6 Tips for Showing your Home Safely

Make sure valuables are locked up or off-premises during showings and open houses. Jewelry, cash, liquor, checkbooks and credit cards, prescription drugs, keys and other small valuables should all be out of reach when your home is being toured. Safeguard your personal information, too - lock your computer and filing cabinets and don't leave bills that might show your account numbers lying out.
Choose an agent who uses an electronic lockbox system. Modern electronic lockboxes restrict access to licensed real estate professionals and track every time someone uses the lockbox to enter your home.
Don’t show your home by yourself. If you wouldn’t normally let a stranger into your home and show them around just because they asked, adding a For Sale sign to the yard shouldn’t change that. Direct any inquiries about the property to your real estate agent, who will pre-screen buyers and collect contact information before bringing anyone through. If you opt to sell your home without the help of a real estate agent, this still applies – insist that all showings be prescheduled, collect contact information and verify drivers licenses of potential buyers before they come for a tour, and try to have someone else there any time you are showing your house.
Either take your pets with you or keep them kenneled during showings. This prevents both the possibility of your pet getting loose during the showing and/or attacking an agent or potential buyer. Even usually calm animals can sometimes get defensive when unfamiliar people are in their space and you could be held liable for any injuries.
Check that your home is securely locked up after showings and open houses. Doors and windows might be left unlocked unintentionally by distracted buyers trying to take in everything about your home, or would-be-thieves who intend to come back and use the entry later. Either way, you can help keep your home safe by doing a quick walk-through to check the locks after any tour.
If you are selling a vacant home, consider a home staging service. Staging a home can help keep it from looking empty to a casual passerby and decrease your chance of a break-in. Use timers on the lights to boost the illusion that someone lives there. Bonus: According to the National Association of Realtors, “staged homes sell 80% quicker, and for up to 11% more money than non-staged properties.”
