This is basic case where bad sponsor doing high risk investment in bad times …I was one of the small investor for very large SF rental fund out of Florida but got litigated by SEC three years ago and handled by receivership court now.three years later we got at least out 80 percent money back LOLBtw , every new kid can make money in 2016, but if they can survive 2022 that’s your guy :)So don’t afraid to make lawsuit against these company …Carlos seems to be more experienced in this than me, so feel free to disregard my comment at your discretion.

I'm a civil engineer, and for example, I do the civil engineering/permitting for many Gas-Station & Convenience Store.
