First tip:
What’s one of the most important things you can do when traveling? Keep your home safe…
Make sure someone is watching or taking care of your house. Nothing says there is no one home like newspapers lying in the driveway or a stuffed mailbox or a lawn that really needs mowing. (unless of course you always live like this!)
Be careful what you post on Facebook or Twitter. Telling everyone that you are leaving for three weeks in Europe may be an invitation for someone you don’t want checking out your home. You can always post those photos once you get home.
