The Cayman Islands is significantly more expensive than the North America average (+106.5% overall, +81.9% excluding rent), making it one of the region's priciest destinations. It is best suited for high-earning expats, remote workers with strong international salaries, or those with employer relocation support. The no-income-tax policy and superior quality of life (index: 196.8) can offset costs for qualifying individuals, but budget-conscious relocators should consider more affordable North American alternatives.
