Those returns are a bit too good to be true: 12% *guaranteed* on a real estate project is fairly ambitious. All their return assumptions are very enthusiastic.
A few seconds' googling shows that their Hawaii project actually exists, which is a step up from the usual rubbish you get from these sort of companies, but it's just run into a massive snag: Hawaii's Land Use Commission has just
yanked the residential zoning on the development, and
reverted it to agricultural zoning - which means that they can't build the condos, and if they do build the condos they can't get them certified as ready to move in.
Yeah... they seem to be trying to raise money for a development project that's already been shut down.
