Back now at 7:42. Outraged homeowners in a wealthy malibu neighborhood fighting to prevent their neighbors from keeping tigers in their backyard. The neighbors say they're not breaking any laws but the homeowners needless to say feel it's a risk to their safety and also their property value. That is know not a tiger. They got more than tiger. ABC's Rebecca Jarvis will tell you more. ? Reporter: High above malibu, California, amidst the cliffs and views is a rustic neighborhood called deer park. Nanette and Dan thought their home here was their castle. Until one day they say something reared its ugly head. The threat is something they never anticipated. Ooh. Reporter: A white siberian tiger, trainers irina Howser and Sophia creshak brought one in a temporary cage to show us. Around this entire area would be a perimeter fence with barbed wire on top. Reporter: The sisters thought it would be a formality to get a permit to permanently keep the tigers on their property. They thought wrong. They are our closest neighbors and a tiger can get here in 30 seconds. Reporter: The family lives a few hundred yards away. We're a young family. Last thing we want to worry about is tigers getting lose and eating our children. Reporter: They weren't the only ones upset. Signs went up all along the roadside. Deer creek not tiger creek. As mothers we empathize. It is safe. No tiger has ever escaped a property and gone to a neighboring property and killed anybody. Reporter: But Dan bercu isn't just a concerned father, he's in the real estate business. A property adjacent to a wild animal preserve is basically worthless. Reporter: It's come up before. It's legal to own exotic animals of some sort in 29 states so homeowners in a Cincinnati neighborhood had to worry about this 16-foot python and imagine how residents at this mountain pleasant, South Carolina, apartment felt when they discovered this skin from an african viper. Going through what we've gone through and maybe die from some rare african viper. Reporter: How do you think they felt about a girl parading her pet bear cub on the front lawn. Animals and real estate, never a mix. From a barking door next door will diminish your value to a lion down the street. What you got to do is check out the neighborhood before you make the offer and most people don't. Reporter: For "Good morning America," Rebecca Jarvis, ABC news, New York. I love that. Barbara Corcoran. Barking dog, the lion down the street. A common problem. Wow. You can see more of this incredible story. Rebecca's report tonight "20/20" on ABC 10:00, 9:00 central. Who is one of the hosts? I've heard of it. I heard he has fabulous hair. Just a clue. Coming up, the lady in red.
