I would recommend getting a non-owners insurance policy
with an SR22 added. This will provide state required coverage to drive while you don't actually own a vehicle and don't have a need for a traditional auto policy. This will also allow you to build up your continuous insurance discount
, making the rates available when you need to insure a vehicle again much more affordable. Your best bet would be to contact a local agent in your area for a quote since non-owners policies typically aren't available online.
