Well the point is clearly made in the video... I think you're thinking of co-working space. A hackerspace is quite different http://en.wikipedia.org/wiki/Hackerspace We do have the option of going with a real estate investor, however we think it will be more fun to get the community involved from an early stage and do a crowd funding campaign!
Why do we need spaces specifically marketed to "hacking"? Hacking requires a computer, a table, a chair and electricity - just about any real estate fits those parameters.
On top of it 1.5 million through crowdsourcing for this sort of thing I have to doubt would come even close to cutting it for getting things off the ground. Syndication through real estate investors would probably give you a much better shot.
