Cayo, Belize. Belize is one of the quirkiest countries in the world. Geographically, Belize is in Central America, yet its strongest ties are to the English-speaking Caribbean. Belize is Caribbean, Central American and, thanks to its history as a former colony, British. Belize City's roadways are built around a system of roundabouts, but shops alongside them sell rice, beans and tortillas still ground by hand.
English is the country's official language. The 350,000 people populating Belize today are diverse and include the descendants of migrants from Britain, Mexicans, Guatemalans, Hondurans and Nicaraguans mixed with current-day generations of the Maya who originally inhabited this land.
Belize is a sunny country that's easily accessible from the United States and the folks all speak English. It's also one of the easiest places in the world to establish foreign residency, as well as a banking and tax haven. You could live and run a business here tax-free.
On the other hand, this is a small country where the infrastructure is developing. The cost of living can be affordable. However, if you want to live a more developed world lifestyle that involves buying lots of things not available or produced locally, be prepared to pay an inflated price for imported goods.
