In today’s market, when your house goes on sale, you become vulnerable to the entire world.

That “For Sale” sign on your front lawn and your listing on real estate websites let everyone know that your home is for sale. While this attracts potential buyers, you could also make your home a target for people with bad intentions.

From realtors who steal undergarments from the drawers of their clients to teens who throw parties in mansions they found on real estate websites, there is no limit to what could happen in your home when you sell it.

“You’ve got to be vigilant when your house is for sale. You can’t just sit back and assume that all’s going to be OK,” real estate expert Brendon DeSimone told ABC News’ “20/20.” “Nowadays, with so much information online, some marketing remarks for realtors say, ‘Vacant and ready to sell,’ with pictures online. People know it’s for sale, and people can tell when a home is vacant. When your home goes for sale, you’re kind of living on eggshells.”
