Among the three main U.S. Virgin Islands, St. Croix is widely considered the cheapest to live in. While the cost of living across the entire USVI is high—roughly 10% to 20% higher than the U.S. mainland due to the fact that almost everything must be imported—St. Croix offers more affordable real estate and rental options than St. Thomas or St. John. This is largely because St. Croix is the largest island in terms of landmass, allowing for more inland development away from the expensive waterfront. It also has a more diverse economy that isn't as exclusively tied to high-end cruise ship tourism as St. Thomas is. Additionally, St. Croix features more local agriculture and "big box" shopping options that can help keep grocery costs slightly lower. St. John remains the most expensive due to its limited private land and status as a national park sanctuary. However, prospective residents should still prepare for high utility costs, particularly electricity, which is significantly more expensive than on the mainland.
