After the cost of tuition and books, a lot of college students may not be so eager to spend even more money to buy renters’ insurance. This might, usually, be a mistake.
For a student living on-campus, they’re not probably worried about renters insurance. That is if their parents’ homeowner’s policy will cover any loss or damage to personal items. But, verify if the parents’ policy does include “off-premises coverage”. It’s not guaranteed.
