Many apartment dwellers don't think hard enough about the possibility of theft.
It's probably not too hard for someone to get into your building, and you may also need to worry about the other residents of the building who you may not know well, but may know your routines and may even have seen what you own in your apartment.
The first step is to have good locks on your apartment door and always use them without fail, even when leaving your apartment for a couple of minutes.
This will seem troublesome at first, but will eventually become second nature and you'll do it without even thinking about it.
It's also a good idea to look at the external windows and understand which ones someone could access and try to enter your apartment.
These windows should be secured with good locks.
It's also a good idea to make sure that nothing of substantial value is visible in your apartment from the outside.
This may mean keeping valuables out of site, or using curtains so that people cannot look in from the outside.
In addition to these preventive measures, it's also a good idea to pay for renter's insurance.
This will cover the replacement of stolen possessions if a robbery does happen.
It also covers your liability in case you cause substantial disaster or damage in the apartment.
In most places, this will cost you only $100 to $200 a year depending the amount of coverage, and it's a great safety net to have in place to ensure that a robbery does not financially destroy you.
