Update your household insurance
Most of us are (hopefully) lucky to have good, respectable neighbours, but knowing who in the neighbourhood will really have your back while you're away is a priceless asset. So, let your dependable friends next door or down the road know that you'll be away, and ask them to keep an eye on your place during the time. You may even want to give them a spare key in case of a household emergency and/or ask them to look after your pets while you're away.
