Brazil’s coast-line is for sale and Argentina, still reeling from the economic collapse, also has land deals. Westerners with cash to spare are heading out there to buy land. Better in our hands than some faceless multinational.
Prices vary, but can be as little as $25 per acre. Life is cheap wherever you are outside the big cities in South America, and you can grow food and live self-sufficiently. The climate is mostly temperate in Argentina but gets cold and arid as you go up in the Andes. The coastal plains are fertile and it isn’t difficult to find a piece of land with a stream or on the coast. In Brazil avoid the Nordeste, the dry north-eastern region.
