My guess is that the rent isnt gonna cover the cost of the land. The people who make money farming, in both Argentina and the USA, inherited the land. You cant make any money paying that much per acre. And people who have 3/4 of a million to spend (the cost of that land and a house) are going to find existing estancias that already have electricity and water. Farming in Argentina is a very rich mans game. Sure, there are little truck farms that have 1 hectare and grow fancy tomatos for restaurants, but soy, corn, sunflower oil, and beef are businesses that take millions to get into, and are almost all on land that has been in a family for generations.That's if you plan to live there ..? otherwise you just rent the property to a farmer to continue with the current crops, looks all planted with soy..?
A great book to browse, at, say, El Ateneo when it reopens, is this one- see how the other 1/10 of 1 percent lives.
