1. Dominican Republic: The Budget Champion

Why it tops our most economical Caribbean islands list: You'll find the Caribbean's lowest living costs without sacrificing infrastructure.

  1. Housing: $400-$800 rents for modern 1-2 bedroom apartments outside tourist zones
  2. Food: Local markets offer $200/month grocery budgets (imports cost 2-3x more)
  3. Transport: $1 bus fares vs $25/day scooter rentals
Pro Tip: Las Terrenas offers beachfront living at half Punta Cana's prices. My expat friend lives well there on $1,800/month.

2. Grenada: Affordable Citizenship

While not the absolute cheapest, Grenada's citizenship by investment program gives exceptional value at $150,000 (vs $200k+ elsewhere).

  1. Monthly Budget: $2,200 covers comfortable living with healthcare
  2. Key Savings: Rainwater harvesting cuts utility costs by 40%
  3. Bonus: Visa-free access to 144 countries including China/Russia

3. St. Vincent and the Grenadines

This underrated chain offers 32 islands with varying costs. Avoid Mustique ($15k/month) for Union Island ($1,500/month).

  1. Best Value: Chateaubelair offers $60k beachfront homes
  2. Digital Nomad Visa: Valid 1 year, no income requirements
  3. Hidden Perk: No property taxes for foreign buyers
