Last spring, Nancy Broden and Michael Fortson were having breakfast at the Town's End Bakery, wondering how to make their life make sense. Both tech workers in their 40s, they had a pretty good setup on paper: Broden was a veteran of Twitter looking for her next project, and Fortson was making a good living developing iPhone apps. The couple owned a two-bedroom condo at the Brannan, close to AT&T Park, where they were regulars at Giants games. But they had bought in 2007, right at the pre-recession height, and the squeeze of the mortgage payments began to make them feel like a support system for their condo, not the other way around. "It felt like the tail wagging the dog," recalls Broden. Without thinking, she blurted out something about buying an Airstream. "Then I was like, 'Oh, wait, no, I don't want to live in a trailer,'" she says. "Just because there's that weird stigma that we're living in a van down by the river."
