charles. argentina is way less on a cost basis. although you need to buy an apartment. its a good time for that. 100,000 to 150,000 plus remodel costs for a good neighborhood. your retirement in dollars, social security, will go along way in buenos aires. i do think you can work out medical expenses. at present i count on being stabilized out of pocket and retuning to the US for treatment. i bought an apartment 20 years ago in BA. today i might make 30 percent. its not worth selling. whats good is it only costs me 1500 a year including electricity, canble, building expenses, and annual taxes. there is no comparison. the taxes on my US apartment is 1600. building expenses are 300 a month. i was told a kilo of carne was 6.00. not even close. 8 oz is 20.00. ba is a great culture and great people. kust depends if you want a cultural experience or the same old thing. your choice. the dollar will always make your life comfortable in south america regardless of country. colombia is another example
