How to stay safe while working with clients: A cautionary tale about cyber-stalking

Katie Gambla had only been working as a real estate agent for about a year, when in spring of 2018, she got her first phone call from a man posing as a potential homebuyer.

But after speaking briefly, she realized something didn’t seem right. Instead of asking the typical questions she’d become used to hearing, the man on the other end of the line wanted to know when Gambla was typically in the office and where she would be at open houses in her hometown of Beaufort, South Carolina.

“I asked, ‘Is there a property you’re interested in, specifically?’” she said in a recent interview.

From there, he began babbling and hung up, but the calls didn’t stop there. The man, who was later identified as Andy Castillo, continued calling repeatedly from different phone numbers and leaving sexually explicit and threatening voicemails.

Gambla went to her local police department and reported the calls, but Castillo used a so-called voiceover IP system that allowed him to conceal his identity and the location from where he was making the calls.

“I’m a pretty safety conscious person, in general,” Gambla said, but the calls made her fear for her safety. “When this all started, I was assuming he was here, so I was more on guard.”

She began taking new precautions, such as letting others know when and where she was meeting new clients. Gambla also changed her routine when showing properties, particularly making sure she could quickly exit the home and parking on the street, rather than in the driveway, so she could not be blocked in by another vehicle. She also began taking her boyfriend or a male listing agent to meetings with new clients.

Following numerous complaints from various real estate agents across the country about the anonymous calls, law enforcement officials tracked Castillo down to his apartment in Lubbock, Texas, and arrested him on Jan. 6, 2020.

The ensuing investigation revealed that Castillo had been making the threatening calls to more than 120 real estate agents in different cities throughout the country, and a DNA test connected him to the 2003 murder of Cynthia Palacio, a 21-year-old Lubbock resident, and her best friend, Linda Carbajal, 21, who was murdered in 2004.

Castillo was incarcerated and awaiting trial for capital murder in the two cases when he died of COVID-19 in 2021.

Gambla and several other agents targeted by Castillo were highlighted in the television show “Devil in the Web” earlier this year on the Investigation Discovery channel.

She said that having worked in the business for several years now, she finds most of her clientele is based on referrals and past clients, but as a rookie agent, she was much more exposed to the unknown. She advises new agents to “cultivate a more referral-based business so you’re not meeting with as many strangers.”

Also, vet new clients when you’re speaking with them over the phone during that first phone consultation, she advised. “I ask, ‘Who can I thank for giving you my information?’ and people usually have a legitimate answer for that,” she said.

Gambla can now more easily determine whether potential new clients have been following the market, and she asks if they’ve already met with a lender. New agents often are eager to jump in the car and rush over to show a new client a house, but that eagerness can put you in a precarious position, she said. “I think a lot of new agents get excited about those kinds of calls, but it’s smarter from a safety perspective to pause,” she said. “If people are really interested, they’ll work around your schedule.”

The National Association of REALTORS® offers a number of tips on how to stay safe on their REALTOR® Safety Program website (, which includes the following:

• Always meet new clients at the office or in a neutral location, like a coffee shop.

• Share your schedule with a colleague, assistant or family member.

• Communicate safety concerns on your listing (poor cell phone signal, etc.).

• Do not overshare about your personal life.

• Do not host open houses alone.

• Check your cell phone battery and signal before heading to an appointment.

• Direct clients to walk in front of you when touring a property, do not lead them.

• Never go into attics, crawl spaces or garages, where you could be trapped.

Best tech tool for new agents to grow their business

It’s no secret that the real estate market is flourishing, which is why so many people are getting in daily. Most successful real estate agents can offer far more returns than drawbacks of working in the industry. However, one aspect of the real estate industry that is barely discussed is the startling number of agents who do not succeed in this industry. The proportion of real estate agents who fail during the first five years varies depending on the source, but it is typically between 85 and 90%. Shockingly, roughly nine out of 10 new agents can fail. Nonetheless, this doesn’t mean you shouldn’t go for it. With great determination and having the right tech tools in hand, you will have a good chance of being among those remaining 10-15% agents who succeed.

What new real estate agents should know

The first year of your career is the most challenging. The good news is that you don’t have to do it alone — technology will simplify things for you. A good CRM/database is the most important thing to start with. It gives you a solid foundation to build upon your existing sphere of influence and prospect for new clients/businesses. Then, as you expand and grow, it is essential to have a good tech solution to help simplify your workload, keep your email communications organized, streamline your workflows and increase your productivity.
