In theory migrating from one security deposit insurance to another is relatively simple. You can simply apply for a cheaper security deposit insurance offer and, once approved, give notice on your existing insurance policy. However, you have to consult with the property owner or manager first and get their approval. This makes the process more time-consuming.
You should also pay attention to the notice requirements of your existing insurance policy. Make sure to give notice on time, and make sure that your new security deposit insurance only begins when your existing insurance expires.
You are generally required to pay the insurance premium for at least one year in advance. Because of this, your new insurance should only begin after the prepaid term of your existing security deposit insurance ends.
