Well you have to check the company, The company belong to the group Newling Capital, the owners are Manuel Estruga and Damian Lopo, the CEO is Mariano Nejamkis the former founder and CEO of ZonaProp.com. But of course that dosn't really say nothing.
About the project in particular, i would say is quite solid, i have a friend working in vaca muerta, salaries there are astronomical starting from 50-60.000 pesos per month the lower lower of the positions and almost 90% of the people there are single males without families so with a lot of spare money to spend, so renting, restaurants, prostitutes, and drugs sell a lot in that place. I checked the renting price and is around the same amount as they claim with a steady growing path.
Now the problems of what is not properly explained on the investment, they claim a ROI of 25-35% in 2 years, that makes a return between 12.5% - 17.5% per year in dollars, but that is over the investment, not the real ROI, because if you check the details you have expenses and commissions that goes from 7%-10% of the initial investment (they only calculate the ROI of the original investment without considering the commission and cost involved on the transaction), so the real ROI considering the higher possible commission is 14%-23% and the lower possible commission is 17%-26% that is over a period of 2 years, letting you a return per year of 7%-11.5% to 8.5%-13% per year, that is a very probable ROI for this type of investment, my father buy lands and construct on them and he obtain ROI in dollars superior to 30-40% a year, but of course he do it by himself and he knows perfectly where to buy, how to deal with successions, and everyone in the region that wants to sell something goes to him so he is already well placed in Patagonia plus he has his lawyer studio placed on the region.
The biggest problem in Patagonia is the lack of work force, you have to pay a lot more than anywhere else in the country for a person to do the same construction job, and most of the people that work in construction are always busy unless you manage to have a group of people that work only for you.
That is my insight on the the topic, in any case you have to check yourself always the numbers and the small letter, the laws for crowdfunding are advancing and once the CNV start regulating them it would be ready for an explosion, today they release a new law for crowdfunding, i need to read it later on this day, but until now it depends a lot on the contractor, there where a lot of very successful projects like the boat parking in Tigre that where excellent investments but of course there where projects that where not so successful or shady contractor as well.
Hope this helps to clarify a little bit the scenario, but the best you can do is to do your own research, i cannot do a deeper research in this moment to busy with other things at the moment.
