1. Neighborhood Watch. It never hurts to ask a neighbor to keep an eye out for any suspicious activity while someone is away. This is great since it can be for something as short as a few hours or for a couple of weeks. It also may help to improve the relationships between your tenants if you have an apartment complex or their neighbors if you rent out a house. It never hurts to have an extra set of eyes keeping a watch for anything unsavory going on.
2. Mail Issues. If your resident is going to be gone for a couple of days, it is always a good idea to have them ask someone to hold onto their mail while they are gone. More than a day or two of mail is something that burglars look for to let them know that no one is home, so doing all you can to prevent that from being noticed is worth a shot.
3. Light Timers. If a criminal has been watching a house to rob it, they likely know the habits of those who live there. If they suddenly are not turning on lights at night, that may be a big tipoff that there is no one home. Supplying a cheap light timer or two for your tenant may make a world of difference in helping prevent your rental property from being a target of a burglary.
These are some of the most simple ways to help your tenant keep themselves, their possessions, and your investment safe. While some of your tenants may do these things automatically, it is never a bad idea to ask them even if just as a reminder. After all, once vacation time comes up, we are normally far away from home in our minds.
