Each renters insurance policy comes with a limit, and this limit is the maximum amount of reimbursement provided by the policy.
Take a look at each policy's limit, and choose a policy whose limit provides enough coverage to fully reimburse the cost of any valuables.
Next, consider whether reimbursement is based on actual cash value or replacement cost. Reimbursement based on actual cash value, accounts for depreciation. For example, coverage on a stolen five-year-old TV would offer reimbursement for the fair market value of that TV, which would likely be significantly less than the cost of a new one. With renters insurance policies offering reimbursement based on replacement cost, the owner of a stolen five-year-old TV would be reimbursed for the cost of a brand-new model.
