Banking the Sunshine State

Florida ranks as the number one state in the nation for net migration. Florida’s $800B economy is 70% larger than any other state in the southeastern United States and maintains an attractive tax policy. If the Sunshine State was a country, Florida’s economy would be the 18th largest in the world – larger than Saudi Arabia, Poland, Chile and Argentina. Why invest in Florida?
