You might ask, 'why do I need renters insurance at all?' but that would be the wrong attitude to have. While many would view it as an extra bill that they don't need, renters insurance is essential. Many apartments are at far more risk of fire damage, water damage, theft, and any other common type of damage than ordinary homes are. With all of this in mind, it's far cheaper to be insured and protect against damage that will end up being inevitable one day.
Renters insurance is essential, and if you're already renting or are going to be soon and don't have it, it's probably a smart idea to at least get a quote and see what kind of policies and options are available. And remember, there are all kinds of short options or month-to-month renters insurance available if you don't want to pay for a full policy!
