Cayman Islands is a tax haven. They do not tax income, capital gains or inheritances. There is an import duty and everything is imported so cost of living is high. Price of real estate is high. Crime rate is low. Infrastructure is very good. They do get hurricanes and bad ones at that. Their banking secrecy is hysterical so bank elsewhere.

The Caymans are in many different tax treaties and will share information, so forget privacy here. Their corporations and trusts are expensive and have no outstanding feature so look elsewhere like Panama. If you invest $250,000 in real estate (probably a one bedroom condo) you can get a residency easily. It is one hour by plane to Miami. If you have to ask how much the airfare is the Caymans are not for you. This one works if you have substantial assets. Other than fishing and going to restaurants and the beach (diving) there is very little to do in the Caymans.
