If you move out of your home while it's on the market, you'll expect your real estate agent to handle the showing in your absence. Bout how do you avoind the unwanted attention from uninvited intruders?
There are many suggestions to offer to increase your security. While your agent likely won't have time available to constantly monitor your home, you do have the option of registering with the local police department so that officers assigned to your neighborhood can keep an eye on your home and perform security checks as needed (generally at no charge).
If you have a security system already installed, be sure to notify your service that the house is empty, and provide an emergenct contact number. Also employ a caretaker for the grounds to keep the yard clean and maintained for a more lived in look. Stop your newspaper deliveries and make sure your mail is being forwarded to your new address before your big moving day.
Don't leave anything valuable behind and be sure to program all of the lights on timers, inside and out. An overlooked issue, however, is to not leave the lights on all night, as that is actually an obvious clue that no one is home.
Some simple planning now can save you untld worry and stress later.
Enjoy your move!
