tonight. for "nightline," i'm geoba knee tez in new york. up next, the site pairing up women looking for men. plus, we're with one direction, opening up about the changing story of their lives.

the story of my life hn's disease is tough, but i've managed. except that managing my symptoms was all i was doing. and when i finally told my doctor, he said humira is for adults like me who have tried other medications but still experience the symptoms of moderate to severe crohn's disease. and that in clinical studies, the majority of patients on humira saw significant symptom relief. and many achieved remission. humira can lower your ability to fight infections, including tuberculosis. serious, sometimes fatal infections and cancers, including lymphoma, have happened; as have blood, liver, and nervous system problems, serious allergic reactions, and new or worsening heart failure. before treatment, get tested for tb. tell your doctor if you've been to areas where certain fungal infections are common, and if you've had tb, hepatitis b, are prone to infections, or have flu-like symptoms or sores. don't start humira if you have an infection. ask your gastroenterologist about humira. with humira, remission is possible.

you can't put two in one. at intel, they make technology that lets a device be a laptop and a tablet, so you can put two in one. no, you can't. can. can't. can. upgrade to a 2in1 with intel. i sure had a lot on my mind when i got out of the hospital after a dvt blood clot. what about my family? my li'l buddy? and what if this happened again? i was given warfarin in the hospital but i wondered if this was the right treatment for me. then my doctor told me about eliquis. eliquis treats dvt and pe blood clots and reduces the risk of them happening again. not only does eliquis treat dvt and pe blood clots, but eliquis also had significantly less major bleeding than the standard treatment. knowing eliquis had both... turned around my thinking.

don't stop eliquis unless your doctor tells you to. eliquis can cause serious and in rare cases fatal bleeding. don't take eliquis if you have an artificial heart valve or abnormal bleeding. if you had a spinal injection while on eliquis call your doctor right away if you have tingling, numbness, or muscle weakness. while taking eliquis, you may bruise more easily... and it may take longer than usual for bleeding to stop. seek immediate medical care for sudden signs of bleeding, like unusual bruising. eliquis may increase your bleeding risk if you take certain medicines. tell your doctor about all planned medical or dental procedures. eliquis treats dvt & pe blood clots. plus had less major bleeding. both made switching to eliquis right for me. ask your doctor if it's right for you.

>> reporter: they are seeking for help from this online dating site that pairs attractive women with generous males who foot the bill for trips all over the world. >> i'm 21. i'm a junior at tulane university. >> reporter: kes has no intention of telling her parents that she's about to spend the weekend in miami with a guy she's never met. >> my dad might have an issue with it, because i'm his only girl. and he loves me, and he, like, wants to make sure i'm safe. >> reporter: she feels pretty comfortable since she's been chatting with dave for a couple weeks now. when kes arrives it's well past 1:00 in the morning. she's having last-minute doubts. >> if he doesn't look like he's supposed to, i'm literally sprinting for the hills. >> reporter: kes is pleasantly surprised. >> you took forever. >> i blame the flight, mainly. >> reporter: it's late, till they head for their separate rooms for the night.

the next day, kes sleeps in past noon, and dave is waiting for hours. >> now, like a whole day, a few hours. >> nice. >> reporter: she meets him for lunch, and the two start hitting it off. >> that's awesome. >> yeah, you have to make friends with people who make the drinks. >> reporter: dave has paid for this romantic get away, so their arrangement poses an obvious question. that's a pretty significant outlay of cash. >> it depends on your income. >> reporter: there's no of expectation? >> it's nothing like a sugar baby/sugar daddy kind of thing. >> reporter: you really think there are no expectations. >> i mean i have laid down my laws and morals. >> reporter: that night at the bar. conversation isn't flowing as freely as the drinks. kes seems more interested in

other men. they hop for the cab, heading for a club. kes doesn't seem to be digging the date. >> i live in santa monica. >> reporter: you have to wonder if this date is living up to dave's expectations. >> a lot of people think wow, they're taking advantage of young women. when in reality, the opposite could be true. >> reporter: browsing through over the 6,000 profiles, we found people hoping to find a match but also millionaires looking for no-strings-attached fun and women seeking support. some people say it's akin to an escort service >> sometimes the guy will pick up the tab and sex might evolve. and do we equate the dinner that he pays as the monetary exchange for sex? >> reporter: even if dave secretly hopes for a hookup, his prospects aren't looking good.

kes is sick.

how long had that been in the works? >> we'd never done that before. we wanted to drop it and see ha what happened. it's fun. it's almost aggressive. it's kind of a little dirty. >> reporter: "drag me down", now joins other massive hits like "story of my life", and "steal my girl." last night, thousands of those die-hard fans camped outside new york city's central park, all to stand feet away from harry and his band mates. their new single, "drag me down", how is it different? >> we've slowly introduced our fans to different music over the years, and i feel like this is the place where we want to be now with our music and stuff. it's quite an eclectic sort of sound. >> reporter: the new sound was a

record breaker, according to spotify, "drag me down", was streamed more than 4.75 million times on the day of its release. the song is part of a new album expected later this fall. >> there's different tracks on there, one that reminds me of toy story. but it's like a modern version of the "you've got a friend in me", song which i love. >> reporter: it will be the first album since zayn malik left over four months ago. his departure left many of one-d fans wondering if they would stay together or split up. >> i think when any team loses a member the team bond a little stronger. we've got and little stronger, as long as he's happy doing what he's doing, we're happy too. >> reporter: and louie will soon be a dad. >> i want to congratulate you on your upcoming fatherhood. >> thank you.
