I paid a deposit. Do I still need renters insurance?
Yes, because they do opposite jobs. The deposit is the owner’s protection against damage you cause. Your policy is your protection for your belongings, your liability and somewhere to live after a loss. Almost nothing about them overlaps.
Will my policy pay my deposit back?
No. The deposit is a contractual matter between you and the owner, governed by Arizona rules on what can be withheld and when it must be returned with an itemized statement. That is a tenant rights question rather than an insurance one.
What if I damage the apartment?
Deliberate or ordinary wear comes out of the deposit. A sudden accident that causes real damage, such as a fire or a flood you caused, is a liability claim on your policy, and those figures are far beyond any deposit.
