Argentina
Last but not least, one of the cheapest countries to retire is Argentina.
This nation offers the ideal balance of convenience, affordability, and refinement. It mixes breathtaking scenery with elegant cities and towns, and its literature, music, and art can satisfy even the most discerning aficionados.
Argentina offers a significantly lower cost of living than the UK or the USA for the majority of items. Rentals in the most upscale neighborhoods of popular cities may be an exception. However, if you compare like with like, you should be comparing renting such apartments with renting similar properties in Manhattan or Knightsbridge; you'll realize that Argentina is by far the more affordable option.
Food and fine drink, such as some gorgeous red wines, are considerably more reasonable, and if you venture outside of the tourist areas and pick up the local dialect, you will be treated more seriously and your money will go much further.
