At this time 272 people want to invest, via Fundrise, in this former small office building. So far $691,000 has been pledged, well over the $300,000 goal. According to the Washington Post, in the first 2 hours of being available, $308,000 was raised. There are 28 more days left to raise money, so it will be interesting to see how far it will go.
The concept is interesting. However the problem is you can't really sell your shares of a project like you could say shares of PEPCO. Also I didn't really see anything in the FAQ about what happens when the fundraising goal has done what is happening, and twice as much has been raised.
