Real Estate in Space?!

[William Brown]

A foreword: this isn't a normal thread. Creative thinking and solutions welcomed. I've got my whole life ahead of me. While I don't believe the technology is there quite yet, I predict that in the next 50 years the tech will be there to live in space. Among the growing problems on Earth, climate change, population explosion, and international policy, life might not be sustainable for humans. So we need to branch out into space. One of my biggest dreams/ambitions is to pioneer real estate in space. I know SpaceX has a program headed in that direction, and I think they will make considerable progress in the next couple decades. What do you all think? Possible or not, what ideas do you have?
