Hello SH 1982.
I would recommend that you really think before procedding with your idea of buying so many hectares, and hiring staff to work your land. The Paraguayan mindset is very different than that in Europe or the USA (where I am from). I had a small farm (6 hectares) with a single employee to take care of my milk cows. pigs. chickens, etc. In 5 years I had to replace the employee five times. All were lazy, envious, and cunning liars, who stole from me more the better I treated them. You really need to experience things here first hand BEFORE you make such a big purchase.
Please dont get me wrong. I love Paraguay, and have been here full time with my wife and son for over 3 years. I also recommend buying property. I bought 3 pieces of property, starting with 3 hectares, then a house with 3 hectares, and finally a 1.5 hectare piece. I have since sold all of my animals and equipment and put the farm and the other properties up for rent. The farm I bought in 2008 for $30,000 is renting for almost $6,000 a year. A return of almost 20% after expenses are added. The 3 hectares I bought for $7,500 in 2008 are renting for almost $3,000 per year. These are of course not large sums of money, however the percentage return on investment is huge.
I recommend buying many smaller rental properties and renting them out to supply your income.
