Getting a more precise idea of what it is that we are looking for

Very good stuff, thanks @Lee.

Here are some co-living and co-housing spaces we visited in the past, with our own notes about them:

None of these is a good model for us, but re-reading them helped me focus what we do not want, and what some of the roadblocks might be.

I am totally down for this.

If I read your words correctly, the terms of partnering up would be these: we approach a real estate developer or reseller (like Cohousing Projects). The deal is: if they start a project in a building that we like, we are willing to be its first buyers, and the nucleus of its future community. Is this correct?
