I really like the projects that have backing in real world assets so I hope this one works out good also. Actualy there are a few alternatives. One of them is in my signature.
What I'm missing here is quicker response from devs. I have unanswered question on page 20, and I also noticed a few questions about US regulation which were not answered completely.
On the end I don't see a big problem if perhalps it turns out that real estates will not be able to be purchased in US. Main point that I would like to know before investing is the transparency of the ownership and value of purchased real estates.
