Retiring on a budget of $1,000 per month is challenging but feasible in certain countries or regions where the cost of living is low. Here are some options that might work for such a budget:

1. Thailand: In smaller towns and rural areas like Chiang Mai or Isaan region, you can live modestly on this amount. Street food and local markets offer affordable dining options.
2. Vietnam: Cities like Hanoi or Ho Chi Minh City have lower costs compared to Western cities. Accommodation in hostels or budget hotels and street food are inexpensive, allowing for a frugal lifestyle.
3. Greece: On some of the islands or less popular regions, you can find affordable living options. Renting small apartments and eating local dishes help stretch your budget further.
4. Portugal: In smaller towns outside major cities like Lisbon, rent and daily expenses are lower. You might need to adjust lifestyle expectations but it’s possible with careful planning.
5. Philippines: Cities like Cebu or Davao offer a very low cost of living. Sharing accommodation or renting small apartments can keep costs down significantly.
6. Mexico: In less touristy areas, you can find inexpensive housing and local food options that allow for a frugal lifestyle. Northern states often have lower costs than the more popular southern regions.
7. Colombia: Cities like Medellín offer relatively low living expenses with affordable housing and cost-effective dining options.
8. India: Certain cities or towns, particularly in rural areas, can be quite affordable. Renting a modest apartment and relying on local cuisine can fit into this budget.
9. Romania: Cities like Cluj-Napoca have lower costs of living compared to Western Europe. Basic accommodations and meals are affordable here.
